Which one is the most effective for melasma?

I'm so stressed every time I look in the mirror because of the dark spots that keep popping up on my face, possibly due to UV rays. I'm looking into starting professional treatment before it gets worse!!

I’ve heard that melasma is usually treated with procedures like Pico Toning or Laser Toning, but I’ve also heard that it is difficult to see noticeable results with just one or two sessions and that consistent treatment is necessary. What is the recommended number of sessions to achieve clear skin? I am wondering if consistent treatment at least 10 times is required to see results.

Also, which laser is the most effective? I would appreciate advice from those who have personally received it regarding the duration of the results and how long the effects last.
