A keloid is a raised scar that develops after skin injury, often causing cosmetic concern or discomfort. Many individuals explore at-home solutions, but professional medical advice is crucial. Self-removal is not recommended, as it can lead to complications and is generally ineffective. This article explains what keloids are, why home removal methods are unsafe, outlines effective medical treatments, and provides prevention strategies.
What Are Keloids?
Keloids are firm, raised scars that result from excessive scar tissue growth. Unlike typical scars, keloids extend beyond the original injury, sometimes growing significantly larger. They commonly appear on the chest, shoulders, earlobes, and upper back, often feeling lumpy or rubbery. These scars can also be itchy, painful, or tender and do not typically fade.
Keloid formation results from fibroblasts producing an overabundance of collagen during wound healing. Any skin injury can trigger a keloid, including surgical cuts, acne, burns, chickenpox, piercings, or minor scratches. Certain individuals are more susceptible, particularly those with darker skin tones (African, Asian, Hispanic descent). A genetic predisposition also plays a role, as keloids often run in families and are more common in individuals aged 10 to 30.
Why Home Removal is Not Safe
Attempting to remove keloids at home is strongly discouraged due to the high risk of severe complications and potential worsening. Without a sterile environment and medical expertise, self-treatment can introduce new problems or exacerbate existing ones. Keloids are particularly resistant to casual interventions.
One significant risk is increased scar tissue formation. Irritating a keloid through unproven methods can trigger the body’s overactive healing response, causing the keloid to grow larger or leading to new, more extensive scars.
Infection poses another serious threat. Poor hygiene or non-sterile tools used at home can easily introduce bacteria, leading to painful infections that prolong healing and may require antibiotics. Cutting, abrading, or forcefully removing a keloid at home can cause significant pain and bleeding, creating an open wound vulnerable to further complications. Unprofessional attempts can also lead to disfigurement.
Many popular “home remedies” like apple cider vinegar, tea tree oil, garlic, or lemon juice lack scientific evidence for keloid removal. These substances can cause severe skin irritation, chemical burns, allergic reactions, or hyperpigmentation on sensitive keloid tissue. Such adverse reactions not only fail to reduce the keloid but can also inflame the area, potentially causing the scar to thicken, spread, or become more discolored.
Effective Medical Treatments for Keloids
Professional medical treatments for keloids aim to reduce their size, alleviate symptoms, and improve appearance. Dermatologists or plastic surgeons perform these procedures.
- Corticosteroid injections: A frequent first-line treatment. A steroid solution is injected directly into the keloid to flatten and soften scar tissue. Monthly injections are often required.
- Cryotherapy: Freezing the keloid with liquid nitrogen reduces its size and firmness. This destroys keloid tissue from the inside out, but can cause temporary blistering or pigmentation changes.
- Laser treatment: (e.g., pulsed-dye or Nd:YAG lasers) can flatten keloids and reduce redness. Often used with other treatments, it typically requires multiple sessions for optimal results.
- Surgical excision: Can remove a keloid but carries a high recurrence risk (45-100% if performed alone). Surgery is almost always combined with other therapies to minimize regrowth.
- Silicone sheets or gels: Non-invasive options that apply pressure to flatten the scar and prevent recurrence. Consistent wear for several months is needed.
- Pressure garments or earrings: Used to inhibit keloid regrowth.
- Radiation therapy: In stubborn cases, may be used immediately following surgical removal. Low-dose radiation targets scar tissue to prevent its return.
Preventing Keloid Formation and Recurrence
For individuals prone to keloids, prevention involves proactive measures and careful skin injury management. While complete prevention isn’t always possible due to genetic predisposition, certain steps can reduce the risk of recurrence.
Proper wound care is fundamental. When skin is injured, gently clean the area with mild soap and water, keeping it moist with petroleum jelly and a bandage. This promotes healthy healing until the wound fully heals.
Avoid unnecessary skin trauma like elective cosmetic surgeries, piercings, or tattoos. These intentionally injure the skin and can trigger keloid development. Even minor injuries like ingrown hairs or scratches can initiate keloid growth.
If surgery is necessary, discuss keloid tendency with the surgeon for techniques that reduce scarring and preventative post-operative care. Early intervention is important; if a scar thickens or shows signs of keloid formation, seek medical advice promptly for earlier treatment and improved outcomes. Following professional post-treatment instructions (e.g., consistent silicone product or pressure therapy use) is crucial in preventing recurrence.
