PEG-CROSSPOLYMER

Safety grade: A

This is a synthetic material made from polyethylene glycol (a common ingredient in many products) that has been chemically cross-linked to create a network-like structure. It acts like a flexible plastic that can form a protective layer on skin.

This ingredient creates a thin, flexible film on the skin's surface that helps lock in moisture, smooth texture, and improve the longevity and wear-resistance of cosmetic products.
