Men's skin has its own risks because of androgen hormones. High concentrations of testosterone and its derivatives (dihydrotestosterone) provoke an increase in trans-epidermal water loss (TEWL), affecting barrier function and reducing cAMP (central second messenger) levels involved in multiple cellular processes.

Acetyl Hexapeptide-20 exhibits a dual beneficial effect on men's skin, including:

Skin metalloproteases inhibition (MMPs).

Trans-epidermal water loss(TEWL) reduction.

MMPs are metal ion-containing enzymes responsible for extracellular matrix (ECM) proteins' destruction. They break down skin collagen and elastin resulting in fine lines and wrinkles. Acetyl Hexapeptide-20 inhibits those enzymes, changing the protein production/destruction balance and increasing collagen and elastin quantities in the skin.
