Is Pico Toning effective?

Has anyone tried Pico Toning? I've been really worried about melasma and blemishes lately, so I was looking into it and heard that Pico Toning is good. I'm curious about the actual effectiveness. I want to know if it simply brightens the skin tone, or if it also noticeably lightens melasma and pigmentation.

I would also like to know if the results are noticeable immediately after the procedure, or if it is the type that gradually improves after multiple sessions. I am also confused about the generally recommended number of sessions and the optimal interval between them. I have heard that there is almost no effect after just one or two sessions.

I am honestly curious about the side effects as well. I am okay with redness, stinging, or peeling, but I am worried about whether there might be more severe side effects or if the pigmentation could become darker. My skin tends to be sensitive, so I am even more concerned.

I've noticed that costs vary significantly from hospital to hospital. I'm curious about the approximate average price per session and whether it's better to sign up for a package. I also want to know if places that are too cheap might be less effective or if there are differences in equipment.

Lastly, looking at reviews from people who have actually received the treatment, I am curious about satisfaction levels and whether consistent treatment definitely makes the skin clearer. I would appreciate your honest opinion on whether this is a procedure you can truly recommend to those concerned about blemishes and melasma.
