Old Acne Scars in Myeongdong: Best Treatment Options
Old Acne Scars in Myeongdong: Best Treatment Options
Introduction
Old acne scars can remain visible for years after active acne has disappeared. Some become less noticeable over time, but established scars caused by changes in collagen and deeper skin structure usually do not disappear completely on their own. This is especially true for depressed or atrophic acne scars.
For patients researching old acne scar treatment in Myeongdong, the most important step is identifying what type of scar you have. Old scars may include rolling scars, boxcar scars, ice pick scars, or a combination of several types. Each responds differently to treatment. Medical reviews consistently emphasize that acne scar treatment should be matched to scar morphology and that combining procedures may produce better results than relying on one technique alone.
Treatment options available in South Korea can include fractional laser resurfacing, RF microneedling, microneedling, subcision, punch techniques, TCA CROSS, and dermal fillers. The appropriate choice depends on scar depth, skin type, previous treatments, pigmentation tendency, and individual treatment goals.
Myeongdong is a convenient location in central Seoul for patients seeking dermatology care. However, the best treatment is not necessarily the newest or most heavily marketed procedure. A detailed assessment should come before treatment selection.
What Are Old Acne Scars?
An old acne scar is a persistent change in the skin that remains after an acne lesion has healed.
Old scars can be:
- Rolling scars: broad, shallow depressions with soft edges
- Boxcar scars: wider depressions with relatively defined edges
- Ice pick scars: narrow, deep pits
- Mixed scars: combinations of two or more types
Atrophic acne scars develop when inflammation damages collagen and supporting tissue during the healing process. Once established, these structural changes are different from temporary acne marks or discoloration.
This distinction is important because pigmentation may respond to topical skincare or pigment-focused treatments, while a deep depression generally requires a procedure that addresses the underlying structure.
Old Acne Scars vs. Acne Marks
Not every dark or red area left after acne is a true scar.
Post-inflammatory hyperpigmentation is a change in skin color rather than a depression. It may gradually fade and can often be managed with appropriate skincare and pigment-directed treatments.
Atrophic acne scars, on the other hand, involve a change in skin contour. They may remain visible even when pigmentation has completely resolved.
You can have both at the same time.
A dermatologist may therefore recommend treating pigmentation separately from structural scarring. Improving both can create a more noticeable overall improvement in skin appearance.
Why Do Old Acne Scars Remain?
During severe acne inflammation, collagen and other components of the dermis can be damaged. When the skin repairs itself, the replacement tissue may not have the same organization or volume as normal skin.
Some scars also develop fibrous attachments underneath the surface. These bands can pull the skin downward, producing the characteristic appearance of rolling scars.
Established scars can therefore involve:
- Collagen loss
- Abnormal collagen remodeling
- Loss of dermal volume
- Fibrous tethering
- Irregular scar edges
- Changes in skin texture
Because of these structural changes, ordinary moisturizers or exfoliating products generally cannot completely flatten a mature depressed scar.
Does the Age of an Acne Scar Matter?
The age of a scar is relevant, but it does not automatically determine whether treatment can help.
A scar that has been present for several years may still respond to procedures designed to remodel collagen or correct its structure.
However, older scars can be well established, and significant improvement may require several treatments.
The more important factors are usually:
- Scar type
- Scar depth
- Scar size
- Skin type
- Degree of tethering
- Previous procedures
- Individual healing response
In other words, "old" does not mean "untreatable."
Who Is a Good Candidate for Old Acne Scar Treatment?
You may be a candidate for professional treatment if you have stable acne and persistent depressed scars that affect your appearance or confidence.
A dermatologist may consider treatment when you have:
- Longstanding rolling scars
- Established boxcar scars
- Deep ice pick scars
- Mixed acne scars
- Uneven facial texture
- Residual depressions after previous acne treatment
Active inflammatory acne should generally be controlled before extensive scar revision. Otherwise, new lesions may continue creating additional scars.
During consultation, disclose previous laser treatments, chemical peels, microneedling, fillers, medications, allergies, abnormal scarring, and any history of post-inflammatory hyperpigmentation.
Fractional Laser for Old Acne Scars
Fractional laser resurfacing is one of the established options for atrophic acne scars.
The treatment creates microscopic zones of controlled injury in the skin, stimulating wound healing and collagen remodeling.
Potential benefits include:
- Improved skin texture
- Softer scar edges
- Collagen remodeling
- Reduced visibility of some depressed scars
- Treatment of broader areas of uneven texture
Fractional laser may be particularly useful when old scars cover a relatively large area rather than appearing as only a few isolated depressions.
