    Sunday Riley - A+ High-Dose Retinoid Serum

    Sunday Riley A+ High-Dose Retinoid Serum Reviews

    A+ High-Dose Retinoid Serum
    Visible improvement on aging skin.
    Amazing.
    I have tried four other retinoid serums and this is by far the strongest and most effective over the counter serum I have found. Be certain to work your way up to this one. It packs a punch, but my skin has never looked better!
    Good
    Tender.
    Disapointing
    Did absolutely nothing, not for acne, not for blackheads, not for wrinkles, not for skin texture. Nothing!
    Great
    This is really nice, feels nice on the face and doesn’t overly smell of anything.
    Love this
    I’ve used this for around a month now, it’s left my skin feeling so brightened and smooth. It’s now a must have for me
    Change nothing!
    This is my 3r retinol product, the 1st one is Peter Thomas Roth, then I switched to The ordinary 5% because of all the positive reivews and the same goes for this one. I do not have any reaction with retinol but I found out that it doens't help anything on my texture as well as premature wrinkles on my forehead though my skin is always considered quite flawless.Having just finished the bottle after 3 months of using, I was so disappointed to see nothing change on my face because I had been highly expected this one. Having just bought Medik 8 retinal 10 and hope it would have some effect, otherwise, I have to find for alternative brands :(
    Amazing product
    This product changed my skin! Love the texture and doesn't leave me with dry irritated skin. It did fade my acne scars pretty fast too and overall improved it to a point that i can leave the house with no make up on. So far i have been using it for about 3 months and will definitely repurchase.
    Disappointed
    I’d read such positive things, and read the warnings about building up to using it often, which I needed as I have sensitive skin. I needn’t have worried. My skin felt very soft after using, but I have not noticed any other differences. No sensitivity at all, really mild in fact.
    So far so good
    I can't tell for absolute definite but I think my skin has improved with use. I've been using it about a month or two so far. I'll definitely purchase again, though, if I get amazing results.
    Amazing.
    This has completely changed my skin, reduced outbreaks skin looks healthier. Amazing.
    Retinol
    I have used this for 3 weeks and really happy with the results so far. Skin texture has improved, light wrinkles lines have decreased and helping reduce my acne scars. Would recommend this retinol over of hers I have used such as the ordinary and allies of skin
    My favorite retinol serum
    I love Sunday Riley products, I started with Luna Night oil, but now i am addicted to A+ Retinol serum. I am on my third bottle. I do use it with CEO oil at night. I have sensitive skin and this works great for me, as my skin can not tolerate other retinol products.
    Still great
    Switched over from vivier 1% to this, since all reviews I read stated this was one of the most powerful over the counter retinol creams. However I saw no drastic change from my other 1 percent retinol, keeping in mind that my skin is way better off with this than it is without (texture, blemishes, glow) but again its not a miracle worker alone.
    X
    At twenty I had started to have slight wrinkles on my forehead this has got rid of them my forehead looks clear however I bought it for acne scars it’s slightly slightly improved one side of the light scars but not touched the worst of it so it does work but not a miracle product had over pigment creams that have worked better but amazing for anti aging
    Retinol
    I have been using this for a month now and have found a big difference with how my skin looks and feels. I use this every night and in the morning I use the UFO and JUNO Sunday Riley products. 3 Things you must have in your skincare routine- retinol, Vitamin C and SPF!
    Beautiful Retinol
    I have been using various retinols for the past 5 years now to help my acne, and more recently scarring now I have got this under control. There is absolutely no downtime with this on my skin, I am using it two days on and two days off and have been using this just over a month now and starting to see the difference in my skin. It's so soft, really glowy and I even had a comment on how great my texture was recently during a facial! A truly beautiful Retinol that hasn't caused any irritation and I'm already seeing results...I can't wait to see the change even more over the next few months!
    My Skin Savior ♥️ Best Retinol Ever exist
    I have super sensitive combination skin and easy to have redness and blemish with most type of serum but not this one
    Very good
    Very good indeed. Is gentle to my sensitive skin and very effective at the same time.
    Amazing
    Completely changed my complexion for the better. Be careful not to overuse when you first start using it and would suggest using a good oil after to restore moisture but honestly so good
    Pricey, but lush
    Having used Retinol products for a while and, not having noticed a discernable difference despite rave reviews, I decided it was time for drastic action. Upping from 2% Retinol to something as potent as this can result in a pizza face. Thankfully, despite my sensitive skin, there was little protestation. The results are gorgeous. My skin is softer than it has been for years, perhaps also thanks to properly exfoliating more regularly. And whilst my wrinkles and fine lines are still very evident, at least my face no longer has the texture of unpolished concrete. Thank you. I will certainly re-purchase.
    Amazing - and I'm usually a sceptic!!
