A keloid is an overgrowth of scar tissue that forms at the site of an injury. Unlike normal scars, keloids can continue to grow over time and may become raised, firm, and often itchy or painful. At Skinsol Dermatology, we offer keloid injections as an effective treatment to reduce the size, pain, and discomfort associated with these scars.
What Are Keloids?
Keloids are raised scars that result from an overproduction of collagen during the healing process. They can develop after skin injuries like cuts, burns, insect bites, or even piercings. Unlike normal scars, keloids extend beyond the boundaries of the original injury and can cause cosmetic concerns or discomfort due to their size and location. Common areas for keloids include the chest, shoulders, earlobes, and back.
Causes and Risk Factors
The exact cause of keloid formation is not fully understood, but it is believed to be due to an overproduction of collagen during the healing process. Some of the key factors that contribute to the development of keloids include:
Genetics: Family history plays a significant role in the development of keloids. If one or both parents have keloids, the likelihood of developing them increases.
Skin type: Keloids are more common in individuals with darker skin tones.
Age: People between the ages of 10 and 30 are more likely to develop keloids.
Location of injury: Keloids tend to form in areas where the skin is more prone to tension or movement, such as the chest, back, and shoulders.
Diagnosis
Diagnosing a keloid typically involves a visual examination of the affected area. In some cases, your dermatologist may inquire about your medical history, previous injuries, or family history of keloids. If necessary, a biopsy may be performed to confirm the diagnosis and rule out other skin conditions that may mimic keloids.
Treatment: Keloid Injections
The primary goal of keloid treatment is to reduce the size of the scar, alleviate symptoms such as itching or pain, and improve the cosmetic appearance of the skin. Keloid injections are one of the most effective treatments for reducing the size and symptoms of keloids. The most common injection treatments include:
Corticosteroid injections: These injections are used to reduce inflammation and flatten the keloid. They can also help to decrease pain and itching associated with the scar.
5-Fluorouracil (5-FU) injections: This medication is sometimes used in combination with corticosteroid injections to prevent keloid growth and improve the appearance of the scar.
Interferon injections: In some cases, interferon may be used to slow the growth of keloid tissue and reduce its appearance.
Collagenase injections: These injections work by breaking down the excess collagen in the keloid, helping to soften and flatten the scar over time.
Prevention and Aftercare
While it may not be possible to prevent keloids from forming, there are several steps you can take to minimize their appearance and manage them effectively:
Follow post-treatment care: After receiving keloid injections, it’s important to follow your dermatologist’s aftercare instructions. This may include avoiding sun exposure, using moisturizers, and applying silicone sheets to the area.
Avoid injury: Avoid unnecessary skin injuries, as even minor cuts or scratches can lead to the formation of keloids.
Monitor for changes: Keep track of any changes in the keloid size or appearance and schedule regular follow-up visits with your dermatologist for continued care and monitoring.