However, deep scars may not respond sufficiently to laser alone. Reviews note that deep ice pick scars, for example, often require more targeted approaches.
Fractional CO₂ Laser
Fractional CO₂ laser is an ablative resurfacing procedure that produces controlled microscopic columns of thermal injury.
It can provide substantial collagen remodeling and may improve the appearance of established acne scars.
However, it can also involve more visible recovery than some non-ablative or needling-based treatments.
Possible temporary effects include:
- Redness
- Swelling
- Peeling
- Crusting
- Sensitivity
- Temporary pigmentation changes
A recent systematic review found that fractional CO₂ laser and needling-based treatments can provide comparable overall improvement for atrophic acne scars, while CO₂ laser had a higher risk of post-inflammatory hyperpigmentation than standard microneedling in the analyzed studies.
This makes individual skin type and pigmentation history particularly important when selecting treatment.
RF Microneedling for Old Acne Scars
Radiofrequency microneedling combines controlled needle penetration with RF energy delivered into the skin.
The objective is to stimulate collagen remodeling while creating controlled thermal effects beneath the surface.
RF microneedling may be considered for:
- Shallow to moderate atrophic scars
- Boxcar scars
- Some rolling scars
- Generalized uneven texture
- Patients seeking collagen remodeling with relatively controlled downtime
It can be especially useful when old acne scars are accompanied by broader texture concerns.
However, RF microneedling cannot automatically correct every deep scar. Very narrow ice pick scars or sharply defined deep depressions may require more targeted procedures.
Microneedling for Established Scars
Microneedling creates controlled microscopic injuries that trigger the skin's wound-healing response.
It can improve:
- Mild atrophic scarring
- Surface texture
- Collagen remodeling
- Overall skin smoothness
Microneedling is generally more suitable for shallow or moderate textural problems than very deep individual scars.
It may also be used as part of a longer treatment plan, particularly when the patient prefers a procedure with relatively limited downtime.
The expected improvement should remain realistic. Microneedling can soften the appearance of old scars, but it does not physically remove a deep scar or release strong fibrous tethering.
Subcision for Old Rolling Scars
Subcision is particularly relevant when old acne scars are tethered beneath the skin.
During the procedure, a needle or specialized instrument is inserted under the scar to release fibrous bands pulling the skin downward.
This makes subcision especially relevant to rolling scars.
The procedure can also be combined with resurfacing or other collagen-remodeling treatments. Reviews have found that combination approaches can be useful because subcision addresses deeper tethering while resurfacing improves the skin surface.
Possible temporary effects include:
- Bruising
- Swelling
- Tenderness
- Bleeding
- Temporary discoloration
Because bruising can be visible, international patients should allow sufficient recovery time before important events.
Punch Techniques for Deep Old Scars
Punch techniques can be useful when an old scar is particularly deep and well defined.
Depending on the scar, a dermatologist may consider:
- Punch excision: removes the scar tissue
- Punch elevation: raises the depressed scar toward surrounding skin
- Punch grafting: replaces removed scar tissue with a skin graft
Punch elevation is particularly associated with selected boxcar scars, while punch excision may be considered for certain deep ice pick scars.
These techniques are targeted rather than full-face procedures, making them useful when a small number of scars are significantly deeper than the surrounding skin.
TCA CROSS for Old Ice Pick Scars
TCA CROSS is a targeted chemical reconstruction technique commonly used for narrow, deep acne scars.
A concentrated trichloroacetic acid solution is applied directly into selected scars to stimulate controlled tissue remodeling.
It is particularly associated with ice pick scars and narrow boxcar scars rather than broad rolling scars.
If you have mixed old acne scars, a dermatologist may use TCA CROSS for ice pick scars while selecting laser, RF microneedling, or subcision for other areas.
Because the technique uses a high-strength chemical solution, it should be performed by an appropriately trained medical professional.
Dermal Fillers for Depressed Old Scars
Dermal fillers can improve selected depressed acne scars by adding volume beneath the depression.
Hyaluronic acid fillers are one option that may be considered for appropriate scars.
Fillers can be useful when:
- The depression is suitable for volumization
- There is localized volume loss
- A residual depression remains after another procedure
- The patient wants a contour-focused treatment
Fillers do not remove scar tissue.
Possible complications include swelling, bruising, asymmetry, lumps, and rare but serious vascular complications. The treatment therefore requires careful anatomical assessment and appropriate injection technique.
