Whether the skin is white or not mainly depends on the ability of melanocytes to synthesize melanin. Melanocytes are distributed in the basic cells of human epidermis. Tyrosine contained in melanocytes can oxidize tyrosine into polysaccharides, and then through a series of metabolic processes, melanin can finally be produced. The more melanin is produced, the darker the skin is; On the contrary, the whiter the skin. Black and white skin depends entirely on diet, as the saying goes, "one white covers three ugliness." Women with fair and delicate skin usually get more love, so no matter what healthy skin color and chocolate makeup are popular, there are always a group of diehard "white is beautiful" and resolutely grab "white"! The following Chinese medicine prescriptions have the effect of beauty beauty, and you can slowly adjust your skin color according to your different needs for "white". 1, you should eat less food containing tyrosine, such as potatoes and sweet potatoes. 2, eat more foods containing vitamin C, such as jujube. Fresh dates, tomatoes, oranges, fresh green leafy vegetables, etc. 3. Foods rich in vitamin E include Chinese cabbage, cauliflower, sesame oil, sesame seeds, sunflower seeds and rapeseed oil. In addition to the above dietary precautions, MM can also pay more attention according to the following statement: (1) The most important thing to pay attention to is sunshine. We know that sunlight can darken the skin. The skin will turn black after going out. Whether it is cloudy or rainy, staying outside for a long time (in the open air) will make your skin black, or because there are ultraviolet rays in the sun. On cloudy or rainy days, although the delamination blocks the sunlight, the ultraviolet rays are destroyed by the A-section (long wave) line. Protective measures should be taken when going out, such as wearing a hat, umbrella, sunglasses or applying sunscreen. 10 the morning to 3 pm is the most stressful time of the day. Try to avoid going out in the sun during this time, even if it is cloudy or rainy. When there is sunshine, you can still distinguish the ultraviolet radiation range, which is easy to avoid. You can't see where there is ultraviolet light on cloudy days, which often makes people ignore the effect. Therefore, we should pay attention to avoid purple operation on the skin during the day. (2) Food has a great influence on the skin. Eating more fruits and vegetables, especially foods containing vitamin C, is good for skin whitening, such as tomatoes, strawberries and peaches.
