Quick Answer
Scars are areas of fibrous tissue that replace normal skin following injury, surgery, acne, or inflammation. Scar treatment is not one-size-fits-all — candidacy depends on scar type, depth, and skin tone. At ID Cosmetic Clinic in Markham and Toronto, Dr. Dan Xu, M.D., personally assesses each case and may recommend options such as laser resurfacing, microneedling, or filler correction. Most scar improvement protocols involve multiple sessions spaced weeks apart, with gradual results visible over several months.

What Is Scar Revision? Why Do Different Scars Require Completely Different Approaches?
Scar revisionIt is not a matter of “one device fixes everything” — it is built onscar type, age, anatomical location, skin type, and patient goalsa multimodal medical protocol. Incorrect treatment can worsen scarring — making it thicker, redder, and itchier — and may even trigger keloid formation.
5 Key Facts About Scar Revision
scarCannot be completely eliminated — Can only improve, not eliminate
Any physician who promises “100% removal” is not being honest with you.The true goal is comprehensive improvement in texture, color, contour, and function, Most cases achieve 50–80% improvement. Realistic expectations are key to satisfaction.
Scar type determines the treatment plan — it is never a one-size-fits-all laser approach
Treatment of Atrophic (Depressed) and Hypertrophic (Raised) Scarscompletely opposite. Atrophic scars require stimulation of collagen regeneration; hypertrophic scars require suppression of excessive tissue overgrowth.Choosing the wrong protocol can make scarring worse..
Timing determines outcomes — early vs. late intervention
New scars (< 12 months) are in the remodeling phase — this is the optimal window for intervention.Older scars (> 2 years) respond more slowly, More sessions and a longer treatment timeline are required.Acne scar specifics — Scar treatment is not performed while active acne remains uncontrolled.
Asian skinPIH higher risk — Energy settings must not be too aggressive
Fitzpatrick IV–V Post-treatmentPIH (post-inflammatory hyperpigmentation)This is the #1 side effect. Excessive energy, inappropriate protocols, and inadequate sun protection can all trigger it. A dedicated Asian skin protocol is essential.
Combination therapy is what works — a single modality is rarely sufficient
When multiple acne scar subtypes coexist, a combination approach is required: Morpheus8® (rolling / boxcar scars) + TCA CROSS (ice-pick scars) + PRP (overall repair) + epidermal resurfacing.No single technique provides complete coverage, This is the fundamental reason why medspa treatments yield limited results.
Main Types of Scars
- Atrophic scars (atrophic) — Depressed · acne / chickenpox / trauma
- Hypertrophic scars (hypertrophic) — Raised · confined within the original wound boundary
- Keloid (keloid) — Raised · extending beyond the original wound boundaryContinued growth
- Contracture scars (contracture) — Burn / trauma · skin contracture
- Pigmented scars (PIH / erythema) — flat surface but abnormal discoloration
3 Common Subtypes of Acne Scars
Ice pick (most difficult to treat)
Narrow, deep (> 2 mm) pinhole-like depressions. Morpheus8 has limited effect · TCA CROSS chemical ablation is required.
Rolling (most common)
Broad, shallow, wave-like depressions caused by fibrous tethering. Morpheus8 + Subcision release delivers strong results.
Boxcar
Well-defined, square-edged depressions. Treated with a combination of Morpheus8 and targeted TCA Cross.
4 step preliminary self-assessment
- Your scar isDepressed or raised?
- scarHow long has it been (New vs. old)?
- Whether / Is thereStill reddening, itching, or growing?
- Whether there is / Do you haveFamily history of keloids?
⚠️ Scars that are still evolving require different treatment timing. Accurate subtype classification requiresClinical palpation + dermoscopy when indicated. Consultation with Dr. Xu completed.
5 Main Causes of Scar Formation
Understanding the mechanisms of scar formation is the foundation of both prevention and treatment — high-risk factors require specialized protective protocols.
Acne inflammation (most common cause)
In nodular and cystic acne, inflammation penetrates deep into the dermis,Disrupts collagen bands and subcutaneous fibrous septae, leading to permanent depressions. Mild acne tends to leave PIH (pigmented marks), while severe acne causes deeper atrophic scars.
Surgical incisions / traumatic lacerations
Caesarean section, appendectomy, traumatic wound closure, and similar procedures.High incision tension, location (chest / shoulder / joints), suture quality, infectionall affect scar quality.
Scalding / burn injury
Burn depth (second-degree or deeper) determines scar severity. Thermal, chemical, and electrical burns commonly result inextensive hypertrophy + contracture, Requires multi-modality, phased treatment.
