I'm curious how to determine the treatment cycle for melasma.

Lately, when I look closely at my skin, pigmentation on my cheeks and cheekbones is noticeable, so I am considering looking into alternative methods rather than managing it on my own. I am particularly curious whether this is a one-time treatment or if it requires sessions at regular intervals, so I am looking into the treatment cycle for melasma. I understand that the treatment plan can vary depending on skin condition and the methods used, so I don't think I should judge it based solely on a fixed number of sessions. If I receive a consultation for melasma treatment, I plan to have my current skin condition assessed first and ask about the appropriate intervals and management methods. I am also curious if my skin might become sensitive after treatment and what precautions I should take in my daily life. I have heard that consistent basic care, such as sun protection and moisturizing, is necessary, so I intend to manage both the procedure and my lifestyle habits together. I would appreciate it if those who have actually experienced this could share how often they received treatments and what explanations they were given during their consultations.
