    The Ordinary - Hyaluronic Acid 2% + B5

    The Ordinary Hyaluronic Acid 2% + B5 Reviews

    Great product especially for the price
    I've been using this one for two and a half months and I'm loving it so far. I definitely feel a difference. I've got a lot of dry patches on my face and they're almost gone since I've started using this product. I do think it feels a bit silicone-y but it doesn't bother me that much. I would buy this again but I'm also looking forward to try other Hyaluronic Acid serums.
    Does not hydrate at all.
    This product is amazing! After only two weeks, the difference on the skin is so great! It is smoother and brighter, truly a must!
    Little price big results
    A must have... It absorbs fast, you can mix it with any moisturizing cream and it's effective! I bought 3 already and used them all.
    Great item, I would recommend
    Amazing Product!
    This product is amazing! After only two weeks, the difference on the skin is so great! It is smoother and brighter, truly a must!
    This is one of the best product that I have tried. After a month of using, I see changes in my skin. I use this serum in my morning and my night routine. It makes my skin firmer and hydrated.
    Makes my skin brighter, firmer
    Love this product. A keeper for sure.
    I have used this every morning and night for the last 6 weeks (only just ordering my second bottle now!) and I have seen a big change in my skin. I have always suffered with dry patches but they are totally gone now. My skin feels so dewy and soft. I use this alongside retinol and it has worked a treat! I have recommended it to all of my friends.
    I absolutely loved this product. Firstly I have an oily, acne prone skin, tell me what not I have tried since my teens?! I apply this serum right after cleansing my face followed by another ordinary product, and sunscreen haven't seen any major breakouts since I have started this (probably a month now). My skin looks hydrated and youthful after application. Will definitely repurchase.
    Skincare that really feels like skin CARE
    I’ve just started my second bottle of this stuff. As someone who gets more than the occasional spot and has been inundated with them for so long, this really did help me on my way to making it much better. Is this going to work instantly? No. Is it going to work without the aid of other blemish/ corrective skincare in your routine? No. But it really does feel like you’re taking care of your skin. I use it every chance I get - at least twice a day (which I don’t think you’re supposed to but whatever) - and it really soaks in. It’s more hygienic than other brands due to the dropper applicator so you don’t spread the bacteria, etc, and it goes far - and it’s so cheap you can afford to use it literally which is amazing and sooo worth it! DEFINITELY worth an add to the skincare collection. Adore the stuff!
    Love this
    I absolutely loved this product from the first use. I put it on straight after washing my face and it feels so nice, definitely hydrating. Wish it came in a bigger bottle!
    Love love love!!
    This is my second bottle and I can't stop using it! Love it! I use it after I cleanse and top it off with the rest of my skincare.
    I suffer with bad acne and dehydrated skin. This product has literally turned my life around. Just about to order my 2nd bottle!
    Very, very good for dry skin
    This has done miracles for my super dry and always chapping skin. I use this under my moisturiser every night and my skin is looking really plump, fresh and actually moisturised! I have tried using even vaselines, etc for my dry patches in the winter but this fixed them all. Currently on my second bottle, wouldn't exchange it for anything!
    Great Product
    I like it and it makes my skin feel great.
    Been using it for the past 4 weeks and I absolutely cannot olive without this now!
    I don't love this stuff. Maybe I didn't give it long enough for my face to adjust, but it has a weird texture, and kind of seems to sit on my face. It does moisturise, but not as well as the Aurelia probiotic concentrate (holy grail!), which I was using before I bought this. I still have most of a bottle so if I had nothing else I would possibly use it, but honestly I think it broke me out a bit and it just doesn't feel great.
    Pretty good!
    I have extremely dry and sensitive skin so I wasn’t expecting much but thought I’d give this a whirl! I put it on every morning and night after cleansing, I’ve learnt you don’t need much product but you have to apply it very quickly otherwise it stiffens and is hard to spread. Also, I find that I need to wait 5-10 mins before moisturising otherwise the liquids go weird and mix together. A weak point for me would be that I can’t seem to use it if I’m going to be putting foundation on that day as it makes my foundation peel off in tiny flakes (this might just be me though)! Having said that, when I do use it, it definitely does hydrate and plump my skin and for the time the tiny bottle lasts at that price, it’s well worth the buy :)
    Definitely works!!
    I have purchased this product twice now and can safely say it works wonders. I was sceptical since I have extremely dry/red skin and nothing ever seems to work but, I was pleasantly surprised to see that this product, along with an intense moisturiser from The Body Shop, did wonders for my skin. Admittedly, I think I use more than the recommended amount so the bottle doesn't seem to last me as long as it should however, that is just a personal preference. It is the first product to leave my skin feeling moisturised and plump in the morning as well as reducing my redness almost completely. Considering the price point of this product and how well it works, I would definitely recommend it to anyone.
    Dampen face with mineral water before applying......
    I'm a serum fan. I've tried many different Hyaluronic acid serums too. I have very dry, sensitive skin. "The Ordinary", Hyaluronic acid is an amazing skincare product. It's definitely great for dry skin. My skin feels plump, hydrated and calm after I used it. Apply it only on damp skin. It will lock in the moisture if you have dry skin. I spray thermal mineral water or, Omorovicza mist on my skin. Apply your daily moisturizer after that. Needless to say, it's great value. You'll love it.
