Soy lipids are high in natural vitamin E (an antioxidant). Antioxidants may help restore damaged tissue and regenerate skin cells. The lipids also allow for rapid hydration and cell regeneration. They are high in lecithin, which is instrumental in skin repair and regeneration. Isoflavones such as genistein and daidzein, the saponins and the natural Vitamin E in soy have been well researched by scientists for their antioxidants and phytoestrogenic properties.
