As an antioxidant, vitamin E helps to neutralize free radicals. 
Using vitamin E oil on the skin may reduce free radical damage (including wrinkles) caused by sun exposure, smoking, and alcohol intake. Vitamin E may also reduce the appearance of fine lines by increasing the production of collagen, a substance that keeps the skin elastic; and by aiding the growth and regeneration of skin cells.
To use vitamin E to prevent aging and fine lines, dab the undiluted oil around the eye area or other areas where wrinkles tend to form. You could also mix up an anti-aging mask comprising vitamin E oil and aloe vera gel.
