Quick Answer:
Acne scars treatment depends on what is actually left behind after acne heals. Depressed ice-pick, boxcar, and rolling scars are structural scars and usually need procedures that remodel or release scar tissue. Raised hypertrophic or keloid scars need a different approach, while flat brown or red post-acne marks are not true scars and are usually treated as pigmentation or vascular changes. The safest plan starts by controlling active acne, identifying the scar type, choosing treatment according to skin tone and pigment risk, and setting realistic expectations because improvement is usually gradual rather than complete scar removal.
What Is Acne Scars Treatment?
Acne scars treatment is a broad term for dermatological and cosmetic treatments used to improve textural scarring, raised scars, and post-acne discolouration. The correct treatment depends on whether the concern is a true structural scar or a flat colour change left after inflammation.
True acne scars involve a change in skin structure. Atrophic scars sit below the surrounding skin because tissue has been lost, while hypertrophic and keloid scars are raised because excess scar tissue has formed. Flat brown, grey, red, or pink marks after acne are usually post-inflammatory hyperpigmentation (PIH) or post-inflammatory erythema (PIE), not structural scars.
| Post-Acne Concern | Typical Appearance | Main Treatment Goal |
|---|---|---|
| Ice-pick scars | Narrow, deep depressions | Target the depth and sharply defined scar walls |
| Boxcar scars | Round or oval depressions with more defined edges | Improve depth and surface transition |
| Rolling scars | Broad, shallow depressions with a wave-like appearance | Release tethering and remodel collagen |
| Hypertrophic scars | Raised scar tissue that stays within the original acne area | Flatten and soften excess scar tissue |
| Keloid scars | Raised scar tissue extending beyond the original lesion | Control scar growth and symptoms under specialist care |
| PIH | Flat brown, grey, or darker marks | Reduce excess pigment and prevent further darkening |
| PIE | Flat red or pink marks | Allow vascular/inflammatory redness to settle or use selected vascular treatments |
A consistent skin care routine can support acne control, barrier health, and pigmentation management, but structural scars usually need more than topical skincare alone.
Types of Acne Scars Treatment: Which Is Right for You?
Different scar patterns respond to different treatments, and many people have more than one scar type. Treatment should therefore be based on scar morphology rather than choosing one procedure for the entire face.
Atrophic Scars: Ice Pick, Boxcar and Rolling
Atrophic scars are depressed because the skin has lost structural support. Depending on the scar type, treatment may involve microneedling, radiofrequency microneedling, fractional laser resurfacing, subcision, focal chemical reconstruction techniques, or selected fillers.
- Microneedling: Can improve selected rolling and boxcar scars by stimulating collagen remodelling. It is less useful as a stand-alone treatment for very deep ice-pick scars.
- RF microneedling: Combines controlled needling with radiofrequency energy and may be useful for selected atrophic scars.
- Fractional laser resurfacing: Can improve textural scarring but requires careful selection in darker or pigment-prone skin because post-inflammatory hyperpigmentation can occur.
- Subcision: A clinician-performed procedure used mainly for tethered rolling scars by releasing fibrous bands beneath the skin.
- Focal chemical reconstruction: Techniques such as TCA CROSS may be used by experienced clinicians for selected narrow, deep scars.
- Dermal fillers: Can temporarily elevate selected depressed scars, but filler choice and injection safety require an appropriately qualified medical injector.

Hypertrophic and Keloid Scars
Raised scars require a different strategy from depressed acne scars. Depending on the scar, a dermatologist may consider silicone therapy, intralesional corticosteroid treatment, other injectable scar treatments, vascular laser, cryotherapy, or combination management. Keloids have a meaningful recurrence risk and should be treated by a clinician experienced in scar management.
Post-Inflammatory Hyperpigmentation and Red Marks
PIH and PIE are not true scars because the skin surface may remain flat. PIH may respond to topical retinoids, azelaic acid, niacinamide, selected brightening agents, and carefully chosen chemical peels. PIE may gradually fade with time and sun protection, while persistent redness can sometimes be treated with vascular devices.
For pigment-dominant post-acne marks, see chemical peel for pigmentation.
Acne Scar Treatment by Scar Type
| Scar / Mark Type | Commonly Considered Options | Important Limitation |
|---|---|---|
| Ice-pick scars | Focal chemical reconstruction, punch techniques, selected laser resurfacing | Microneedling alone may not adequately reach very deep narrow scars |
| Boxcar scars | Microneedling, RF microneedling, fractional laser, selected focal procedures | Deep sharply edged scars may need more targeted treatment |
| Rolling scars | Subcision, microneedling or RF microneedling, selected fillers | Tethering often needs to be addressed rather than treating only the surface |
| Hypertrophic scars | Silicone, intralesional treatment, selected vascular laser | Aggressive resurfacing can worsen some raised scars |
| Keloids | Specialist scar management with multimodal treatment | Recurrence is common and treatment must be individualised |
| PIH | Topical pigment treatment, photoprotection, selected superficial peels | Over-irritation can worsen pigmentation |
| PIE | Time, sun protection, inflammation control, selected vascular treatment | Pigment-targeting treatments may not address vascular redness |
How Acne Scars Treatment Works
Acne scar treatments work through different mechanisms. Some stimulate collagen remodelling, some release tethered scar tissue, some resurface the skin, and others target pigment or vascular changes rather than the scar itself.
