What causes melasma? What causes this disease?

Chloasma brings troubles to some young and middle-aged women. When this disease occurs, yellowish-brown or dark brown patches will appear in the affected area. Usually, this disease does not cause any discomfort symptoms, but this disease has a relatively large impact on the patient's image. So what causes chloasma?

What causes melasma?

1. Environmental factors. With the continuous development of industry, environmental issues have become a major problem that seriously affects people's lives. *The skin is constantly stimulated by the harsh environment. When our skin cannot metabolize harmful substances all at once, some residues will accumulate on the surface of the skin, which will form chloasma over time. Therefore, environmental pollution is one of the main culprits causing melasma.

2. Pregnancy and contraceptive factors. Some female friends develop chloasma on their foreheads during pregnancy. This is because pregnancy causes an imbalance in hormone levels and endocrine abnormalities in the body. Chloasma caused by pregnancy generally gradually improves after delivery. In addition, oral contraceptives can also cause the appearance of melasma, because contraceptives contain a large amount of estrogen, which can change the hormone level of the body and cause melasma. Therefore, we would like to remind all female friends that if chloasma occurs after taking oral contraceptives, they should stop taking the medication immediately.

3. Daylight factor. Sunlight is one of the main causes of many skin diseases, including melasma. Because ultraviolet rays are particularly harmful to the skin, they can directly lead to melanin precipitation, thus causing disease.

In addition to the causes of chloasma mentioned above, there are many other reasons, such as improper use of cosmetics, or the use of counterfeit and inferior products. Melasma is often distributed in various parts of the face, so the forehead is one of the distribution sites. In addition, there is no need to worry if chloasma appears on the face. As long as the cause is identified and symptomatic treatment is given, it can be cured.

Through the above introduction, we have a clearer understanding of the cause of chloasma. Although this disease does not cause obvious harm to our physical health, it has a relatively large impact on our image. We must pay attention to the prevention of this disease to prevent it from affecting our lives.
