Keloid Scars
Keloid scars are raised, thick scars that form from excess collagen during healing, often extending beyond the original wound. They can appear shiny, firm, and range in colour from pink to brown, causing itching or discomfort. Commonly found on the chest, shoulders, and earlobes, they may result from injuries or skin trauma.
The Science Behind It
Keloid scars occur due to an overactive wound healing response, where the body produces too much collagen, leading to the formation of a raised, fibrous scar that extends beyond the original injury. This abnormal healing process involves the proliferation of fibroblasts and excess deposition of extracellular matrix components, including collagen. Genetic predisposition plays a role in keloid formation, making it more common in individuals with a family history of keloids or certain ethnic groups, particularly those with darker skin. The exact molecular mechanisms behind keloid formation are still being studied.
Keloid Scar Treatment Options at Scars & Lasers
Keloid scars are caused by an exaggerated healing response and often require combination therapy. At Scars & Lasers, treatment is tailored to scar activity, thickness, symptoms (pain/itch), colour, and response to prior therapies.
Why Combination Therapy Matters
Keloid scars rarely respond to a single treatment alone. Combining injections, vascular lasers, fractional lasers and drug delivery techniques allows us to:
- Calm inflammation
- Reduce abnormal collagen production
- Improve scar thickness, colour and symptoms
- Lower recurrence risk
Important Considerations
- Keloids cannot always be permanently removed, but they can usually be significantly improved and controlled
- Multiple treatments are often required
- Maintenance therapy may be needed for long-term control
- Treatment plans are individualised after clinical assessment
Consultation & Assessment
All keloid scars are assessed by our experienced laser dermatology team to determine:
- Scar activity and thickness
- Previous treatments and response
- Skin type and pigment risk
- Suitability for laser-based therapies
Frequently Asked Questions
A keloid scar is an overgrowth of scar tissue caused by excessive collagen production during healing. Unlike normal scars, keloids extend beyond the original injury and may continue to grow over time.