    Doesn't work
    I've got combination skin, but this just doesn't work. I use this with the L-asorbic Acid Powder, but it's doing no good for my skin.
    I’ve used 2 bottles of this serum now and have mixed views on its efficiency. It supports hydration when used in conjunction with a moisturiser and my skin condition has definitely improved, however layering this product with oils, sunscreen and makeup, resulted in peeling despite leaving 10 minutes in between for absorption. I isolated it to this product by removing each from the daily routine to see which was the culprit. I’ve since purchased a more expensive alternative which doesn’t do this. So for PM applications I still think this is a great value product in good packaging but for me not suitable for layering with other things. It’s also very sticky/tacky in consistency which is a bit strange.
    It's "okay"
    Feels a bit weird and slimy to begin with - I let it soak in then follow with moisturiser. I don't think it's remarkably better than normal moisturiser. I doubt i'd buy it again.
    Brilliant product
    For this price you can’t go wrong. I bought this to combat dry dehydrated dull skin and it is working wonders. I use morning and evening after cleansing. The texture is not quite slimy but thicker than you would imagine a serum to be. Best applied to completely dry skin or it won’t absorb properly. I follow this with The Ordinary Natural Moisturising Factors cream after leaving this serum to soak in for a minute or two. It doesn’t affect my make up at all. My fine lines look plumped out, my skin is actually glowing and my stubborn dry patches haven’t reappeared. I’m amazed and will be stocking up again.
    Hyaluronic Acid 2% + B5
    I didn't like it too much. It's similar to snail mucus. I couldn't do make up if I use this product, because my foundation rolls off. So I just use in for night time. But even I just touch my face I feel as a means not absorbed but turned into a film on the face, not my favorite for sure
    Love this product
    I use this in the morning after cleansing. It sinks in beautifully, and leave my skin soft and hydrated. I wouldn't say it's a miracle product, but for the price, it's excellent.
    The Ordinary Hyaluronic Acid
    Keeps the moisture locked in all day!
    Such an amazing product. Really does what it says on the box!
    This serum leaves a firm film and clumps up my mineral sunscreen when I apply it on top.
    Not impressed
    Have used many of The Ordinary products and they have never disappointed me. This one was good at the beginning but later on started drying my skin. I had a burning sensation as my skin was exposed to the sun for too long. Have to stop using it for now.
    Parfait, hydrate bien ma peau et la rend plus douce. *** Perfect, moisturizes my skin and makes it softer.
    Hydrating and non greasy
    So hydrating, but not in the same way other creams hydrate but leave your skin greasy. My skin feels smooth immediately when applied at night, and in the morning my skins quality looks so much better!
    Exceeded expectations
    I really didn't expect much, after doing a lot of research this is so cheap compared to other HA applications, but after a month of using this I really have noticed a difference. I'm 38 with sensitive skin, recently noticed lines creeping in, but have always kept a very simple and natural skin care routine due to sensitivity so I've been worried about trying new products. I went for a hydrating regime, following this with plant based squalene and the moisturiser with HA. My skin is plumper, looks healthier and my dryness and eczema are clearing up. Really impressed, I've just ordered some more and will be introducing a vitamin c and retinol to my regime as I now feel confident in the quality of The Ordinary products.
    HA Acid
    This is an excellent product and I have been using it for some time now. Having noted another 'feedback' comment, I would just say that, as recommended by the company, after applying the serum one's usual face cream should be applied.
    After reading a lot of good reviews about this product I decided to buy it but I'm kinda disappointed. It doesn't hydrate enough. My skin feels so tight after putting it on. I wouldn't recommend this product.
    Hyaluronic Acid/B5
    Amazing! Lightweight,cooling and hydrating,perfect for combination, oily or dehydrated skin. After a few seconds, you can apply your cream and makeup perfectly!! Worth buying!!!
    Poor design
    I've tried loads of HA serums and this is the worst. The product is too thick for the dropper so when you pull it out it drips everywhere and then pills on your face so little bits come off everywhere. Such a disappointment. Much prefer Medic8's one.
    Doesn't do anything.
    This product does not feel like HA usually feels.This product is very watery even though it is supposed to have large HA molecules. It does not leave my skin feeling moisturised nor does it give the plump effect or filling of wrinkles as HA products usually do. I usually love The Ordinary products but this one was rather disappointing.
    So and so
    I think this is the one product from The Ordinary which I like the least.I still use it, but I don't think I will repurchase.I have 2 other hyaluronic acid serums from Mixa(french brand) and they are better. I don't think you can find them everywhere or even if u find them somewhere (I saw products from them in Budapest) I didn't see those serums (maybe on Amazon).The ones from Mixa are more hydrating.This one isn't in my opinion. At first I used it on dry skin,but then I read more things about hytaluronic acid that it's better to be applied on damp skin so it holds the water better and it worked better,but I don't really like that much the feeling after.Maybe it's better for summer and maybe I will repurchase for this(I am not sure),but it's a good alternative for more expensive products.I would like to try the Niod or Hylamide one to see how they are.
