Polyester-8

What Polyester-8 is & what it does

A film-forming photostabilizer (Polycrylene) that protects UV filters from degrading in sunlight and improves water resistance. It helps sunscreens hold their protection longer.

What does Polyester-8 do in skincare?

Polyester-8 is a synthetic film-forming polymer commonly used in sunscreens and cosmetics. It helps create a smooth, even layer on the skin and can improve how well a product spreads and stays put, including water resistance in some sunscreen formulas. It is mainly a texture and performance ingredient rather than an active.

Is Polyester-8 safe?

Polyester-8 is generally considered safe as used in cosmetic formulas, where it appears at low levels and stays on the skin's surface. As with any ingredient, individual sensitivities are possible. If you have specific concerns, it is best to consult a qualified professional.

Is Polyester-8 natural or synthetic?

Polyester-8 is a synthetic ingredient, a polyester polymer made through controlled chemical processes. It is not plant-derived or naturally occurring. Synthetic polymers like this are often chosen for consistent, reliable film-forming performance.
