I'm planning to get Pico Toning treatment near Hongdae. Does it improve pigmentation well?

Since returning from summer vacation, perhaps due to strong sunlight, the freckles and blemishes on my cheeks and cheekbones have become patchy and dark. Every time I look in the mirror, my bare face looks so dull, so I have booked a Pico Toning consultation at Maypure in Hongdae, which is convenient for me to visit on my way home from work. My skin barrier is very thin and it is a sensitive type that gets red easily, so I am a little worried about whether the Pico Toning laser will work well for my skin without irritation. I am wondering if consistently receiving a Pico Toning package for about 10 sessions usually leads to a noticeable improvement in skin tone and lightening of pigmentation. It would be a great help if those of you who have received Pico Toning could share vivid reviews regarding the downtime and the level of pain. !
