Love this product! I've been using for a little over a month and I've noticed a smoother skin texture and overall skin tone. Was using products containing retinol before, which can dry out your face (especially in the winter). After switching to OneSkin and cutting out retinol, my redness and fine lines are finally going away. Excited to see even more improvement with more use!

I cannot believe how good and fast this works! I started using it on Dec. 21, 2022 and I can see amazing results after only 8 days, using it twice a day. I just turned 75 this month so I am not talking about it working on a 30 or 40 year old here. I had deep crow feet from hooded eyes and now the crow feet are starting to flatten out. almost disappearing. When I say it actually works, it’s not just maybe it looks a little better, I can definitely see a big difference. I was waiting until at least the second or third weeks to take pictures of my before and after. The picture on top is today, the bottom picture was taken on October 8, 2022 when I starred the face OS-01. I am seeing amazing results.

I was concerned about crepey skin on my arms, shoulders and hands. No matter how much regular moisturizer I used it wasn’t changing how my skin looked. After just a couple weeks of using the body lotion I am already seeing a difference AND other people are also noticing that my skin looks better.

My skin has 71 years of experience and I have spent at least 50 of those years in search of the perfect UV protection. So I've been through a lot of products. OS-01 Shield Protect is my favorite because it goes on like a very nice facial cream and it is not oily. My skin is sensitive and I have not experienced any negative affects or reactions. I have been using this for 4 months and will definitely recommend this to friends and family.

One Skin first appealed to me because of who created the company - 4 badass brilliant women with PhDs. I was impressed and intrigued so I ordered the products. I love ALL OF THEM. The Daily Face Cleanser is BEYOND! LOVE the ingredients! LOVE how my skin looks and feels after I use it! LOVE that I can trust it. THANK YOU!!!
