Soymilk has whitening effect. After all, soybean milk contains a lot of plant protein, soybean isoflavones, vitamins and other ingredients, which can not only regulate human hormones, but also whiten and moisturize skin, so after drinking for a period of time, the skin may turn white.
In addition, the reason why the skin turns black is because melanin is secreted too much, and there is linoleic acid in soybean milk, which can organize the production of transaminase. After this substance is reduced, the formation of melanin will be hindered and it can play a certain whitening role.
For women with yellow and dark skin, if they can insist on eating soy milk correctly, their skin may turn white after a few months, or the firmness will be greatly improved, but it will not change 100%. It still depends on everyone's skin condition.
