Advanced Keloid and Scar Therapy: Restoring Skin at Aesthetic Hub, Dhaka
The skin’s remarkable ability to heal itself after injury, surgery, or acne is a fundamental biological process. However, this process can sometimes go awry, leading to scars that are more than just a memory—they can be raised, discolored, itchy, or painful, significantly impacting self-confidence and quality of life. Unlike regular scars, keloids represent an aggressive over-healing response. At Aesthetic Hub in Dhaka, under the pioneering care of Dr. Israt Jahan, keloid and scar therapy is not a one-size-fits-all solution but a sophisticated, multi-modal medical discipline. This guide explores the science of scarring and the advanced treatments available to restore your skin’s smooth, natural appearance.
Understanding Scar Biology: The Root of the Problem
To treat scars effectively, one must first understand how they form. After an injury, the body produces collagen to repair the wound. The balance and organization of this collagen determine the final scar.
Types of Abnormal Scars:
- Keloids: These are benign fibrous growths that extend beyond the original wound borders. They result from an exaggerated fibroblast response, causing excessive collagen production that fails to stop. Genetically predisposed individuals (often with darker skin tones, Fitzpatrick IV-VI) are most susceptible.
- Hypertrophic Scars: These are raised, red scars that stay confined to the wound area. They are caused by an overactive but ultimately controlled healing process and often improve over time, unlike keloids.
- Atrophic Scars: These are sunken or pitted scars, commonly from acne or chickenpox, caused by a loss of underlying collagen and fat during healing.
- Contracture Scars: These are scars that tighten skin, potentially restricting movement, often resulting from burns.
The Aesthetic Hub Diagnostic Protocol: Precision Before Procedure
Successful treatment begins with an accurate diagnosis. Dr. Israt Jahan employs a thorough assessment:
- Clinical Evaluation: Assessing scar type, size, maturity, texture, and symptoms (itch/pain).
- Patient History: Identifying genetic predisposition, past trauma, and previous treatments.
- Skin Typing: Crucial for choosing lasers and predicting healing, especially for South Asian skin prone to post-inflammatory hyperpigmentation (PIH).
This diagnosis directly informs the customized treatment plan.
The Multimodal Treatment Arsenal at Aesthetic Hub
Recognizing that complex scars require a combination approach, Aesthetic Hub employs a strategic toolkit of advanced therapies.
First-Line Therapy: Intralesional Injections
- Corticosteroid Injections (Triamcinolone): The gold standard for keloids and hypertrophic scars. Injected directly into the scar, they powerfully reduce inflammation, flatten the scar, and alleviate itching. Typically, a series of injections every 4-6 weeks is required.
- Combination Injections (5-Fluorouracil + Steroids): For resistant keloids. 5-FU, a chemotherapy agent, inhibits fibroblast proliferation. Used with steroids, it enhances efficacy and reduces steroid side effects like skin thinning.
Advanced Energy-Based Treatments
- Fractional Laser Resurfacing (CO2/Erbium): This is a cornerstone of modern scar therapy. The laser creates microscopic treatment zones, removing old, disorganized scar tissue and stimulating the body to produce new, healthy collagen. It is exceptionally effective for textural improvement in all scar types.
- Pulsed Dye Laser (PDL): Primarily targets the redness (erythema) and vascularity of young, red hypertrophic scars and keloids. It calms the overactive blood supply that fuels scar growth.
Regenerative and Minimally Invasive Techniques
- Microneedling with PRP (Platelet-Rich Plasma): Microneedling creates controlled micro-injuries to break up old scar collagen. When combined with PRP—a concentrate of the patient’s own growth factors—it powerfully stimulates organized collagen remodeling. Ideal for atrophic acne scars and early hypertrophic scars.
- Radiofrequency (RF) Microneedling: A significant advancement. Insulated needles deliver RF energy deep into the dermis, generating heat that causes immediate collagen contraction and long-term neocollagenesis. Excellent for improving scar pliability and texture with minimal epidermal damage.
Adjunctive and Surgical Therapies
- Silicone Gel Sheets & Ointments: A foundational, evidence-based therapy. Silicone creates a protective barrier, hydrates the scar, and modulates collagen production. It is most effective for prevention and treatment of early hypertrophic scars.
- Surgical Excision with Adjuvant Therapy: For large, bulky keloids, surgical removal may be considered. However, surgery alone has a high recurrence rate (>80%). At Aesthetic Hub, it is always followed immediately by preventive measures like post-op steroid injections or radiation therapy to block the aggressive re-scarring cycle.
