How many sessions are required to see melasma removal effects with Pico Toning, and how long do the results last?

Since starting college, I have tried my best to make sure to apply sunscreen, but

I guess getting freckles is inevitable.

Dark spots are starting to appear under my eyes and on the sides of my cheekbones.

I looked it up and it seems like a lot of people are managing their melasma with Pico Toning.

I want to remove melasma with Pico Toning this time.

I have a few questions, haha.

I understand that Pico Toning is a procedure that breaks down pigments using a laser. Is it possible to treat the delicate skin around the eyes, which is very thin?

When I had laser treatment before, the entire treated area was so itchy.

It was hard holding back the urge to scratch.

Isn't Pico Toning that irritating to the skin?

Also, how many sessions is the basic cycle for seeing results with Pico Toning?

If I get the Pico Toning treatment and manage it well, does the frequency of melasma reappearing decrease significantly?

I'm curious about how long the effect lasts.

How many sessions do you usually purchase in a package for Pico Toning treatments?

Please also let me know what the average cost is.
