What the gurus are saying

The OS-01 peptide targets senescent cells (zombie cells nearing the end of life) to make room for healthier skin, an approach aging experts enthusiastically back. Doctors, however, question whether this structurally changing the skin crosses into drug claims, which fall outside cosmetics, and worry about the high price, though some remain open to trying it. For use, apply at night to the neck, then layer a retinoid and barrier cream.

"This is by OneSkin, a peptide called OS-01. I put this on first on the neck to get rid of the senescent cells, the zombie cells that are about to die. I do this at night, then follow with a retinoid, then a barrier cream, sandwiching the retinoid in between so it does not dry out or irritate the neck."

Microneedling Q&A Seriously, ask me anything
"I'm a big fan of that OneSkin. Huge fan. That's the skincare that uses that OS-01 peptide that helps to rid the body of senescent cells. So it clears the way for those skin cells that you want to receive all of those good peptides and all of that good skincare. It's like, okay, let's prioritize who we're getting it to. We'll clear out all the ones that are dying, right?"

"OneSkin's OS-01 claims to reverse the signs of aging by disabling damaged skin cells, which is borderline a drug claim because it structurally changes the skin, which cosmetics isn't supposed to do. I am skeptical when it comes to high price skincare, and I think your best bet to age healthier or preserve the health of your skin while aging is to wear sunscreen, moisturize regularly, and make healthy lifestyle choices. But I am willing to give it a go, because I've lost quite a bit of weight over the last year and a half, so if anything could make the skin on my body reverse age, that would be much appreciated."
