Science
Mechanism of Action
This ingredient operates by filling microscopic gaps between dead skin cells on the skin's outermost layer. This action makes the skin feel noticeably softer and appear smoother. Additionally, it forms a fine, protective film on the skin's surface, which is crucial for maintaining the natural lipid barrier and safeguarding the skin from external stressors.
