Why are young and middle-aged women prone to chloasma? Melasma, commonly known as yellow face, is a yellowish-brown patch on the face, the onset of which may be related to pregnancy, oral contraceptives, endocrine disorders, reproductive system diseases, chronic liver disease, and mental factors. The onset of pregnancy is related to the level of progesterone in the body; the onset of oral contraceptives is due to the combined effect of estrogen and progesterone; the cause of non-pregnancy and non-oral contraceptive onset is unknown and may be related to sun exposure, external cosmetics, mental depression and other factors. Chinese medicine believes that chloasma is caused by liver and kidney yin deficiency, liver depression and qi stagnation, loss of harmony between qi and blood, and stagnation of qi and blood on the face. What are the clinical characteristics of chloasma? Chloasma is a common pigmented skin disease that can develop in both men and women, half of which are mostly found in young and middle-aged women. The lesions are often symmetrically distributed on the cheeks, cheeks, back of nose and forehead, and the typical damage is yellow and light brown patches with clear boundaries and irregular shapes. What should I do when melasma appears? After growing melasma, attention should be paid to eliminate the cause as much as possible and give corresponding treatment and treatment to reduce the skin symptoms.

Chinese medicine treatment is mainly based on nourishing liver and kidney, dredging liver and Qi, activating blood circulation and removing blood stasis, which can correct the abnormalities of melanin production and transportation in the body and decompose the excessive deposited melanin in the skin; supplemented with topical drug treatment, one is to destroy the formed melanin, and the other is to nourish and protect the skin.
