Inquiry about melasma treatment

Hello. Recently, I have been concerned about dark spots appearing on my cheekbones, possibly due to UV rays and stress. While looking for a dermatologist, I learned about full-scale melasma treatment. I have heard from others that I need to be cautious, as undergoing strong procedures without proper planning could actually darken the pigmentation. I am writing to inquire because I do not fully understand the specific characteristics of how melasma treatment is performed. I have heard that unlike general blemish removal, melasma treatment involves using low-power laser toning to break down melanin pigments into smaller particles to gradually manage the condition. I would appreciate detailed information regarding specific treatment methods tailored to my skin condition, the estimated number of sessions, and costs!
