Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In people washing forearms with common skin cleansers, the amount of the body's own LL‑37 on the skin surface fell slightly but significantly shortly after washing.

    In plain wordsAfter forearm washing with common cleansers, the body's own LL‑37 on the skin dropped slightly for a short time.
