Skin Benefits

May help skin look more elastic and refined, lending a smoother, bouncier appearance, though evidence in cosmetics is still emerging and results can vary.

Uses In Skincare & Cosmetics

Commonly included in serums and eye creams aimed at early signs of aging, and also used in lightweight moisturizers to support a firmer-looking complexion.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Generally considered low-irritation, but patch testing is prudent for sensitive skin or use near the eye area. No known specific regulatory restrictions at typical cosmetic levels. Discontinue if redness or stinging occurs.

Is Tridecapeptide-1 a Good Ingredient?

It rates Fair because cosmetic evidence is still preliminary and real-world benefits are inconsistent; peptides of this size can also face stability hurdles without supportive formulation. Minor irritation or sensitization is uncommon but possible, especially in concentrated serums or around the eyes.