Genetic predisposition + keloid-prone constitution
A strong family history of keloids is a known risk factor, with higher incidence in Asian and African-heritage individuals. Any skin injury can trigger keloid formation,Earlobes, chest, shoulders, and jawlineThese are high-risk anatomical zones.
Improper wound care (picking / incorrect products / early UV exposure)
Picking or squeezing acne worsens PIH and deepens depressions; using irritating products during the wound-healing phase impairs recovery; exposing new scars to UV radiation causesPermanent pigmentation.
Atrophic vs. hypertrophic vs. keloid vs. PIH
Treatment strategies for these four scar typescompletely opposite — Accurate subtype classification is the foundation of successful treatment.
Atrophic scars
| Appearance | Depressed · below the skin surface |
| Commonly seen in | Acne / chickenpox / trauma |
| Mechanism | Collagen degradation · dermal atrophy |
| Treatment core | stimulating collagen regeneration |
| Treatment plan | Morpheus8 · CROSS · Subcision · PRP |
Hypertrophic scars
| Appearance | Raised · red · confined |
| Commonly seen in | Burns / surgical incisions / traumatic wounds |
| Mechanism | excessive collagen deposition |
| Treatment core | suppressing hypertrophy + softening |
| Treatment plan | Corticosteroid + 5-FU · PDL · Silicone |
Keloid
| Appearance | Raised · extending beyond the original wound boundary |
| Commonly seen in | Genetic predisposition · chest / earlobes |
| Mechanism | Abnormal inflammation + continued growth |
| Treatment core | Sustained suppression · avoiding surgery |
| Treatment plan | Multiple rounds of corticosteroid + 5-FU · laser with caution |
PIH Pigmented scars
| Appearance | Flat · brown / red / tan discoloration |
| Commonly seen in | Post-acne · Common in Asian skin |
| Mechanism | Pigmentation · not true scar tissue |
| Treatment core | Fade pigmentation |
| Treatment plan | PicoSure Pro · Cyspera · Sun protection |
Why does scar treatment on Asian skin require extra care?
Scar treatment on Asian skin (Fitzpatrick III–V) carries a higher risk of post-inflammatory hyperpigmentation (PIH), a greater tendency toward keloid formation, and increased sensitivity to laser energy. This is a core area of expertise at ID Cosmetic Clinic.
1. PIH Is the #1 side effect
Post-procedure care for Asian skinPIH (post-inflammatory hyperpigmentation (PIH)) occurs in approximately 30–60% of cases, Significantly higher than in Caucasian patients at 5–10%. Incorrect laser energy, inappropriate resurfacing depth, and inadequate sun protection can all trigger it. Dr. Xu’s core safety principles:“Less is More” — Low energy, extended treatment intervals, intensive pre-procedure conditioning, and thorough post-procedure repair.
2. High-risk zones for keloid formation
Asian patientsEarlobes, chest, shoulders, and jawlineThese are high-risk zones for keloid formation. Any skin treatment in these areas requires careful judgment. For patients with a family history, Dr. XuNon-essential aesthetic procedures are not recommended in high-risk anatomical zones..
3. Acne scar characteristics: mixed subtypes + overlapping PIH
Asian clients with acne scars commonlyMultiple scar subtypes present simultaneously (Icepick + rolling + boxcar + PIH — no single technique can address all of these. Dr. Xu’s protocol typically combines:Morpheus8 Fractional resurfacing for rolling/boxcar scars + TCA Cross for icepick scars + PicoSure Pro for PIH + PRP for overall tissue repair.
Fitzpatrick × Scar Treatment Strategy
| Fitzpatrick | PIH Risk | Keloid risk | Energy strategy |
|---|---|---|---|
| II–III | Low | Low | Standard energy settings |
| III lighter Asian skin tone | Medium | Medium | Moderate energy + skin conditioning |
| IV Typical Asian | High | Moderate–high | Low energy + extended treatment intervals |
| V Deeper Asian skin tones | Very high | High | Ultra-low energy + test spot |
The most distressing outcome of scar treatment isAppearing worse after treatment than before. When treating scars on Asian skin, the physician’s ability to assess skin type and calibrate energy parameters matters far more than the device itself. In the hands of different practitioners, the same Morpheus8 platform can produce a 5–10× difference in PIH rates. — Dr. Dan Xu, M.D., CCFP
Combined Treatment Protocol for Scar Revision
There is no “best single treatment” — only the combination protocol best suited to your specific scar type.
