Quick Answer: A hypertrophic scar is a raised, erythematous scar type that remains within the original wound boundaries, resulting from disrupted collagen synthesis during wound healing. Its key distinction from a keloid is that it does not extend beyond the wound margins. First-line treatment is intralesional triamcinolone injection and silicone gel application; adding fractional laser to this combination markedly improves the response.Hypertrophic scars are a common complication of surgical or burn injuries, particularly in the chest, shoulder, and chin regions. In addition to cosmetic concerns, they can also cause functional problems such as itching, pain, and restricted movement. Early intervention is the single most critical factor directly influencing treatment success. At Abel Beauty, we offer a comprehensive approach to scar treatment in Izmit–Kocaeli using combined protocols.
What Is a Hypertrophic Scar? Mechanism of Formation
Normal wound healing encompasses the phases of haemostasis, inflammation, proliferation, and remodelling. The remodelling phase lasts 12–18 months, during which collagen is both synthesised and degraded. In a hypertrophic scar, this balance is disrupted:
- Overproduction of TGF-β1 and TGF-β2 → permanently activates fibroblasts.
- As type III collagen synthesis increases, the collagen I/III ratio shifts; irregularly cross-linked collagen bundles form.
- The longer myofibroblast activation persists, the greater the wound contraction — the scar remains raised.
Hypertrophic Scar vs Keloid: Comparison Table
| Feature | Hypertrophic Scar | Keloid |
|---|---|---|
| Wound Boundaries | Does not exceed them | Exceeds them (extends to surrounding normal skin) |
| Growth | Limited; may flatten over time | May continue growing for years |
| Spontaneous Resolution | Possible (~50% — especially when tension decreases) | Rare |
| Location | Can occur anywhere | Chest, ear, shoulder, jaw, back |
| Family History | Absent or weak | Frequent (50%) |
| Skin Type | Equal frequency across all skin types | 5–15 times more common in darker skin tones |
| Itching/Pain | Moderate | Pronounced; spontaneous pain may occur |
| Treatment Response | Good to moderate | Difficult; high tendency to recur |
High-Risk Locations
Not every wound forms a hypertrophic scar. Risk is directly proportional to wound tension and dermal stress. Highest-risk areas include:
- Chest/sternum region: Respiratory movements create constant tension; hypertrophic scars are common in sternotomy wounds.
- Shoulder and deltoid region: Wide range of motion; continuous tension.
- Jaw and neck: Tension is generated by speaking and swallowing movements.
- Earlobe: Piercing site — one of the highest-risk areas for keloid as well.
- Over joints: Elbow, knee — continuous stress during movement.
Treatment Options: Comprehensive Comparison
| Treatment | Efficacy | Application Protocol | Side Effects | Priority |
|---|---|---|---|---|
| Silicone Gel / Sheet | High (preventive and therapeutic) | 12+ hours/day, 3–6 months | Minimal; irritation rare | First-line (early phase) |
| Intralesional Triamcinolone | High (50–100% improvement) | 10–40 mg/mL, every 4–6 weeks, 3–5 sessions | Atrophy, telangiectasia, hypopigmentation | First-line (active scar) |
| Fractional Laser (CO2 / Er:YAG) | High (tissue remodelling) | Every 6–8 weeks, 3–6 sessions | Redness 3–7 days, PIH risk | Second-line (combined with steroid) |
| Pulsed Dye Laser (PDL – 585/595 nm) | Moderate to high (vascular target) | Every 4–6 weeks, 3–5 sessions | Temporary bruising | For erythematous/vascular active scars |
| Cryotherapy | Moderate; effective for small scars | 10–30 sec, every 4–6 weeks | Pain, hypopigmentation | Keloid + small hypertrophic scar |
| Intralesional 5-FU | Moderate to high; for steroid-resistant cases | 50 mg/mL, every 4 weeks, 3–6 sessions | Local ulceration rare | Steroid-resistant or combination |
| Intralesional Verapamil | Moderate; collagen synthesis inhibitor | 2.5 mg/mL, every 2 weeks | Minimal | Alternative when steroid is insufficient |
| Pressure Therapy | Moderate; particularly effective for burn scars | ≥23 mmHg, 23 hours/day, 6–12 months | Comfort issues; compliance problems | Large-area burn scars |
Combined Protocol: Steroid + Laser Synergy
Single-modality treatment yields limited responses for moderate-to-large hypertrophic scars. The Abel Beauty combined protocol:
- In the same session: Fractional laser application → immediately followed by intralesional triamcinolone injection. After the laser perforates the scar tissue with microchannels, the steroid distributes more deeply and homogeneously.
- Silicone gel: Applied for 12+ hours per day between sessions; supports repair after laser treatment.
- Where indicated: PDL or 5-FU augmentation may be added at specific sessions.
- Session interval: 4–6 weeks; total of 4–6 sessions.
This protocol achieves 60–80% volume reduction, colour normalisation, and resolution of itching and pain.
Early vs Late Scar Treatment
Timing is critically important:
- Early intervention (4–8 weeks after wound closure): Silicone gel is started. The onset of hypertrophy is monitored. If erythema persists, PDL may be added. Intervention during this period can prevent the formation of a fully mature scar.
- Active scar (3–12 months): Steroid + laser combined protocol. Because the scar is still active (red, raised, itchy), the response to treatment is highest during this period.
- Mature scar (12 months+): The scar has faded and hardened. Fractional laser triggers tissue remodelling; however, the steroid effect diminishes. Surgical scar revision may become more feasible at this stage.
Scar Prevention: Post-Procedure Care Protocol
A protocol aimed at preventing hypertrophic scar formation in patients who have undergone surgery or sustained a deep laceration:
- Immediately after suture removal (days 7–14): Silicone gel application is initiated.
- Tension reduction: Perpendicular traction on the wound line is prevented with a scar-management bandage or medical tape.
- UV protection: SPF 50+ is applied throughout wound healing; sun exposure accelerates hypertrophy.
- Massage: Circular massage over the silicone (2 × 5 minutes per day) supports collagen remodelling.
- Follow-up: Check-up every 4–6 weeks; immediate intervention if hypertrophy begins.
Preventing Recurrence
The greatest challenge in hypertrophic scarring is recurrence; return of the scar can be seen particularly between months 6 and 12 after steroid treatment ends. To prevent recurrence:
- Silicone gel should be continued for at least 6 months after clinical treatment ends.
- Elimination of sources of tension (inappropriate activity, poor suture planning).
- Annual check-up sessions for early detection of re-activation.
- Patients with darker skin tones (Fitzpatrick IV+) have a higher recurrence risk; more frequent monitoring is recommended.
Frequently Asked Questions
Can a hypertrophic scar be removed with surgery? Scar resection (surgical removal) is only indicated if the causative factors of the existing scar are eliminated; otherwise, a new scar generally re-forms at the same site.
Is botulinum toxin used in scar treatment? Yes; intralesional botulinum toxin A can suppress collagen synthesis by reducing myofibroblast activity. It can be used as an adjunct modality, particularly in high-tension areas.
How many sessions are needed before results are seen? The initial response (softening, colour lightening) is generally observed after 2–3 sessions. A complete protocol requires 4–6 sessions.
