Keloids are a type of abnormal wound healing that results in raised, thickened scar tissue extending beyond the original injury. Individuals who develop keloids, especially in highly visible areas such as the face, neck, or chest, can cause emotional distress due to their appearance, alongside physical discomforts like itching, pain, and restricted movement.

Keloids present a unique challenge in dermatology due to their unpredictable nature and the high likelihood of recurrence after treatment. While surgical excision used to be a common option, the high rates of recurrence—sometimes up to 70%—have prompted both medical professionals and patients to seek less invasive alternatives. In recent years, there has been a growing focus on non-invasive treatments that aim to minimize the risks, reduce recurrence rates, and offer effective outcomes.

In Bangalore, a city known for its advanced healthcare infrastructure and focus on medical research, there are various options for non-invasive keloid treatments. These treatments range from steroid injections and cryotherapy to advanced laser therapy and emerging technologies like radiofrequency treatment. This article will explore the available non-invasive keloid treatment options in Bangalore and assess their outcomes.

Understanding Keloids

Before delving into treatments, it's important to understand what keloids are and why they occur. When the skin is injured, the body sends signals to heal the wound through the formation of new tissue. In some individuals, the healing process goes awry, and the body continues to produce collagen beyond what is needed for healing, resulting in the formation of a keloid scar.

Keloids can form anywhere on the body, though they are most common on the chest, shoulders, upper back, and earlobes. They may continue to grow for months or even years after the initial injury. Keloids are often a genetic predisposition, meaning certain individuals are more prone to developing them, particularly those with darker skin tones, including individuals of African, Hispanic, and South Asian descent.

Given the city's diverse population and the prevalence of keloids among South Asians, Bangalore has become a hub for treating keloid scars. Let's examine the available non-invasive treatment options.

Steroid Injections

One of the most commonly used non-invasive treatments for keloids is intralesional corticosteroid injections. This method involves injecting corticosteroids directly into the keloid scar to reduce inflammation and slow the production of collagen.

How It Works:

Steroid injections help by softening the scar tissue and flattening the keloid over time. The anti-inflammatory properties of corticosteroids suppress collagen production, which is the primary culprit in keloid formation.

Procedure:

  • The doctor injects a small amount of the steroid (often triamcinolone acetonide) directly into the keloid.
  • The procedure is typically repeated every 4 to 6 weeks, depending on the size and response of the keloid.

Outcomes:

  • Effectiveness: Steroid injections have been shown to reduce the size and appearance of keloids by 50-80% in many cases. However, they often need to be combined with other therapies like cryotherapy or silicone sheets for more comprehensive results.
  • Recurrence Rate: Despite the treatment's efficacy, recurrence can still occur, with some studies reporting recurrence rates of up to 50% if used as a standalone treatment.

Steroid injections remain a first-line treatment due to their relative simplicity and effectiveness, but patients often require additional treatments for more significant improvements.

Cryotherapy

Cryotherapy, or cryosurgery, is another non-invasive treatment option widely available in Bangalore. This technique involves freezing the keloid tissue with liquid nitrogen, causing it to die and eventually fall off.

How It Works:

Cryotherapy works by destroying the abnormal scar tissue through freezing, which damages the cells and reduces collagen production. This process can effectively flatten the keloid over time.

Procedure:

  • A dermatologist applies liquid nitrogen directly to the keloid, freezing the tissue.
  • The area will blister, and the frozen tissue will fall off after several sessions.
  • Cryotherapy is often combined with other treatments like steroid injections or pressure therapy for more comprehensive results.

Outcomes:

  • Effectiveness: Studies show cryotherapy can reduce the size of keloids by up to 70%. However, it is more effective for smaller keloids and those that are relatively new.
  • Recurrence Rate: Like steroid injections, cryotherapy has a moderate risk of recurrence, with rates ranging from 20% to 50%, depending on the size and location of the keloid.

Cryotherapy is especially effective when combined with other treatments, making it a valuable option in the multi-faceted approach to non-invasive keloid treatment in Bangalore.

Laser Therapy

Laser therapy has emerged as a popular non-invasive option for treating keloids, particularly in cities like Bangalore, where advanced medical technology is readily accessible. Laser therapy involves the use of highly focused light energy to treat the keloid scar tissue.

