Female friends have some understanding of chloasma. Chloasma has also troubled many female friends in recent years. In order to help everyone get the correct treatment, it is necessary to know more about the main causes of chloasma so that the correct treatment can be carried out according to the cause. So what is the main cause of chloasma?

What are the main causes of melasma?

1. Imbalance of yin and yang in the body. One reason is liver qi stagnation, which causes blood stasis on the face. The second reason is spleen and stomach weakness, which causes qi and blood to be unable to moisturize the face, and damp heat rises to the face to form spots. The third reason is kidney yang deficiency, which causes yang qi to diffuse and blood stasis on the face to form male chloasma.

2. Some chronic diseases such as chronic hepatitis and tuberculosis will lead to increased tyrosinase activity and increased melanin production, while the body's own ability to eliminate melanin will be weakened. Once melanin cannot be excreted from the body in time, male chloasma will occur on the face over time.

3. Chloasma is caused by the obstruction of the microcirculation between tissue cells, cell dissolution and death, and the increase of melanin to form pigmentation. The epidermis of the face is the thinnest, with the most abundant capillaries and the easiest to form pigmentation. The pigmentation area is mainly in the basal layer of the epidermis, and the melanin particles increase significantly. In more serious cases, there is also more melanin in the melanophages in the dermis. Compared with normal, the number of pigment cells, melanin formation and the activity of melanin particles have different increases.

4. Chloasma appears on men’s faces due to the influence of female hormones. Just like the reason why women have androgen in their bodies, men also secrete estrogen, but these two hormones maintain a relative balance to avoid the development of chloasma. According to experts, the proportion of sex hormones in a man's body is 87.5% testosterone and 12.5% ​​estrogen. If the secretion of these two hormones is unbalanced, male chloasma will also occur.
