Chloasma generally cannot be removed completely. Depending on the situation of each person, it can be improved by applying drugs externally and phototherapy. 1. Medication: Apply appropriate amount of vitamin E and hydroquinone cream evenly on the surface of chloasma, massage it to make the skin absorb it completely, and insist on it for a long time to promote the formation of melanin and improve the effect of chloasma. Oral tranexamic acid, vitamin E and other drugs can also be taken to improve. 2. Photoelectricity treatment: common photorejuvenation, picoseconds, etc., is the use of specific broad-spectrum color light irradiation to the surface of melasma, which can penetrate deep into the dermis layer, decompose the pigment, promote the proliferation of new collagen, and allow the decomposed pigment to be discharged along with the metabolism of the skin, so that the melasma effect can be improved. Improper use of chloasma treatment measures will lead to anti-blackness or aggravation of the situation. Those who are willing to be treated are recommended to go to regular medical institutions for consultation and standardize the treatment and medication under the guidance of specialists, and should not blindly treat on their own to avoid adverse effects.
