Argireline

Acetyl Hexapeptide-8 (Acetyl Hexapeptide-3)

Research useEducational entry
Mechanism

A topical synthetic hexapeptide that interferes with the SNARE complex to reduce neurotransmitter release, proposed as a mild, botulinum-toxin-like way to relax expression-line muscle activity in the skin surface.

Evidence

Marketed cosmetic ingredient with modest supporting evidence; early studies report reduced wrinkle depth, but effect sizes are small and much weaker than botulinum toxin. Cosmetic use only — not a drug.

Applications
  • Topical anti-wrinkle cosmetics
  • Expression lines (forehead, crow's feet) in cosmetic formulas
  • Common in serums and creams at low percentages
Protocol

Educational overview only — no dosing instructions in the public hub. Used topically as a cosmetic ingredient, typically at low single-digit percentages in finished products.

Risks

Generally well tolerated topically; possible mild irritation. Cosmetic claims often exceed the modest clinical evidence.

Quality

Buy from reputable cosmetic suppliers with an INCI listing and batch documentation; concentration and formulation matter more than brand claims.

Legal status

Approved cosmetic ingredient (INCI: Acetyl Hexapeptide-8); sold in over-the-counter topical cosmetics. Not an approved drug and not for injection.
