This works better than any other retinol serum. I have tried many others but none work as well. Zero irritation. Sinks into skin quickly so easy to layer. Love everything about it, especially that it makes a noticeable difference in my skin.

This is a pretty powerful serum that really helps with skin turnover and cell renewal. I use it every other night mixed with the antioxidant dew. Both products make my skin glow and keep it clear. A bonus- the light scent is so fresh and clean. Kypris makes my favorite serums for sure!

This worked like a miracle.I am not big in skincare but started trying to see what works for me and this product won me over a thousand times.Before getting this I had a dark spot on my nose for about 3 weeks and on the first night of using it I could already see that mark get lighter, on the fourth day it was already gone.I use this at night after washing face and neck with "Ursa Major" face wash, then I apply this Kypris serum, following with "Alpyn" face lotion on summer or "Goop" face lotion on winter.In the morning I use vitamin C serum by "Ursa Major", face lotion (same as nighttime) and "Suntegrity" sunscreen 30SPF.

I have been using this product every night for about a month and have already seen a noticeable difference in my skin. The main thing I notice is how the texture of my skin has improved, especially my forehead which is much smoother. I have not experienced any irritation or redness at all which I have experienced with nighttime exfoliators in the past. It's wonderful and I would highly recommend!
