Burn scars encompass a wide clinical spectrum, ranging from superficial burns to deep burns, and from small skin scars to contractures that restrict movement. These scars cause not only aesthetic but also functional problems; they directly affect the patient's psychological wellbeing, daily activities, and quality of life. At Virtuana Clinic in Izmit/Kocaeli, we apply evidence-based, current treatment protocols to burn scar patients from a multidisciplinary perspective.
Classification of Burn Scars
The type of scar that forms after a burn depends on the depth and location of the burn, the individual's wound healing tendency, and the initial treatment provided. The primary classification is as follows:
- Hypertrophic scar: Raised, red-pink, firm in structure, confined within scar boundaries; sensitive to touch; may show spontaneous regression within 1–2 years. Most commonly seen in burn scars.
- Keloid: Invasive tissue that extends beyond scar boundaries and continues to grow progressively; permanent; genetic predisposition is a key determinant. More prevalent in individuals of African and South Asian descent.
- Contracture scar: Bands forming at joints and flexion areas that cause restricted movement; severe cases require surgery.
- Atrophic (depressed) scar: Sunken appearance due to collagen loss in deep burns; frequently seen at graft sites.
- Depigmented scar: White/pale scar due to melanocyte loss; vitiligo-like appearance; requires pigmentation treatment.
Assessment of Burn Scar Severity: Vancouver and POSAS Scales
Standardised scar scoring tools are used for treatment decision-making and outcome monitoring:
- Vancouver Scar Scale (VSS): Four parameters — vascularity, pigmentation, pliability, and height; total score 0–13
- POSAS (Patient and Observer Scar Assessment Scale): Includes both physician and patient perspectives; two sub-scales each with six parameters; superior for monitoring treatment response
- Dermoscopy and 3D imaging: Objective measurement of scar vascularity and surface structure
At Virtuana Clinic, POSAS scoring is performed for every burn scar patient, and photographic documentation is maintained throughout all sessions prior to treatment.
Conservative Treatments: Silicone, Compression, Massage
Conservative methods, which form the first step of burn scar treatment, yield the most effective results during the scar remodelling period (0–2 years):
| Method | Mechanism | Application | Evidence Level |
|---|---|---|---|
| Silicone gel / wound dressing | Hydration, collagen regulation, MMP suppression | 12+ hours/day; 3–6 months | Level 1A — strong evidence |
| Compression garment | Pressure-mediated collagen fibril alignment, ischaemia | 20–30 mmHg; 23 hours/day; 6–24 months | Level 1B |
| Massage therapy | Mechanical dissolution of fibrous bands, circulation | Twice daily, 10–15 min; combined with compression | Level 2B |
| Physiotherapy / exercise | Contracture prevention, joint mobilisation | Should begin early; long-term | Level 1B (contracture) |
Intralesional Steroid Injection: Hypertrophic and Keloid Scars
Triamcinolone acetonide (TAC) injection is the most widely used pharmacological method for treating hypertrophic scars and keloids. Its mechanism is based on suppressing collagen synthesis, reducing fibroblast proliferation, and removing alpha-2 macroglobulin-mediated collagenase inhibition.
- Concentration: 10–40 mg/ml (titrated according to hypertrophic scar response)
- Frequency: Every 4–6 weeks, an average of 3–6 sessions
- Efficacy: 50–80% improvement in hypertrophic scars; 60–70% improvement in keloids; however, recurrence risk is 50%
- Combination with laser: PDL (pulsed dye laser) + steroid combination yields superior results compared to steroid injection alone
Complications: Atrophy, telangiectasia, hypopigmentation, and periscar fat atrophy; high concentrations and excessive injections should be avoided.
Fractional CO2 Laser: The Gold Standard for Burn Scars
Fractional ablative CO2 laser (10,600 nm) stimulates collagen remodelling in scar tissue by creating selective thermal coagulation columns (MTZ — micro-treatment zones). Approximately 20–30% of the skin surface is treated per session; the remaining healthy tissue facilitates healing. This fractional approach delivers the efficacy of fully ablative CO2 laser with a significantly safer healing profile.
Clinical evidence: Fractional CO2 laser treatment (average 3–5 sessions) for hypertrophic burn scars has been shown to achieve 40–60% improvement in the POSAS patient score (Burns, 2024). Significant improvement was achieved across all parameters of firmness, height, and colour.
Treatment parameters — pulse energy (mJ), density (% MTZ coverage), and number of passes — are personalised according to scar type, depth, and the patient's skin phototype.
Fractional Nd:YAG and Vascular Laser Combination
In addition to fractional ablative laser, non-ablative fractional laser systems (1550 nm, 1927 nm) offer alternatives requiring less downtime. These are particularly suitable for sensitive scars on the face and neck.
For hypertrophic burn scars with red-purple discolouration (vascularly active scars), PDL (pulsed dye laser, 595 nm) or Nd:YAG vascular laser provides simultaneous colour correction. The PDL + fractional CO2 combination offers more comprehensive improvement compared to CO2 laser alone; issues of colour, texture, and elevation are addressed together.