| Mechanism | Examples | What It Targets |
|---|---|---|
| Controlled collagen remodelling | Microneedling, RF microneedling, fractional laser | Selected depressed scars and textural irregularity |
| Scar release | Subcision | Tethered rolling scars |
| Focal chemical reconstruction | TCA CROSS in selected scars | Narrow deep scars such as some ice-pick scars |
| Surface exfoliation | Superficial chemical peel | PIH, mild surface roughness, and uneven tone |
| Volume replacement | Selected dermal fillers | Specific depressed scars or volume deficits |
| Pigment control | Topical agents and selected peel protocols | Post-inflammatory hyperpigmentation |
| Vascular targeting | Selected vascular lasers | Persistent redness or vascular components of raised scars |
No single mechanism treats every scar type. Mixed scarring often needs a staged combination plan rather than one aggressive procedure.
How to Get Started with Acne Scars Treatment
The first step is to separate active acne from the scars and marks it has already left behind. Ongoing inflammatory acne can continue to create new scars, so acne control is usually an important part of the treatment plan before or alongside scar procedures.
Step 1: Identify the Main Concern
Look at whether the skin change is depressed, raised, brown or grey, red or pink, or a combination. A dermatologist can identify scar morphology more accurately under directional lighting and can distinguish scars from enlarged pores, active acne, or pigmentation.
Step 2: Control Active Acne
Moderate or severe active inflammatory acne should be treated appropriately so that new scarring is not continuously forming. This does not mean every patient must wait until there is never another pimple before any scar care can begin; timing depends on the treatment and the degree of active inflammation.
Step 3: Review Skin Tone and Pigment Risk
Darker and pigment-prone skin can still be treated successfully, but procedures that create excessive inflammation can trigger PIH. Treatment intensity, device selection, pretreatment skin condition, and aftercare all matter.
Step 4: Review Medicines and Previous Procedures
Tell the clinician about isotretinoin, prescription retinoids, anticoagulants, immunosuppressive medicines, previous keloids, herpes history, recent peels or lasers, and any previous scar treatments. Older blanket rules requiring every patient to wait six months after isotretinoin are not appropriate for every procedure; the timing should be individualised according to the treatment depth, dose, skin healing, and clinician assessment.
Step 5: Build a Staged Plan
Deep or mixed scars often respond best when the dominant scar type is treated first, followed by procedures that refine texture or pigmentation. Trying to perform every treatment at once can increase inflammation without improving results.
Key Benefits of Acne Scars Treatment
The realistic goal is to make scars less visible, soften transitions between scarred and normal skin, and improve colour or texture where possible. Complete scar erasure cannot be guaranteed.
- Improvement in the depth or edges of selected atrophic scars
- Smoother overall skin texture
- Reduction in the visibility of tethered rolling scars after appropriate release
- Flattening or softening of selected raised scars
- Reduction in post-acne pigmentation or persistent redness
- Improved confidence when visible scarring has been distressing

Acne Scars Treatment vs. Alternatives: An Honest Comparison
Acne scar treatment ranges from home skincare for flat post-acne marks to procedures for structural scarring. The best option depends on the problem being treated rather than on which treatment is most expensive or aggressive.
| Treatment | Main Role | Often Considered For | Limitations / Risks |
|---|---|---|---|
| Topical skincare | Controls acne, pigment and photo-damage | PIH, mild uneven tone, prevention of new acne | Does not lift deep structural scars |
| Superficial chemical peels | Controlled exfoliation | PIH and mild surface irregularity | Irritation can worsen PIH; not a primary treatment for deep scars |
| Microneedling | Collagen remodelling | Selected rolling and boxcar scars | Multiple sessions may be needed; unsuitable over active infection or significant inflammation |
| RF microneedling | Needling plus controlled radiofrequency energy | Selected moderate atrophic scars and texture | Operator- and device-dependent; inflammation and pigment change can occur |
| Fractional laser | Fractional resurfacing and collagen remodelling | Selected moderate or deeper atrophic scars | Downtime and PIH risk can be greater, especially in pigment-prone skin |
| Subcision | Releases tethering below the skin | Rolling scars | Bruising, swelling and other procedure-specific risks; does not treat every scar type |
| Dermal filler | Temporarily replaces volume | Selected depressed scars | Temporary; vascular complications are possible and require a qualified injector |
| Raised-scar therapy | Reduces excess scar tissue | Hypertrophic and keloid scars | Keloids can recur and usually need specialist management |
Acne Scars Treatment Results: What to Expect
Results are gradual because collagen remodelling and scar maturation take time. The timeline varies widely depending on scar type, procedure, treatment intensity, age of the scars, active acne, and skin response.
| Stage | What You May Notice | Important Note |
|---|---|---|
| First days after a procedure | Temporary redness, swelling, dryness, peeling, or bruising depending on treatment | This is recovery, not the final scar result |
| First several weeks | Surface texture or pigmentation may begin to improve | Structural scar remodelling is still early |
| Following months | Scar edges may soften and collagen-related improvement can become more apparent | Results often accumulate across a treatment course |
| Longer-term follow-up | Remodelling can continue after the final procedure | Maintenance mainly focuses on acne control, photoprotection, and pigment prevention |
What Affects Outcomes?
