Glycine Soja (Soybean) Seed Extract description

_Glycine soja_ (Soybean) seed extract is a component of the soybean plant that’s a rich source of antioxidants known as isoflavones. Chief among them are daidzein and genistein, both known as phytoestrogens due to their molecular similarity to estrogen. It’s important to note that phytoestrogen compounds are not hormones and are widely considered safe for topical use. Among other antioxidants found in soybean seeds are quercetin plus syringic, ferulic, and sinapic acids, all of which play role in defending skin from environmental aggressors that hinder its appearance. Some of the antioxidants in soy, particularly genistein and daidzein, have considerable research supporting their benefits for visibly reducing signs of aging due to sun damage as well as the visible consequences of estrogen loss, such as skin becoming thinner and developing a crepe-like texture. These antioxidants are also potent skin soothers and help support skin’s firmness and resiliency. Taken together, the antioxidant components of _Glycine soja_ (soybean) seed extract work in numerous ways to help skin look younger and maintain a healthy, even-toned appearance. _Glycine soja_ (soybean) seed extract has been reviewed and deemed safe as used in cosmetics. Typical usage levels range from 0.09–3%; however, greater amounts are permitted depending on formulary goals.
