The clinical effectiveness of laser melasma removal cannot be generalized as it varies according to each pigmentation. Most of the patients with melasma can improve the symptoms of the disease after receiving laser treatment. Melasma is a kind of yellowish-brown pigmentation spot appearing on the face due to various factors. The etiology of melasma is still unclear, and there are many factors involved in the formation of melasma, among which heredity, sunshine and sex hormone level are important triggering factors. The treatment of melasma is a comprehensive treatment, and the goal of the treatment is to make the pigmentation spots become lighter or disappear, and photoelectric treatment is only a part of melasma treatment. Patients with melasma who have no contraindications to laser treatment can take laser treatment under the guidance of doctors. Through selective photothermal effect, it penetrates into the deep layers of the skin and acts on the melanin of the skin to promote its metabolism and absorption, so as to make melasma lighten or get rid of it. Most of the patients have some degree of improvement in melasma after laser treatment. However, after laser treatment, scientific care is needed to keep the local skin clean and clean to avoid infection; strict sun protection to avoid inducing hyperpigmentation, and so on. Patients who are willing to have chloasma treatment are recommended to consult the dermatology department of regular hospitals, and should combine their own conditions and follow the guidance of specialized doctors to standardize the treatment.