- Scar morphology: Shallow scars and deep tethered scars need different strategies.
- Skin tone: Pigment-prone skin may need a more conservative approach.
- Active acne: Ongoing inflammation can create new marks and scars.
- Age of the scar: Older scars can still improve, but response varies.
- Treatment choice: Matching the procedure to the scar type matters more than choosing the most aggressive option.
- Aftercare: Picking, excessive sun exposure, and overuse of irritating actives can worsen PIH and recovery.
Acne Scars Treatment Side Effects and Risks
Risks depend on the procedure. Redness, swelling, dryness, sensitivity, bruising, or temporary darkening can occur after many scar treatments. More aggressive treatments can carry greater risks such as PIH, hypopigmentation, infection, prolonged inflammation, scarring, or delayed healing.
Procedure-Specific Considerations
- Microneedling and RF microneedling: Temporary redness and swelling are common; infection, prolonged inflammation, pigment change, or scarring are possible if treatment is overly aggressive or performed on unsuitable skin.
- Chemical peels: Irritation, prolonged redness, PIH, hypopigmentation, chemical burns, infection, and scarring can occur depending on peel depth and skin response.
- Fractional laser: Redness, swelling, crusting, pigment change, infection, and prolonged recovery are possible. PIH is particularly important in darker or pigment-prone skin.
- Subcision: Bruising, swelling, tenderness, hematoma, temporary contour changes, and other procedure-specific complications can occur.
- Dermal fillers: Swelling, bruising, lumps, asymmetry, infection, and vascular occlusion are possible. Severe escalating pain, blanching, mottled or dusky skin, cold skin, blistering, or visual symptoms require urgent assessment.
- Keloid treatment: Recurrence, skin thinning, pigment change, and treatment-specific adverse effects can occur depending on the therapy used.
For additional information about peel-related complications, see chemical peel side effects.
When to Seek Prompt Medical Review
Contact the treating clinician for severe or worsening pain, rapidly increasing swelling, spreading redness, pus, fever, blistering, deep crusting, delayed healing, significant pigment change, or signs that a treated area is becoming infected. After filler treatment, severe pain, blanching, mottled skin, cold skin, or visual symptoms require urgent medical assessment.
Is Acne Scars Treatment Right for You?
| May Be Considered If | Needs Caution or Specialist Review |
|---|---|
| You have stable atrophic scars, raised scars, or persistent post-acne marks | You have significant active inflammatory acne in the treatment area |
| You understand that improvement is gradual and complete removal is unlikely | You have active infection, eczema, dermatitis, or open skin |
| You are willing to use sunscreen and follow aftercare | You have a strong keloid tendency and are considering procedures that can provoke new scarring |
| You are willing to use a treatment matched to your scar type | You are taking isotretinoin or other medicines that require procedure-specific review |
| You can attend follow-up and allow appropriate recovery | You are pregnant or breastfeeding and a planned medicine or procedure needs a safety review |
Pregnancy and breastfeeding do not make every aspect of acne scar care impossible, but prescription retinoids and many elective procedures are avoided or postponed. Treatment should be reviewed individually rather than applying a blanket rule to every option.
Expert Tips
- Treat the scar type you actually have rather than treating every post-acne mark as the same problem.
- Control significant active acne so new scars are not continuously forming.
- Do not expect topical products to fill deep structural scars.
- Do not choose the deepest peel or strongest laser because the scar looks severe; excessive inflammation can worsen pigmentation and scarring.
- For rolling scars, ask whether tethering needs to be addressed before relying on resurfacing alone.
- For darker or pigment-prone skin, discuss PIH prevention and conservative treatment settings.
- Introduce retinoids and exfoliating products gradually and do not stack multiple irritating actives around procedures without clinician guidance.
- Use daily broad-spectrum sunscreen and avoid picking or scratching healing skin.
- Do not stop prescribed medicines, including anticoagulants, solely to prepare for a cosmetic procedure without guidance from the prescribing clinician.
When Should You See a Dermatologist?
A dermatologist can help when scars are deep, mixed, raised, associated with active acne, or causing significant distress, or when home treatment is not improving flat post-acne marks. Professional assessment is especially useful before lasers, subcision, TCA CROSS, injectable treatments, or treatment of keloids and complex scarring.