    Very good.
    This is my third bottle and I love it, I put it on every morning and my face feels and looks so smooth and bright. I am a women over 60 and I think my skin is looking so good. I highly recommend this product.
    Love it!
    I have very sensitive skin. I put this on under my make up, and it leaves my skin feeling soft, hydrated and I don’t react at all! I leave it to dry for a couple of minutes before you apply make up. It’s lovely stuff. Will definitely buy again and again.
    Didn’t do much for my dry, eczema prone skin. But definitely worth a try given it’s so affordable. Maybe it’ll work for you.
    I bought this product because I've heard such good reviews on The Ordinary products. I was super excited when it arrived, I've followed the instructions and been using it for a month now. Very disappointed because it makes my face feel very sticky instead of hydrated. I also hoped that is would let my makeup sit well but instead after three hours my face is dry and my foundation is not sitting right. Very disappointed. Would not be repurchasing.
    Very good product
    It’s what I was looking for; smooth and soft skin
    Best product ever
    My skin looks amazing and feels so soft. It makes a big difference in my routine. For sure a product to repurchase
    More than ordinary
    Having dry skin this product immediately hydrates and leave skin moisturised. I use it with another million products from the ordinary collection and people remark on how wonderful my skin looks.
    Great product great price
    This really makes a difference in skin appearance, my husband is using it too. Definitely delivers!
    Great for dry skin.
    Love it! Super nice for plumping my skin and giving extra moisture. If you have dry to normal skin, definitely recommending.
    Such a difference
    My skin is so much more full and thriving when I’ve used this! Can’t fault it.
    Hyaluronic Acid
    I'm young (let's just say under 20), and after a few uses, I don't really see much of a difference. Though to be fair, I've used it only about 5 times. It pills on my face if I rub it so I end up having to quite literally, slap it into my skin. It's sticky, and if I touch my face say, 15 minutes after applying, I can still feel it. Take what you will from this review.
    The ordinary
    Loved it
    Absolutely love this product. It feels a bit sticky at first touch. But dries perfectly and it really has saved my skin.
    Will not repurchase
    I'm 54 with normal skin, and normal skin issues for my age too. Before this I was using Matrixyl + HA but I decided to give this one a try. It's too sticky and it doesn't deliver like Matrixyl did. In fact my vertical frown line seems to be reappearing! Back to Matrixyl for me.
    Awesome product
    It’s super light and hydrating! Great value for the price. Fragrance-free and very gentle.
    Everything The ordinary
    Honestly have been amazed by all of the Ordinary products I have purchased, and could not be happier with how much my skin has improved and for such a small dent in the bank!!! Would highly recommend trying anything from the Ordinary as it’s all relatively cheap anyway so if it’s not for you at least you haven’t wasted loads of money.
    Hyaluronic Acid
    I have been using this for a couple of weeks now and my skin definitely looks better. Clear and brighter. Will buy again.
    Great stuff
    This is a great product. Does what it says and doesn’t cost the earth.
    Good for oily face
    When you have an oily face, but it can still get dry, this is what you need. It's lightweight and it doesn't upset my skin.
    Good job
    Its taken me years to perfect my skincare regime as my skin is ridiculously fussy. This solves the issue of having dry skin but with a shiny oily nose and chin. Tinted moisturiser alone is insufficient for the dryness but if I add another moisturiser or serum everything gets shiny and slips off my face in the day. Now I just layer The Ordinary hyaluronic acid under the tinted moisturiser. My face is no longer dry BUT ALSO it doesn't make my nose oily but somehow sucks the tinted moisturiser neatly on to my skin so it lasts all day. Nothing fiddly in the ingredients to make my skin get angry so all is good. I'm on my 5th bottle.
    Great product
    Love this as the first step in my moisturising routine! It absorbs well and my skin feels hydrated right away. A lot of bang for the buck!
    Had really stubborn dry, flaky skin around my nose for years that no amount of exfoliating, moisturising or product would clear but after using this for only a couple of days it was all completely gone. Skin looks plumper and healthier. Amazing if you desperately need hydration but hate heavy moisturisers. I use this and a light moisturiser with spf and I'm good to go.
    Nothing happened
    I used this product for a month before I put on my moisturiser morning and night and I neither saw nor felt any difference in my skin. Bit of a letdown.
    Hair hack!
    It's a great starter product for someone who wants to ascertain if their skin reacts well to hyaluronic acid. I like using this on my hair after a shower. Gives my locks incredible volume, and the ends look less wiry.
    Cheap, cheerful and home use ONLY
    I’ve been using this serum for almost 3 months and I still have so much product left. It’s a great serum, good price, no smell, good quality bottle, but it is so sticky and gooey to use. I found it hard to use with other face creams or serums as they just gathered on my face looking a mess. I was advised to mix it in with my face cream - NONE of my face creams were having it. Great buy but very sticky and I wouldn’t suggest using to prep skin on a big night out. You’ll be there all night trying to wipe it off.