Combination Treatment for Old Acne Scars
Old acne scars often involve more than one structural problem.
For example, a patient may have:
- Rolling scars requiring subcision
- Boxcar scars requiring resurfacing or punch elevation
- Ice pick scars requiring TCA CROSS or punch treatment
- General texture irregularity requiring RF microneedling or fractional laser
A customized combination plan may therefore produce a more comprehensive result than treating every scar with the same procedure.
Possible combinations include:
- Subcision followed by fractional laser.
- Punch elevation followed by resurfacing.
- RF microneedling with targeted treatment for deeper scars.
- TCA CROSS for ice pick scars combined with broader resurfacing.
- Subcision with carefully selected filler treatment.
Combination treatment does not necessarily mean performing all procedures on the same day. Staging treatments can allow the skin to recover and the clinician to evaluate the response before the next step.
What Results Can You Expect?
The goal of old acne scar treatment is usually improvement rather than complete removal.
Potential improvements include:
- Reduced scar depth
- Softer edges
- Smoother skin texture
- Less noticeable shadows
- More even skin contour
- Improved overall appearance
Results vary substantially between patients.
Rolling and boxcar scars may respond more readily to certain procedures than deep ice pick scars. The combination of scar type, depth, treatment selection, and individual healing has a major effect on the final result.
It is also important to distinguish temporary swelling from the actual treatment result. Early after a procedure, inflammation can make scars temporarily appear smoother or more prominent.
How Many Treatments Are Needed?
There is no universal number of sessions for old acne scars.
Some patients may see meaningful improvement after one targeted procedure, while others require a series of treatments.
The number depends on:
- Scar severity
- Number of scars
- Treatment modality
- Skin type
- Recovery time
- Previous procedures
- Treatment goals
Collagen-remodeling procedures often require multiple sessions because improvement develops gradually.
Deep or mixed scars may also require different procedures performed at different stages.
A dermatologist should reassess the skin during treatment rather than automatically repeating the same procedure.
How Long Do Results Take?
The timeline depends on the treatment.
Laser and microneedling-based procedures rely substantially on collagen remodeling, so improvement can continue for weeks or months.
Subcision produces an immediate structural release in appropriate tethered scars, but the final appearance also depends on healing and collagen formation.
Punch procedures involve localized wound healing and may initially cause redness or swelling.
Fillers can create an immediate contour change, although early swelling can temporarily alter the appearance.
Patients should therefore avoid judging final results immediately after treatment.
Are Old Acne Scars Permanent?
Established acne scars are considered long-term structural changes, but that does not mean they cannot be improved.
Professional treatments can remodel scar tissue, stimulate collagen, release tethering, or restore localized volume.
However, no responsible clinician should promise completely scar-free skin.
The realistic objective is to reduce visibility rather than guarantee total elimination.
This distinction is particularly important for patients considering expensive treatment plans in another country.
Old Acne Scars and Asian Skin
Patients with Asian skin may be particularly concerned about post-inflammatory hyperpigmentation following procedures that intentionally create controlled inflammation.
Many acne scar treatments can be performed on Asian skin, but treatment parameters should be individualized.
Important considerations include:
- Fitzpatrick skin type
- History of pigmentation after procedures
- Current pigmentation
- Recent sun exposure
- Previous laser reactions
- Treatment intensity
- Recovery and sun protection
Recent evidence comparing fractional CO₂ laser with needling-based treatments highlights the importance of considering pigmentation risk when selecting a resurfacing procedure.
A consultation should therefore address both scar improvement and the possibility of pigmentary complications.
How Much Does Old Acne Scar Treatment Cost in Myeongdong?
There is no single price for old acne scar treatment in Myeongdong.
Cost can vary according to:
- Scar type
- Treatment area
- Number of scars
- Procedure selected
- Number of sessions
- Laser technology
- RF microneedling
- Subcision

Why Consider Myeongdong for Old Acne Scar Treatment?
Myeongdong is centrally located in Seoul and is convenient for patients staying in the city.
For international visitors, its accessibility can make it practical to combine a dermatology appointment with accommodation, transportation, and other Seoul activities.
However, location should not be the main reason for selecting a clinic.
Look for:
- Qualified medical professionals
- Experience with acne scar revision
- Experience treating your skin type
- Accurate scar classification
- Appropriate treatment technology
- Clear pricing
- Realistic discussion of expected results
- International patient communication
- Appropriate aftercare
The clinic's ability to create a treatment plan based on your actual scar morphology is more important than the number of procedures advertised.
