introduction
vitamin e is an antioxidant that mainly protects the skin from effects of uv rays. when you eat food that is filled with vitamin e the nutrient will pass through the cell membranes of the skin to add to the body's natural defenses.
vitamin e oils are produced from oils like canola, soya or corn directly through distillation. vitamin e oil itself is heavy, thick and has a shelf life of three-years. it the vitamin e oil was exposed to excess heat or air, vitamin e oil can react with oxygen and becomes unusable. therefore, vitamin e oil should always be stored carefully and protected from these elements.
