Polystyrene

What Polystyrene is & what it does

Polystyrene is a synthetic polymer made from styrene monomers, used in cosmetics as a film former, bulking agent, and to adjust texture or opacity. In sunscreens and color products it can help build a uniform film and improve the way a formula spreads and sets on the skin. A notable trait is its ability to form lightweight particles or coatings that influence finish and feel.

What does Polystyrene do in skincare?

Polystyrene is used in cosmetics as a film former and bulking or texture agent. In sunscreens and color products it can help build an even film and adjust how a formula spreads, sets, and looks on the skin. It is a synthetic polymer.

Is Polystyrene safe?

Polystyrene is used in cosmetics in solid polymer form and is generally regarded as safe at the levels found in skincare and color products. It stays on the surface of the skin and is valued for its film-forming and textural role. People with very sensitive skin can patch test products as a precaution.

Is Polystyrene natural or synthetic?

Polystyrene is fully synthetic, made by polymerizing the petrochemical-derived monomer styrene. It is not a plant or animal ingredient but a man-made polymer used to fine-tune a product's texture and finish.
