A SkinCeuticalsAcetyl Hexapeptide-8 A peptide studied for the appearance of expression lines around the eyes.
A peptide studied for the appearance of expression lines around the eyes.
Type of support: Ingredient study
Editorial draft · Qualified scientific review pending.
What it is A synthetic peptide investigated under the name Argireline. The study concerns a specific preparation, not every product listing this ingredient.
Why it is used Studied as a cosmetic ingredient for reducing the appearance of eye-area lines.
What the evidence means A four-week randomized placebo-controlled trial enrolled 60 Chinese participants (3:1 allocation) and reported improved eye-area wrinkle measures. The inspected abstract does not establish results for the retail serums here or long-term benefit. A 24-hour laboratory skin-penetration study is a different kind of evidence, not a clinical efficacy trial.
Precautions and possible reactions The 2025 safety panel concluded safe cosmetic use up to 0.005%; above that, it found insufficient data to determine safety. This is not evidence of harm above that amount. The pure-peptide concentrations in these compared serums are not verified, so this assessment cannot certify either bottle. A commercial blend percentage is not automatically the pure-peptide percentage.
Cosmetics can cause irritation or allergic reactions. Check the full ingredient list and follow product directions.
What this means for your comparison There is human research on a preparation of this ingredient. That is different from a direct test of this serum.

What these differences mean Different names do not tell us which serum works better. Some selected ingredient names match, but amounts and the rest of each formula may differ. Open an ingredient explanation to see its intended use and the kind of evidence behind it.
Check the whole product for precautions. An ingredient name cannot predict your skin’s reaction. Cosmetics can cause irritation or allergic reactions. Check the complete label and follow the product directions.
FDA: cosmetic reactions and precautions One ingredient study does not rank these serums. Studies of an ingredient, supplier descriptions and brand claims answer different questions. We have not recorded an independent head-to-head study of these two serums. Lower cost per mL does not establish better results.
