Science
Mechanism of Action
Functioning as an amphiphilic molecule, Polyglyceryl-5 Caprate stabilizes emulsions by reducing interfacial tension between immiscible oil and water phases. It also enhances skin hydration by forming a protective layer that minimizes transepidermal water loss and may improve the delivery of other active ingredients.
