    Sunday Riley - C.E.O. 15% Vitamin C Brightening Serum

    Sunday Riley C.E.O. 15% Vitamin C Brightening Serum Reviews

    Get the glow?
    Keep repurchasing this as it gives me such a lovely glow in the a.m. Hadn't got on with Vitamin C on a couple of occasions, (easily irritated and a bit sensitive) but I think I've finally found the one!
    Will not recommend
    I have used this product for my hiperpigmentation and this is the fifth week but it made my hiperpigmentation worse. Am very disappointed. It didn't work at all.
    A winner!
    I love this serum, it really did bring a 'glow' to my skin (received comments from friends and family), however for the price it didn't seem to last very long? I had to use around 3 pumps for my face and neck, so the bottle only lasted around a month. Perhaps it is due to my dry skin not absorbing it properly but I would have hoped it would do me a little longer.
    Works so well!!
    Since using this my skin is in the best condition it has been for a while, helped to reduce pigmentation from acne and brighten when it’s looking a bit dull I love it!! Definitely worth the price tag!
    Love it!!!
    I have uneven skin tone due to acne scars, and this product has saved it by giving a lovely healthy GLOW! I can literally see the glow on my skin. I will keep repurchasing. Also plus point for the luxury, beautiful packaging , and super quick delivery service from Cult. Very very happy with the whole thing
    Glowy Goddess
    During summer my skin tone becomes uneven and starts to look dull. I was reluctant to buy due to the price but I read other reviews for this that said it was amazing so I just had to try it! I have been using this for a few weeks now and have I noticed it has evened out my skin tone and made me glowy yassss!!!!! The only thing I’m not overly keen on is the scent but obviously that’s my personal preference. Still recommend it though sistaaas
    Extraordinary
    This is the only vitamin C serum that really works for me and my freckles! My face is so much brighter now. Nothing else has the same effect
    Orange Blossoms
    Just fabulous! Lovely orange smell to it (which fades after a few minutes) consistency is thick but not sticky and I wear the CEO Glow Oil underneath (just a couple of drops) and it works wonderfully together. I give myself time in the morning to let the products soak in before applying my moisturiser and sun screen. I have oily skin and you’d think this would be far too much but it’s working for me so far - I do use a mattifying sun screen (Soap & Glory SPF 50 or Supergoop SPF 30 for anyone whose interested, the former is scented). As I’ve only been using this Serum since 30th April I’ve held back on the 5th star and want to wait until the 12th week mark to assess change to my hyperpigmentation and acne scars.
    Great product
    Light fragrance. Easily absorbed. Works well.
    The Real C.E.O
    This serum has brought life back into my skin! I tend to find Vitamin C serums a little sticky but this gives me a smooth silky texture each time I apply it. This has also helped calm down any redness from previous breakouts and smells like fresh oranges.
    4/5
    I have used this for about 3 weeks and love it. Absorbs well and iv definitely seen a difference with the plumpness of my skin and hydration. Lost a star for the price, but then I'd rather spend abit more and feel the benefits then abit less and feel non! I use this with the Sunday Riley retanoil serum too
    CEO GLOW
    I’ve added this into my routine along with the oil in the morning. I have been doing this for a month now. A small bit goes a long way and I can really see a difference. My skin looks healthy and the instant glow is addictive.
    Fab
    Love this serum :)
    Very pleasant and instant-result product
    I usually break out from Vitamin-C, so I was very pleased to find this one didn't ! I actually really enjoy the fresh orange smell and it instantly makes the skin more plum and brighter. On my 2nd bottle and will def repurchase.
    Amazing serum
    Love the subtle, pleasant citrus aroma, although I like my products fragrance-free... It absorbs really fast and plumps the skin very well! Usually my skin breaks out after I start using new vitamin C serum, but not in this case!
    best vitamin C
    I tried a few vitamin C's, but my skin reacted best to this. I have very sensitive dehydrated skin, but after just a couple of weeks my skin was glowing and was brighter. This is the only Vitamin C I could use with an AHA without it causing irritation. Currently using biossance, but will go back to this one as I love it.
