Vitamin E ( tocopherol) is a lipid-soluble antioxidant. Ultraviolet radiation (UV) causes skin aging by producing free radicals, reactive oxygen species (ROS), which interfere in collagen synthesis, degrade collagen and elastin, and damages lipid component of membranes leading to more water loss and more inflammation.

Studies show that antioxidants can slow down and even reverse these oxidative damages. As an antioxidant, vitamin E suppresses chain initiation and/or chain propagation steps by donating its 6-phenolic hydrogen to the oxygen radicals.

Vitamin E is synthesized by plants and must be obtained from plant-based oils, seeds, fruits and vegetables as dietary sources. Our tocopherol is derived from plants.
