Science

Mechanism of Action

This ingredient functions by forming a breathable, protective film on the skin's surface, which helps to minimize transepidermal water loss, thereby conditioning and protecting the skin. Its polymeric structure acts as an effective emulsifier and stabilizer, preventing the separation of oil and water phases within a product. The large molecular size ensures it remains on the skin's surface, creating a barrier against environmental stressors. It also contributes to enhanced product spreadability, a soft, smooth skin feel, and an optical blurring effect that subtly reduces the appearance of fine lines and pores.
