Science

Mechanism of Action

This silicone-based polymer functions by creating a flexible, three-dimensional network structure on the skin's surface. This matrix significantly improves the uniform spread of formulations, resulting in a smoother application and enhanced slip. As a skin conditioning agent, it forms a protective yet breathable barrier that helps to retain moisture, contributing to softer, more supple skin. Furthermore, it creates a soft-focus effect, subtly diminishing the visibility of fine lines, wrinkles, and uneven skin texture. Its absorbent properties are key to managing excess sebum and reducing shine, providing a desirable matte appearance. In cosmetic formulations, it also acts as a thickening agent, emulsion stabilizer, and viscosity controller.
