PEG-Crosspolymer

PEG-Crosspolymer is a synthetic polymer derived from polyethylene glycol (PEG). It functions as a film former, meaning it creates a thin, continuous layer across the skin's surface when applied in a skincare product.This ingredient is used in cosmetics primarily for its ability to smooth the skin's texture and create a refined appearance. It works by depositing on the skin rather than penetrating deeply, making it a surface-level treatment ingredient.

PEG-Crosspolymer works by depositing on the skin's surface where it forms a flexible, continuous film. This film sits atop the epidermis and can temporarily smooth micro-irregularities in the skin's topography, creating a visually refined appearance.The polymer's crosslinked structure allows it to adhere to skin whilst remaining flexible enough not to crack or feel uncomfortable. However, this effect is cosmetic and temporary—it does not alter the skin's underlying structure or biology.

PEG-Crosspolymer is typically found in finished skincare products rather than used as a standalone ingredient. Apply products containing it to clean, dry skin as directed on the packaging. The smoothing effect is most noticeable on clean skin and will diminish with cleansing, so reapplication may be needed throughout the day if a sustained effect is desired.

PEG-Crosspolymer is generally well-tolerated by most skin types. It is non-occlusive at the concentrations used in skincare and unlikely to cause irritation, though individual sensitivity is always possible.
