Korean Acne Scar Treatment: Why I Plan It Scar by Scar, Not Machine by Machine

I'm Dr. Hyunji Kim, director of Delphic Clinic in Gangnam, a minute's walk from Sinnonhyeon Station. I trained through Korea University Medical Center and I'm a member of the Korean Academy of Aesthetic Surgery & Laser Medicine and the Korean Society for Laser Dermatology & Hair. Laser, lifting and anti-ageing care fill my days, and acne scars are some of the most satisfying and most misunderstood cases I see, which is why a proper Korean acne scar treatment plan starts with looking, not with a machine.
Several times a week an overseas patient sits down and asks some version of the same thing: which Korean acne scar treatment should I book? Usually they have a screenshot of one device and a strong opinion about it. My answer is almost always the same: your scars are not one problem, so they rarely have one solution. This page explains how I read scars and build a plan around them.
Read your own scars first: a five-minute mirror check
Before any consultation, stand beside a window with light coming from one side and look at your cheeks in a hand mirror. Side light shows depth that ring lights flatten. Then gently stretch the skin between two fingers and watch what happens to each scar.
- Soft, wide dips that flatten a little when you stretch the skin: likely rolling scars
- Dips with sharper, box-like edges that stay visible when stretched: likely boxcar scars
- Small, deep, narrow pits like an enlarged pore: likely ice pick scars
- Flat red or brown marks with no dip at all: not true scars, but post-acne marks
- New spots still appearing every week: the acne needs attention before the scars
Write down which of these you see and roughly where. It makes a consultation faster and helps you understand why I might suggest three different tools for one cheek. If most of what you see is red rather than dented, my guide to calming red acne marks with GV laser is the more relevant read.
Which tool fits which scar in a Korean clinic
Subcision is the one most patients have never heard of, and for rolling scars it is often the missing piece. A fine needle works under the scar to cut the bands pulling it down, so the skin can lift and fill. I describe the procedure and its recovery in detail in my scar subcision guide.
Potenza delivers radiofrequency energy through microneedles into the dermis, which prompts collagen remodelling under shallow scars and enlarged pores. Fraxel works more at the surface to even out texture. If you are trying to understand the difference between the two lasers, I compared them in PicoSure vs Fraxel.
Why one device on repeat usually disappoints
The most common story I hear is five sessions of the same laser with little change. That is rarely the laser's fault. A tethered rolling scar will not rise no matter how much collagen you build around it, because the band underneath keeps pulling it down.
So I often release the tethered scars first, let them settle, and then remodel the surrounding texture. The order matters as much as the tools. Doing it the other way round tends to spend money on the easier part of the problem.
I treat the scar in front of me, not the device on the menu. If a scar needs a needle rather than a laser, I will say so.— Dr. Hyunji Kim, Delphic Clinic
Is Korea a good place for acne scar treatment?
Korea has a mature scar-care culture and a wide range of genuine devices under one roof, which makes combination plans practical in a single clinic. The honest catch is time: scar courses need repeat sessions, and a single trip only starts the process.
It suits you best if you visit Seoul more than once a year, or can stay a few weeks. It suits you less if you want one visit to finish the job. Pricing for a full-face subcision plan depends on how many scars and how large, so here are our real per-lesion prices.
| [Scar] Subcision - 1 lesion (500 KRW coin size) | ₩100,000$70 |
| [Scar] Subcision - 1 lesion (Business card size) | ₩300,000$220 |
When I would tell you to wait, or not to start
- Active, inflamed acne is still forming new spots each week
- You are taking or have recently finished oral isotretinoin; timing needs discussing first
- You tend to form raised or thickened scars after injury
- You need a finished result before a fixed event in a few weeks
- The marks are flat colour rather than dents, where a scar course would be the wrong tool
None of these is a final no. They are reasons to change the order or the tool, and I would rather tell you that in consultation than take a booking that will not help you.
Questions to paste into your consultation message
- Which scar types do you see on my face, and where?
- Which scars need subcision, and which need a laser or RF microneedling?
- In what order would you do them, and why?
- How many sessions would you expect, and how far apart?
- Who performs subcision: the doctor, or someone else?
- Is the price the same for international patients?
If you want to see how texture changes in the weeks after RF microneedling, my Potenza before and after timeline walks through day three to month three.
A realistic scar plan across two Seoul trips
- 1
Trip one, day one
Consultation and scar mapping. If you are a candidate, subcision can be done the same day, so the bruising settles while you are still in Seoul.
- 2
Trip one, later that week
Mild swelling and bruising usually ease within about five days. Avoid heavy exercise and saunas while it settles.
- 3
Between trips
Keep acne under control and protect your skin from the sun. The released scars continue to settle over the following weeks.
- 4
Trip two
We reassess and move to texture work with Potenza or Fraxel, which usually allows a same-day return to normal life.

Before the procedure, Dr. K carefully examined my skin condition and explained everything in a kind and easy-to-understand way, which made me feel very comfortable and reassured. During the treatment, I could really tell that Dr. K was highly skilled, so I felt confident and at ease throughout the entire process. Overall, I was very satisfied with my experience. It’s definitely a clinic I would love to visit again.
I had a really great experience at Delphic Clinic. The staff were very friendly and made me feel comfortable from the moment I walked in. They explained everything clearly in English and didn’t try to oversell unnecessary treatments, which I really appreciated. The clinic is very clean and modern, and the whole process felt professional and well-organized. Overall, I would definitely recommend this clinic, especially if you’re a foreigner looking for a trustworthy place in Korea.

Frequently asked questions
What is the most effective Korean acne scar treatment?
There is no single one. Tethered rolling scars respond to subcision, shallow boxcar scars and texture respond to RF microneedling such as Potenza, and surface irregularity responds to fractional laser such as Fraxel. Most faces have a mix, so a combined plan usually does more than any one machine.
How many sessions does acne scar treatment in Korea take?
It depends on scar depth and type. Most people need a course of several sessions spaced weeks apart rather than one visit, which is why I plan around how often you can return to Seoul.
Can acne scars be completely removed?
Honestly, the realistic goal is improvement: shallower scars, smoother light reflection and less visible texture. I would be wary of any clinic that promises a scar-free face.
Can I treat acne scars while I still have active acne?
Active inflammation usually comes first. Treating scars while new breakouts keep forming means new scars keep appearing, so I calm the acne before committing to a scar course.
What downtime should I expect from acne scar treatment in Korea?
It varies by tool. Potenza and Pico Fraxel usually allow a same-day return to normal life, while subcision can leave bruising and swelling for around five days, so I schedule it early in a trip.