Morpheus8 Radiofrequency microneedling First-line treatment for atrophic scars
Fractional radiofrequency microneedling penetrates up to 4 mm below the skin surface,Simultaneously stimulates dermal collagen regeneration and fibrous septae remodeling. Delivers significant results for rolling and boxcar acne scars as well as mild atrophic traumatic scars. Offers a safer profile on Asian skin compared to traditional fractional CO₂ laser.
- 3–4 sessions, spaced 4–6 weeks apart
- 3–5 days of mild redness
- Collagen regeneration continues for 6–12 months
TCA CROSS Chemical ablation (TCA CROSS) Specifically for ice pick scars
High-concentration TCA precisely applied to the base of ice pick scars,Induces localized collagen remodeling to elevate depressed areas. This is an ice pick scarThe only effective non-surgical approach.
- 2–4 sessions, spaced 6–8 weeks apart
- 7–10 Days of crusting
- Strict sun protection is required.
Subcision Subcision Adjunct treatment for rolling scars
mechanical subcutaneous release using a specialized blunt cannulafibrous bands tethering rolling scars, to elevate depressed scar tissue. Commonly combined with Morpheus8.
Combined corticosteroid + 5-FU injection First-line choice for hypertrophic scars and keloids
Triamcinolone (Kenalog) + 5-Fluorouracil (5-FU)Suppress excessive fibroblast proliferation, softening hypertrophic scars and keloids. More effective than corticosteroid aloneReduces the risk of hypopigmentation.
- Every 4 weeks × 3–6 sessions
- Same-day recovery after injection
Pulse Dye Laser (PDL) Red scars
595nm Pulsed dye laser selectively targets oxyhemoglobin,Reducing redness in hypertrophic scars + suppressing neovascularization, accelerating remodeling. Monthly protocol of 3–5 sessions.
PRP Microneedling / injectables Overall repair
Autologous platelet-rich plasma (PRP)Stimulates tissue regeneration + reduces PIH + accelerates healing. Commonly used as an overall regenerative complement across all scar treatment protocols.
PicoSure Pro 755nm (PIH Treatment)Pigmented scars
for PIH surrounding or associated withPIH Pigmented scars, PicoSure Pro A safe option for Asian skin. Fitzpatrick IV–V skin types require low-energy protocols.
Silicone sheets / silicone gel Prevention + maintenance
Medical-grade siliconeSustained occlusion + improved hydration environment, This is the gold standard for scar prevention and maintenance. A minimum of 6 months is recommended for new scars, and at least 12 months for hypertrophic scars.
Sample combination protocol
| Scar type | Recommended protocol |
|---|---|
| Acne scars · rolling + boxcar types predominate | Morpheus8 × 4 + Subcision + PRP × 3 |
| Acne scars · predominantly icepick type | TCA CROSS × 3 + Morpheus8 × 2 + PRP |
| Hypertrophic scars | Corticosteroid + 5-FU × 4 + PDL × 3 + silicone |
| C-section scar adhesion | Microneedling PRP × 3 + local injections + silicone |
| Keloid | Ongoing corticosteroid + 5-FU therapy + cautious use of laser |
| large-area burn scars | Staged approach: injections + Fraxel + long-term silicone |
How Does Dr. Xu Design a Scar Revision Protocol? (6-Step Process)
The greatest risk in scar treatment is applying the same device to every scar type without differentiation — and this is the fundamental difference between Dr. Xu’s approach and that of a typical medspa.
Detailed subtype classification assessment
- Scar type (atrophic / hypertrophic / keloid / PIH)
- Acne scar subtypes (Ice-pick / rolling / boxcar)
- Goodman-Baron Grading (I–IV grade)
- Vancouver Scar Scale (color / thickness / pliability / height)
- Scar age (< 6 months / 6–12 months / > 12 months)
Risk assessment
Performed by Dr. Xu:
- Fitzpatrick classification (PIH risk)
- Family history of keloids
- Previous responses to scar treatments
- whether acne is still in an active phase
- Anatomical risk zones (earlobes / chest / joints)
Timing assessment
This is a frequently overlooked yet critically important step:
- Acne scars: Acne must be controlled for at least 6 months before treatment begins
- Newly formed hypertrophic scar: Begin silicone therapy 2–8 weeks post-procedure / post-injury
- Old / established scars: Can begin at any time
- Red-phase scar: PDL Initial phase · wait for stabilization before addressing atrophy
Designing a 6-month / 12-month protocol
Not a “one-time solution” — it isComplete phase:
[Week 1]1st primary treatment session (type-specific)
[Week 5]2nd treatment session + mid-course assessment
[Week 9]3rd treatment session + adjunct therapies added as needed
[Week 13]4th treatment session + photographic comparison
[Month 6]Full-cycle assessment + second cycle if indicated
[maintenance]Assessment every 6 months + ongoing silicone therapy + sun protection
incremental adjustments at each follow-up
- Photo comparison (standardized lighting + consistent angle)
- Assess response from previous session (PIH signaling? Overreaction?)
