Whether skin is white or not mainly depends on the ability of melanocytes to synthesize melanin. Melanocytes are distributed among the cells in the basal layer of human epidermis. The tyrosinamide they contain can oxidize tyrosine into polysaccharides. After a series of metabolic processes, melanin can finally be produced. The more melanin is produced, the darker the skin will be; otherwise, the skin will be fairer.

Research has proven that the activity of tyrosinamide is closely related to copper, iron, zinc and other elements in the body. Regularly eat foods rich in methane and rare elements zinc, copper, and iron, such as animal offal, liver, kidney, crustaceans, clams, crabs, river snails, oysters, aquatic products, mullet roe, and legumes such as soybeans, lentils, and green beans. , adzuki beans, hard-shell fruits such as peanuts, walnuts, black sesame seeds and raisins, etc., have darker skin color.

Vitamin C can interrupt the process of melanin production, prevent the generated dopa ammonia from being further oxidized and reduced to dopa, and can reduce the serum copper oxidase content and affect the activity of tyrosine. This interferes with the biosynthesis of melanin. If you want to make your skin whiter, you might as well eat more foods rich in vitamin C, such as tomatoes, oranges, lemons, hawthorns, citrus, etc. Vitamin C can reduce melanin in the skin, reduce or even remove dark spots and freckles on the skin, and accelerate the restoration and whitening of the skin. At the same time, it is not advisable to drink excessive coffee or coffee that is too strong, otherwise the skin will easily turn dark.

In daily life, if you regularly eat foods rich in essential substances for melanin metabolism, or continuously supplement foods that can enhance the activity of tyrosinase, your skin will tend to be darker. On the contrary, if you regularly consume foods that can interrupt the melanin metabolism process, your skin will tend to be fairer.
