Polystyrene

Polystyrene is a synthetic polymer often used in cosmetic formulations to enhance the texture and stability of the product. It functions primarily as a film-forming and viscosity-increasing agent, giving products a smooth, spreadable consistency. However, it does not have direct skincare benefits like hydration or anti-aging properties.

key benefits

• Improves product texture and spreadability
