Where to get good acne scar treatment in Seomyeon

I'm an office worker who has a lot of concerns about acne scars. I had a combination treatment with Fraxel MTS 5 years ago and Vivace laser treatment 2 years ago. It was effective at the time, but as time goes by, my pores have gotten bigger and the scars are bothersome. I'm thinking of getting scar treatment again, but I don't know which dermatologist in the Seomyeon area to go to. I don't get acne anymore, but I have a lot of deep scars. Is there a place that does the treatment well?
