“Keloid Scars” is different from “Hypertrophic Scars”. Hypertrophic scars are caused by deeper tissue wounds (such as scars after surgery). Scar tissue appear during the healing process. Collagen overgrowth causes the scar to appear slightly convex, the color becomes darker, but the overgrowth is confined to the original wound, does not extend outward, and the scar have a chance to gradually settle over time.
In contrast, keloid scars are firm, smooth, hard growths that result from spontaneous scar formation. They can arise soon after an injury or develop months later. Keloids may be uncomfortable or itchy and may grow much larger than the original wound. They can form on any part of the body, although the upper chest and shoulders are especially prone to them.
The precise reason that wound healing sometimes leads to keloid formation is not fully understood but may be influenced by genetics. While most people never form keloids, others develop them after minor injuries, burns, insect bites, and acne spots. People with darker skin tend to form keloids more easily than Caucasians.
Treatment Options:
- Intralesional Steroid Injections
Intralesional steroid injections can be used to improve both hypertrophic and keloid scars. Steroids help absorb excessive collagen while inhibiting further collagen production. Patients typically receive injections every three to four weeks for about half a year. This method is suitable for patients who do not respond well to silicone gel sheets, though it may not be ideal for larger scar areas. The treatment is efficient, with a success rate of around 80%. - Vbeam Laser (Pulsed Dye Laser)
Another effective treatment for hypertrophic and keloid scars is the Vbeam laser, also known as a pulsed dye laser. This laser targets the blood vessels within the scar tissue, reducing redness, flattening the scar, and minimizing itching or discomfort. The laser works by emitting a concentrated beam of light that is absorbed by the blood vessels in the scar, ultimately shrinking the scar and preventing further growth. Vbeam is particularly beneficial in early-stage scars and can significantly improve the appearance of keloids and hypertrophic scars after several sessions. Patients usually undergo treatments at intervals of 4 to 6 weeks, and the therapy is well-tolerated with minimal discomfort.
These treatments, either used individually or in combination, can greatly enhance scar appearance and patient comfort. However, it is essential to consult with us to determine the most appropriate treatment based on the scar’s characteristics.
