Copolymer
Copolymer is a synthetic film-forming polymer made by combining two or more different monomers. Makeup and hair products use it to create flexible films, improve wear, add water resistance, and aid pigment dispersion.

Our take
Is Copolymer a Good Ingredient?
Because the generic name doesn't specify the monomers, performance and tolerability vary and are hard to judge. Some film-forming polymers can feel tight, be harder to remove, or occasionally trigger mild irritation in sensitive users. That uncertainty, plus the variable feel, keeps it at Fair rather than Good.

Before you use it
Safety
Generally regarded as safe at typical cosmetic concentrations with low irritation potential. Those with sensitive skin may experience transient dryness or tightness from strong films; remove gently to minimize rubbing. Without a specific INCI, individual allergy assessment is limited.