    Like it! Suitable for Eczema-prone Skin
    I recommend this product for young people like myself who have dry, eczema-prone skin. It does not irritate my sensitive skin and does not hurt even when applied directly to eczema. My face feels plumper and softer. However, once it dries, it leaves my face look super shiny yet not oily, like a polished wax figurine! A moisturiser is definitely needed after using this to get rid of the wax effect.
    So far loving it
    Received this product yesterday and I wanted to give it a good amount of time to review but I can see results instantly. I have very dry, dull and sensitive skin this time of year and a patch of psoriasis under my nose which usually reacts to any moisturiser even the natural based ones. But this stuff is fantastic the consistency is sticky but when rubbed into the skin it feels smooth and my skin looks revived and dullness is gone! So far I’m loving it much better than any moisture or facial oil I’ve ever used I really do recommend if you suffer from dry and dull skin even if you have psoriasis as it’s helped cover the redness.
    THE ORDINARY Hyaluronic Acid 2% + B5( 30ml )
    This is the perfect staple serum for any beauty routine especially if you have dry skin. It does what it is supposed to do without the high price tag. I have backups of this kept at all times for when it runs out.
    Easy to apply, a little sticky but once dry it's fine. Sinks in quickly, the only thing I found it pills with is La Roche Posy effaclar duo. Made a nice difference to my skin, smoother, plumper and all my other products seem to go on better.
    I don't get it...
    I really don't know what I'm doing wrong with this but it piles like crazy on me. It's absolutely maddening. I love Hyaluronic Acid, I think it's THE best product for hydration out there but for whatever reason if I put anything at all over the top of this, even if I wait for ages and apply the recommended serum to follow on from it, it comes off in annoying rolls. I'm really disappointed as the price point is unbelievably good. I'd still recommend giving it a go just in case you're a lucky one that can get away with it, it's only £5.90 after all :) Good luck
    Definitely worth buying
    This product is super effective. I use it before moisturiser day and night and my skin is noticeably softer and more hydrated after just a few days. The only downfall is it is sticky, albeit not once applied.
    Love it!
    I started using this around Christmas time and I absolutely love it (so does my husband!!). I usually get dry skin across my cheeks during the winter but since I've started using this my skin is lovely and soft. I have only been using it in the evenings before my moisturiser and haven't needed to add it to my morning routine to see results. I will definitely be buying more!
    It's my new fave thing
    I'm obsessed. It can sometimes pill if I moisturise too quickly afterward but otherwise it sinks in quickly and I can feel a marked difference. It's also perfect to beat the post pool dry skin after I swim! I'll repurchase until I'm dead.
    This is REALLY awesome
    I think I could use that instead of a moisturiser during the warmer months. It's so good, it doesn't break me out, it is neither heavy nor sticky. It also acts as a perfect layer underneath the moisturiser in winter. You don't need to use much in order for it to work. Highly recommend this!
    I can't live without it!
    This is the cheapest and best hyaluronic acid I have ever used. So good for sensitive skin it actually helps my skin from being sensitive. Sometimes areas of my skin can feel sore and tight and flaky this really helps and stops this. I use it night and day and notice a difference in my skin it really plumps it up and gives amazing hydration from within when used before a moisturizer. I have tried a lot of products from the ordinary and this one is by far my favorite. I wish it came in a bigger size though.
    Not the Wonder Product I expected from reviews
    So this is a brilliant price and it is really good for my sensitive skin in the way that I had no reactions. Unfortunately this product didn't work for me. I am not sure if I have extra dry skin but I can't say it left my skin super hydrated throughout the day. I have used it for a month (as all new skincare regimes need a month to settle in) but it hasn't worked for me. One random hack that I found out though is that you can make any of your eye shadows into super lustrous eyeliners using this. Just add hyaluronic acid to the eye shadow and use a eyeliner brush to apply. As it doesn't cause any reactions with your eyes it's brilliant!
    This stuff is brilliant
    I have eczema and this stuff keeps it off my face. Its brilliant, my skin feels plump. I've used up my last bottle and currently waiting on a new one and my skin on my face is awful, tight and itchy. I know I need this to make the eczema go away. It lasted me a good five months. If you have eczema, I would recommend this product.
    Great hydrating serum
    I love this, and I wish it would come in 100 ml, or even larger like the Hada Labo Gokujun Premium. Super hydrating and plumping. Maybe not the most elegant formula out there, but it's absolutely great for the price.
    Mixed feelings
    I love how affordable this is, but I don't like the texture of this serum (I feel it pills sometimes), and it doesn't provide enough moisture for my dehydrated oily skin. If you're broke, try it out.
    Perfect for exactly what I want it for and that only
    Use this ALL the time, almost finished while other ordinary serums purchased at the same time are easily 3/4 full. It’s not the best hyaluronic acid for long-term hydration on deeper layers, but for a quick fix surface smoother it’s a winner. I also really love to slather hyaluronic on my lips and feel like doing that with anything more expensive would be a wee bit wasteful (makes ‘em swell up huge in preparation for a good lippy, or layered with eye cream and then balm to get rid of chapped lips overnight). If you’re chronically dry or dehydrated this won’t really help by itself, I think of it like a primer. Also, as with every Ordinary serum, STICKY.
