A cosmetic peptide used to help soften the visible appearance of expression lines and support smoother-looking skin.
Acetyl hexapeptide-8, commonly known by the trade name Argireline in some formulas, is a synthetic peptide used to target the appearance of expression lines. Its cosmetic role is different from injectable treatments: it is applied topically and is intended to support a smoother visible appearance rather than produce medical muscle paralysis.
Usage & cautions
Generally well tolerated. Patch test if skin is reactive.
Information approach
Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
