Vitamin E (from Sunflower)
Vitamin E is a complex substance, in that it is composed of eight chemical compounds known as tocopherols that are found in nature. Like Vitamin C, it is a very important ingredient in skin care formulations. It is rich in antioxidants and has many skin benefits, including protection from light-induced damage. Topical application of Vitamin E has been shown to reduce acute and chronic photodamage and skin roughness, the length of facial lines, and the depth of wrinkles. It increases moisturization of the skin and its water-binding capacity, reduces the harmful collagen-destroying enzyme collagenase, which accelerates skin aging. Vitamin E is also a free radical scavenger and an emollient. It has been proven to have antioxidant and anti-inflammatory effects, which help protect and keep skin younger looking.
