About

What is acne scar treatment?

Acne scar treatment at Dear Clinic is not a single laser. Atrophic scars differ in depth, outline and how tightly fibrous tissue tethers them, so one device rarely settles a whole face evenly. So the work is layered. Our directors go deep, then middle, then surface, combining subcision, Potenza RF microneedling, CureJet and, where one lesion needs it, focused CO2 or Erbium laser work that is priced and delivered a single lesion at a time.

A depressed scar is a shortage of tissue underneath, which is why colour-correcting skincare does nothing to it. Where a breakout resolved, the repair left less collagen than the surrounding skin had, and strands of fibrous tissue often pull the floor of the scar downward from underneath. Light that only reaches the surface can polish the edges of that dent, but it cannot lift a floor that is being held down. That is the reasoning behind the sequence used here: free the tether first, then give the skin a reason to build volume back into the gap, then even out what remains on the surface.

The same logic applies in reverse to over-treatment. Firing a strong resurfacing setting across an entire face to chase a handful of deep pits asks healthy skin to recover from something it never needed. Mapping which scar sits where — and which ones are better left for a later session — is the part of this work that decides your outcome, and it happens at diagnosis, before any energy is switched on. Some faces leave that mapping with nothing booked: where the marks are flat and red instead of indented, we do not recommend the subcision route, and we say so before a course is quoted.

Scar Types

Which scars are on your face?

Depth, shape and the degree of fibrous tethering differ from scar to scar, and one setting cannot serve all of them.

TYPE 01

Boxcar

Box-shaped depressions with defined walls and a flat floor. Wide enough to catch shadow in overhead light, which is why they read worse in photographs than in a mirror.

TYPE 02

Ice-pick

Narrow and deep, shaped like a puncture. Their depth relative to their width is exactly what makes surface-only work under-deliver on them.

TYPE 03

Rolling & tethered

Soft, undulating dips with sloped edges, held down by fibrous strands underneath. These are the ones that respond to release before anything else.

TYPE 04

Marks & texture

Red or brown traces left after inflammation, plus the coarse surrounding texture. These sit flat in the skin and are handled differently from a true depression.

Most faces carry a mixture. Your plan is written around that mixture, and the same face can need a release step in one zone and nothing more than surface refinement in another. Male skin tends to be thicker, with heavier scarring across the cheeks and jaw, which changes the depth and energy chosen without changing the order of the steps.

The Layered Approach

The acne scar sequence, depth by depth

Three working depths, treated in order, because each step depends on what the one before it released.

DEEP LAYER

Subcision at the deep layer

A fine needle passes under a rolling or tethered scar and divides the fibrous strands anchoring its floor. Once the anchor is cut the depression can sit level with the skin around it, and the healing response that follows lays tissue into the space that opened. Bruising for roughly a week is the price of that release, and it is quoted to you before the needle is prepared.

MID LAYER

Potenza needles in the dermis

Needles first, energy second. Potenza carries radiofrequency down through the needle tips and releases it in the dermis, where scar walls and coarse texture sit, and depth and energy are set zone by zone, so a thin temple never receives the setting written for a thick cheek.

SURFACE LAYER

CureJet and per-lesion laser work

CureJet is a needle-free jet injector that works into the tissue around a scar without passing a needle through it. Single stubborn lesions are handled on their own, at ₩10,000 (≈ $5) each.

Where D-ARC Solution fits

Dear Clinic runs this layered thinking as a named signature programme, D-ARC Solution — Decreasing Acnes Solution — which addresses active acne and the scarring it leaves inside one structured protocol instead of as unrelated visits. Its components are the ones described on this page plus a pigment laser step for post-inflammatory marks, a fractional laser step for texture at spaced intervals, and Juvelook where thinned tissue around a scar needs supporting. The programme has its own guide, D-ARC Solution, with the core price; your director will tell you at consultation whether the programme or a shorter individual plan suits your face.

