Our take
Is Polyurethane Film a Good Ingredient?
Rated Good because it provides a cohesive, breathable barrier that supports even coverage and product retention, with typically low irritation. Benefits are practical and mechanical; outcomes depend on wear time and adhesion rather than clinical efficacy.

Safety
Usually well tolerated, but occlusion or adhesive contact in patches can cause temporary redness or discomfort in sensitive skin. Limit wear time if irritation occurs. No specific cosmetic-use restrictions are commonly referenced for typical applications.