    Like other reviewers have said, this product has actually cleared up my skin enough for me to feel comfortable without foundation... for the first time in YEARS. No flaking or peeling for me at all.
    SUPER STRONG
    I have used acids before and retinoid too and so many different products that are strong, but this one is REALLY strong - so I have been using it every alternative day and being quite cautious, remembering to moisturise well as the skin peels off a lot which makes me think that it is working but I haven't seen any improvement! Super strong, yet to see the effects though! I have been using it for 4 weeks now (thrice a week). I am hopeful that I will be able to build it up in the next few weeks to see better results.
    Disppointing
    Sunday Riley is my all time favorite brand. Unfortunately with cycle and hormone change came some unwanted acne, not a lot, but enough that I need to change my routine. Obviously I looked into the Sunday Riley lines to fix my new issue, and was met with some very disappointing results. After three weeks of trial, I noticed the following: 1) ODOR: the scent was awful, perhaps even rancid, and *maybe* I received a bad batch (which would make this review more understandable). But I doubt that's the issue, SR has very high standards of quality, I doubt Cult would have sent a rouge serum. My make up brushes suffered from the odor as well, it left a bad scent that needed to be washed after every use, instead of every week! 2) SKIN: the serum very obviously made my skin more oily, and I tried alternating between morning and night to see where the issue really lied. The serum was the clear culprit. Oily skin = acne. The issue, instead of subsiding, became worse. 3) COST: I would pay full price for any SR product, but this one, for the fact that it doesn't work at all, is over the top. I resulted in using Caudalie's serum, which is less than half the cost, and works for acne on older skin. Thank you for reading my review. Have a nice day. TT
    Genius
    Its acne and blackhead clearing, it brightens, fights aging, is gentle... It’s not greasy, sticky or heavy. One of the best products I’ve ever purchased. I love a lot of Sunday Riley products, they really work with my skin which is dry/combo/oily/acne prone/sensitive... (like a whole bag of issues) but seriously this is worth every single penny and it works great with the CEO oil.
    Sunday Riley high dose retinoid
    No irritation at all and soaked in quickly. Visible results after only a few weeks and it lasts ages so it's worth every penny. Looking forward to trying it with the new Vitamin C cream.
    The best
    I use this at night along with Sunday Riley Luna oil over the top and it's amazeballs. Will never stop buying Sunday Riley products they are just brilliant.
    Great product
    Love it saw great results in just two weeks and i will keep on using it
    Gave me awful skin
    After I started using this I began getting weird under-the-skin pimples, like tiny bumps under my skin (similar to milia). I gave the product the benefit of the doubt and carried on using it, as I thought the reaction might have been caused by another product, as Retinol is meant to be one of the things that targets spots and milia. But I slowly phased out the other things I was using until only this was left. I then removed this from my regime and since then no new bumps have occurred and my skin has finally started clearing up. I persisted with this for 6 months, and my skin looks so much worse now than it did before. The pimples have left scars and blemishes all over my chin and jawline. I am really disappointed and so upset about the impact it's had on my skin - it has caused me so much upset over the last few months. I don't have sensitive skin at all, and I've never had a reaction to a product before. I would avoid this product.
    Love it
    My skin improved after using this. i will continue use and let's see if i will bought 2nd bottle.
    Amazing!
    I have been using this for around 3 months now, every other night, and can 100% see a difference. Pores are smaller and deep wrinkles on the face and forehead have reduced. Will definitely be purchasing this again!
    Loving it
    Using this every other night and I'm definitely seeing a difference in my skin, which almost never happens
    Amazing
    This is my favorite product. It works wonders.
    Amazing
    So I have slight acne, red spots and always breaking out ... took a chance buying this and I read the reviews and watching their YouTube vlog about this serum and it made me get it. After a week of using this serum my skin has improved massively like I cannot believe how clear my skin is and looks and feels a lot smoother. Deffo a must buy and I appreciate the dosage. In the day time I Always use spf and use this serum in the evening. It’s best to follow the advice on the packaging. I’m dreading ever running out. Absolute godsend I also have before and after pictures which you can tell a massive difference. It’s a must guys xx
    Sunday Riley
    I LOVE this product!! I was looking for a stronger retinol formula since I have used these products for a long period of time, and it works without irritation.
    Favourite retinol
    I have tried DE A Passioni for three months and disliked it. This is so much nicer; lovely texture and a lot less irritating. I’ve only been using it every other night for two weeks so have yet to see real results but v happy combining this, Juno oil, the Inkey List Hyaluronic Acid and my basic CeraVe face moisturiser.
    Ok
    Was nothing special
    The best
    This serum really makes a difference. It does what it claims. This is my second bottle.
    Best ever?
