Bakuchiol is a meroterprene (is a chemical compound having a partial terpenoid structure) isolated from the Babchi plant (Psoralea corylifolia). It is an antioxidant, anti-inflammatory, anti-bacterial molecule. It has no structural relation to retinol, however studies have demonstrated it is comparable with retinol in its ability to improve photo-aging (wrinkles, hyperpigmentation) with much better skin tolerance.