The limits of scar work

Erasure is not on offer. Published research on atrophic acne scars reports degrees of improvement; disappearance is not among the outcomes any of it describes. Deep ice-pick scars respond partially and slowly, and a face that begins with severe scarring will still read as improved when the sequence ends. No one can tell you in advance how far your own scars will travel. What a plan can give you is an estimate of how much change is available to your skin, together with the review points at which the two of us check whether that estimate is holding up.

How a scar plan is built at Dear

01 — THE FULL ARSENAL

Every step of the sequence is in-house

Subcision, RF microneedling, jet injection, resurfacing lasers, pigment lasers and boosters are all on site. A plan can therefore use one of the four steps priced on this page or all four, and a single subcision session at ₩500,000 (≈ $355) with nothing else booked is a complete plan when that is what the map shows. Which steps your face needs is a diagnostic finding, written down before any of them is quoted.

02 — DIAGNOSIS FIRST

Five light sources over a scar map

The map comes first. Scar type, distribution and skin thickness are read from your EVE Muse 3D scan and its five-light-source AI analysis before a single setting is chosen, and that reading is what decides which zones need a release step, which need dermal rebuilding and which need nothing at all this session.

03 — DIRECTOR-PERFORMED

Director-performed, scar by scar

Subcision and per-lesion laser work reward a steady, experienced hand more than almost anything else in aesthetic medicine. Your treatment is performed by our directors, who adjust as they go instead of running one fixed pass over the whole face.

What a wrong scar reading costs you

With a lifting treatment, a slightly generous plan mostly costs money. With scars, an over-aggressive plan costs recovery time and can leave the skin more reactive than it started, with lingering redness or a patch of altered pigment where the energy was heaviest. So depth and fibrosis are read before anything is switched on, and the sequence is reviewed between sessions instead of being sold as a fixed course of ten on the first visit. If your scarring is mild enough that two carefully placed sessions will do the work, that is what you are told at diagnosis.

Published rates as of September 2026. Scar work is normally a sequence spread across several visits, so your director estimates at diagnosis how many sessions your pattern is likely to need and what a realistic result looks like, instead of pre-selling a package on day one. The D-ARC Solution programme is quoted from its component steps until a programme rate is confirmed. Each of the four steps above is listed on the full price list, and a subcision slot can be booked on Sundays and public holidays like any other day.

Caution

Aftercare for subcision and microneedling

Bruising is normal after subcision and can last around a week; book the session with a clear week in front of you.
Redness, warmth and small pinpoint marks after microneedling usually settle over two to three days.
Daily sunscreen is not optional while the skin is repairing — sun on healing skin is the most common cause of lingering discolouration.
Pause saunas, pools, heavy workouts, makeup and strong actives for the period your director specifies.
Tell us if anything stays irritated, swollen or tender beyond the expected window — aftercare follow-up is part of the treatment.

