I recommend Haeundae Seoul Dermatology Clinic.

This is Seoul Dermatology Clinic, located in Haeundae Marina Center. Many people in Busan will likely be visiting this clinic. I also went there after a friend recommended it, and surprisingly, everyone in my area knows about it. That's how famous it is for dermatological care.

The wait is really long on weekends. However, for skin care, I highly recommend this place. I highly recommend it to anyone looking for a dermatology clinic in Haeundae.
