Abstract

The invention provides a tyrosinase inhibitor, and whitening blemish balm and a preparation method thereof. The tyrosinase inhibitor comprises an extract of dried roots of pueraria lobata (wild) ohwior pueraria thomsonil Benth, and a mentha haplocalyx Briq extract, based on the total mass of the tyrosinase inhibitor, the addition quantity of the extract of dried roots of pueraria lobata (wild) ohwi or pueraria thomsonil Benth is 0.1-55%, and the addition quantity of the mentha haplocalyx Briq extract is 45-99.9%. The tyrosinase inhibitor disclosed by the invention is excellent in the effect of restraining the activity of tyrosinase, and does not have any side effects on human bodies. Further, the formula of the whitening blemish balm disclosed by the invention is mild, the activity of thetyrosinase can be effectively restrained, and the whitening effect can be achieved.

Description

technical field [0001] The invention relates to a tyrosinase inhibitor, a whitening and repairing cream and a preparation method thereof, belonging to the field of cosmetics. Background technique [0002] Melanin is mainly produced by melanocytes in the basal layer of human skin epidermis, which can reduce the damage of ultraviolet rays to the skin. The content and distribution of melanin determine the color of the skin. However, the abnormal accumulation of melanin in the basal layer will cause hyperpigmentation and cause melasma, freckles, age spots, etc., affecting people's quality of life. With the deepening of research on melanin biosynthesis, researchers found that tyrosinase (tyrosinase) plays an important role in melanin biosynthesis, and it is the main rate-limiting enzyme in the process of converting tyrosine and dopa to melanin. The overexpression of is the main cause of hyperpigmentation. Therefore, inhibiting the activity of tyrosinase can block the biosynthe...
