Pentapeptide-21
What is Pentapeptide-21?
Pentapeptide-21 is a synthetic oligopeptide composed of a precise sequence of five amino acids, engineered in laboratories for cosmetic applications. It falls into the peptide active category, primarily featured in anti-aging serums, creams, and moisturizers designed for facial care. In formulations, it acts as a signaling agent that penetrates the upper skin layers to interact with fibroblasts, promoting the natural synthesis of extracellular matrix components such as collagen and elastin. This mechanism supports the skin's structural integrity and resilience without relying on harsh exfoliants or fillers. Its water-soluble nature allows easy incorporation into water-based products, where it remains stable and bioavailable at typical usage levels.
