Atrophic Scar in Korea: How I Release Tethered Acne Scars With Subcision — A Gangnam Doctor's Honest Guide

If you have an atrophic scar that simply won't respond to laser no matter how many sessions you try, there's usually a reason — and it's not your skin being stubborn. Depressed acne scars are often held down by fibrous strands of tissue anchoring them to the layers below. Until those strands are released, the scar physically cannot rise, no matter how much you resurface the surface.

I'm Dr. Hyunji Kim, director at Delphic Clinic in Gangnam. I see a lot of international patients who've already spent money on laser abroad and felt let down. This guide explains what subcision really does for depressed acne scars, who it genuinely suits, and — honestly — who it doesn't.

What subcision actually is — in plain language

Subcision is a small procedure that uses a specialized needle placed at the junction between the dermis and the fat layer underneath. There, the needle releases the fibrous scar tissue that's pulling your skin downward. By severing those collagen fibrous bands, the depressed area is freed to elevate — and the controlled injury triggers new collagen to fill the space. That's why it works for various acne scars and deep, indented scars that surface treatments miss.

Here's what it isn't: subcision is not a resurfacing laser and it's not a filler. It doesn't smooth texture or shrink pores on its own, and it won't erase discoloration. It solves one specific problem — a scar that's tethered down — extremely well, and leaves the rest to other tools.

Who acne scar subcision is really for

In my chair, subcision earns its place for a very particular type of patient:

• People whose skin is being visibly pulled down by fibrous scar tissue — you can often see the tethering when you smile.
• Those with deep, rolling acne scars that never fully improved with laser.
• Patients with chickenpox scars or other deep indented scars.
• Anyone whose atrophic scars have plateaued after repeated resurfacing treatments.
• People who want to address the cause under the skin, not just polish the surface.

And who I steer elsewhere: if your scars are pure sharp "ice-pick" pits, subcision won't help much — those need a different approach. If your main concern is enlarged pores or overall texture, I'd usually point you toward RF microneedling like Potenza for pores and scars, or a resurfacing option such as Fraxel for texture and pigment. Often the best plan combines them.

How subcision compares — an honest comparison

No single tool fixes every scar. Here's roughly how subcision sits against the alternatives I use most for depressed acne scars.

The short version: subcision releases what's pulling a scar down; the others refine the surface. For many of my patients the winning strategy is subcision first, then resurfacing.

Before and after: what's realistic

Be patient with the timeline. Immediately after subcision the area is swollen and bruised, which can temporarily look worse. Real improvement is gradual — as new collagen forms over the following weeks, the released scar rises and settles. Deep atrophic scars usually soften noticeably rather than vanishing completely, and multiple sessions build the result. Individual healing varies a lot.

What to expect — step by step

1. 1

   1. Free consultation

   I examine your scars, stretch the skin to see which are tethered, and tell you honestly whether subcision — or something else — is the right call.

2. 2

   2. Numbing & prep

   We apply topical anesthetic and add local anesthetic at each lesion so the procedure stays comfortable.

3. 3

   3. The session

   Using a fine needle, I release the fibrous bands under each scar. Depending on how many lesions we treat, this takes about 30 to 60 minutes.

4. 4

   4. Recovery period

   Plan for around 5 days of recovery. Expect bruising and mild swelling; we give you clear aftercare so healing goes smoothly.

5. 5

   5. Results build over weeks

   As collagen fills the released space, the scar elevates over the following weeks. Deep scars may need a repeat session spaced apart.

How we do subcision at Delphic — and why it matters

Subcision is a doctor's procedure, not something to delegate. Knowing exactly which scars are tethered, at what depth to release, and how far to go without over-treating — that's judgment built over years. I perform every subcision myself, and I'd rather treat fewer lesions well than promise a miracle in one visit.

How much does subcision cost in Korea?

Subcision is priced by lesion and by the size of the area being released, so your total depends on how many scars we treat. Here are our genuine prices:

Coming from overseas? Here's how we make it easy

We have on-site English and Chinese interpreters, so nothing gets lost in translation during your consultation or aftercare instructions. We're a short walk from Sinnonhyeon Station Exit 3, the visit is one-day friendly, and — again — you pay exactly what a local pays. Just remember to allow for about 5 days of recovery when you plan your trip, in case bruising overlaps with photos or events.

Start with a free 1:1 consultation

The honest truth is that some scars are perfect for subcision and some aren't — and I can only tell by examining your skin in person. Come in for a free, no-pressure consultation and I'll tell you plainly whether it's worth it for you, or whether another approach would serve you better. If subcision isn't right, I'll say so.

Scars feel permanent until someone addresses the right layer — and for tethered atrophic scars, that layer is under the surface. If you've been let down by laser alone, subcision might be the missing piece. Come talk to me, and let's look at your skin together. — Dr. Hyunji Kim, Delphic Clinic, Gangnam, Seoul.