    The best
    The best hyaluronic acid serum I have ever used. Unbeatable and such an amazing price.
    Price good
    This product is great! It's hydrating and I use it day and night as per the bottle. I've repurchased this already even though still on the first bottle which I've used daily for 2 months and still have 1/5 left. I'm in my 30's and have oily/combi skin so really trying to look after my skin. I'm trying out the rest of the range since it's so affordable for skincare.
    I can't believe how good this little bottle is for the price point. I have sensitive skin and am always nervous to try out new products. I've been using this morning and night for over two weeks under my moisturiser and I am absolutely amazed at how well it works. It leaves my skin feeling plump and soft with a healthy looking glow. I would highly recommend this and will be repurchasing. Can't wait to try out other serums by The Ordinary.
    Holy Grail Product
    I saw this on many influencers social media and thought I would give this a try. My skin is combo-oily and at 20, hormonal spots are real. I was a bit sceptical as to what this could do for me, but I am amazed. This along with an oil free moisturiser is perfect for my skin. I don't get oily anymore and my skin feels hydrated all day long. I use this morning and night and it has changed my skin amazingly, would highly recommend.
    Love it
    My skin has definitely felt a lot plumper after using this for about a month and it has helped to hydrate as well.
    Highly recommended. Skin feels instantly moisturised on application of this product. Can use this morning and evening. I use this first before applying serums and face creams. Would definitely buy again.
    Good product
    This is an amazing product to rid away dehydrated skin. It has caused Malassezia around my mouth but it's fine as dealing with dehydrated skin has been so tough and this B5 acid has surely helped my skin get back to its natural skin type.
    Budget HA but the not the best one!
    It's a good budget hyaluronic acid for those on extremely low budget as well as those with young combination/oily skin, BUT for those older skin the texture has a far too silicone texture & sticky. It doesn't absorb as quickly into the skin compared to other budget serums I have used, so will probably stick to more better formulated serum!
    Not sure if it works
    I have been using it for a month and haven't noticed any difference. Lactic acid 10% + HA feels much more moisturizing.
    Love at the first touch!
    It's the absolute best hydration product: non-greasy touch, looks like water on the skin and disappears in less than 20 seconds which speeds up the daily routine. I apply at night because I like to have a greater hydration at night, the skin wakes up amazing and super hydrated. I have been using it for about 4 months now and I also notice a decrease in fine lines. Super recommend it!
    Not bad
    Its a good alternative to expensive hyaluronic acid serums but it’s not as good because it’s quite sticky. Overall HA is not worth the hype, even the expensive one doesn’t do much for my skin.
    Not sure
    It definitely feels like it has some tightening effect once it drys down after a few minutes but I didn't notice any effect on my skin in the mirror. My skin feels dryer through the day and I usually apply more moisturiser in the afternoon if I'm not wearing makeup. I've also tried mixing it with my moisturiser and that's a little better but overall I don't feel i have any difference to my skin after a month of use. Cheap so try it but I will be looking for something else next time.
    OK but avoid if you break out easily
    At first glance this HA serum seems pretty safe if you're trying to avoid comedogenic ingredients, however is contains 'Ahnfeltia Concinna Extract', which upon further research is the fancy name marine algae, which will break you out if you're prone to clogged pores! Shame as I had high hopes for this product.
    This product is wonderful and I wish I'd found it years ago before the wrinkles really started kicking in. It keeps my skin wonderfully soft and plumper than it was and I wouldn't be without it.
    Good HA serum
    I love it as far as hydration goes. Usually use it on my lips before any balm and after exfoliation. Its texture is very sticky, so if that's something you don't like, then I wouldn't recommend. Overall, good value for money in terms of hydration.
    I love this. this is my holy grail product. Highly recommend it for anyone who needs hydrated, plump skin.
    Hyaluronic Acid
    I really like this product. I have dry skin so it definitely keeps my skin hydrated. I use it as a primer too before make up if I have extra dry skin and it helps with my make up stay put without any dry patches. I use it in the morning and night time. Would definitely order again.
    Great find
    I had plasma eyelid tightening treatment when I received this product and after having been using this for weeks and healed from the treatment, I repurchased this for myself (and my mom and my cousin too). Great price and visible results. I recommend it to be incorporated in everyone’s skincare regime.
    I have dry and dehydrated skin, and (used to) have problems with acne. This bad boy is a great hydrator and I absolutely love it. It goes amazingly with any other product and I use it in both the AM and the PM. Now on my third bottle! Would recommend to anyone.
    I love it: the texture, the smell (or lack of) and moisturising factor. I've been using for a few weeks and I already feel that my skin is smoother and brighter. For the price, it's amazing!!
    Nice serum
    I've been ordering this on repeat for quite a while as I (and my Mum) just love it - such good quality product at an amazing price. Easy to apply and leaves our skin feeling lovely and firm.
    Really nice
    Not heavy and very hydrating :) It gives a glow and when used on slightly damp skin, it really delivers a punch of hydration.
