Science
Mechanism of Action
This ingredient functions by forming a thin, invisible film when applied to the skin, which acts as a physical barrier. This film assists in skin protection. Concurrently, Polyamide-7 serves as a binding agent, helping to coalesce and hold various cosmetic ingredients together, thus maintaining product consistency and stability.
