TOCOPHERYL ACETATE
Tocopheryl acetate is a derivative of vitamin E (α-tocopherol) and is one of the most commonly used antioxidants in cosmetic products. It helps protect the skin from free radicals. Compared to free tocopherol, tocopheryl acetate is significantly more stable when exposed to oxygen, light, and heat, making it particularly suitable for light-sensitive formulations such as sunscreens. Studies show that, in appropriate formulations, tocopheryl acetate can alleviate UV-induced skin reactions such as redness and swelling. Due to its good stability, it is used in many skincare products to support the skin barrier and protect against light-induced skin aging.(1-3)
