Science
Mechanism of Action
This synthetic lipo-peptide, characterized by the sequence Pal-His-Tyr-Arg-Ala-NH2, acts fundamentally by boosting the expression and production of Mohawk, a homeodomain protein naturally abundant in youthful skin. This action consequently stimulates the synthesis of various collagen types and other vital extracellular matrix (ECM) components, while concurrently downregulating genes responsible for ECM degradation. The result is an enhancement in collagen density, organization, and fibril thickness, leading to improved skin integrity. Furthermore, it supports the skin's intrinsic ability to retain moisture by promoting the production of ceramides and other essential lipids, thereby strengthening the natural barrier function.
