I would like to know the treatment methods and number of sessions required for melasma treatment based on skin condition.

Hello. I am writing to inquire because I am concerned about the melasma on my face and am considering treatment. Since treatment methods and plans may vary depending on the clinic, I would like to ask a few questions before the consultation. I am curious if, when receiving melasma treatment, you determine the treatment direction by examining the overall condition of the skin rather than simply checking the areas where pigmentation is visible. I would also like to know if the treatment involves repeating a single procedure, or if methods are added or changed depending on the skin's reaction. I am also curious whether the number of treatment sessions is fixed from the start or if it is adjusted as the skin condition is monitored during the course of treatment. Please also advise on any points I should prepare or check in advance for my initial consultation.
