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.

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!

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. ❤️❤️❤️

Dried my skin out too much and caused an acne outbreak
Unfortunately, my skin does not agree with this face wash! I wanted to love it so much because I do love their moisturizer. But the face wash dried my skin out so badly which in turn caused my skin to become overly oily and resulted in tons of acne breakouts. This was not from "purge" or skin sluffing. It was straight up dry skin resulting in too much natural oil production resulting in loads of white head tiny pimples. I switched back to my Neutrogena hyaluronic acid face wash and my skin cleared up in about a week even though I'm still using the OneSkin moisturizer.
