Polyester-15

Polyester-15 is a synthetic polymer often used as a film-forming agent and occlusive in cosmetic formulations. It helps to create a barrier on the skin's surface, which can reduce Trans-Epidermal Water Loss (TEWL) and improve hydration. While it may not offer significant direct skin benefits like active ingredients, it can enhance the effectiveness of other hydrating components by minimizing water loss.