Tips for International Patients Visiting Korea
If you are traveling to South Korea for old acne scar treatment, plan around recovery.
Before booking:
- Ask whether an in-person consultation is required.
- Confirm the expected downtime.
- Ask whether one appointment is enough.
- Determine whether multiple sessions are likely.
- Ask when you can safely return to normal activities.
- Avoid treatment immediately before major events.
- Confirm how follow-up will be handled.
- Ask what to do if you experience an unexpected reaction.
If your stay in Seoul is short, procedures requiring several sessions may need to be planned across multiple trips.
How to Prepare for Treatment
Preparation varies according to the selected procedure.
Your dermatologist may recommend:
- Avoiding tanning
- Using gentle skincare
- Avoiding unnecessary exfoliation
- Reporting active acne or skin infections
- Disclosing medications and allergies
- Temporarily stopping certain irritating products if instructed
- Following specific pre-treatment instructions
Do not aggressively exfoliate or introduce unfamiliar skincare products shortly before treatment.
If you have previously developed dark marks after laser, chemical peels, or other procedures, tell your dermatologist before treatment.
Aftercare and Recovery Tips
Aftercare depends on the procedure performed.
General principles include:
- Keep the treated area clean.
- Follow wound-care instructions.
- Avoid picking or scratching.
- Use recommended barrier-support products.
- Protect treated skin from ultraviolet exposure.
- Avoid unnecessary heat and irritation during early healing.
- Follow instructions about makeup and exercise.
- Attend recommended follow-up appointments.
After invasive procedures such as subcision or punch treatment, visible bruising or swelling may temporarily affect your appearance.
Seek medical advice promptly if you develop increasing pain, spreading redness, significant swelling, pus, fever, or other concerning symptoms.
Frequently Asked Questions
Can old acne scars still be treated?
Yes. Established acne scars can often be improved with procedures such as fractional laser, RF microneedling, subcision, punch techniques, TCA CROSS, or fillers. The appropriate treatment depends on the scar type and depth.
What is the best treatment for old acne scars in Myeongdong?
There is no universal best treatment. Rolling scars may benefit from subcision, boxcar scars may respond to resurfacing or punch elevation, and ice pick scars may require TCA CROSS or punch techniques.
Can laser remove old acne scars?
Fractional laser can reduce the appearance of many atrophic acne scars by stimulating collagen remodeling. Deep scars may require additional targeted treatment because laser alone may not correct the entire structural defect.
Are old acne scars permanent?
Established acne scars are long-term structural changes, but they can often be improved. Complete removal cannot be guaranteed.
How many treatments are needed for old acne scars?
The number varies according to scar type, depth, skin type, procedure, and individual response. Some patients need one targeted procedure, while others require several sessions or combination treatment.
Is subcision suitable for old acne scars?
Subcision is particularly useful for old rolling scars that are tethered to deeper tissue. It is generally less suitable as the only treatment for every boxcar or ice pick scar.
Is RF microneedling good for old acne scars?
RF microneedling can improve collagen remodeling and skin texture and may be useful for selected atrophic scars. It may be incorporated into a combination treatment plan when deeper scars require additional targeted procedures.
Can old acne scars be completely removed after several treatments?
Even after multiple treatments, complete removal cannot be guaranteed. The realistic goal is to reduce scar depth and visibility and create a smoother overall appearance.
Is acne scar treatment safe for Asian skin?
Many treatments can be used safely when properly selected and adjusted. Pigmentation risk should be assessed individually, particularly before aggressive laser resurfacing.
Conclusion
Old acne scars in Myeongdong can often be improved, even when they have been present for many years. The key is understanding that old scars are not all the same.
Rolling scars may benefit from subcision, while boxcar scars can be candidates for fractional resurfacing, RF microneedling, or selected punch techniques. Deep ice pick scars may require more targeted approaches such as TCA CROSS or punch treatment. Combination therapy can be useful when several scar types exist on the same face.
For international patients visiting South Korea, Myeongdong offers a convenient Seoul location, but clinic selection should be based on medical expertise, appropriate scar assessment, realistic expectations, and aftercare rather than convenience alone.
Before treatment, ask about your exact scar types, recommended procedures, expected improvement, recovery time, pigmentation risks, number of sessions, and total cost.
Old acne scars may not disappear completely, but a carefully planned treatment strategy can make them significantly less noticeable and improve the overall smoothness and texture of the skin.
