Science

Mechanism of Action

Operating as a natural micronized polymer filler, Hydroxybutyric Acid/Hydroxypentanoic Acid Copolymer physically refines the skin's surface. Its unique structure enables it to diffuse light, creating a soft-focus effect that diminishes the visibility of fine lines and uneven skin tone, while simultaneously absorbing excess oil to provide a matte finish. Furthermore, it offers a gentle abrasive action to aid in surface exfoliation.
