Hexapeptide-11 is a six-amino-acid peptide, often produced by fermentation, for cosmetic applications. It's included to improve the look of elasticity and tone while smoothing skin feel, but current evidence is limited and results may be subtle.
Not typically evaluated for comedogenicity — no standardized rating available.
Our take
Is Hexapeptide-11 a Good Ingredient?
It's Fair because the support for elasticity and firming is limited, so results are often subtle, and there's a small risk of irritation or sensitization on top of that thin evidence base.
