Elevate your skin care routine with A+ High-Dose Retinoid Serum from Sunday Riley. This advanced-strength retinoid serum delivers a 6.5% solution of stabilized retinoid blends and botanical, retinol-alternative extracts into the skin.

Encapsulated CoQ10 helps to improve the appearance of aging or damaged skin, while rare, Hawaiian white honey, bisabolol, cactus extract and ginger balance and soothe the skin for the appearance of calmer, even-toned complexion.

Love this product!
I can't live without this product! I am in my early 40's and this has helped with smoothing my skin and no more adult acne!
Report this reviewExcellent product
Soaks in quickly; not too harsh for my sensitive skin; neutral scent; 5 stars!
Report this reviewGreat serum
This is a great serum. I use it as a preventive measure so I don't know the effect it has on existing wrinkles, but my skin looks great.
Report this reviewGentle, effective retinoid
I am a new Sunday Riley customer. I use this nightly with Sunday Riley Luna night retinol oil every other night. Skin discoloration has improved. Not drying at all, but I have somewhat oily skin. Seems to smooth some fine lines and helps my pores to stay clear. Works great for me. I also have very high retinol tolerance, so not sure for a beginner. This will be a fixture to my night routine until my skin changes again (perimenopausal). Will repurchase, but not from Dermstore.
Report this reviewBright, beautiful skin
This product has really made a difference for me in my skin looking more radiant with continued use!
Report this reviewbest otc retinol
with the exception of getting a prescription, this is the best retinol product on the market
Report this reviewA great retinol
I've been using retinol for a few years now, and have tried a few different brands. This one is my current favorite, and don't see that changing. It's a high-dose, so effective, but doesn't irritate my sensitive skin like others. Get it!
Report this reviewRetinol serum that actually works!!!!!
I tried numerous retinol serums by Skin Medica, IS CLINICAL, Jan Marini and nothing helped my skin. All they did was irritate and dry my skin out. Then I was just browsing through Dermstore and I. Saw this item and after reading the reviews and ingredients info I decided to give it a try: best thing I ever did. I don't mind the price, even though it's not cheap, but the jar is pretty big. It lasted me over 6 months so you end up saving in the long run. It never irritated my skin and I started to see results. With any treatment you won't see results until few months passes with regular use. I feel like everyone's skin is so unique that we have to go through few things before we find THE ONE!!! And I found it!!! It's great stuff ladies ...and gentlemen!!!!
Report this reviewOvernight results
You can literally see the results overnight. Skin looks smoother, brighter, fine lines look firmer. Excited to continue using this in my routine
Report this reviewI love, love, love this stuff
I use this nightly! It works great and smells great, too. It does everything a retinol is supposed to, without being too drying, and making my face red. Excellent product!
