Prickly Pear Seed Oil is one of the most effective skin nourishing oils. Packed with Vitamin E and essential fatty acids, Prickly Pear oil is a potent antioxidant and free radical scavenger. It has the highest Vitamin E content of all carrier oils including three times that of Argan Oil. Vitamin E, or tocopherols, is a potent antioxidant found in vegetable oils. Antioxidants prevent free radicals from causing cell damage. Skin is susceptible to aging from free radicals because the free radicals damage the collagen (the main component in connective skin tissue) and elastin fibers in the skin. Tocopherols function as free radical scavengers. Vitamin E helps heal, repair, and regenerate skin. Vegetable oils are also a good source of fat-soluble vitamins A, D, and K. As stated above, when tocopherols such as Vitamin E are present in a PUFA-rich vegetable oil, the oil’s lipids become more stable.
