Application Protocol

OS-01 is available exclusively through OneSkin's commercial skincare products. Apply a thin layer to clean skin twice daily — morning and evening. The peptide concentration in commercial products is proprietary and not publicly disclosed.

Product Format

OS-01 is not available as a standalone peptide for reconstitution. It is formulated within finished cosmetic products (face cream, body lotion) with additional active and inactive ingredients. No reconstitution or preparation is required.

Usage Duration

OneSkin recommends continuous daily use for best results. Skin rejuvenation effects (senescent cell reduction, improved barrier function) are measured over weeks to months. There is no cycling protocol — the product is designed for ongoing use.

Storage

  • Store at room temperature
  • Keep container sealed when not in use
  • Use within the stated expiration period
