How effective is toning laser for freckle removal?

I would like to inquire about a consultation for laser treatment for melasma and blemishes.

Recently, I have been very concerned because dark spots and blemishes have increased significantly, especially around my eyes and cheekbones, and my complexion looks dull overall.
Even though I diligently applied sunscreen and vitamin serum and tried home care, the pigmentation that had already formed did not fade.
I am leaving an inquiry to take this opportunity to achieve clear skin through dermatological laser treatment.
Although I need to get an accurate diagnosis of my skin condition, I am curious about the types and characteristics of treatments that are generally effective for treating melasma and blemishes, such as laser toning and pico lasers.
I heard that melasma, in particular, can get darker if irritated incorrectly.
I would like to know the treatment approach to safely lighten pigmentation without side effects.
Usually, to resolve complex pigmentation issues like mine, how many consistent treatment sessions are required to see noticeable whitening effects?
I am also curious about the treatment cycle.
I'm also curious if the procedure interferes with daily life, and if I can resume normal activities immediately just by applying sunscreen properly!
