Science
Mechanism of Action
This peptide primarily functions by inhibiting matrix metalloproteases (MMPs), which are enzymes responsible for breaking down crucial extracellular matrix proteins like collagen and elastin. By mitigating MMP activity, Hexapeptide-20 helps restore the balance between protein synthesis and degradation, leading to an increase in collagen and elastin levels within the skin. Concurrently, it reduces trans-epidermal water loss (TEWL), thereby enhancing skin volume, elasticity, and overall density. It also supports the skin's natural repair processes and protects against both chronological aging and environmental photoaging.
