Think of senescent cells like that one moldy raspberry in the carton—if you don’t address it, it stresses the healthy ones around it. That’s the thinking behind OneSkin. Their OS-01 peptide was developed by a biotech team to help skin cells behave younger by reducing the impact of senescent cells on the skin’s appearance. This is why OneSkin calls it a topical supplement—you don’t swallow it, you apply it. Used after toner and before your moisturizer, it layers easily with actives like retinoids and chemical exfoliants. It’s skin longevity science, applied directly to the skin, focusing on how your skin cells age—not just how your skin looks today. Topical use only. This product is a topical skin supplement designed to support the appearance of skin longevity and does not diagnose, treat, cure, or prevent any disease. LTKOver40 LTKBeauty LTKHoliday
