Use
isoflavones is a family of phytoestrogens related to flavonoids that appear to have an estrogen-like effect. Clinical studies indicate an anti-aging application, given their ability to inhibit the chemical process leading to collagen degradation in the skin. Some sources cite anti-oxidant and anti-inflammatory properties as well. Among commonly used isoflavones are genistein, genistin, glycitein, glycitin, orobol, and prunetin. Soybeans and other soy-derived products are reported as the richest sources of isoflavones, though they are also obtained from red clover.
