Data on OneSkin ' s Peptide 14, a Topical Senotherapeutic, in Human Skin Models and Skin Biopsies

You might recall that OneSkin recently launched a cosmetic product claimed to reduce levels of senescent cells in aged skin, as measured by the usual markers for cellular senescence, such as p16 expression and senescence-associated β-galactosidase. Removal of senescent cells is more or less literal rejuvenation, given that the accumulation of such cells drives chronic inflammation, tissue dysfunction, and degenerative aging. Clearance of a large fraction of senescent cells via senolytic drugs has been shown to extend life and turn back measures of aging in a number of animal studies. The OneSkin product contains a bunch of the usual things one puts into skin care products, all of which can be safely ignored, but the core of it is peptide 14, also called OS-01 and decapeptide-52. This may or may not be a senolytic compound, capable of selectively destroying senescent cells to some degree. The evidence presented in today's preprint paper suggests that the observed effect on markers of cellular senescence is more likely achieved by preventing at least some cells from entering the senescent state. In this, the use of peptide 14 might be similar in outcome to the topical application of rapamycin. In that case, researchers are fairly confident that no direct destruction of senescent cells is taking place, only a reduction in senescent cell creation and activity. This can be enough in aged skin to allow existing processes of senescent cell clearance to catch up over a...
