Sunflower oil has a balanced and rich nutrients composition. A large amount of Vitamin E and fatty acids (Omega-6 mostly) makes the oil effective for both internal and external usage. Sunflower oil is the source of Vitamin E that acts as an emollient that traps moisture inside skin cells. Therefore, using sunflower oil for the skin helps keep it hydrated for a longer period. Vitamin E in skincare products may help protect the collagen and elastin in the skin and reduce fine lines and wrinkles.
