Keloid Scar Revision

What are keloids? What is keloid scarring?

Keloids are raised, fibrous scars that develop at the site of a healed injury or trauma to the skin. Unlike typical scars that gradually fade over time, keloids grow beyond the boundaries of the original wound and can become larger and more prominent over time. Common causes include burns, acne scars, piercings, surgeries, or tattoos. Individuals with darker skin tones have an increased risk of developing keloids in response to injury or trauma. Keloids tend to run in families, suggesting a genetic predisposition to the condition.

What are the treatment options for keloid scarring?

Treating keloids can be challenging, as they have a tendency to recur even after successful treatment. However, several treatment options are available to help improve the appearance and symptoms of keloids, including:

Pressure therapy involves applying pressure to keloids using specialized garments or dressings. This technique helps flatten keloids and reduce their size by inhibiting collagen production and promoting collagen breakdown.

Intralesional steroid injections are commonly used to reduce inflammation and flatten keloids.

5-flurouracil interferes with the growth of abnormal cells, including those involved in keloid formation.

Silicone gel or sheets can be applied directly to keloids to flatten and soften the scar tissue. These products help hydrate the skin and improve the appearance of keloids over time.

Surgical excision involves cutting out the keloid scar tissue with or without closure of the wound with sutures. This procedure may be followed by additional therapies such as steroid injections or radiation therapy to reduce the risk of keloid recurrence.

Radiation therapy is sometimes used after surgical excision to reduce the risk of keloid recurrence. Low-dose radiation helps prevent the regrowth of keloid scar tissue by inhibiting cell proliferation and promoting apoptosis.

Laser therapy uses focused light energy to target and break down keloid scar tissue. This treatment can help reduce redness, flatten the keloid, and improve skin texture without damaging surrounding tissues.
