What is the reason for the black forehead?

1 Kidney Deficiency According to the theory of five elements correspondence, black corresponds to kidney, and black forehead is mostly related to kidney.

If it is light black, it is mostly caused by kidney-yang deficiency, and eat more isothermal foods such as mutton and leeks. If the face is dull and dry, like lacquer wood, it is mostly because of kidney yin deficiency or serious loss of kidney essence. Eat more lotus seeds, medlar and American ginseng.

There is too much waste keratin, too much oil around the forehead and nose, and the keratin metabolism is fast. If the waste keratin is not cleaned in time, the skin in these parts will be darker than other parts of the face.

Regular exfoliation and regular application of hydrating mask can improve the problem of exuberant oil secretion and keratin waste.

3 the forehead left by perennial acne is very prone to acne. If acne recurs, some people like to squeeze acne by hand, and it is easy to leave ugly black acne marks on their foreheads. These acne marks are also one of the reasons why the forehead looks darker.

Compared with other parts of the face, the forehead tanned by the sun belongs to a higher altitude area. In the absence of sun protection measures, it is suntanned first, so after sunbathing many times, you will find that your forehead skin is darker.
