Keloids, those raised, often itchy, and sometimes painful scars that can form after skin injuries, are a source of concern for many individuals. Fortunately, there are steps you can take to prevent keloids from developing in the first place and effective keloid treatments are available if they do occur. In this comprehensive guide, we'll explore the various ways to prevent keloids and discuss advanced treatment options in Singapore. If you're looking for expert advice and treatment, consider consulting a specialized doctor at 1Aesthetics.

Can You Prevent Keloids?

Preventing keloids entirely may not always be possible, as some individuals are more predisposed to keloid formation due to genetic factors. Furthermore, even normal individuals who have no predisposition to keloid formation can develop keloids in certain locations or due to other factors such as prolonged healing, infection, or severe wounds. However, there are several strategies you can employ to reduce the risk of keloid formation or minimize their appearance.

  1. Early Good Wound Care: Proper wound care is crucial in preventing keloids. Cleanse wounds gently with a mild disinfectant, then keep them covered with a sterile bandage to protect against infection. Hydrocolloid dressings may help improve wound healing.
  2. Treat Infections Promptly and Aggressively: Infections can stimulate inflammation that exacerbates keloid formation. If you suspect an infection in a wound, seek immediate medical attention for proper treatment and antibiotics.
  3. Use Growth Factors: By speeding up and improving wound healing, growth factors may reduce the duration and intensity of the inflammatory response, reducing the tendency to develop keloid scarring.
  4. Use Silicone Gel or Sheets: Silicone gel or sheets can be effective in preventing keloid formation or minimizing their appearance. These products help maintain a moist environment for the wound and can flatten keloids over time.
  5. Topical Medications: Topical treatments, such as corticosteroid creams or other keloid removal creams, can be applied to the wound site to reduce inflammation and the chance of keloid formation.
  6. Application of Pressure: Applying pressure to the wound using pressure dressings or silicone sheets can help flatten the keloid. Pressure can reduce blood flow to the keloid, which may slow its growth.
  7. Avoid Unnecessary Trauma or Surgery: Whenever possible, minimize trauma to your skin. Avoid elective cosmetic surgeries in areas prone to keloids unless necessary, and discuss the risks with your surgeon.
  8. Prophylactic Injectables: Some medical professionals offer prophylactic treatments with injectables like steroids or neurotoxins before surgery to reduce the risk of keloid formation. These treatments can help modulate the body's healing response. New systemic injectables such as monoclonal antibodies have also been found to be helpful in reducing the risk of keloid formation.
  9. Consult a Doctor Specialized in Keloid Scar Treatments: For individuals at high risk of keloid formation, consulting a doctor who specializes in keloid scar treatments can be invaluable. They can assess your risk factors and recommend early preventive measures tailored to your unique situation.

Early Treatment: A Key to Success

Despite preventive measures, keloids can still develop. However, the good news is that early intervention often yields better results. If you notice the signs of keloid formation, such as raised, red, or itchy scars, don't delay seeking professional help. Timely treatment can make a significant difference in minimizing the appearance of keloids.

Advanced Keloid Removal Treatments in Singapore

In Singapore, we are lucky to have access to advanced keloid removal treatments that can effectively reduce or eliminate keloids. These treatments are often administered by specialized doctors who have a deep understanding of keloid management. Let's explore some of these advanced options:

  1. Cryotherapy: Cryotherapy involves freezing the keloid with liquid nitrogen, causing it to shrink. This treatment is less commonly employed nowadays.
  2. Corticosteroid And Other Injections: Corticosteroid injections are a common treatment for keloids. A series of injections into the keloid can help reduce inflammation, flatten the scar, and alleviate symptoms. Other injectable medications such as neurotoxins can also be used alone or in combination with steroids.
  3. Laser Therapy: Laser treatments, such as ablative or vascular lasers, can target keloids with precision. They work by reducing the blood supply to or breaking down excess collagen in the scar tissue, leading to a smoother appearance.
  4. Surgical Excision: Surgical removal of keloids is an option for larger or more complex keloids particularly those with a mature keloid core. The keloid is surgically excised, and the wound is carefully closed. Post-surgery, additional treatments are necessary to prevent recurrence.
  5. Pressure Garments: Pressure garments, designed to apply consistent pressure to the keloid, can help flatten and soften the scar. These garments are typically worn for several months.
  6. Radiation Therapy: In some cases, radiation therapy may be recommended after surgical excision to prevent keloid recurrence. It's essential to discuss the potential risks and benefits with your doctor.
