Fungal Skin & Nail Infection Treatment
Fungal infections such as athlete's foot, ringworm, jock itch and nail fungus are diagnosed with a KOH test and treated with topical or oral antifungals by dermatologists.
Overview
Korea's humid summers make fungal infections common. Testing avoids using steroids on fungal rashes, which can make them worse.

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.
