I'm thinking of getting Pico Toning treatment near Hongdae, and I'm wondering about the recommended number of sessions!

Hello! I am an office worker concerned because blemishes and melasma on my face are becoming increasingly noticeable as I spend more time outdoors. Since there is a limit to how much I can cover them up with makeup, I was considering dermatological procedures and learned about Pico Toning. Due to my commute, I plan to visit a clinic in the Hongdae area. I would like to know the recommended number of Pico Toning sessions for melasma treatment. I also want to know if I can feel an improvement in my complexion after just one session. Additionally, I am asking if the side effects of redness or scabbing after Pico Toning will be noticeable when I go to work. I would appreciate kind advice from those with experience regarding the cost and how long the effects last after a full treatment!
