2. Lack of trace metal elements in the blood will reduce the activity of tyrosinase in the body, affect the synthesis and metabolism of melanin and cause pathological changes. Eating more foods rich in iron, zinc, copper and other metal elements can enhance tyrosinase activity and accelerate melanin synthesis.
For example: meat (beef, rabbit meat, lean pork), animal liver, eggs (eggs, duck eggs, quail eggs), milk (milk, yogurt), vegetables (fresh vegetables, radish, eggplant, winter bamboo shoots, fungus, kelp and so on. ), beans (soybeans, peas, mung beans, bean products), peanuts, black sesame seeds, etc.
3. Estrogen can enhance the oxidation of tyrosinase and increase melanin. Changes in mental state such as anger and excessive internal heat can cause parasympathetic nerve excitement, increase the secretion of melanocyte-stimulating hormone by pituitary gland, stimulate the activity of melanocytes, and increase melanin.
Extended data
Vitamin C and light can inhibit tyrosinase activity.
Because vitamin C can reduce the levels of serum copper and serum copper oxidase, affect the activity of tyrosinase and interfere with the synthesis of skin melanin. Patients with cherry vitiligo should not eat more. Cherry is rich in vitamin C, which can interrupt the production of melanin and aggravate the condition of vitiligo during the metabolism of melanin.
Melanin is the most important determinant of skin color. If there is more melanin in the skin, the skin will be black, and if there is less melanin, the skin will be white. The amount of melanin is mainly determined by the intensity of tyrosinase activity in melanocytes. The stronger the tyrosinase activity, the more melanin is synthesized. The color of the skin surface will also change after the light is scattered on the skin with different thickness.
