Mechanism of Action

Dipeptide-15 functions as a bio-regenerative peptide, stimulating the synthesis of essential epidermal proteins and structural components like filaggrin and ceramides. By optimizing cellular hydration mechanisms, it reinforces the skin’s protective barrier. The peptide also triggers fibroblast proliferation and enhances dermal matrix regeneration, improving elasticity and reducing visible aging signs.
