Which treatment is most effective for blemishes around the cheeks?

Lately, I have been worried because blemishes around my cheeks are very noticeable. I didn't used to care much about them, but over time, it seems like the pigmentation that looks like melasma or freckles has increased one by one. In particular, both cheeks have an uneven, patchy appearance, so I am stressed because even with makeup, they don't cover up cleanly.

I have heard that even within the category of blemishes, the effective treatment varies depending on the cause and type, such as melasma, freckles, age spots, and hyperpigmentation, but I am not sure which procedure I should receive. It seems there are various treatments available, such as laser toning, IPL, and pico laser, and I am curious if there are differences in effectiveness between them.

If anyone has actually treated blemishes around their cheeks, I would like to know what procedures you received and how many sessions were needed to see noticeable changes. I would also like to know if pigmentation can reappear or if the skin becomes sensitive after the procedure. Since I understand that the appropriate procedure may vary depending on skin condition, I would appreciate it if you could let me know what I should check and discuss during a consultation before deciding on a treatment.
