OS-01 FACE
See why customers love OS-01 FACE
“I stopped using retinol which caused me to have rough, red patches, but kept my skin supple and smooth…and now using OneSkin I still have the wrinkle reduction effects and smooth skin without the negative effects.” – Tova N.
"I love this science-backed product. It truly makes a difference to my skin and has allowed me to pare down all the other lotions, potions, & products that were more reactive in nature vs this proactive approach. Not only have I saved money on my skincare routine, but I've witnessed even skin tone, more elasticity, and a reduction in forehead wrinkles. Would recommend again and again. Can't wait to see what they think of next!" – Laura E.
"It’s working great!!! It absorbs quickly. I see and feel a significant difference in my skin’s texture and radiance. My skin looks smoother and feels firmer. I highly recommend it for anyone serious about maintaining youthful, healthy glowing skin." – Ildiko C.
"One skin really loves my skin. I no longer use retinoids and put up with their side effects. One skin feels so effective as it absorbs quickly leaving my skin more even, bouncy and fresh." – Sarah B.
OS-01 EYE

“The concentration of peptides in this product has made a difference, especially to the circles under my eyes. I haven’t needed to use concealer since beginning to use this product. The science behind this product is solid.” – Kathy L.
"I've tried all sorts of different eye creams; the best out there. I have a very thin skin around my eyes with many expression lines and wrinkles and this product has been the most efficient in minimizing them and nourishing my skin. I all using this day and night very religiously and have no intention of ever stopping." – Archontia T.
"I simply love One Skin OS-01 Eye cream. It is silky smooth, absorbs efficiently, and never feels heavy or greasy. I have noticed the fine lines under my eyes and early crows feet slowly vanishing. It's subtle but evident the more I use it. This is the best product I have ever tried." – Bridgette G.
"OS-01 EYE is fantastic. I wish I had taken pictures when I started using this a year ago. I'm certain my eyes look better now than they did before. It absorbs immediately and yet is there moisturizing the area around my eyes all day long. It even smooths out the rough bumps around my eyes. This is a wonderful product. I love it!" – Donna G.
OS-01 BODY
See why customers love OS-01 BODY
“The skin on my legs was starting to look older, dry and crepey at 46. Now it is plump and youthful like it was 10 years ago after only a few weeks.” – Jen A.
"The One skin, OS-O1 Body, has been a game changer, within a few weeks I saw a remarkable difference in the quality of my skin, and my skin's appearance continues to improve with daily application. It now has a tighter, less dry look and the texture has almost returned to my premenopause condition..more moist and fresh in appearance. Science is everything, and One Skin has got the science spot on." – Tia T.
"I love this body lotion. My crepey skin is transforming. I wish I had taken pictures before I started using it but I have tried so many different products with no results that I didn’t have much confidence that this one would be any different. Boy was I wrong. I’m hoping that it will eventually get rid of all my dark spots on my skin. I will be a forever customer..."– Myra P.

The welcome kit was very nice . It was great to try the spf which I shall now order
- JJessicaVerified BuyerReviewingWelcome KitI recommend this productRated 5 out of 5 stars2 hours agoLove the Body Lotion
I got this free with my order and am glad I got it. While the Prep says its gentle enough to use everyday... it was a bit too much for my very sensitive skin. It is a great product, just not right for me. As for the body lotion, I love it. I use it on top of the face lotion and it works great. It doesn't break me out and gives the right amount of moisture for the whole day or into the night. A little goes a long way so it should last a while. Great purchase!!
