Science

Mechanism of Action

This ingredient operates by forming a hygroscopic film on the skin's surface, which actively attracts and retains moisture, effectively combating dehydration and acting as a robust moisturizer. Beyond hydration, it contributes to refining skin texture, imparting a softer and smoother feel, and supports the integrity of the skin's essential barrier function. The hydrolyzed jojoba protein component is additionally theorized to diminish the appearance of age-related concerns such as fine lines and wrinkles.
