Description
Pentapeptide-18 Overview
Pentapeptide‑18 is a synthetic neuropeptide composed of five amino acids, widely used in cosmetic research for its ability to support the appearance of relaxed, smoother-looking skin. It acts through mechanisms inspired by neurotransmitter pathways, often explored in cosmetic science for expression-line targeting applications.
When used in prototype formulations, Pentapeptide‑18 has been associated with improved skin texture and perceived skin firmness, particularly in combination with other well-known peptides such as Acetyl Hexapeptide‑8.
For cosmetic R&D and laboratory use only. Not for injection, ingestion, or therapeutic applications.
