What it is
Acetyl Octapeptide-3 is a synthetic peptide built from eight amino acids and capped with an acetyl group for stability. It is used in skincare as a conditioning agent and is typically formulated at low concentrations. It is one of the more widely used cosmetic peptides and appears in a variety of leave-on products.
Safety & warnings
Synthetic peptides of this type are generally well tolerated at the low levels used in cosmetics and are not typically linked to comedogenicity or fragrance sensitivity. Patch testing is a sensible precaution for those with reactive skin.
Origin & sourcing
Synthetic, produced by peptide synthesis to create a specific eight-amino-acid sequence that is subsequently acetylated.
