Dermatological and cosmeceutical benefits of Glycine max (soybean) and its active components.

Glycine max, known as the soybean or soya bean, is a species of legume native to East Asia. Soya beans contain many functional components including phenolic acids, flavonoids, isoflavonoids (quercetin, genistein, and daidzein), small proteins (Bowman-Birk inhibitor, soybean trypsin inhibitor) tannins, and proanthocyanidins. Soybean seeds extract and fresh soymilk fractions have been reported to possess the cosmeceutical and dermatological benefits such as anti-inflammatory, collagen stimulating effect, potent anti-oxidant scavenging peroxyl radicals, skin lightening effect and protection against UV radiation. Thus, present review attempts to give a short overview on dermatological and cosmeceutical studies of soybean and its bioactive compounds.