PRP (Platelet-Rich Plasma) and Biological Agents
PRP is a platelet concentrate derived from the patient's own blood. The growth factors it contains (PDGF, TGF-β, EGF, VEGF) support wound healing and collagen remodelling. Routes of PRP application in burn scar treatment:
- Intralesional PRP: Injection into hypertrophic scar tissue; currently being investigated as an alternative to steroids
- Topical PRP after laser: PRP infiltration into microchannels following fractional CO2 laser application; accelerates healing and potentiates results
- Microneedling (dermapen) + PRP: For volume restoration and tissue healing in atrophic burn scars
A meta-analysis published in 2023 demonstrated that PRP significantly improved Vancouver Scar Scale scores in burn scar treatment (p<0.05) and showed superiority over compression therapy alone.
Fat Grafting (Lipograft): Contour and Tissue Quality Restoration
Autologous fat transfer (lipograft) involves injecting the patient's own adipose tissue, harvested by liposuction, beneath the burn scar. The mechanism is multifaceted: in addition to its volumetric filling effect, the mesenchymal stem cells (ADSC — adipose-derived stem cells) within the adipose tissue improve tissue quality and scar pliability in the long term.
Ideal indications: Deep burn scars with contracture, atrophic and indurated scars on the face and neck, skin quality issues at graft sites. Sessions: An average of 2–3 sessions; since 30–50% of each injected volume is absorbed, the volume is adjusted per session.
Surgical Treatment: Contractures and Extensive Scars
When contractures resulting from deep burn injury and extensive hypertrophic scars are present, surgical options come into play:
- Z-plasty / W-plasty: Geometric disruption and reorientation of the contracture band; for linear scars restricting joint movement
- Tissue expander: Expansion of adjacent normal skin; for closure of large scar areas
- Split-thickness and full-thickness grafts: Primary closure of deep wounds; minimises scar formation
- Flaps: Local or distant flap closure of large scar areas; particularly for the face and hands
Treatment Timeline: Early vs. Late Phase
Timing in burn scar treatment directly influences treatment selection:
- 0–3 months (active wound healing phase): Silicone application, compression, massage; laser is not yet applied
- 3–6 months (early maturation phase): First intralesional steroid session can be administered; non-ablative fractional laser can be initiated
- 6–12 months (maturation phase): Fractional CO2 laser sessions can be planned; PRP combination can be added
- 12+ months (stabilisation phase): Fully ablative or combined protocols; fat grafting; surgical revision if necessary
The Importance of a Combined Approach in Burn Scar Treatment
No single method can address all dimensions of a burn scar (height, firmness, colour, tissue quality, pigmentation) on its own. The best outcomes are achieved with multimodal treatment protocols:
| Scar Type | Recommended Combination | Expected Outcome |
|---|---|---|
| Active red hypertrophic scar | PDL + steroid + silicone | Colour correction, height reduction |
| Stable hypertrophic scar | Fractional CO2 + PRP | Texture, firmness, and colour improvement |
| Atrophic / depressed burn scar | Lipograft + fractional CO2 | Volume restoration + skin quality improvement |
| Contracture scar | Surgery (Z-plasty) + CO2 laser + physiotherapy | Recovery of movement + scar improvement |
Virtuana Clinic Burn Scar Treatment Protocol
At our clinic in Kocaeli/Izmit, we apply the following approach to burn scar patients:
- Comprehensive assessment: POSAS scoring, dermoscopy, and photographic documentation
- Development of a stepwise treatment plan according to scar type and phase
- Active / early-phase scars: Silicone wound dressing prescription, compression and massage training
- Hypertrophic scar: Intralesional steroid — every 4–6 weeks
- PDL vascular laser when indicated (active red scars)
- Fractional CO2 laser sessions — every 6–8 weeks; PRP combination
- Lipograft or filler assessment for atrophic scars
- Plastic surgery consultation for contracture cases
Sun Protection and Burn Scar Care
Burn scars are highly sensitive to UV radiation. Melanocyte density in new scar tissue is variable; sun exposure can cause permanent hyperpigmentation or pigment irregularities. Therefore:
- SPF 50+ sunscreen should be applied daily to all scar areas being treated or healing
- Direct sun exposure should be avoided for at least 1 year; protective clothing is recommended
- Sun protection guidelines should be followed more strictly for 4–6 weeks after laser treatment
Frequently Asked Questions
Can burn scars disappear completely? Complete disappearance is not possible in every case; however, with the right treatment, appearance and function can be significantly improved. The goal is not a "normal appearance" but rather an "inconspicuous improvement" and functional restoration.
Up to what age can laser treatment be applied? There is no upper age limit. For the lower limit, stabilisation of the scar tissue and suitability for anaesthesia in children are considered; treatment is generally applicable from age 5 and above.
Can laser treatment correct contractures? In mild contractures, fractional laser can improve range of motion by increasing tissue elasticity. In severe contractures, laser alone is not sufficient; a combination with surgery is required.