    I love this product! I use one drop and it covers my entire face. I pat it into my skin after cleansing and toning my face and before moisturising. It works a dream. I’ve had it for a month now and there’s still loads left! Definitely repurchasing once ive used it up.
    Very Plumping
    Moisturised like a dream. Skin feels really plumped. Have to put it on very quick as becomes tacky otherwise. I had some peeling but changed the order of putting it on. Sunscreen before the moisturiser or barrier cream did the trick.
    Great product
    Love the product. Really great serum. Does wonders for my skin.
    Good stuff and affordable too
    Used it for about 2 month now and I'm very happy with this formula. Moisturises my skin throughout the day. No more dry skin feeling after a long day. Plus I can apply my makeup and it won't crease under eyes or highlight my pores. After applying Hyaluronic Acid 2% + B5 I use my normal moisturiser let it dry for 10-15mins. Gently rub off any excess moisture with clean hands on my face and then apply makeup.
    Love my Ordinary skin care products.
    Love it!
    Works well for my sensitive skin.
    Worth the hype
    I've been using it with a water-based moisturizer and i'm loving my skin..
    Bien ***Good***
    Bien sin más. Llevo usándolo más de 15 días y la piel ha mejorado ligeramente pero no lo veo una bomba de hidratación ***Good, you don't need to use much. I have been using it for more than 15 days and the skin has improved slightly but I do not see it as a hydrating product.***
    It works well
    I love this hyaluronic acid. It does what it says and leaves my skin hydrated and soft. I love The Ordinary and will be purchasing more of the line soon!
    Great product
    I was dubious as my skin is problematic but understood I needed to properly hydrate my dehydrated skin instead of just surface creams. This product really does the job, my skin is plumper, less angry and sore looking - sadly not much less oily but it’s a start!
    Love it!
    Really great at locking the hydration in and giving my skin a healthy glow!
    Super affordable
    Love this product. My skin feels very hydrated and smooth after using it. Plus it’s not too expensive. I would definitely recommend this!
    I bought this not expecting it to much due to being 51. This product is literally amazing, my skin looks plumper and clearer and whenever I put it on my skin and I get comments that I'm glowing. Will be a permanent item for life now.
    This serum really hydrates my skin, i’m on my fifth bottle! Love this stuff!
    The best
    I’ve always suffered from dry, excma prone skin- and since using this day and night I have noticed a huge difference. Dry patches have gone so make up sits much smoother and my skin feels much more hydrated. Totally obsessed.
    So far so good!
    Okay, so this product is quite affordable, so I'm not complaining at all as I think they skip the "feel good" experience to cut costs, but I have to say, that this product is quite goopy and is sticky when you first apply it on the face. But when you go beyond that in a few seconds, it dries and has a smooth texture. I use 2 drops and that seems to be enough for my face, and I think it's better not to use too much, as it can have a thick texture and is easy to put on too much. Having used Skinceuticals HA before, they provide the "feel good" aspects, but then again, you are paying for that :) As for hydration, I think it is hydrating my skin, but I use cream on top of this so it's hard to tell at the moment, and I need to use it longer to see the results. But so far so good, I'm happy with it :)
    I love it but...
    I've never tried a HA acid before, however, it goes onto my skin smoothly, it feels nice and my skin is still clear and smooth. Does not clog my pores or make "pills" on your face. Just rub it in, leave it for a sec and then moisturise on top! I did also buy a new face cream and having been using the two (it is drops of youth from the body shop) so I can't comment on the HA as a solo product. However, I'll definitely be buying it again. Just make sure you don't use too much. It makes my skin feel and look nice and that's exactly what you want. Plus for the price, definitely worth trying, even if it isn't for you. I'm sure a friend or family member would take it off your hands if you didn't like it. I'd recommend.
    Wish I found it sooner...
    I went for a facial recently with the sole aim of getting advice on my dry edges of my nose and cracks of my mouth and the lady said hydrochloric acid. ‘It’s like a drink of water for your face..’ It is!!! Took a couple of weeks applying it 2 x per day but my make up didn’t stay on those places for over a year I’ve had the issue - one thing, it doesn’t FEEL hydrating, feels a little gluey, but obviously you add your own moisturiser after for that.
    I bought this along with a handful of the other basic The Ordinary products and by gosh! After only a week my skin looked a treat. No more dead skin and it actually looked GLOWING, it was fantastic. Shame they don't sell it in larger sizes so it'll last me even longer. A fantastic product for a great bargain - I originally planned on buying the Glossier serum bundle but those are soooo overpriced and probably don't work anywhere near as well as this. Heaven in a bottle.
    Nothing Amazing
    I'm giving it a three because it didn't cause any bad reactions/side-effects but it didn't do anything overly amazing for my skin either. Both me and my sister, have found that this product has a tendency to pill when used in a routine; you can't layer this over/under other products in a routine, without it coming off in bits (that's what pilling is for anyone who didn't know). So is it something you need? No, not really but have a go yourself and see what you think, it has worked well for so many people so it might work for you too!