    It works!!!
    This really brightens and hydrated my skin! It does work but it’s pricey so your choice!! ( My skin is A very light olive coloured)
    Amazing
    Amazing!! Can see massive difference in skin in 2 weeks
    I’m a beginner for vit c and it works really well for me!
    I’ve been using this for 2 weeks. I really love the texture, it absorbs fast into my skin. I used this right after my cleanser, my face stings a bit at first but after then I’m okay with it. It doesn’t cause any breakout for me and my skin loves it very much!
    Can’t be without this!
    This is the only skincare product I have ever used where I can see an immediate difference. It’s so light, a joy to use but gives a gorgeous glow and has really helped my pigmentation. It’s quite pricey so I have tried cheaper alternatives but nothing has compared! I will never be without this in my stash and is well worth the money.
    Great product
    I use it every day only in the mornings and it is amazing.
    Amazing!
    The most amazing vitamin C that I've tried, actually the best. This serum is lightweight, sinks in nicely and improves the look of my scarring. I haven't noticed much difference in my texture but I definitely will still repurchase it even it's pricey for me. Hey, but never mind! The pump bottle is awesome and allows you to control the amount of serum you use easily. Yup, this serum worth your money :) .
    Third time repurchasing this
    Worked really well for my face, significantly improved texture and worked well in reducing scars or marks left from acne. It also worked wonders reducing hyper-pigmentation. I have incredibly sensitive, combination skin.
    Love it!
    What more can I say other than I love it? It's lightweight, sinks in nicely leaving my skin bright and smooth. One pump is fine for the whole face so even if is not the cheapest, it'll last you ages. Worth the try, but beware: you'll fall with it!
    Good
    I've been using this Vit C serum for over a month and I'm quite satisfied with it. It leaves a slightly sticky feeling after application but after I moisturise it's gone and it doesn't bother me. However, I'm not quite sure if it actually does improve my skin or if it's actually brightening. I have quite oily, acne prone skin with large pores and luckily, it hasn't broken me out. After I finish the bottle, I will probably try the CE Ferulic from Skin Ceuticals, just to see a bigger difference.
    Love it
    It's not my first vitamin c I use. I really love it. It's not streaky, it doesn't smell bad and the formula is hydrating and creamy, not oily and very nourshirng.. my only complaint is the price and I actually ran out really quickly it only lasts a month and a half, and actually a bottle lasts about two to three months, it was really confusing for me. I'm not going to buy it unless there is a real sale on Sunday Riley, I usually use vitamin c from klairs and I'm in love with it but I had to try this one.
    Good one.
    I love this one, I use is everyday.
    Great
    I love Sunday Riley x
    Better than Drunk Elephant
    It’s more stable than DE. And much more moisturising. And smells better too.
    The best
    Very moisturizing serum, it’s everything I want from a serum.
    Moisturising and brightening
    I use this product every morning before moisturiser. It absorbs well and is really hydrating, and I love the orange scent. If I use more than one pump I feel my skin can be ever so slightly tacky, so I am careful with how much I use. However, my skin is really glowing, and makeup sits nicely on top. I have been struggling with dryness a lot less, and I think this is part of that. Will definitely repurchase.
    Quite nice
    I have oily and sensitive skin. This does a good job of brightening and moisturizing the skin. I also feel like this is quite thick for a serum and can be used as a moisturizer for those who can't use heavy products on the skin.
    Sticky
    I've been using this for more than 3 weeks now and have yet to see any improvement on my skin. I have combo skin and this sort of is a sticky concoction that needs a lot of powder to make it stay less shiny. Overall for the price i feel there isn't much this is doing for me. I will continue using it since I've payed a lot for it.
    Beautiful Consistency
    After trying so many vitamin c serums, I think this is the best one so far! It has a cream consistency without being too sticky and smelly. Absorbs quickly into the skin and gives a really nice glow!
    Faaaaave!
