I'm curious about the effects of Pico Toning! How many sessions do I need?

I had freckles and blemishes on my face that couldn't be covered even with makeup, so I was looking into treatments and found out about Pico Toning.
Do you happen to have any reviews from people who have actually received this treatment, or anyone who knows a good dermatology clinic?
My skin is naturally very sensitive, so I am cautious about getting procedures done carelessly.
I am really curious about how beneficial Pico Toning actually is for improving blemishes, pigmentation, and melasma.
Is the effect much faster and more certain compared to conventional laser toning? I would also like to know how many Pico Toning sessions are usually required to see noticeable changes.
In addition to the effects of Pico Toning, I am also concerned about the extent of side effects or downtime after the procedure.
I am curious if redness or red marks tend to linger for a long time immediately after the procedure, and how much pain there is.
I would also appreciate it if you could let me know how to care for the procedure afterward!
I am also wondering if I need to make sure to apply a regenerating cream separately in addition to sunscreen, and if it is advisable to avoid wearing makeup for a few days after the procedure?
