Red jasmine rice bran extract for the prevention of the blue light induced photodamges

Blue light protection is one of the hottest topics in sun care categories recently due to blue light would result in skin photodamages such as oxidative stress, pigmentation and photoaging. In this research, a blue light induced cellular injury model was constructed and the blue light exposure could indeed lead to ROS accumulation in HaCat cells, melanin secretion enhancement in the B16 cells and COL1A1 gene expression reduction in the HFF cells. Red jesmine rice bran extract was previously studied to have good UV protection benefit. In this study its blue light protection benefits were further investigated. Red jesmine rice bran extract can prevent the cellular damages caused by the blue light based on the blue light induced cellular injury model including preventing the ROS accumulation in HaCat cells, inhibiting the melanin secretion in the B16 cells and enhancing the COL1A1 gene expression in the HFF cells. Red jesmine rice bran extract could be potentially applied in sun care products to prevent the blue light induced photodamages.
