What are the main reasons for skin melasma? Melasma mostly occurs in the cheeks, people and near the forehead, with different sizes and shapes. This kind of light tan spot is smooth and painless, and its color is similar to cooked pig liver. It looks a little black and dirty, which affects the beauty of the face, so it is called liver spot.
Melasma is a kind of hyperpigmentation skin disease that occurs on the face. It is characterized by facial symmetry and butterfly shape, so it is also called butterfly spot. It is characterized by localized light brown or brown patches. The cause of the disease is not very clear. It is generally believed that it is related to endocrine. In addition, it is also related to heredity, sunlight, pregnancy, drugs, etc.
The skin consists of epidermis, dermis and subcutaneous tissue. Epidermis is the outermost layer of skin, which can be divided into basal layer, spinous cell layer, granular layer, transparent layer and cuticle from inside to outside.
The basal layer is the 'mother' layer of the epidermis, which can produce fresh skin cells. It takes 4-6 weeks for these cells to regenerate and divide. While the skin cells metabolize, a certain number of melanocytes are produced and arranged to form the skin color.
If it is because of metabolic disorders, liver and reproductive system diseases caused by skin brown spots, it can not be used indiscriminately. Should ask the doctor after diagnosis, if it is caused by pregnancy chloasma, that is the lack of vitamin C in pregnant women. Vitamin C can reduce melanin and play a 'bleaching' role, which is good for the treatment of butterfly spots.
