Genistein is a super active component of soybean. It has very potent antioxidant abilities and is proven to inhibit UVB-induced redness in human skin.
It is a phytoestrogen (a plant-derived molecule with estrogenic effect) so it is especially 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 genistein might be able to help with that.
Show me some proof
