About R-(METHIONYL SH-OLIGOPEPTIDE-1 OLIGOPEPTIDE-164)
A growth-factor-style peptide active that is more controversial than ordinary conditioning peptides.
Detailed Analysis
R-(METHIONYL SH-OLIGOPEPTIDE-1 OLIGOPEPTIDE-164) is a recombinant growth-factor-style peptide or peptide fusion used for repair or anti-aging marketing. Even though large peptides usually penetrate skin poorly, bioactive signaling proteins draw more caution than bland cosmetic ingredients because long-term independent data are limited and the biology is more complex. That keeps the score in the moderate band instead of the high-safe band.