- Fine-tune energy / concentration (Response too strong → reduce)
- Adjust adjunct treatment plan (PRP added when indicated)
- reinforced sun protection review
Prevention + maintenance
End of scar treatment ≠ end of the journey:
- Long-term silicone use (hypertrophic scars 12 months or older)
- Strict SPF 50+ (Scars older than 12 months)
- Ongoing acne control (To prevent new scarring)
- Retinol skincare (atrophic scar maintenance)
- Assessment every 6 months
Success in scar treatment is not “complete elimination” — it is “Moving from a state of distress to no longer being aware of it“. Setting realistic expectations is the first step in treatment. — Dr. Dan Xu, M.D.
How Soon Will Scar Treatment Show Results? How Many Sessions Are Needed? How Much Can It Improve?
Scar treatment is a 6–12 month commitment. The three tables below address the most frequently asked questions.
How soon can results be seen?
| Phase | timeline | Changes |
|---|---|---|
| After the 1st Morpheus8® session | 4–6 weeks | Initial collagen activation · improved texture on touch |
| After sessions 2–3 | 3 months | Visible texture improvement · shallower depressions |
| Full course of 4 sessions + 6 months | 6 months | Collagen regeneration peaks · significant overall improvement |
| Full protocol + 12-month maintenance | 12 months | Stabilized final outcome |
How many sessions are needed?
| Scar type | Recommended sessions | Total treatment cycle |
|---|---|---|
| Acne scars · Mild | Morpheus8 × 3 + PRP × 2 | 3 months |
| Acne Scars · Moderate to Severe | Morpheus8 × 4 + CROSS × 3 + PRP × 4 | 6–9 months |
| Hypertrophic scars | injections × 4–6 + PDL × 3 | 6 months |
| Keloid | Injections continued over 6–12 months | Long-term maintenance |
How much improvement is possible?
| Scar type | Typical degree of improvement |
|---|---|
| Rolling acne scars | 60–80% |
| Boxcar acne scars | 50–70% |
| Ice pick acne scars | 40–60% (most challenging) |
| Hypertrophic scars | 70–90% Improvement in raised texture |
| Keloid | 50–70% · However, long-term management is required. |
| PIH Pigmented scars | 70–90% |

The most frustrating part of scar treatment isTreatment makes the appearance worse, not better. The most common tragedy for Asian skin clients is being sold an aggressive high-energy laser treatment — with minimal scar improvement and widespread post-inflammatory hyperpigmentation (PIH) as a result.Multi-device combination + skin-type-adapted energy protocols, This is the core value of physician-led care. — Dr. Dan Xu, M.D.

Scar revision is not about “running a machine” — it’s about designing a multimodal treatment protocol.
The same scar treated with the wrong protocol can worsen PIH. Genuine improvement requires the right combination of devices and skin-type-calibrated energy settings. As a specialist in Asian skin, Dr. Xu brings clinical expertise in defining the safe boundaries of scar treatment.
About the Cost of Scar Revision
Scar revision is one of the widest-ranging and hardest-to-standardize areas in medical aesthetics. The most common question we hear is: “Why can quotes vary so much?” The answer lies inWho analyzes your scar subtypes, determines which devices to combine, assesses your PIH risk, and designs your 6–12 month treatment protocol. Two treatments may share the same name — “acne scar treatment” — yet the protocol complexity of Morpheus8 alone versus Morpheus8 + CROSS + PRP + PicoSure Pro is worlds apart. This isn’t about upselling; it’s because ice pick, rolling, boxcar, and PIH subtypes each require a different tool. Leave one out, and that subtype goes unaddressed.
Straightforward stable pigmented scars and mild rolling scars undergoing initial treatment may be managed by a trained aesthetic technician using standard protocols under Dr. Xu’s supervision; however,Mixed scar subtypes, Fitzpatrick IV–V high-risk skin, revision of failed treatments from other clinics, family history of keloids, extensive burn scars— these cases require deep physician involvement throughout every stage, from assessment and treatment design to each follow-up review. Injectable treatments (corticosteroid + 5-FU / PRP) are typically performed by the physician directly.
