Science
Mechanism of Action
PCA Dimethicone/Bis-Vinyldimethicone Crosspolymer functions by creating an invisible, resilient polymeric barrier on the skin. This barrier prevents transepidermal water loss, thus prolonging skin hydration and offering protection against external environmental factors such as pollution and temperature fluctuations. Its unique structure enables it to absorb excess oil and sebum, making it beneficial for managing shine, while simultaneously improving product spreadability. Additionally, it can contribute to a subtle optical blurring effect, visibly minimizing the appearance of fine lines and pores, and acts as a robust emulsion stabilizer within formulations.
