Keloid Scars: Causes, Symptoms, and Effective Treatments

Keloid scars are a common issue that many people face, and they can be quite frustrating to deal with. As a cosmetic dentist and doctor with a deep passion for aesthetic medicine, I’ve seen my fair share of patients struggling with these raised, often discolored scars. Living in Istanbul, Turkey, I’ve had the opportunity to explore various treatments and understand the nuances of keloid scars. Today, I want to share my insights and experiences with you, hoping to provide some clarity and helpful information.

What Are Keloid Scars?

Keloid scars are a type of raised scar that occurs due to an overgrowth of collagen during the healing process. Unlike normal scars, keloids extend beyond the original wound margins and can continue to grow over time. They are often reddish or pinkish in color and can be itchy or painful. But why do some people develop keloids while others don’t?

Causes of Keloid Scars

The exact cause of keloid scars is not fully understood, but it’s believed to be related to an abnormal response to injury or inflammation. Genetics play a significant role, as keloids tend to run in families. People with darker skin tones are also more prone to developing keloids. Common triggers include:

• Surgical incisions
• Acne scars
• Burns
• Piercings and tattoos
• Vaccination sites

Is this the best approach? Let’s consider the various factors that contribute to keloid formation.

Symptoms of Keloid Scars

Keloid scars can vary in appearance and symptoms. They typically start as a raised, reddish area that grows over time. Some common symptoms include:

• Itching
• Pain or tenderness
• A smooth, shiny surface
• A rubbery or hard feel
• A size that’s disproportionate to the original wound

Maybe I should clarify that not all raised scars are keloids. Hypertrophic scars, for example, are also raised but do not extend beyond the original wound margins.

Diagnosing Keloid Scars

Diagnosing keloid scars usually involves a physical examination by a healthcare provider. In some cases, a skin biopsy may be performed to confirm the diagnosis. It’s important to rule out other conditions that can cause similar symptoms, such as hypertrophic scars or dermatofibromas.

Treatment Options for Keloid Scars

Treating keloid scars can be challenging, and there’s no one-size-fits-all solution. I’m torn between several treatment options, but ultimately, the best approach depends on the individual’s specific needs and the severity of the keloid. Here are some common treatments:

Corticosteroid Injections

Corticosteroid injections are a common first-line treatment for keloids. They help reduce inflammation and can shrink the scar. However, multiple injections may be needed, and the results can vary.

Cryotherapy

Cryotherapy involves freezing the keloid with liquid nitrogen. This can help reduce the size of the scar and alleviate symptoms. It’s often used in combination with other treatments.

Laser Therapy

Laser therapy is another option that can help reduce the appearance of keloids. Pulsed dye lasers and fractional lasers are commonly used. Laser therapy can also help improve the texture and color of the scar.

Surgical Excision

In some cases, surgical excision may be recommended. This involves cutting out the keloid. However, there’s a risk of the keloid recurring, so surgery is often combined with other treatments like corticosteroid injections or radiation therapy.

Radiation Therapy

Radiation therapy can be used to prevent the recurrence of keloids after surgery. It works by inhibiting the growth of fibroblasts, the cells responsible for scar formation.

Silicone Gel Sheeting

Silicone gel sheeting is a non-invasive treatment that can help flatten and soften keloids. It works by hydrating the scar and reducing collagen production.

Pressure Therapy

Pressure therapy involves applying constant pressure to the keloid using a bandage or garment. This can help flatten the scar and reduce its size.

Topical Treatments

Topical treatments like imiquimod cream can be used to treat keloids. Imiquimod works by modulating the immune response and reducing inflammation.

Combination Therapy

Often, a combination of treatments is used to achieve the best results. For example, surgery followed by corticosteroid injections and radiation therapy can be effective in managing keloids.

It’s important to note that treating keloids can be a long process, and results may vary. Patience and persistence are key.

Preventing Keloid Scars

While it’s not always possible to prevent keloids, there are some steps you can take to reduce your risk:

• Avoid unnecessary surgeries or procedures that can cause scarring.
• Treat any wounds or injuries promptly to minimize scarring.
• Avoid piercings and tattoos, especially if you have a family history of keloids.
• Use pressure garments or silicone gel sheeting after surgery or injury to help prevent keloid formation.

When to See a Doctor

If you suspect you have a keloid scar, it’s important to see a healthcare provider for an accurate diagnosis and treatment plan. Early intervention can help prevent the keloid from growing larger and causing more discomfort.

Conclusion

Keloid scars can be a frustrating and challenging condition to deal with. However, with the right treatment and a bit of patience, it’s possible to manage and even reduce their appearance. If you’re struggling with keloids, don’t hesitate to reach out to a healthcare provider for help.

I challenge you to take the first step towards understanding and treating your keloid scars. It’s a journey, but with the right guidance and support, you can achieve the results you desire.
