Melasma is difficult to treat but a lot of options are there. First and foremost, you have to follow strict sunprotection. Do not move out of house without sunscreen application 20 mins prior. Creams can be prescribed for melasma. Chemical peels also work a great deal in the initial stages to reduce the pigmentation which can later be maintained with creams.
