Chloasma, also known as liver spots and butterfly spots, is a common acquired hyperpigmented skin disease that occurs on the face, mostly manifesting as symmetrical yellow-brown or light black pigmentation. Its occurrence is related to endocrine hormone metabolism abnormalities such as pregnancy, oral contraceptives, menstrual disorders, etc. In addition, drugs, cosmetics, ultraviolet rays, nutrition and other factors may also affect its occurrence and development. Chloasma occurs in young and middle-aged women, not only affects their appearance, but also most patients have different degrees of menstrual disorders, insomnia, irritability and other endocrine and phytoconstitutional disorders, which bring many mental and life troubles and pains to patients. However, although there are many treatment methods for melasma, including oral and external application of various Chinese and Western medicine drugs, all these drugs require half a year or even longer treatment, and many patients cannot persist and finally give up. Although some drugs can achieve certain effect, many patients have more serious skin damage and pigment rebound phenomenon instead of using them properly. First of all, we should find the cause of the disease and take corresponding preventive measures. Don’t expose yourself to the sun for a long time, wear a sun hat or umbrella when you go out, and apply sunscreen on exposed parts when you go out. Prevent all kinds of ionizing radiation, including various glass-shell displays, various fluorescent lamps, X-ray machines, ultraviolet irradiators and so on. All these undesirable stimuli can produce similar consequences as strong sunlight exposure, and even greater damage than sunlight exposure, which results in the aggravation of pigmentation. Don’t listen to those quick-impact advertisements in the market, and stay alert to some pure natural cosmetics. If you suspect that melasma is caused by certain drugs and cosmetics, you should stop using them and observe whether there is any aggravation of melasma, and it is better to find the specific ingredient that causes melasma, so that you can avoid using drugs and cosmetics containing this ingredient in the future. Secondly, we should do individualized medical treatment as much as possible and not to blindly follow other people’s treatment methods. It is best to ask a professional dermatologist to examine melasma patients with different onset causes and then determine the treatment plan according to the specific conditions of each individual. Patients with darker pigmentation should generally use topical depigmentation drugs, such as hydroquinone cream, azelaic acid cream, arbutin, etc. However, all these topical drugs may have different degrees of irritation, so they must be used under the guidance of doctors; oral vitamin C and vitamin E, and large doses of vitamin C can also be tried for intravenous injection. Patients with endocrine disorder symptoms such as irregular menstruation should take oral Chinese medicine for regulation and treatment. Chinese medicine believes that sallow spots are caused by kidney deficiency or Qi and blood imbalance or stasis, so the treatment is to nourish Yin, tonify the kidney, harmonize Qi and blood, activate blood and remove blood stasis, and according to the specific conditions of different patients, the treatment process is usually longer. Be sure to be cautious with freezing, ionization, strong acid and strong alkali and other corrosive substances, otherwise it is easy to cause disfigurement! Patients with more stubborn or recurrent melasma can choose the new modern laser for treatment. The rapid development of modern laser technology has provided a very ideal treatment method for melasma, and we now apply C3 and C6 lasers to treat melasma not only with fast results, but also very safely. The laser uses a high intensity beam of light with a specific wavelength that is absorbed by the pigments in the skin, breaking up the pigments deposited in the skin in a nanosecond (10-9 seconds). Since the laser has a very short duration of action, the heat generated does not spread to the surrounding area and therefore does not cause thermal damage to the surrounding normal tissues, and no scarring is formed. As the pigment particles are gradually absorbed by the body, the color will fade and finally disappear completely after several treatments. Laser treatment for melasma usually takes several times, depending on the condition, the treatment interval can be 1 to 2 times a week or 2 to 3 weeks. You can work normally within 1 hour after each treatment. The treatment process is safe, painless, and does not leave scars, and can quickly “move away” the melasma. It is the most ideal method to treat melasma, and it is combined with the internal treatment of Chinese herbal medicine to consolidate the treatment effect without recurrence. In addition, it is also necessary to pay attention to comprehensive conditioning in life. Quit bad habits, such as smoking, drinking, staying up late, etc. You should pay attention to drinking more water and eating more fresh fruits and vegetables: such as celery, spinach, yellow cabbage, black fungus, lotus root, apple, pear, watermelon, etc. Avoid stimulating foods, especially coffee, cola, strong tea, cigarettes, alcohol, etc., to avoid aggravating the disease. Pay attention to rest and ensure sufficient sleep. Keep a good mood and exercise more, but pay attention to the combination of work and rest. Through effective prevention, medication and laser treatment, supplemented by comprehensive conditioning, melasma treatment has been able to achieve good results now.
