Keloids
Keloids are raised overgrowths of scar tissue that develop at the site of a healed skin injury, such as a cut, burn, surgery, vaccination, acne, or piercing. Unlike normal scars, which typically remain within the boundaries of the original wound, keloids extend beyond the original injury site and can be larger and more noticeable.
The exact cause of keloids is not fully understood, but they are believed to result from an overproduction of collagen during the healing process. Certain factors may increase the risk of keloid formation, including:
- Genetics: Keloids tend to run in families, suggesting a genetic predisposition.
- Skin Type: People with darker skin tones are more prone to keloid formation.
- Age: Keloids are more common in young adults, with peak incidence occurring between ages 10 and 30.
- Location of Injury: Keloids are more likely to develop on areas of the body with less skin tension, such as the chest, shoulders, earlobes, and upper back.
Keloids are typically firm, smooth, shiny, and may range in color from pink to red to dark brown. They can be itchy, tender, or painful, and may continue to grow over time.
Treatment options for keloids include:
- Corticosteroid Injections: Injecting corticosteroids directly into the keloid can help reduce inflammation and flatten the scar.
- Surgical Removal: Surgical excision of the keloid followed by techniques to prevent recurrence, such as radiation therapy or compression therapy.
- Laser Therapy: Laser treatment can help reduce the size and color of keloids.
- Cryotherapy: Freezing the keloid with liquid nitrogen can help shrink it.
- Silicone Gel or Sheets: Applying silicone gel or sheets to the keloid may help flatten and soften the scar.
