Science

Mechanism of Action

This ingredient primarily acts on the skin by attracting and retaining water, thereby boosting hydration and contributing to a softer, smoother complexion. The hydrolyzed collagen component, composed of small peptides, functions as a skin-conditioning agent. The incorporated Lauroyl group bestows surfactant capabilities, enabling it to gently cleanse by emulsifying oils and water, and can also temper the harshness of other surfactants in cleansing formulations.
