Generally speaking, the skin is naturally black and cannot be changed. Whitening with skin care products will not have much effect. Black and white skin is determined by genetic factors. There are many factors of blackness, and the skin is naturally black, which cannot be changed by external forces. This kind of natural black skin really can't be solved, but it doesn't matter whether it is black or not. Black skin needs work, so does white skin.
The skin is naturally black and not afraid. Usually drink more water, less sunshine, pay attention to prevention, have a light diet, and eat less foods with more melanin, such as carrots and soy sauce. Exercise more at ordinary times, eat more fruits, cut a short piece every day, wash it, peel it off, and wipe the whole body with aloe juice. The skin will naturally turn white. Please look at me confidently! In fact, dark skin is not the key. The key is that clothes are clean and tidy, and there is no smell in your mouth and body. You speak well, you are kind and gentle, and you love to laugh ... You are welcome everywhere!
From the perspective of skin care products, products containing nicotinamide and vc, as well as tranexamic acid and 377 arbutin can be used. The following is my own suggestion on the mask with whitening effect (apply the mask at most three times a week). We all know a rule, tanning in summer, covering in winter, will go back in vain. This is because old melanin will fall off with skin metabolism, but in the same metabolic cycle and the same area, people with natural light skin color will produce less melanin 10 unit than people with natural dark skin color.
