Skin Rash Treatment in Seoul: Fast Diagnosis and Relief from a Dermatologist
A new rash can come from allergy, infection, heat, a medicine or a skin condition. A dermatologist identifies the cause on the spot and prescribes treatment that works, often in a single visit.
When should I see a dermatologist for a rash?
See a dermatologist for a rash that lasts more than a week, spreads, blisters, is very itchy or painful, or appears after a new medicine — an accurate diagnosis means the right treatment the first time. Seek urgent care for a rash with fever, facial swelling or breathing difficulty.
Common rashes
What is causing your rash?
Many rashes look alike; the pattern guides diagnosis.
Allergic rash and hives
See allergy rashes.
Contact dermatitis
From products or metals; see contact dermatitis.
Eczema
Dry, itchy, recurring; see eczema.
Heat rash
Small itchy bumps in hot, humid weather.

How it works
Accurate diagnosis, targeted treatment
The dermatologist examines the shape, distribution and timing of the rash. Most rashes are diagnosed clinically; scrapings, swabs or allergy tests are added only when they change treatment.
- Visit: examination and diagnosis
- Same day: prescription treatment
- Days 2–7: rash settles
- If recurring: testing and prevention plan
