Butterfly spot refers to melasma, which is a symmetrical yellow-brown pigmentation spot on the face. There is a lack of particularly effective treatment for melasma on the face, and it is mainly treated comprehensively through general treatment, drug treatment and physical treatment.
1. General treatment: the appearance of melasma is related to many factors, so it is necessary to actively search for the causes and carry out relevant treatment.

2. Drugs: including topical drugs and systemic drugs.
(1) Topical drugs: hydroquinone and its glycosidic anhydride derivatives are the first-line drugs for chloasma treatment. Commonly used drugs include 2%~5% hydroquinone cream, generally the higher the concentration, the stronger the effect of decoloration, but the greater the stimulation; secondly, 15%~20% azelaic acid cream can also be used for the treatment, but some patients are prone to itching and numbness and other adverse reactions.
(2) systemic drugs: vitamin C and vitamin E, mainly oral-based, for serious patients, large doses of vitamin C can be injected intravenously, which can prevent dopa oxidation and inhibit melanin synthesis.
3. Physical therapy: such as commonly used laser therapy and intense pulse light, which can play a certain therapeutic role in chloasma.
