OS-01 (OneSkin Peptide)

OS-01 is a proprietary peptide developed by OneSkin that targets cellular senescence in skin cells. It was identified through a high-throughput screen of peptide libraries for senolytic/senomorphic activity. Used in the OneSkin topical product line.

Category: Anti-Aging / Cosmetic. Evidence rating: D (animal/preclinical only).

Clinical status: Cosmetic product (OneSkin)

Reduces senescent cell burden in skin tissue and decreases senescence-associated secretory phenotype (SASP) factors. Improves epidermal barrier function and reduces skin biological age as measured by molecular markers.

Safety considerations: Well-tolerated in available studies.
