Mechanism of Action (MOA)
Pentapeptide-21 is a synthetic signaling peptide composed of five amino acids. It is designed to interact with skin cells by mimicking fragments of naturally occurring extracellular matrix proteins. This peptide supports cellular communication pathways that are associated with the regulation of extracellular matrix components, such as collagen and fibronectin. Through these biochemical interactions, Pentapeptide-21 contributes to the maintenance of skin’s structural integrity and overall appearance.
Pentapeptide-21 is suitable for incorporation into a variety of cosmetic formulations targeting skin care. - Recommended for use in facial serums, creams, and lotions - Can be added to eye contour products - Compatible with both day and night skin care formulations - Suitable for inclusion in sheet masks and leave-on treatments - May be formulated into lightweight gels or emulsions - Typical use level: 0.5–2%, depending on formulation requirements
