I recommend Lee Hyun Dermatology Clinic in Jaesong-dong, Haeundae-gu, Busan.

A few years ago, when I was in Busan, I received laser freckle removal treatment at Lee Hyun Dermatology. Compared to the flashy, downtown dermatology clinics, the interior and scale were a bit plain, but the director was incredibly kind and thorough, and I was very satisfied. The director personally consulted with me, and she didn't push or pressure me into expensive procedures, but recommended just the amount I needed. I thought I'd need multiple treatments, as others had suggested, but I ended up getting three. I didn't have any spots or blemishes, just freckles, so I had laser treatment on the first day, scabs removed a few days later, and a follow-up check-up the next day. The price was so reasonable that I wondered if the director had anything left. I was so pleased with my clear complexion after the treatment. Now that I don't live in Busan, I highly recommend this clinic. It's so kind, honest, and excellent.
