Safety

Usually well tolerated and suitable for sensitive-skin products, but patch testing is advisable if you're reactive. No commonly recognized cosmetic regulatory restrictions.

It's Fair because soothing and anti-redness claims lack solid independent clinical backing, even though the peptide is formulated to be gentle. Even calming peptides like this one can occasionally trigger sensitivity.
