What is melasma? Why does melasma occur more in women than in men?
Melasma is a condition in which brown patches appear on the skin due to an increase in the pigment melanin. Melasma is more common in women than men.
1. What is melasma?
Melanin, also known as melanin, is the factor that determines the color of each person's skin. According to studies, melanin is an effective light absorber (can dissipate more than 99.9% of absorbed UV rays), plays the role of sunscreen and protects the skin from UV rays.
However, if too much is produced, this pigment will accumulate, concentrated in a certain area on the skin. This phenomenon is called melasma.
In women, melasma areas often appear on the cheeks, nose, chin or forehead. Melasma in women causes a loss of aesthetics for the skin, which makes many women afraid and lack confidence in life.

There are many causes of skin pigmentation, of which the main 4 causes can be mentioned as follows:
2.1 Sunshine
The sun is the leading cause of negative effects on the body including melasma.
When the sun is in direct contact with the skin, it will lead to an abnormal amount of melanin. This is what causes the spots to form and spread. In addition, UV rays in the sun also destroy cells, break down the structure under the skin, causing dry skin, aging and even skin cancer.
2.2 Heredity
In addition to sun exposure, genetic factors can also cause melasma. According to scientific studies, about 30% of people with melasma are determined by genetic factors
2.3 Hormones
Hormonal disorders cause the amount of melanin pigment in the body to increase rapidly, causing melasma. This is the answer to about 50-70% of pregnant women with melasma.
In addition, in stages such as puberty, menopause or using oral contraceptives are also the causes of skin pigmentation. Usually, hormonal melasma can be easier to overcome, because when the body is stable. hormonal regulation, melasma will disappear on its own.