How It Works:

Lasers, such as pulsed dye lasers (PDL), target the blood vessels in the keloid tissue, reducing redness, flattening the scar, and breaking down excess collagen. The heat generated by the laser promotes the skin's natural healing process while minimizing damage to surrounding tissues.

Procedure:

  • A dermatologist uses a handheld laser device to direct the light energy at the keloid.
  • Multiple sessions (usually 3-6) are required for optimal results.
  • Depending on the laser used, the procedure can be combined with other treatments like steroid injections or silicone sheets.

Outcomes:

  • Effectiveness: Laser therapy can reduce keloid size and appearance by up to 70%, particularly in newer or smaller keloids. It also improves the color of the keloid, making it less noticeable.
  • Recurrence Rate: The recurrence rate after laser therapy is lower than with some other non-invasive treatments, with rates around 20-30%, especially when combined with other treatments like corticosteroids.

Bangalore has several specialized dermatology centers offering laser therapy, making it a convenient option for those seeking non-invasive keloid treatment.

Silicone Gel Sheets

Silicone gel sheets and silicone-based ointments are often recommended as part of a comprehensive keloid treatment plan. These products are easy to apply and available over the counter in many pharmacies in Bangalore, making them a convenient home treatment.

How It Works:

Silicone sheets work by creating a protective barrier over the keloid, which helps to hydrate the scar and reduce collagen production. This leads to a flattening of the keloid over time.

Procedure:

  • Silicone sheets or gels are applied directly to the keloid for several hours each day, typically for a period of 12 weeks or longer.
  • Silicone therapy is often combined with other treatments like steroid injections or cryotherapy.

Outcomes:

  • Effectiveness: Silicone sheets are particularly effective in preventing keloids from forming after surgery or injury. For existing keloids, they can reduce thickness and improve texture by 30-50%.
  • Recurrence Rate: The recurrence rate after silicone treatment is relatively low when used in conjunction with other therapies, with studies showing recurrence rates of 20-30%.

Silicone-based treatments are a simple, cost-effective option, often used in combination with more aggressive therapies for better results.

Radiofrequency Treatment

An emerging non-invasive treatment option in Bangalore is radiofrequency therapy. This method uses high-frequency radio waves to heat the keloid tissue, causing controlled tissue damage and stimulating collagen remodeling.

How It Works:

Radiofrequency treatment targets the abnormal tissue without damaging the surrounding skin. The heat produced by the radio waves breaks down excess collagen in the keloid, encouraging the body to resorb the tissue and promote a more normal healing process.

Procedure:

  • A specialized device delivers radiofrequency energy to the keloid.
  • The treatment is usually performed over several sessions, depending on the size and thickness of the keloid.
  • Radiofrequency treatment can be combined with other therapies like cryotherapy or steroid injections.

Outcomes:

  • Effectiveness: Early studies show promising results, with up to 60-70% improvement in keloid size and texture. Since this is a newer treatment, more long-term data is needed to assess its full efficacy.
  • Recurrence Rate: While initial studies suggest a lower recurrence rate than traditional therapies, long-term studies are required to verify these claims.

Radiofrequency therapy is gaining popularity in Bangalore due to its promising results and minimal side effects, making it an exciting new option for non-invasive keloid treatment.

Emerging Therapies and Innovations in Bangalore

Bangalore has always been at the forefront of medical innovation, and this is no different when it comes to keloid treatment. Several experimental treatments are gaining traction in the city, such as microneedling with platelet-rich plasma (PRP) and botulinum toxin injections. These therapies aim to address keloid scarring by promoting tissue remodeling and reducing inflammation. While still in the early stages, these treatments show promise for future non-invasive options.

Conclusion

Non-invasive keloid treatment options in Bangalore have expanded significantly in recent years, providing patients with a range of effective therapies with minimal risks. Whether through steroid injections, cryotherapy, laser therapy, or newer treatments like radiofrequency, patients can choose a treatment plan tailored to their needs and skin type. While recurrence remains a challenge with all keloid treatments, combining multiple therapies and adopting a long-term management plan can greatly improve outcomes.
