Science
Mechanism of Action
HYDROXYPROPYLTRIMONIUM HYDROLYZED JOJOBA PROTEIN operates by establishing a moisture-attracting, hygroscopic film on the skin's surface or hair strands. This film actively draws and retains water molecules from the surrounding environment, thereby delivering a sustained moisturizing effect. Its humectant action contributes to skin softening, which can temporarily improve the visual aspect of fine lines and wrinkles.
