I'm curious about the price range for Pico Toning!

Lately, whenever I look in the mirror, I am considering Pico Toning because of the dark spots and freckles appearing on my face.

My skin tone wasn't particularly clear to begin with, but recently, as my outdoor activities have increased significantly, perhaps due to UV rays, around my eyes and on my cheekbones
I'm not sure if they're melasma or freckles, but they popped up really messily.
Even after diligently applying whitening creams or functional cosmetics, the blemishes that had already formed did not fade easily, so I eventually started considering Pico Toning.
When I asked around, many people recommended Pico Toning because it causes minimal skin damage.
I became interested after hearing that there is less concern about pain or side effects, so I am writing this post to ask a question and clarify a few things before deciding on the procedure.

First of all, what are the specific effects of Pico Toning?
I heard that it breaks down melanin pigments into very fine particles and expels them, and usually, you need to receive the treatment a few times for a dull complexion to become noticeably clear.
I am wondering if melasma fades. Also, I would like to know if it provides substantial help with overall tone improvement, pore reduction, and skin texture improvement, in addition to simply treating pigmentation.
I am also curious if there will be enough redness or scabs after the procedure to avoid interfering with daily life.
I am also curious about the approximate price.
I've heard that Pico Toning is usually received in 5- or 10-session packages rather than as a single session.
It would be very helpful for me to set a budget if you could share a rough guideline for the cost of 10 sessions based on dermatology clinics in Seoul or the metropolitan area.
Also, who is Pico Toning recommended for, based on their skin concerns?
In addition to people like me who are worried about suddenly darkened melasma and blemishes,
I would like to know if Pico Toning is effective for people who want to remove red or brown marks left after acne, or a bad tattoo.
My skin is slightly sensitive and prone to redness, so I am worried whether it will cause irritation even for someone with this sensitive skin type.
