Noticeable results
Loving this cleanser. After using it consistently, I’ve noticed real results—my skin already looks firmer and feels smoother overall.

Holy grail cleanser!
This is my new HG cleanser! I’m a 50 y/o F OSPW: oily, sensitive, pigmented, and I have a tendency to wrinkles due to sun damage in my youth. This cleanser reduces my red cheeks, nose, and chin. I have had zero sensitivity to it and zero breakouts! It cleanses very well but doesn’t strip my skin at all, and it doesn’t sting my eyes. I love everything about it!

Best Product Out There 🎉
I have used skin ceuticals for years and once I tried One Skin PREP I was addicted. Love this product it’s amazing. I am 54 and have VERY sensitive skin and this product was MADE FOR ME! I absolutely love this product line and will never go back to my old routine. ❤️❤️❤️

Don’t believe the hype!
I should have known… if it seems too good to be true it probably is. And that’s definitely the case with OneSkin’s product line which claims to turn back the clock on aging skin. Not only is it overpriced, it will wreak havoc on anyone with sensitive skin. I too was lured in by the Instagram media blitz. But I delayed jumping on the Instagram band wagon given the astronomical price of OneSkin’s products. I then threw caution to the wind, and purchased OneSkin’s PREP facial cleanser and the OS-01 Face Topical Supplement moisturizer through Amazon. And OMG! The reaction was immediate and intense! It took just a couple days (two to be exact) before my face was ON FIRE every time I applied these products. What’s worse, my skin turned beet red, began peeling and then the breakouts began. As a 58 year old woman who bought these products because of their purported anti-aging benefits, I assure you that the return of acne was not what I was looking for!

Doesn’t dry my skin
I have not looked up all the ingredients but it doesn’t dry-out my already dry skin. It also cleans well removing dirt and oils.

Love this Facial Cleanser/ Prep from One Skin
I wasn't sure what to expect with this. The line was recommended to me by a Functional Dr. I started out just ordering samples and reading more about it, including the scientific studies. I ordered samples of the different products. I have to say, I love this! ! It lathers up nicely between damp hands, glides nicely, and feels amazing on the face. I am definitely a fan!

Very cleansing and gentle
I was amazed the first time I used it. Best when paired with their lotion. I'm 67 and have Rosacea. Even though it's not made for this I find it very calming and soothing. I highly recommend.
