I recommend Suyeong Shinsegae Dermatology Clinic.

These days, if you go to a dermatologist, most of them specialize in beauty. Here, outpatient treatment is also very thorough, and even though it is a small clinic run by one director, there is no over-prescription.

However, since there are many patients waiting for treatment, you should definitely call and inquire before going and consider the waiting time! Reservations are not accepted.

If there's anyone nearby who needs outpatient treatment, please go there^^
