What causes melasma?

Chloasma is a common skin disease. The causes of this disease include exogenous and endogenous causes. Although chloasma does not have a significant impact on physical health, this disease has a great impact on the patient's image. This disease brings troubles to many people's lives. So what causes melasma?

What causes melasma?

First of all, we must have a clear understanding of melasma so that we can prescribe the right medicine. Melasma, also known as "butterfly spots", refers to spots distributed in a butterfly shape on the face. According to medical research, as a common hyperpigmented skin disease, the pathogenesis of melasma is very complex. At present, experts believe that the causes of melasma are mainly divided into two types: exogenous causes and endogenous causes.

Among them, ultraviolet radiation, cosmetics and certain topical medications, skin microecological imbalance, inflammatory factors, etc. are exogenous causes of melasma. In addition, the endogenous causes of chloasma mainly include endocrine disorders, genetic factors, gynecological diseases such as the uterus and ovaries, liver and gallbladder diseases, mood swings, etc.

It is worth noting that ultraviolet radiation is the most important factor in the exogenous etiology of melasma. As we all know, ultraviolet rays have a great impact on human skin, which can lead to an increase in pigmentation spots. Therefore, in our daily lives we must pay attention to sun protection measures and avoid ultraviolet radiation to reduce or even eliminate chloasma. In addition, endocrine disorders are the most important endogenous cause of melasma.

If a person suffers from hyperpituitarism and gonadal diseases, there is a high probability of developing melasma. Moreover, women usually cannot avoid developing chloasma when taking or injecting contraceptives. What’s more serious is that once you suffer from melasma, even if you stop using birth control pills, the melasma on your face will not even fade away and will remain unchanged for many years.

Through the above introduction, we have a clearer understanding of the cause of Huangpu Ban. Huangpu Ban has a relatively large impact on the patients' lives. Some suffer from pain and distress due to this disease. Therefore, we must prevent this disease according to the cause of the disease, and patients must relieve the symptoms of this disease in time to avoid the impact of this disease on our lives.
