A CO2 laser pass, 2 cc of Rejuran and a TA (triamcinolone) injection make up one scar laser session at ENTER Plastic Surgery, a scar laser treatment in Seoul, Korea for acne and surgical scars. Raised areas get the brief injection while the laser resurfaces the top layer, across 3 to 5 sessions spaced 4 to 6 weeks apart.
Is it for you?
Who scar laser treatment suits
Scars differ in shape, and the shape decides the tool. Atrophic acne scars sit below the surface as rolling dips, boxcar edges or narrow ice-pick pits. A thickened surgical line or a hypertrophic scar sits above it. One scar can have both: a raised ridge on one side and an uneven, pitted surface on the other. The scar laser set is built for that mix, because the steroid injection softens what stands up and the laser works on the surface in the same visit.
Change arrives step by step. The clinic describes the improvement as cumulative across a course, so the first session is a starting point. Keloids that keep growing beyond the original wound edge behave differently, and ear keloid removal is a separate procedure on the clinic's menu.
Usually a good fit
- Rolling, boxcar or ice-pick acne scars
- A healed surgical or injury scar with an uneven surface
- A scar with a raised edge and a rough surface together
- Time for 3–5 sessions spaced 4–6 weeks apart
- Able to reapply sunscreen every 3–4 hours while healing
We may suggest waiting
- Active acne breakouts or infection in the area
- An open wound or a scar that has not closed yet
- Pregnancy or breastfeeding
- Expecting the scar to vanish entirely
- A keloid still growing beyond the wound edge
How it works
How scar laser treatment works on raised and pitted scars
A CO2 laser is an ablative laser. Used in fractional mode, it makes a grid of microscopic channels in the skin and leaves untreated skin between them, and the healing response that follows remodels collagen in and around the scar. In a split-scar study of surgical scars, the half treated early with fractional CO2 looked better than the untreated half when assessed by blinded evaluators (Lee, 2013).
The two injections in the set have separate jobs. Triamcinolone, the TA in the set, is a corticosteroid that flattens firm, raised scar tissue; at the clinic, each injection point takes 1 to 2 seconds. Rejuran (PharmaResearch), a polynucleotide injectable, is added at 2 cc per session as part of the skin-recovery step after the laser.
The scar skin package takes a wider approach for spread-out acne scarring and texture. It combines laser toning, Clarity (Lutronic), Virtue RF (ShenB) microneedling and 3 cc of Juvelook (VAIM), a collagen-stimulating injectable, in one visit. A network meta-analysis of moderate to severe atrophic acne scars found combination therapy generally ahead of single treatments, with fractional CO2 plus subcision or PRP the most consistent, and it called for longer randomized trials (Ou, 2026). That review did not test this exact package.
Reading the scar
At consultationThe scar type, depth and color are mapped, along with which parts are raised and which are sunken, and the set or the skin package is chosen.
Numbing the area
A numbing cream is applied to the treatment area and left to take effect before anything else starts.
Injection and laser
20–40 minutesRaised parts receive the TA injection, 1 to 2 seconds per point, the surface is treated with the CO2 laser, and Rejuran is injected as part of the set.
Silicone dressing
From the next dayAfter cleansing and moisturizing on the day after treatment, a silicone dressing tape goes on and stays for about 7 to 10 days, until the skin has closed.

Prices
What a scar laser course costs in South Korea
There are two ways to book. The scar laser set bundles the CO2 laser, 2 cc of Rejuran and the TA injection into one visit, and it comes as a single session or as a 3- or 5-session course. The scar skin package combines four treatments for broader acne scarring and is offered as one visit or five.
The figures on these cards are before VAT, and 10% VAT is added when you pay. A course fits best when you can return every 4 to 6 weeks, so match the session count to how often you expect to be in Seoul.
Prices exclude VAT (10% VAT is added at payment).
Recovery
Aftercare following a scar laser session
Redness and a warm, tight feeling start straight after. Leave the silicone dressing off on this first day.
After cleansing and moisturizing, apply the silicone dressing tape. Replace it once or twice a day when it turns white and puffy with fluid. Flying home is possible from this day.
Scabs turn darker. Leave them alone; they come away on their own between days 7 and 10, and the dressing is removed once the skin has closed.
