Melasma removal methods include general treatment, drug treatment and physical treatment. 1. General treatment: If chloasma appears on the skin, first of all, it is necessary to avoid triggering factors, especially sun protection, and wear masks, sunglasses and umbrellas on daily trips. In addition, it is also necessary to maintain a good state of mind and combine work and rest. 2. Medication: patients can apply azelaic acid to treat chloasma, which can help reduce the color of chloasma. In addition, hydroquinone, deoxyarbutin and other drugs can also be used externally to help melasma subside. 3. Physical therapy: Melasma can also be improved by laser treatment, including Q laser, intense pulsed light and fractional laser. There are many ways to remove melasma, so it is recommended that patients go to regular hospitals and cooperate with doctors for standardized treatment.
