Are there any points to check before inquiring about melasma treatment prices?

As the pigmentation on my face has started to become more noticeable, I am looking into ways to manage it. At first, I thought I could just cover it up with makeup, but as time passed, my skin tone began to look patchy, leading me to consider consulting about melasma treatment. I realized that rather than just comparing prices, I need to check how the treatment is performed and whether the plan varies based on my individual skin condition. I am looking into the number of sessions, intervals, and aftercare methods involved in the treatment process. Since skin conditions and pigmentation levels can differ even for the same concern, I think it is necessary to get a direct consultation rather than deciding based solely on others' experiences. I am also curious about whether aftercare is included when looking into melasma treatment costs and what additional factors I should check. For those who have actually received consultations, I would appreciate it if you could share what specific details you checked besides the price, so I can use it as a reference.
