Does Argireline help with subjective wrinkle improvement?

C
Grade C — weak human evidence1 RCT (n=60, 4 wk) · effect size: small
Short answerWeak human evidence. 1 RCT (n=60, 4 wk): enough to be interesting, not enough to count on. Where an effect is seen it is a small effect. The subjective arm of the same trial. A 48.9%-versus-0% split is a large number from a small unreplicated study, and subjective grading in a topical trial is the endpoint most sensitive to expectation.

What the studies show

The subjective arm of the same trial. A 48.9%-versus-0% split is a large number from a small unreplicated study, and subjective grading in a topical trial is the endpoint most sensitive to expectation.

A few small or poorly-controlled human studies. Enough to be interesting; not enough to count on. Most of what gets called “clinically proven” online lives here.

  1. 1

In context

Argireline is a synthetic hexapeptide (acetyl hexapeptide-8) modelled on the end of SNAP-25, the protein botulinum toxin cuts, and sold in serums as a topical wrinkle treatment. Its human evidence is one 60-person randomised trial over four weeks, which reported reduced periorbital roughness and a 48.9% subjective anti-wrinkle rate against 0% on placebo. The same study appears three times in the 2013 literature under different titles. It is a legal cosmetic ingredient everywhere LYO covers and is not a medicine.

Argireline is cosmetic ingredient. Legal status differs by country — see the regulation section or the jurisdiction pages.