    Bought with Juno oil as my foray into SR products and so far so good that I'm buying other SR products! As a previous retinol user went straight to nightly use with no dryness or redness, complexion bright, smooth and more even. Totally recommend.
    2DAYS IN
    So I have only been using this retinol for 2 nights so far. Due to being a fairly new retinol user I am following the advice of using this 2 nights and slowly building to every other night and then to every night. I was recommended to get this product by my skincare guru best friend. After using this for only 2 nights I am very excited because I can already see astonishing improvements in my skin texture AND PORE SIZE! I am very excited to continue using this product I have always wanted to become a Sunday Riley user due to the high quality ingredients and hybrid of natural and chemical. I will be watching the results closely and will review again in 4 weeks. So far very good!
    Careful
    I would be careful with this product if you have sensitive skin, I suggest definitely doing a test patch first. A little bit of this product goes a long way and it does work. With that being said, the first time I used this my face completely dried out for a week, I had to put moisturizer on 2 to 3 times a day to stop the flakiness. But once that cleared, but face was radiant underneath. But still - I am not sure if it’s a risk I will continue to take? Perhaps a product with lower retinol percentage will work better on my skin.
    Game changer
    Nothing has ever improved my skin this much. Absolutely loved it and 100% repurchasing it!
    Amazing product
    I’ve been using near 2 months and I must say I can see the difference, my skin is clearer and brighter, I use it alternating with vit c cream and my skin seems to have more of a glow. I defo recommend this product and will be buying again.
    SUNDAY RILEY A+ High-Dose Retinoid Serum
    This is amazing. I have been using it for 2 months. I use it on alternate days to the ALPHA-H Liquid Gold tonic. These two together have really helped to clear up my acne scars which I have been trying to get rid of for years. I have also built up my tolerance to retinol over the last few years.
    About order
    Best ever. I'm 60 years old and tried everything. This is the best. Its high dose hasn't at all irritated my skin. It's amazing my skin looks radiant.
    Best Retinol Ever
    This is my HOLY GRAIL retinol product and staple in my routine. It is the only retinol that hasn't broken my acne-prone skin out or burnt my skin, and has actually worked. Not only is my acne cleared but my skin texture has improved and I get so many compliments. This product is gentle yet very effective and I will keep repurchasing.
    Very good
    This product is very good. My skin was smoother and clearer after using this. Much better results than I achieved with Luna Oil. I like the thin consistency much more too. It sinks in and does not sit on my face like the Luna Oil. I have no problem with the light scent. It doesn't last after application anyway. I use it 2-3 times a week and do not have any problems with peeling or irritation, although I should mention that my skin is fairly used to peels and retinoids. I am using it with the CEO Oil and it is a good combo.
    Great product
    I bought it a couple of months ago and used it about 3 times per week. I love it. My skin didn't get flaky, no irritation. I wake up with healthy looking skin. I will repurchase it for sure.
    A-M-A-Z-I-N-G
    For years I have suffered from Acne and after I finally found a routine which has cleared up my skin, I was left with a lot of acne scars. I have tried lots of things including different kind of retinols and retinoids aswell, they were not really working. When I started using this I was really impressed by the look of my face the next morning. Ever since my acne scars have faded and they are 60% less visible. I am finally comfortable being without foundation and this is something I wish for years now. So there is no way on this earth I would switch this product to something else. 10/10
    Great for my acne prone skin
    Started using for 3 weeks and I felt that my monthly hormonal acne life cycle seems shorter and acne scars faded faster. This is becoming a bottle that I frequently reach out for my night time regime.
    I see results
    I purchased and have used this serum for a week now and I already see results. My skin was always dull, with dark scars from old pimples and generally not even. I use the serum along with the CEO glow oil and the Good Genes (was a trio when I bought it). I use it carefully as the instructions say, because I'm new to retinoids, and already my skin is glowing and my scars are fading. Also, I have been using The Littles by Drunk Elephant for a week now and I think all these do a great job in combination. I can't wait to see further results and my skin in a month from now. I will review again for sure because now I did the review just because I'm excited with the results so far!!
    Best Product of 2019
    This product is absolutely amazing. I initially got it as a sample and just had to purchase the full size. This is a high strength retinoid without the irritation, peeling and flakiness. I saw improvement in my skin texture and pigmentation soon after using it. The serum is light weight and sunk into my oily, acne prone skin immediately. I have used many Sunday Riley products and this is by far the best. If you are in the market for a serum, look no further! You will wake up with an even, glowing face. It was a pleasant surprise to find a deluxe sample of the CEO Glow and the Good Genes in the box, nice touch!
    Fabulous
    High strength and very comfortable on the skin. I followed the instructions, eased myself into this gradually and didn’t suffer any irritation. Made my skin lovely and radiant .
