Science
Mechanism of Action
This extract utilizes a diverse phytochemical profile to enhance skin health: Chimaphilin provides targeted antimicrobial action, while natural arbutin precursors inhibit tyrosinase to modulate melanin production. Additionally, high concentrations of tannins provide an astringent effect, and its interaction with TRPM8 receptors induces a refreshing, cooling sensation upon application.
