What causes acne scars and rough texture?
Acne scars form when deep inflammation damages the skin's collagen. As the skin heals, it may leave depressed scars, uneven texture or enlarged pores. Rolling scars have soft, wavy edges; boxcar scars have sharper edges; icepick scars are narrow and deep. Post-acne redness and brown marks are not true scars but can also make skin look uneven. Each type responds best to a different treatment, so a doctor's assessment is the first step.
What is Gangnam like for acne scar treatments?
Gangnam has a very large number of dermatology clinics, and many treat acne scars with several devices. Doctors often combine fractional lasers, RF microneedling, subcision, which releases scar tissue under the skin, and skin boosters to rebuild collagen. Because many clinics treat international patients, they are used to planning intensive sessions within a short trip and giving clear aftercare in English.
What is Hongdae like for acne and texture care?
Hongdae, around Hongik University, is a lively area popular with students and younger travellers. Skin clinics here often focus on active acne, pores, oil control and gentle texture treatments, and many offer lasers and skin boosters. It is easy to reach from Incheon Airport by the Airport Railroad. Clinic choice for advanced scar plans is smaller than in Gangnam, so ask about devices and the doctor's experience.

Which treatments work for acne scars?
- Fractional lasers: create tiny treatment columns that trigger collagen remodelling.
- RF microneedling: combines needles with radiofrequency heat to tighten and smooth scars.
- Subcision: releases bands that pull rolling scars down.
- Skin boosters: such as Rejuran or Juvelook, to support repair and skin quality.
- Vascular or toning lasers: for post-acne redness and marks.
How many sessions do you need?
Acne scars usually improve gradually. Many plans include three to five sessions about four weeks apart, though the right number depends on scar depth and type. If you can only visit once, a doctor may combine treatments in one session and suggest how to continue care at home or on a future trip.
What about downtime?
Downtime depends on the treatment. Fractional lasers and RF microneedling can cause redness, swelling and small scabs for several days. Subcision may cause bruising. Plan treatments early in your trip, avoid sun exposure and use gentle skincare while your skin heals.
How to plan your trip
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Scar and texture treatments are a common reason for these visits. Allow enough days in Seoul for the first healing phase before flying home.
