Science
Mechanism of Action
HEXAPEPTIDE-38 operates by significantly modulating adipocyte activity and enhancing dermal integrity. It demonstrably increases PGC-1α (Peroxisome proliferator-activated receptor gamma coactivator 1α) expression by 61.1%, which is critical for cellular energy metabolism and subsequently augments the lipid storage capacity within mature adipocytes. This action is complemented by its ability to boost adipocyte differentiation from subcutaneous preadipocytes, fostering enhanced lipid accumulation for targeted volume growth. Additionally, the peptide activates the skin's intrinsic repair mechanisms, elevates dermal collagen content, and reinforces the dermal-epidermal junction (DEJ) for superior structural support.
