Soy Isoflavones

What-it-does: antioxidant


The biologically active, phytoestrogenic parts of the soybean. The most well-known one is genistein, a potent antioxidant that is proven to inhibit UV-induced redness in human skin. 

Soy isoflavones are also thought to be useful for situations when natural estrogen levels are low, such as during and after menopause. Low estrogen levels can cause skin thinning and collagen loss and soy isoflavones might be able to help with that. 

Show me some proof
