Argireline

The most widely used cosmetic peptide, marketed as a topical alternative to botulinum toxin for fine lines.

Argireline is classified as a cosmetic hexapeptide. Its current development status is: cosmetic use. The published evidence is thin, largely non-independent, or does not address the uses this compound is marketed for.

The Peptide Institute tracks Argireline because it is actively sold through research-compound and telehealth channels. Our interest is narrow and specific: what is actually in the vial, whether the label is accurate, and whether the sellers of it can document what they claim. We take no position on whether anyone should use it.
