Science
Mechanism of Action
This ingredient possesses a positive charge, facilitating an electrostatic attraction with the naturally negatively charged surface of the skin. This enhanced affinity significantly improves its adsorption, allowing it to adhere longer and resist being easily removed. It functions as a powerful humectant, drawing and retaining water to deliver deep and sustained hydration. By forming a protective, breathable film on the skin, it strengthens the skin barrier and helps to alleviate irritation. Furthermore, it is observed to stimulate collagen production, enhance skin elasticity, and visibly diminish the appearance of wrinkles, while also contributing to pH regulation and acting as an antioxidant.
