Argireline

Argireline is a cosmetic peptide that inhibits SNARE complex formation and is marketed as a topical alternative to botulinum toxin for expression lines. Human cosmetic studies suggest modest wrinkle-reducing effects.

What it is

Argireline is the brand name for acetyl hexapeptide-8, a synthetic peptide designed to mimic the N-terminal end of SNAP-25 and compete for a position in the SNARE complex, theoretically reducing acetylcholine release and muscle contraction. It is used in anti-aging cosmetics.

What the evidence shows

Small human cosmetic trials, including one sponsored by the manufacturer, reported reductions in wrinkle depth around the eyes and forehead after several weeks of topical use. Effects are mild and temporary; Argireline does not paralyze muscles like botulinum toxin.

Risks & unknowns

Topical Argireline is generally well tolerated. Mild irritation or allergic reactions are possible. It is a cosmetic ingredient and has not been evaluated by the FDA for therapeutic use.

Legal / regulatory status

Argireline is regulated as a cosmetic ingredient. It is not an FDA-approved drug and cannot be marketed to treat wrinkles as a medical condition.
