Hop is a plant found across Northern Europe. In popular culture it was known as “devil’s wood” because it climbs trees in an anti-clockwise direction. In the therapeutic field, it is used for its sedative and antiseptic benefits. From hop extract, Clarins Laboratories uses components rich in phytosterols, vitamin D precursors, called unsaponifiables. These are also used for their capacity to stimulate the activity of fibroblasts.
