Are there any famous dermatology clinics in Gwangju that use LinearG?

I'm a bit of a wimp... lol. I like getting skin care, but I can't stand pain lol. I was looking for a pain-free procedure and got a recommendation for LinearG. Which dermatology clinic in Gwangju is good? It would be even better if the price is reasonable, the staff are friendly, and the clinic is clean!
