The study

The participants applied OS-01 cream or the control cream to their body twice daily. The study assessed changes in skin on the forearms and upper arms.

OS-01 improved hydration on both the forearms and upper arms, but the control cream improved only the skin on the forearms. This was the only measurement that showed a statistically significant difference between the groups.

The study’s authors were either inventors of the OS-01 peptide or employees of the company that owns the patent for the peptide.
