About

A lab-made peptide used to condition skin and support repair or anti-aging claims, usually at very low concentrations.

Octapeptide-40 is the synthetic peptide consisting of arginine, glycine, leucine, lysine and serine. This is a synthetic peptide used as a signaling or conditioning active in cosmetics. Peptides are usually used at very low concentrations and are not strongly associated with classic systemic toxicity on intact skin, but independent human evidence is often limited and many efficacy claims are supplier-led.
