The hop extract helps activate melanocyte cells and, furthermore, it can control Microphthalmia-associated transcription factor (MITF), a gene involved in the activity of melanocyte cells.
Hops (Humulus lupulus) are a perennial climbing vine, a member of the family of Cannabinaceae and, hence, a close relative of Cannabis sativa. Only the female ripened flower is used in cosmetics. There are presently over a hundred varieties of hops cultivated around the world. Some of the best known are: Hallertauer, Fuggles, Tettnanger, East Kent Goldings, Styrian Goldings, Perle, Saaz, and Cascade, to name only a few.
