Chloasma can be lightened or eliminated by general treatment, medication and physical therapy. 1. General treatment: avoiding triggering factors and adjusting life style, such as taking sun protection measures in daily life, avoiding the use of photosensitive drugs, paying attention to rest, ensuring sufficient sleep time and consuming more vitamin-rich food, which can have a positive effect on the lightening of chloasma. 2. Medication: you can choose to use hydroquinone and its glycoside derivatives, azelaic acid, vitamin A cream, etc., and take vitamin C tablets, glutathione tablets and other medicines orally under the guidance of professional doctors. 3. Physical therapy: If the effect of general treatment and medication is not obvious, physical methods such as laser and intense pulsed light can be used. In the use of medication, should follow the doctor’s instructions to standardize the use of drugs, not blindly use drugs or change the dosage without authorization, in order to avoid adverse reactions.
