Science
Mechanism of Action
Hexapeptide-33 exerts its effects by stimulating angiogenesis (blood vessel formation) and promoting the growth and differentiation of dermal cells. It specifically enhances the synthesis of Type I collagen, crucial for maintaining skin's structural integrity, elasticity, and firmness. The peptide contributes to skin brightening through a dual mechanism: inhibiting melanin synthesis and directly reducing tyrosinase activity. Furthermore, Hexapeptide-33 acts as an antioxidant, encourages cell migration vital for repair processes, and targets Adhesion G-Protein-Coupled Receptors (aGPCRs) in keratinocytes, which are key to epidermal differentiation.
