Description

technical field [0001] The invention relates to the field of skin care products, in particular to a composition for whitening and lightening spots, a water light liquid containing the composition and a preparation method thereof. Background technique [0002] Sun exposure will lead to skin aging and accelerate skin aging, generally manifested as pigmentation, dark yellow, accelerated formation of melanin and free radicals causing degeneration of skin elastic fibers. The formation process of melanin is as follows: tyrosine in human skin melanocytes is oxidized under the catalysis of tyrosinase to form dopa and dopaquinone, which are further oxidized after rearrangement to form dopachrome, 5,6-di Oxindole, indolequinone, and finally melanin. The main factors affecting the formation of melanin are: the number of melanocytes, the activity of tyrosinase, the content of oxygen free radicals and the content of tyrosine. Among them, tyrosine is an essential amino acid for the huma...
