Melasma is a common facial hyperpigmentation disorder in which free pigment from the underlying layers of the skin collects in patches. The edges of the diffuse pigment are not clear, and the color is light yellow, dark yellow, and brown. Spots or acne on the face, for many face control, is a bolt from the blue! A good face is tossed to the ground by spots and pimples. Among them, chloasma makes many beautiful women suffer a lot, the skin is dark yellow and colorless, and the beauty is in “crisis”, which is really bad for the emotion and affects the mood, and many people are looking for ways to subdue chloasma. There are many factors causing melasma, and the combination of internal adjustment and external treatment is the most ideal way of treatment at present. What are the causes of chloasma? 1. Imbalance of yin and yang in human body (1) Blood stasis on face due to liver qi stagnation; (2) Spot formation due to weak spleen and stomach, where qi and blood cannot moisturize the face, and dampness and heat rises up to the face; (3) Chloasma due to blood stasis on face due to insufficiency of kidney yang and dispersion of yang qi. (2) Emotions Human emotions will affect the secretion of hormones. When chloasma appears, people’s emotional changes will be more serious, and they may be anxious and disappointed, which will further aggravate the condition of chloasma, so it is very important to keep a happy mood in daily life. Pregnant women are prone to chloasma when they are 3-5 months pregnant, so it is often called “pregnancy spot”. When pregnant, due to the change of hormone level in the body, the metabolism of the body is accelerated, and the dirt on the skin cannot be discharged in time. Moreover, the combined effect of estrogen and progesterone in the body leads to facial pigmentation, stimulates the melanin cells to be active, and increases the production of melanin, and most of the melasma triggered by pregnancy fades away gradually after delivery. 4. Suffering from chronic diseases Most women suffering from reproductive system diseases such as irregular menstruation, dysmenorrhea, uterine adnexitis, infertility, etc. can cause chloasma, which is mainly caused by endocrine disorders. In addition, chronic gastrointestinal diseases, hyperthyroidism, liver disease, tuberculosis, tumors, etc. can also cause chloasma. Therefore, one should actively treat the original disease. 5, sunscreen measures are not done When a large amount of ultraviolet rays directly radiate human skin, in order to avoid skin cells being oxidized, the human body secretes a large amount of melanin to protect it, which leads to the formation of dark spots by pigmentation. UV irradiation can activate tyrosinase activity, increase proliferation and activity of melanocytes, accelerate melanin synthesis, and cause pigmentation on the face. It is suggested that people who are prone to chloasma should minimize going out to the sun or strengthen sun protection, such as holding umbrellas or applying sunscreen, and avoid being exposed to the sun from 10 a.m. to 4 p.m. (especially in summer). Inappropriate use of cosmetics Many low-quality cosmetics contain excessive heavy metals, fragrances and other ingredients, which will accelerate the production of melanin when absorbed by the skin and induce chloasma by ultraviolet radiation. It is recommended that women choose cosmetics with natural or organic ingredients, try to wear light makeup and less heavy makeup, and do facial cleaning in time. 7. Smoking and drinking, staying up late for a long time Smoking and drinking, spending long hours on the computer, reversing work and rest schedules, or not getting enough sleep for a long time can all contribute to the formation of chloasma. Therefore, you should smoke and drink less, avoid being on the computer for a long time and staying up late, and keep enough sleep. Why do we need internal and external treatment to get rid of melasma? Since 70%-80% of melasma is caused by internal factors and 20%-30% is caused by external factors, therefore, the elimination of melasma can not be done only on the face, but internal and external treatment is the king! The cause of chloasma is very complicated, if you want to treat it thoroughly, you must go to a professional spot removal organization to find the cause of the disease and prescribe the right medicine!
