What Is Tetrapeptide-14?

Tetrapeptide-14 is a synthetic peptide designed to support the skins innate immune system. It helps activate the skins natural defence mechanisms against pathogens and environmental stressors.

The peptide works by stimulating the production of antimicrobial peptides (AMPs) in the skin. These natural molecules are the skins first line of defence against bacteria, viruses, and fungi.

Tetrapeptide-14 is particularly beneficial for acne-prone skin and for supporting skin recovery after treatments or environmental damage.
