Keloid
Keloid
Keloid is a type of raised scar that extends beyond the original injury site. These scars can form on any part of the body; however, they are most commonly found on the chest, shoulders, earlobes, and cheeks. They can affect both men and women, although people with darker skin are more susceptible.
A keloid forms due to an excessive production of collagen during the healing process. When the skin is injured, the body works to repair the wound by producing fibrous tissue known as scar tissue. In some cases, the body over-produces this tissue, resulting in a keloid. They are generally not harmful to one's health but can cause discomfort and become a cosmetic concern for many.
Characteristics of Keloid
A keloid is usually characterized by its raised, shiny, and dome-shaped appearance. The texture can vary from rubbery to hard, and they are often itchy or even painful. The colour of a keloid can range from red to pink to a darker hue, particularly in darker-skinned individuals. Unlike regular scars, a keloid does not regress spontaneously and tends to increase in size over time.
Causes of Keloid Formation
Several factors can contribute to the formation of keloids. These include:
- Genetic predisposition. Individuals with a family history of keloids are more likely to develop them.
- Skin tension. Areas of the body that experience higher tension are at an increased risk.
- Trauma or surgery. Injuries, surgical procedures, vaccinations, or even acne can trigger keloid formation.
- Infections and inflammation. Wounds infected or inflamed during healing are more likely to form keloids.
Although the exact cause of keloid formation is not entirely understood, these factors can increase the likelihood of their development.

Treatment Options for Keloids
Treating keloids can be challenging. Various methods are available, and the effectiveness can differ from person to person. Some popular treatments include:
- Corticosteroid injections. These are often administered directly into the keloid to reduce inflammation and shrink the scar.
- Surgery. Surgical removal can be an option, though there's a significant risk of recurrence.
- Laser therapy. This method can help flatten keloids and reduce redness.
- Silicone gel sheets. These are placed on the scar and worn for several hours each day to flatten and fade the keloid.
- Pressure garments. Often used for burn scars, these garments exert pressure to reduce keloid size.
In addition to these treatments, new and emerging techniques are continuously being researched. These include cryotherapy and radiation therapy, among others.
Prevention of Keloid Formation
Preventing keloid formation can be challenging, particularly for individuals with a genetic predisposition. Some preventive measures include:
- Avoiding unnecessary trauma or surgery. Limiting elective surgeries or injuries can reduce the risk.
- Treating wounds promptly. Keeping wounds clean and applying an appropriate dressing can decrease inflammation and keloid risk.
- Using pressure garments and silicone gel sheets on fresh scars.
These measures may not completely prevent keloids but can significantly reduce the likelihood of their formation.
Lifestyle and Home Remedies
Several home remedies and lifestyle changes can help manage the symptoms associated with keloids, such as itching and discomfort:
- Moisturising regularly. Using creams and lotions can help keep the skin hydrated, reducing itchiness.
- Gentle massage. Massaging the keloid with oils such as coconut or vitamin E oil can improve its texture.
- Applying onion extract. Some studies suggest that onion extract can help reduce scar height and discomfort.
Although these remedies are not a substitute for professional treatment, they can provide supplementary relief.
Consulting a Healthcare Professional
If you believe you have a keloid, it is crucial to consult a healthcare professional. They can provide a personalized diagnosis and recommend the most effective treatment options. While keloids are often not a severe medical issue, professional advice is essential for managing and treating them appropriately.
Conclusion
Keloids are a common skin concern but understanding their characteristics and treatment options can help in managing them effectively. Though they may pose a cosmetic challenge, various treatments can alleviate symptoms and reduce their appearance. Consult with a healthcare professional for personalized advice and treatment plans.