    I had never used this before but I'd read all about it and also read the reviews. I can honestly say that I'm a convert. I'm hooked on it , this is by far the best oil/ serum I've used. My skin has never looked so good , my pores are less visible, my crows feet seem to look less noticeable so I'm a very happy customer. The price of The Ordinary Hyaluronic Acid 2% is such a bargain plus I love their vitamin C face cream as well.
    Amazing, a miracle.
    I have large pores so I was attracted to this product and after reading the reviews I decided to give it a try. I’m so glad I did! My routine before was cleanse, tone, moisturise, prime, foundation then finishing powder but almost immediately the pores would be back! After introducing this to my routine between the toner and moisturiser stage I can say no more visible pores! I shall be ordering this again!
    It’s good 5 from 10
    It’s start with make your skin very soft but after 1 month it’s like not help it’s too much, but I do apply with another product not too bad, but not amazing!
    Great, immediate effect, recommend.
    Damn good!
    I don't know what it is, but T.O. products are so amazing. I've tried many (EGCG - Buffet - Glycolic Toner - Retinol 0,5 in squalane - Niacinamide - Ascorbyl Tetraisopalmitate Vit.F - Moisturizing Cream - Mineral UV filter Spf 30...) and none of them upset me! This serum in particular gives deep hydration to my skin which is no more dull. And for this price... I'm in love!
    Immediate firming
    I haven’t got deep wrinkles, just smaller ones yet. I like the product as I can feel an immediate firming effect. Dries quickly, easy to use. I have only used it on my face. It really gives you a smooth effect and your skin feels hydrated after use. Will buy it again.
    Caused a breakout
    I bought this reading the great reviews unfortunately it did not live up to the hype, I have dry skin and used a couple of drops day and night and this made me breakout in spots. The item is cheap enough to experiment with so I don't feel like I wasted money, but it was a huge disappointment
    Brilliant product
    Brilliant results, I have super sensitive skin and this serum used twice a day gives me a hydrated and moisturised result. I am used to using high end products but not any more! Thank you The Ordinary.
    Ordinarily Good
    Really good products that work at a down to earth price
    Parched skin saviour
    My dry skin drinks it up. Since it was ordered to Dubai, it did take time to reach. But the wait was worth it. The air and water still makes my skin dry, but this serum is my only way to remain hydrated. I follow it with a oily serum or moisturizer. And with the affordable price range, repurchasing it will be a no-brainer.
    One of the best acids
    Every day I can see my pores getting smaller and feel my skin getting softer.
    ..as every single The Ordinary products are!
    Good product.
    When I first used this I had problems with the product piling on my face when applied under other products. Now I use a lot less and no longer get this issue (Need to use the tiniest amount) This has helped my dehydrated skin.
    Worth the money
    This is the first time I’ve purchased a serum. A couple of drops leave the skin feeling hydrated and moisturised, great before applying any creams/ointments. Would definitely recommend & worth every penny
    Really Good!
    Really good product and amazing value for money!
    I am 46 with combination skin and this serum works perfectly on all zones. A few drops is all you need and it absorbs quickly. Great for those of us who don’t like heavy creams under our primer and foundation.
    This stuff is amazing! I'm a complete sucker for potions so make my skin softer/tighter/brighter/younger etc etc so much so my bathroom resembles a beauty store. I stumbled across this little bottle of magic and thought it was cheap so why not. It works better than ANYTHING I have ever tried before! I mean really! the wrinkles on my forehead are smoother and my skin is tighter and softer. Absolutely well worth the money, give it a go!
    I love this serum, I’ve been using it for about 7 months now and my skin is smoother, plumper and more hydrated. Now that it’s the summer I’m only using it once a day as I feel I don’t need it as much but in the winter I use it twice a day before my moisturiser and it keeps my skin well hydrated. For reference, I’m in my early 30s with normal/combination skin
    Love this stuff
    I don't know why but this serum works on me better than 65$ Peter Thomas Roth hyaluronic serum. Recommend to try.
    Absolutely nothing
    Maybe it works on 20 yo girls with no skin problems. But on my 30 yo dehydrated skin I didn’t notice a thing after half a bottle. It stayed dehydrated. Not worth the buy.
    Sadly I wasn't impressed with this serum, even though the price is great I found it pilled really easily and didn't layer well. Also for my oily/combo skin it was too sticky and greasy for my skin. I would recommend it more to the super dry types where it may work better. I also noticed 0 results from using this.
    Amazing stuff
    I'm probably on my 5th bottle of this. Amazing stuff, super easy to blend into the skin and dries instantly, you don't need to use a lot at all. Makes my skin look and feel smooth and plump. Will forever repurchase!
    Good basic hydrator
    It's a good starter for discovering HA but I find it pills on the skin. Prefer Hylamide's version & MMHC.
