Many Korean “skin clinics” focus on cosmetic procedures and may not treat skin disease. Board-certified dermatologists (피부과 전문의) are trained to diagnose and treat it, and medical dermatology is partly covered by Korea’s National Health Insurance. This page is general information, not medical advice.
