White is not white, depends mainly on the ability of melanin synthesis in melanoma cells. In the basal layer of epidermis cell room, distribution of melanoma cells, it can contain tyrosinase oxidation of tyrosine to shows, after a series of metabolic process of the Middle, and eventually to produce melanin. Generate much melanin, the more dark skin; otherwise, the more white skin.

Studies have shown that activity of tyrosinase and elements such as copper, iron, zinc in the body are closely related. Often eating tyrosine and rare elements zinc, copper, iron-rich foods such as organ meats liver, kidney, crustaceans River clam, crab, snails, oysters, mullet aquatic products, beans soybeans, lentils, the green beans, red bean, nut type of black sesame and peanuts, walnuts, raisins, skin color is darker. In addition, excessive drinking coffee or coffee is too strong, the skin is also easy to turn black.

Vitamin c can interrupt melanoma generated of process, can block has generated of more BA ammonia further oxidation and was restore for more BA, and can reduce serum copper oxidation enzyme content, effect tyrosine enzyme of activity, thus interference melanoma of biological synthesis, if wanted to makes skin white Shi, may wish to more eat some rich vitamin c of food, as tomatoes, and orange, and lemon, and Hawthorn, and citrus Orange,. Vitamin c can reduce melanin pigmentation of the skin, slacken and remove skin spots and freckles, accelerating skin restored to white.

In daily life, if you often eat food rich in melanin metabolism essential substances, or continue to supplement food that can enhance the activity of tyrosinase, skin color tends to be more of a dark complexion. Conversely, if often can interrupt the melanin metabolism process food ingestion, skin tends to be more fair.