    Long lasting hydration
    I love this product. I have dry skin with pigmentation. I like the slight stickiness of this product, which absorbs immediately upon application. I use it in the morning and wait a couple of minutes after applying before putting on foundation and have not had any problems with pilling. I use 4 other Ordinary products (for approx 3 months), and I must say at the age of 50, (and after spending a small fortune on skincare throughout my life) that thanks to The Ordinary and Demarolling for better product absorption, my skin looks fantastic and has never looked better. ❤️
    Good product
    This product so far is good for my skin. My skin is way better now and no longer dry. However, it would be perfect if the texture of the products isn't as sticky. If I'm not mistaken they've come out with a better product which has the same purposes. It's called marine something if I'm not mistaken.
    Really good product
    Better to use it in a humid place like in the bathroom. Also as soon as it's soaked into the skin, need to apply moisturizer or other serum. Very good product for the price.
    This is great!
    Makes my skin very soft and very moisturized. I like that it doesn't have a scent at all. I have to agree with the other reviewers that it is indeed a very sticky product, but once you layer it with your moisturizer that feeling goes away. Will definitely repurchase this!
    The Ordinary - Hyaluronic Acid 2% + B5
    Has a sticky consistency and really didn’t notice any difference whilst using this.
    Worked for me
    It is so easy to use and absorbs quickly to the skin. I used this after cleansing and toning my face following with THE ORDINARY COLD PRESSED ARGAN OIL. This combo is amazing for dehydrated and dry skin. My skin is not dry anymore, love it will repurchase it.
    This is the perfect staple serum for any beauty routine especially if you have dry skin. It does what it is supposed to do without the high price tag. I have backups of this kept at all times for when it runs out.
    Not impressed
    Has a sticky consistency and really didn’t notice any difference whilst using this. I have been using this for well over two months and honestly, do not see what is so good about it. I don’t mind though because the price is good. However, I will not be repurchasing in future.
    Good but sticky
    This is just such a good hydrating product, but I find it difficult to apply a lot of the time as I find it so sticky. I worry that lots get wasted on my fingers which I rub into my hands, but I'd rather have this on my face! I didn't repurchase as I wanted to try a different one from another brand, but due to the price, I would get on with the stickiness and repurchase!
    Not happy
    This product made my skin worse overtime so I stopped using it. It gave me small bumps in my skin and dried my skin out. Would not recommend this product for oily/combination skin.
    Great but sticky
    This product is extremely hydrating and sinks into the skin very quickly so that you can barely feel any product but you can notice the hydration. I like to use this after I cleanse and before moisturiser. It can also be worn underneath makeup. However, the product is extremely sticky and appears almost elastic. I did not expect this, and you can get more pricey hyaluronic acids which are more water-like in texture. I am also not a fan of the smell, but it's not too overpowering. Having said this, I do think that it is a great value product for the really good result you get, and definitely worth buying if you want a hyaluronic acid but don't want to spend loads.
    Wasn’t worth the hype for me
    I was so excited for this product but I found that after applying it in my evening skincare routine, my skin really looked no different in the morning in terms of hydration to how it normally did. I also found that after a few days the only thing that changed in my skin was that I had small bumps and uneven skin texture in certain parts of my face. I then stopped using the product and it went away, so I have to say that overall it really didn’t do any good.
    Not sure what to think
    The product feels good on my skin but isn't the miracle product I was expecting from reading these reviews. I expected more long-lasting moisture. But for the price, I will be repurchasing and I will continue using.
    My Love
    I have been using this for about 3 months now. This makes my face hydrated and I love my healthy skin now.
    Not bad
    Although this serum did not perform miracles to my skin, it did no harm it either. It's quite hydrating, not sticky and perhaps it's better for a dryer skin types
    Keeps my hands hydrated
    I put this under my handcream as I don't need the hydration on my face but get dry hands that get eczema. I have a prescription steroid cream but if I had this under my handcream the eczema disappears within a week. I have used a bottle in the last month.
    Best product ever
    I absolutely love this! I am on my second bottle now and recommend this to everyone I know! helps hydrate my oily/combo skin without looking greasy. On application, you can really feel the product absorbing into your skin rather than sitting on top of the skin so you know you are getting the best use out of the product.
    A wonder in a bottle
    Love this product! My skin has been loving it since I tried it 2 weeks ago. My face feels supple and not dry at all.
    Already a staple
    I have only used this product for a short period of time, but it has already become a staple of mine. It's great for my sensitive dry skin, and i can really feel a difference. I feel that it is a product that has been missing on the market, and I love that it's so affordable.
    Hylalurnic acid
    I've been using this product for several months now and find it amazing, it certainly does what it says on the can. Wouldn't be without it. I am so delighted with all the Ordinary products I have purchased. I still can't get over the cost. I used to spend a fortune on high end products that didn't work out as well for me. Thanks guys.
    Good product
    This is a good product that I have used.
    Exactly As Described
    I read about this product and have now used it for a month and I am very impressed with the results. Firmer skin, reduced wrinkles and under eye bags. Thoroughly recommended.
    Not long lasting hydration
    This is a HA serum I think is just ok for me. I would totally recommend using it instead of not using any hydrating serum at all. But the effect of this one is not as long lasting as other HA serums I have used on me, already at lunchtime I can feel surface driness again, with other HA serums it often feels hydrated longer into the day (Jordan Samuel, Dr Dennis Gross, Bobbi Brown Remedies to mention a few).
