Chronic Itch (Pruritus)
Chronic itch lasting more than six weeks can come from skin disease, dry skin, nerve problems or internal conditions such as kidney or liver disease. Dermatologists find the cause and treat with moisturisers, anti-inflammatories, phototherapy or newer targeted medicines.
Overview
Itch in older adults is common in Korea's dry winters, but persistent itch without a rash needs a medical work-up.

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.