Laser redness fades over about four to five days in adults. A steroid ointment is not required; a plain moisturizer or gentle lotion is enough.
Avoid scrubs, peels and exfoliating products while the skin is sensitive, and reapply sunscreen every 3 to 4 hours.
The next session follows 4 to 6 weeks after the last, until the course of 3 to 5 sessions is complete.
Safety
Risks of scar laser treatment
Contact the clinic promptly if the treated skin becomes more painful, hot or swollen, oozes heavily, or blisters.
- Redness, swelling and scabbing in the first days.
- Darker patches in the treated skin (post-inflammatory hyperpigmentation), the main reason sun protection matters during healing.
- Infection, or a cold-sore flare in people prone to herpes simplex.
- Thinning, a dent or lighter color where the steroid was injected.
- Small lumps after the collagen-stimulating injectable in the skin package.
- Partial improvement, with some scars changing less than others.
The evidence has clear limits. A Cochrane review of laser therapy for hypertrophic and keloid scars judged the studies too varied, small and conflicting to support firm conclusions, and asked for long-term trials that report recurrence (Leszczynski, 2022). For surgical scars, a randomized split-scar trial found laser applied during the excision surgery itself no worse than laser at day 14 (Lin, 2023); it compared timings and says nothing certain about any single patient.

FAQ
Scar laser treatment FAQ for international visitors
How many scar laser sessions will I need?
The clinic plans 3 to 5 sessions, spaced 4 to 6 weeks apart. Deeper or more widespread scars sit toward the upper end of that range. Improvement builds from one session to the next, so the overall change is judged once the course is complete.
How long is the downtime after scar laser treatment?
Redness lasts about four to five days in adults. Scabs darken around day 3 and come away between days 7 and 10, while a silicone dressing tape covers the area from the day after treatment. Skip scrubs and peels for two weeks.
Can I fly home the day after a scar laser session?
Yes. The clinic's guidance is that flying is possible from the next day. Pack the silicone dressing tape and sunscreen, reapply the sunscreen every 3 to 4 hours, and change the tape once or twice a day when it turns white with fluid.
Does scar laser treatment hurt?
A numbing cream goes on before the session, and each TA injection point takes 1 to 2 seconds. Heat and stinging during the laser are expected and ease afterward, and the skin can feel warm and tight for the rest of the day.
Are scar laser prices quoted with or without VAT?
Without. One scar laser set is ₩300,000 + VAT, and the 3- and 5-session courses have their own listed prices. VAT of 10% is added at payment, so ask for the course you choose to be itemized in your quote.
How can I get a scar treatment plan before traveling to Korea?
Use the form on this page or WhatsApp, and we will get back to you as soon as possible. English-speaking staff are available at the clinic. Clear daylight photos of the scars, front and angled, together with your travel dates, make the first plan more specific.
Do I pay a deposit for a scar laser course?
Ask for the deposit and cancellation terms for your booking in writing before you pay. For a course, also ask how remaining sessions are handled if your travel plans change, since each visit is spaced 4 to 6 weeks from the last.
Does the scar laser treat acne scars and surgical scars alike?
Both are treated, with the balance adjusted to the scar. Pitted acne scars lean more on the laser and the skin package, raised surgical scars more on the TA injection. Studies support fractional CO2 for both at a low to moderate level of evidence (Ou, 2026).
Will my scar disappear completely?
No. The aim is a flatter, smoother scar that blends better with the skin around it. The clinic's guidance is that improvement adds up over the course and holds afterward, but how much a scar changes varies with its type, depth and skin, and some respond less.
What is the difference between the scar laser set and the scar skin package?
The set pairs a CO2 laser with 2 cc of Rejuran and a TA injection, suited to scars that are raised in places. The package combines laser toning, Clarity, Virtue RF microneedling and 3 cc of Juvelook for wider acne scarring and texture. Each is priced per visit.
Who carries out scar laser treatment?
Treatment takes place at ENTER Plastic Surgery, led by Dr. Jang Jin-woo, a Korean board-certified plastic surgeon. The clinic assigns your sessions when you book, and the same treatment plan, set by scar type, is followed across the course.