    I’ve been using this for about two months now.. My skin is much brighter and has given me more of a youthful glow. Would highly recommend!
    Glowing game changer
    I absolutely will not be without this gorgeous serum. Worth every penny - and I’ve tried a fair few out before! The glow lasts, so much so many friends have noticed, four of them have purchased since and all four love it too.
    It works!
    I've been using this for just over a month and I have noticed the difference. My skin looks brighter and more youthful! I've used it a couple of times after sunburns from the beach and I can't get over how fast the redness calms, how soothed my skin feels. The only problem is the greasy looking residue, other than that amazing product
    Best Vitamin C around!
    I didn’t think I could see such result in such short period of time. skin is BRIGHTER and HEALTHIER after only a few days. LOVE IT!
    Who knew?
    I’m always reluctant to talk about miraculous results, but this in a few short weeks has been nothing but. Look, can’t say for sure, but I bought it for anti-ageing, yet my hard to shift brown spots have gone waaaay down.
    Excellent product
    I bought this product after receiving a sample and was so impressed with it . It smells divine and leaves my skin soft smooth and with a lovely healthy glow . I have recommended to friends and family and will buy again
    Great vitamin c serum!
    After using the trial version of this serum, I decided to buy the full-size version. Great serum, evens the skin tone, reduces redness, and gives an amazing glow. I have mild rosacea and this serum is not harsh on my skin.
    Great!
    Perfect vitamin c serum!
    Absolutely awesome
    I love this product. It’s absolutely amazing.
    Lovely serum
    I’ve been using this serum for a few years and I love it. I’ve come very close to changing it up and trying the skinceuticals vit C that everyone raves about but I just can’t bring myself to let this one go. It’s thicker than your average serum (like a lotion) and If you have oily skin you probably wouldn’t even need a moisturiser on top. I just use spf after. I really notice a difference in my skin when I stop using it. I have sensitive / combination / acne prone skin and this doesn’t break me out. Leaves a nice glow and smells lovely too.
    Fab
    Love this serum :)
    Didn’t work as expected
    The old formulation was good and I did notice a considerable difference when I used that. I picked up the new packaging a couple of months ago and it feels too sticky and doesn’t give the results it used to.
    Love this!
    I've wanted to try this for a good while but the price put me off and I was also worried it might cause me to breakout (I am prone to spots and oily skin). Well it hasn't and I love it. In the past I have used more watery vitamin C serums and I much prefer the consistency of this. It soaks in well and sits nicely under my moisturiser and tinted moisturiser. I have noticed a definite improvement in skin brightness and overall my skin looks generally healthier and not so dull! Will get this again, hopefully in a sale at some point!
    Nice product, not seen a marked difference though...
    Lovely scent and consistency and I like SR products in general, but I haven’t been blow away by this....
    Fun
    Really like putting it on, smells like citrus which I can live with and is also pretty moisturizing. Didn't notice a difference dealing with hyperpigmentation, which is my main concern, Been using it for about a month now... But still, really love to have it and hoping it might work in the longer run.. maybe?
    Serum upset(
    Serum with a pleasant aroma. Incredible packaging with a dispenser. However, I could not use it - on my skin, the serum is coated with a film and is not absorbed, I feel the greenhouse effect on the skin. I really hoped for a positive effect, but I could not use it. It is a pity that I did not fit, as the brand is very worthy.
    BROKE ME OUT!
    This broke me out immediately! I did my regular skin routine and put this product onto my face... 5 min in and it was kinda burning and itching a little, so I decided to wash my face and did my routine all over again, but without this awful product, and instantly I had a new bump that I literally didn't have before! It hurts and it's inflamed! Awful Awful Awful!
    I love it
    It makes my skin so bright and reflective in the morning.
    Amazing
    My skin radiates and I barely need to put on highlighter. Love the texture, absorbs quickly, smells nice and easy to layer, will definitely repurchase.
