Inquiry about the duration of effects and possibility of recurrence after laser treatment for freckles

I'm feeling depressed because my skin looks dull and dirty due to the freckles that have spread widely on my face. Since it's difficult to treat freckles with home care, I'm considering professional freckle laser treatment.
I'd like to inquire about the laser treatment for freckles you offer. I've heard that freckles are a sensitive pigmentation condition with a high recurrence rate, so post-treatment care is very important.

I understand that Maypure uses effective laser equipment to treat melasma. How long does clear skin typically last after undergoing laser treatments like laser toning or pico laser?

Also, I would like to know if, even with diligent care, freckles can reappear in the same spot they were in before, and if so, what causes them and how to manage them to minimize their recurrence.

In addition to things to watch out for after the procedure (e.g., sun protection, use of regenerative cream), if there are any long-term treatments (e.g., whitening treatments, skin boosters, etc.) that would be good to use in parallel to prevent the recurrence of freckles, please recommend them as well.