- Cryotherapy: Using extreme cold (liquid nitrogen) to freeze and destroy keloid tissue. Often used for smaller keloids or in combination with injections.
The Integrated Treatment Strategy: A Sample Pathway
A patient’s journey is tailored. For example:
- A young, red hypertrophic scar: May start with PDL laser to reduce redness, followed by Fractional Laser for texture, supported by silicone gel.
- A mature, raised keloid: Likely begins with a series of intralesional steroid/5-FU injections to flatten it, followed by RF Microneedling to remodel the remaining tissue.
- Atrophic acne scarring: Would benefit from a series of Fractional Laser or Microneedling with PRP sessions.
Why Aesthetic Hub in Dhaka Stands Apart
- Medical Expertise Over Cosmetic Approach: Led by Dr. Israt Jahan, treatment is grounded in dermatopathology and evidence-based medicine.
- Technology for Darker Skin Tones: Specialized protocols using safe wavelengths (like Nd:YAG) prevent PIH, a critical consideration for Bangladeshi skin.
- Focus on Recurrence Prevention: The clinic’s philosophy emphasizes long-term management and preventive strategies, especially for keloids.
- Holistic Care: Combines in-clinic procedures with prescribed home care (silicone, sun protection) for sustained results.
Realistic Expectations and Commitment
Scar revision is a process, not a quick fix. Significant improvement is the goal, not necessarily complete eradication. Multiple sessions over several months are standard. Patient compliance with post-treatment care and sun protection is non-negotiable for success.
A Path to Confidence
Keloids and problematic scars are challenging, but they are no longer untreatable. Through a precise diagnostic process and the strategic application of advanced, combined modalities, Aesthetic Hub in Dhaka offers a scientifically robust path to smoother, less visible, and more comfortable skin. This approach represents not just cosmetic improvement, but a restoration of skin health and personal confidence.

Frequently Asked Questions (FAQs)
1. What’s the main difference between a keloid and a regular scar?
A regular scar (hypertrophic) stays within the boundary of the original wound and may fade over time. A keloid is an overgrowth that spreads beyond the wound edges, behaving like a benign tumor. Keloids rarely improve on their own and have a high recurrence rate after treatment.
2. Is scar treatment painful?
Discomfort varies by procedure. Injections feel like a quick pinch. Laser and microneedling treatments are performed under topical numbing cream, so you’ll feel pressure and heat, not sharp pain. Your comfort is always prioritized.
3. How many sessions will I need?
This depends entirely on the scar type, size, and age. Keloids often require 4-8 injection sessions. Laser or microneedling for textural improvement typically needs 3-6 sessions spaced a month apart. A detailed plan is provided after your first consultation.
4. What is the downtime after treatment?
- Injections: Possible bruising/swelling for 2-3 days.
- Fractional Laser: 5-7 days of redness, swelling, and peeling (social downtime).
- Microneedling/RF: 24-48 hours of redness (like a sunburn).
- Pulsed Dye Laser: Bruising (purpura) for 7-10 days.
5. Are the results permanent?
For textural improvement (smoothing raised or pitted scars), results from collagen-remodeling treatments (laser, RF) are long-lasting. However, keloids have a tendency to recur, so long-term maintenance and preventive care are essential parts of management.
6. Can old, years-old scars be treated effectively?
Yes. While newer scars often respond more quickly, advanced technologies like fractional lasers and RF microneedling can significantly improve the texture and color of scars that are years or even decades old.
7. Is it safe for darker skin tones? Are there risks of darkening?
This is a critical consideration. At Aesthetic Hub, treatments are specifically chosen for safety on South Asian skin (Fitzpatrick IV-VI). Fractional Non-Ablative Lasers (e.g., 1540nm) and RF Microneedling carry a very low risk of post-inflammatory hyperpigmentation (PIH). Proper pre- and post-treatment skincare is also used to prevent darkening.
8. What is the most important thing I can do after treatment?
SUN PROTECTION. Newly healed skin is highly prone to hyperpigmentation if exposed to UV rays. Daily use of a broad-spectrum SPF 50+ sunscreen is absolutely mandatory for optimal results and to prevent complications.
9. Why choose Aesthetic Hub over a general dermatologist or beauty clinic?
- Specialization: Focus on complex scar and keloid management using a wide arsenal of technology.
- Advanced Technology: Access to both laser and non-laser (RF, PRP) modalities for a tailored approach.
- Medical Strategy: Treatment is based on scar biology, not just appearance, with a strong emphasis on preventing recurrence, especially for keloids.
