I finished dual toning 10 times in Myeongdong and then experienced Pico once in Yeouido. 1. Myeongdong: There are so many people. If you visit after work on a weekday, even if you make a reservation, you have to wait a few hours before going, so I used it a lot as the first time on Saturday. Because it is a factory-type dermatology clinic, several doctors are randomly assigned, but the female doctors were particularly thorough. It was disappointing in terms of blemish removal effect because it wasn't pico toning, but I still think it improved skin tone. I heard there is a pico toning machine. 2. Yeouido: This was my first experience with pico toning and I visited on Saturday. As of Saturday, it feels like there are a fair amount of people, similar to Myeongdong. Parking is free and toning is done meticulously. Personally, I feel similar to Duel No. 10 and Pico No. 1. Pico was not a Picosure machine. Next time, if I have to quit 10 times, I will definitely do it with pico.
