Nothing. None of the experts who reviewed it raised a problem.

What the gurus are saying

This cleanser's OS-01 peptide formulation earns praise for noticeably changing skin texture and tone during regular use. The formula transforms into a light foam that delivers a deeper clean in warm weather, though it appeals most to those who want an effective peptide treatment they can rinse away rather than a leave-on product. Gurus value it as a capable daily cleanser that justifies its cost through visible results, making it a solid pick for a nighttime double cleanse.

"The OneSkin Cleanser turns into a light foam and in hot weather, it just gives me that deeper clean that I really need at the end of the day. It's funny cuz I don't really lean into the foam cleansers, but I really do in this type of instance. I even bring a couple of these little sponges to make sure that everything comes off properly because if you don't get that right, like nothing else really matters anyway."

"This gets a maybe a two for sting factor. It really only stung my face when I was very sensitive. When I wasn't sensitive, it was fine, but it completely left my skin stripped. It gets a zero for moisturization. I know it has its magical OS1 peptide, which I rave about. But for me, their cleanser too foaming, too stripping, and not quite comfortable enough for my sensitive skin."
