Argan Oil contains high levels of essential fatty acids, including linoleic acid. Fatty acids are beneficial for nourishment, protection and repair of the skin, nails and hair. Argan is also very high in Vitamin E, one of the most powerful biological anti-oxidants in neutralizing free radical production. Vitamin E is also very potent at stabilizing the cell membranes through a process called lipid peroxidation. Therefore, it is excellent at slowing the aging process of the skin.