FAQ

Acne scar treatment, answered

Is acne scar treatment worth it?
If depressions are what bother you in photographs and daylight, then yes, in the sense that atrophic scarring is one of the few skin concerns that will not improve on its own with time or skincare. What it is worth depends on how much change is realistically available to your scar pattern, and that number is given to you at diagnosis rather than implied by a brochure. Improvement here is measured in degrees, never in erasure.
How much does acne scar treatment cost in Seoul?
At Dear Clinic, subcision is ₩500,000 (≈ $355), a standard Potenza session is ₩250,000 (≈ $180), full-face CureJet is ₩500,000 (≈ $355) and focused CO2 or Erbium work is ₩10,000 (≈ $5) per lesion. Your plan may use one of these or several in sequence; the combination and the total are confirmed with you before the first session begins.
What is subcision, and why is it done first?
Subcision passes a fine needle beneath a rolling or tethered scar to divide the fibrous strands that hold its floor down. It is done first because the strands are the reason the dent exists at that depth: until they are released, energy delivered above them is working against an anchor. Once released, the healing response fills part of the space that opens up.
Which scar types respond best?
Rolling and tethered scars generally respond most visibly, because releasing the anchor produces a structural change rather than only a textural one. Boxcar scars improve with a combination of release and dermal rebuilding. Ice-pick scars, narrow and deep by definition, are the slowest and most partial responders, which is why they are often addressed lesion by lesion instead of with a full-face pass.
How many sessions will I need?
There is no fixed number, and any figure quoted before your skin has been examined is guesswork. Scar sequences are normally spaced several weeks apart so tissue can rebuild between visits, and how many you need depends on scar depth, distribution and how your skin repairs. Your director estimates a range at diagnosis and reviews it as you go instead of selling a fixed course upfront.
Does it hurt?
Topical numbing is applied first and given time to take effect, and for subcision a local anaesthetic is used as well. Most people describe pressure and heat during microneedling, with sharper moments over bony areas such as the jawline. Tell your director when a zone is uncomfortable; settings and pacing are adjusted while the session runs.
How much downtime should I plan for?
It depends on which steps your plan uses. Subcision commonly leaves bruising for about a week. RF microneedling leaves a red, warm face on the day, easing over two or three days, sometimes with a faint grid of tiny marks. Per-lesion laser work leaves small crusts on the treated spots. Your director tells you which of these applies before you book.
When will I see a change, and does it last?
Texture often looks calmer once the initial redness settles, but the meaningful change comes from collagen rebuilding over the weeks and months after each session, and it accumulates across the sequence. Structural improvement from a released scar does not simply undo itself, though ageing and new breakouts continue to affect your skin, so maintenance and acne control remain part of the picture.
RF microneedling or a resurfacing laser — which one?
They reach the skin differently. A fractional CO2 or Erbium laser works through the surface with light and typically involves more visible recovery; RF microneedling delivers energy from needle tips under the surface, leaving more of the outer layer intact. Both are documented for acne scars. Because Dear Clinic carries both, the choice follows your scar map and the recovery time you actually have.
What is the D-ARC Solution?
D-ARC Solution, short for Decreasing Acnes Solution, is Dear Clinic's signature programme for acne and acne scarring. It sequences the steps described on this page inside one protocol, layer by layer, so a breakout and its aftermath are not managed as separate visits. Its dedicated page, D-ARC Solution, is live on this site with the core programme price; at consultation your director confirms whether the programme or its individual steps suit you.
Can I be treated while I still have active acne?
Usually not in the same way. Inflamed, actively breaking-out skin is treated to calm it first, because scar work on moving inflammation risks aggravating the skin and wastes sessions on a target that is still changing. In some cases a gentle step can run alongside acne management; that decision belongs to your director after examining your skin.
I am in Seoul for one week — can subcision fit inside that?
The treatment fits easily; the bruise is the part that needs planning. Diagnosis, consultation and a first session can run on the same day when your skin is calm, so book the subcision early in the trip and keep it clear of a wedding, a shoot or a flight home in the days that follow. Shaving is paused while the skin recovers, which matters for jawline scarring in particular. Everyone pays the same published rate, the clinic opens on Sundays and public holidays too, and the form below is answered in English within one business day with no deposit taken to hold the slot.

Scientific Evidence

Science behind the scar protocol — peer-reviewed references

The dermal rebuilding step in this protocol is the most heavily documented part of it. Fractional radiofrequency delivered through microneedles has been examined for atrophic acne scars in randomised split-face designs, against fractional CO2 lasers, against micro-plasma radiofrequency, and pooled in meta-analysis; separate work looks at pore size as an outcome. Several of these studies were carried out in Asian patients, which matters when planning depth and energy for the skin types we treat every day in Cheongdam.

All references below carry verifiable DOIs from indexed journals. They report degrees of improvement across treatment courses, not clearance, and they inform how we pace a sequence; they do not predict what any one face will achieve.