    Sunday Riley is amazing
    I have most of the Sunday Riley line and I have to say that I use this and the face cream the most. To be honest, I toss up between this and the DE C-Firma depending on how my face feels in the morning. I reach for this one when I need the extra moisture. It smells yummy and I feel like I’m missing something when I don’t use my vitamin C serums before moisturizing.
    Brightening for real
    I've just finished a travel size of this serum and I can tell the difference on my face after using it. It is a lightweight, citrus-y scented emulsion that sinks into the skin leaving it naturally bright and glowing. You don't even need a highlighter. You can confidentially apply your SPFs, creams or makeup on top - doesn't peel off and the hydration lasts all day long. I know it isn't cheap, but the pump gives you the right amount for the whole face so it lasts quite a while. Worth the money for sure!
    Will buy it again and again
    I don't know what is in this but each time I use it, my skin feels good all day. This serum transforms my skin to look healthy, glowing and hydrated. Bought twice will repurchase again.
    2nd Purchase
    Love the texture and the subtle scent. It’s quite moisturising. Where I live it’s hot & humid all the time and sometimes I don’t need moisturiser. The vitamin C is sufficient. I just top it up with sunscreen and I’m good to go!
    Amazing.
    Oh my god this thing seriously brightens without drying your skin out. It just gives you that inner glow instantly without getting sticky. It didn't irritate my skin at all. I noticed a really brighter complexion plus fading of sun spots just after using it for 3 weeks. The best part is you just need a small amount and it smells amazing as well. Definitely a staple product!
    Excellent!
    I have very sensitive skin and my cheeks are especially problematic. I have always had problems with vitamin C and my skin never excepted it. I took a risk and bought this serum because I was desperate for a vit C product that wouldn't irritate my skin - they are just so good for your skin; it's a shame not to use it. This stuff is amazing! It does exactly what it says in the description PLUS it doesn't irritate. Get it if you can. It's worth the money
    CEO of all vitamin c’s
    Seriously brightens. The best vitamin c on the market. Great orange smell and not too sticky and much nicer/better than drunk elephant which is way too sticky for my liking. Love it.
    Nice and bright!
    I’ve tried loads of serums to help with melasma/ hyperpigmentation. This is the first one I’ve seen a visible result from. I have a large pigmentation spot that has visibly cleared. My skin is oily and can get congested but this serum has not blocked it up at all. I also love the fresh fragrance
    Phenomenal
    Best product for dull skin, I immediately saw the difference, never knew this product would help pigmentation so much, love it.
    Love it!!
    I love it, it clears and smooths the skin in a short time, the first time in my life that I can see fast result like this I am going to buy it again and again!
    Very moisturizing Vitamin C serum
    I am not usually the one to favour Vitamin C derivatives but oh boy is this nice! I like that as the Tetrahexyldecyl Ascorbate is a derivative form after all and would need conversion into L-ascorbic acid later, it is the second ingredient in the product (unlike a lot of other so-called Vitamin C products on the market that might use some SAP MAP or AT in the fifth ingredient) and it is good that Sunday Riley also tells you the percentage (15%) to stop you from guessing. Squalane is the third ingredient, which probably explains why it is so moisturizing. I am also surprised that despite the beeswax, it does not feel sticky at all, and I use quite a large amount for my dry skin (at least two pumps) in the AM right before my moisturizer. Texture wise, it is a bit thick (similar to Good Genes but less slimy), but it absorbs quite quickly on my skin as if it is a moisturizer, it is super lovely to put on the face (and the orange scent does not hurt either). Unfortunately I can not tell you about the brightening effects, as I do use Vitamin C serums all year round, and my skin is generally in good condition. I can however tell that during the first month of using this serum my skin always looked luminous with makeup on and never once it felt dry. As I use this serum in the AM, I think it definitely has helped and perhaps has also improved my skin to some degree. But since I use a big amount of serums usually, I always find myself finishing 30ml bottles within a month, including this one, therefore, I should have purchased more bottles and continued using it if I really wanted to detect the effect of exactly this product. The only con is probably the price is a bit steep for every month, but I will definitely repurchase it.
