Xanthohumol
Xanthohumol, a chalcone flavonoid, is one of the chemicals in hops that gives beer its bitterness and flavor. Commercial beers contain less than 0.2 mg of xanthohumol per liter. Here we present a standardized extract from hops, the female inflorescence of Humulus lupulus, that brings the benefits of this natural chemical to your skin. Xanthohumol decreases the concentration of reactive oxygen species, restoring the original concentrations of of enzymatic and nonenzymatic antioxidants after oxidative stress, and lipid peroxidation was attenuated. It is a natural anti-inflammatory and anti-eczema chemical and will help reduce oxidative stress. It is also a phytoestrogen, ideal for use in perimenopause and menopause to protect skin and scalp. Hops are added to beer in part for their preservation power, due to the antibacterial chemicals they contain.
