Soy isoflavones are derived from soy and help keep skin young looking. Epidemiological studies have demonstrated that diets rich in soy products, as they are in Asian countries, are closely linked to lower incidences of breast cancer and cancer of the uterus, cardiovascular disease and postmenopausal symptoms. It is now generally accepted that such properties are due to isoflavones, a class of plant compounds that is particularly abundant in soybeans. Isoflavones interfere with cell metabolism. In the skin, they’ve been shown to stimulate the production of the skin’s structural components (collagens) and to inhibit matrix metallo-proteinases (enzymes that degrade the underlying network of proteins that make up the skin’s support layer).
Phytohormones from soybeans
Soy isoflavones found in skin care products are in a pure and physiologically active form called aglycone. They are composed of pure genistein (an isoflavone that acts as an antioxidant to counter the damaging effects of free radicals in tissues). Isoflavones aglycones are known to exert a hormone-like effect in postmenopausal skin, but without the drawbacks of hormone therapy. To penetrate deeper skin layers (the dermis), isoflavones have been incorporated into a liposomal preparation. In the dermis, the isoflavones boost collagen and elastin production, which leads to increased skin density and improved firmness and elasticity.
