Pentapeptide-18
What is Pentapeptide-18?
Pentapeptide-18 is a synthetic oligopeptide consisting of five amino acids: tyrosine, D-alanine, glycine, phenylalanine, and leucine. Developed in laboratories, it mimics natural neurotransmitter inhibitors like enkephalins. This peptide is commonly found in cosmetic products categorized as anti-wrinkle creams, serums, and eye treatments. Its primary function involves penetrating the upper skin layers to act at neuromuscular junctions, where it competitively blocks neurotransmitter release. This modulation reduces the frequency and intensity of muscle contractions responsible for dynamic wrinkles, such as those on the forehead, around the eyes, and mouth. By promoting this relaxation effect, it contributes to a smoother skin appearance over time with regular application. It is typically formulated at trace levels for stability and efficacy in water-based or emulsion products, making it suitable for daily facial care routines focused on expression lines.
