Many friends think that the whiteness of the skin mainly depends on the congenital genetic skin quality. In fact, this is only partly correct because postnatal diet is even more important. If your diet is not reasonable, it will make your whitening efforts completely ineffective. An unbalanced intake of acidic and alkaline foods can lead to an imbalance in the body's fluids which should be weakly alkaline. When the intake of acidic and alkaline foods is not balanced, blood may tend to be acidic, bringing various discomforts to the human body and promoting the formation of skin pigmentation spots. The formation of eye bags is also related to this. Eating more fresh fruits, edible fungi, and other foods while controlling the intake of strongly acidic foods such as meat, alcohol, and sugar is essential to maintaining a good weakly alkaline state of the body fluids and preventing and fading spots.
