Our skin suffers daily from oxidative stress (action of active oxygen radicals). UV rays, pollution, smoking and internal stress are principal factors in creating them. These free radicals are highly reactive and toxic and can start a chain reaction under the skin's surface, inducing skin damage. Antioxidants are compounds, which neutralize the free radicals using different mechanisms.

The best-known natural antioxidants are vitamin C, vitamin E, beta- carotene and selenium. Scientific studies have shown that topical vitamin C, decrease the number of abnormal sun burn cells and reduce UV damage to DNA. As vitamin C protect the aqueous environment of the skin, vitamin E protects membranes from lipid (fatty acids) peroxidation being the first to absorb the free radicals. Selenium activates two key enzymes, which have an important antioxidant role in the cells, protecting and repairing DNA. The carotenoids are well known by their role in prevention and cancer treatment.

The researches have shown that when these antioxidants are applied topically, their level in the epidermis and dermis is substantially increase thereby not only protecting the skin from acute and chronic photodamage, but also reversing the skins manifestations of photoageing. Vitamins E and C, beta-carotene as well as selenium, are the principal micronutrient antioxidants that have been studied for their efficacy on reduction of oxidative stress and for their potential roles in the prevention of chronic diseases such as cancer, cardiovascular diseases and other disorders.

Sea Buckthorn oil is a very rich and good source of natural antioxidants. The benefit of Sea buckthorn for skin protection/healing is enormous. It is the only plant known so far which contains a large variety of antioxidants such as vitamin E and other vitamin E derivatives, vitamin C, beta-carotene and other carotenes such as lycopene, and selenium.
