Treatment Overview

For many people, keloids are more than just a cosmetic concern; they can be a source of physical discomfort and emotional distress. Unlike normal scars that fade over time, keloids are aggressive overgrowths of scar tissue that extend beyond the boundaries of the original wound. They can be tender, itchy, and painful to the touch, sometimes restricting movement if they form over a joint. Living with keloids often means managing self-consciousness about appearance while dealing with the frustration of their recurrence.

Treatment is essential to reduce the physical symptoms of itching and pain, as well as to flatten and soften the raised tissue. Because keloids are notoriously stubborn and prone to growing back even after removal, a proactive and often multimodal approach is required. Treatment plans are highly individualized, depending on the size, location, and age of the keloid, as well as the patient’s skin type and history of scarring (American Academy of Dermatology, 2024).

Overview of treatment options for Keloids

The primary goals of treating keloids are to flatten the raised tissue, reduce redness, and alleviate itching or tenderness. While surgical removal is an option, it is rarely performed alone because clinical experience suggests it carries a high risk of stimulating the keloid to grow back even larger. Therefore, medication-based treatments are almost always the first line of defense or are used in conjunction with procedures to prevent recurrence.

Medical treatment typically involves intralesional therapy, where medication is injected directly into the scar tissue. Topical creams and gels may be used for smaller, newer keloids or as maintenance therapy. The approach is generally gradual, requiring multiple visits to see significant improvement.

Medications used for Keloids

Corticosteroid injections are the gold standard for treating keloids. The most commonly used drug in this class is triamcinolone acetonide. These injections are typically administered directly into the scar every four to six weeks. Patients can usually expect the keloid to become softer and less itchy within a few days of the first injection, though significant flattening often takes several sessions. Studies show that 50% to 100% of patients see improvement with corticosteroid injections alone.

When steroids alone are insufficient, doctors may introduce antineoplastic agents, drugs originally developed for chemotherapy but used here in low doses for their ability to stop cell growth. 5-Fluorouracil (5-FU) is frequently mixed with corticosteroids to enhance results and reduce side effects. Another option is bleomycin, which is injected into the scar to induce regression.

For topical management, prescription creams like imiquimod may be used, particularly after surgical removal, to stimulate the immune system and prevent regrowth. Silicone gel sheets, while not pharmaceutical in the traditional sense, are also a standard, evidence-based topical option often recommended alongside medications to hydrate the scar and suppress growth (Mayo Clinic, 2022).

How these medications work

Keloids occur when the body’s healing process goes into overdrive, producing excess collagen. Corticosteroids work by suppressing inflammation and constricting the blood vessels that feed the scar tissue. More importantly, they inhibit the activity of fibroblasts, the cells responsible for producing collagen. By slowing down these cells, the drug prevents new scar tissue from forming and encourages the breakdown of existing collagen.

Antineoplastic agents like 5-FU and bleomycin work by interfering with the DNA synthesis of the rapidly dividing cells within the keloid. Essentially, they act as a “brake” on the cellular machinery that is creating the excess tissue. Imiquimod works differently by modifying the local immune response, triggering the production of interferon, a protein that helps break down collagen (National Institutes of Health, 2023).

Side effects and safety considerations

While effective, intralesional injections carry local side effects. Corticosteroids may cause permanent cosmetic changes like skin atrophy (thinning), a depression where the keloid was, hypopigmentation (lightening), or spider veins (telangiectasia) at the injection site.

5-FU injections can be painful, cause temporary purple discoloration or skin ulceration, and are strictly contraindicated during pregnancy due to interference with cell replication. Patients should seek medical care for signs of infection at the injection site (warmth, pus, spreading redness).

Since everyone’s experience with the condition and its treatments can vary, working closely with a qualified healthcare provider helps ensure safe and effective care.
