Melasma laser treatment is useful. Melasma is a kind of skin pigmentation spot appearing on the face. The main symptom is yellowish-brown pigmentation spot appearing on the face with symmetrical distribution, aggravated by sunlight exposure and persisting, which may be related to sun exposure, heredity, change of sex hormone level and so on. Using its selective photothermal effect, laser treatment is able to penetrate into the deep layers of the skin and selectively act on melanin of the skin, thus decomposing the pigmentation spots, which are subsequently phagocytosed and decomposed by macrophages, so as to make chloasma fade away or disappear. Melasma patients must pay attention to sun protection in their daily life. Sun protection not only refers to purely applying sunscreen, but also with physical sun protection measures such as sunglasses, umbrellas, sun hats, and so on, so as to avoid aggravation or recurrence of the condition by exposure to the sun. The choice of chloasma treatment should be made under the guidance of doctors, and should not be done blindly, so as not to cause recurrence and aggravation of symptoms.
