Pentapeptide-18

Functionpeptide

What it is — Pentapeptide-18 (INCI: Pentapeptide-18) is a synthetic signal peptide used as a skin-conditioning ingredient.

What it does — It is used in formulas positioned around a smoother-looking surface and the appearance of expression lines. Descriptions here are cosmetic — about look and feel — rather than a medical or muscle-relaxing effect.

Typical use — It appears in serums, essences, creams and eye products, usually at low levels within a peptide blend.

Who it suits / good to know — Generally low-irritation and suitable for most skin types. Peptides are supporting actives whose feel builds gradually with consistent use rather than overnight.

Safety — DHALIORA grades it low risk: a low-hazard peptide at cosmetic use levels. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low-hazard peptide at cosmetic use levels.
