Key Takeaways

  • Keloid scars are raised scar tissue caused by the body’s excessive production of collagen in response to skin injuries.
  • Treatment plans can involve corticosteroid injections, laser therapy, and surgical removal tailored to an individual’s needs.
  • Prevention strategies include proper wound care and avoiding sun exposure for reducing risk of developing keloids.

What Are Keloid Scars?

Keloid scars are a unique type of raised scar tissue that forms after skin injuries and may continue to grow due to abnormal healing processes. Susceptibility to keloid scars can be influenced by genetic factors, making some individuals more prone to their development, including small keloids. Any skin injury, such as:

  • body piercings
  • surgery
  • trauma
  • burns
  • insect bites
  • acne

can lead to the formation of keloid scars. These scars can have a significant impact on a person’s self-esteem and quality of life, making it crucial to seek treatment and develop prevention strategies.

We’ll delve into the symptoms and causes of keloid scars next, including the diagnostic procedures involved. We’ll then explore comprehensive treatment approaches, including corticosteroid injections, laser therapy, and surgical removal. Finally, we’ll discuss prevention strategies and home remedies to help manage and potentially avoid keloid scar formation.

Symptoms and Causes

Keloid scars are characterised by their raised, thick appearance, which can sometimes be accompanied by itching or pain. These scars form due to various skin injuries, including:

  • acne scars
  • burns
  • surgical incisions
  • piercings

They are the result of the body’s excessive production of collagen during the healing process. This overproduction of collagen causes an overgrowth of scar tissue, leading to the presence of keloid scars.

The potential causes of keloid scars include skin injuries, infections, or piercings. In some cases, the body’s attempt to repair broken blood vessels and damaged tissue can lead to the formation of these troublesome scars.

Certain skin types, such as those with darker skin, and ethnic groups, such as individuals of African, Asian, or Latin-American descent, are more likely to develop keloid scars compared to those people with lighter skin tones.

Diagnosis Process

Diagnosing keloid scars typically involves a visual examination by a dermatologist, who will observe signs such as:

  • Increased skin thickness
  • Discoloration in shades of red or purple
  • Itching or tenderness
  • Irritation

In some cases, a skin biopsy may be necessary to confirm the diagnosis and rule out skin cancer.

Keloid scars are often observed on the:

  • Chest
  • Shoulders
  • Earlobes
  • Cheeks

If a keloid scar is suspected, consulting a dermatologist for an accurate evaluation and personal treatment advice is highly recommended.

Comprehensive Treatment Approaches for Keloid Scars

A comprehensive treatment plan for keloid scars may involve a combination of different approaches, such as corticosteroid injections, laser therapy, and surgical removal. Your dermatologist will carefully assess your condition and devise a tailored treatment plan that best suits your individual needs. The goal of treatment is to reduce the size and appearance of the keloid scar while minimising the risk of recurrence.

In the next few sections, we’ll delve into each treatment option, outlining their potential benefits and drawbacks. Keep in mind that every individual’s experience with keloid scars is unique, and the most effective treatment plan will depend on factors such as age, type of keloid, and personal preferences.

Corticosteroid Injections

Corticosteroid injections are a widely used treatment for keloid scars, involving the injection of a corticosteroid solution, such as Triamcinolone Acetonide, directly into the keloid. These injections help break down scar tissue and reduce inflammation, resulting in a decrease in the size and appearance of the keloid. Corticosteroid injections can be employed alone or in conjunction with other therapies, such as surgical excision.

Generally, two or three corticosteroid injections are administered at intervals of one month for keloid scar treatment. This treatment approach is effective in diminishing the size and inflammation of keloid scars, helping to alleviate discomfort and improve the overall appearance of the skin.

Laser Therapy

Laser therapy for keloid scars involves targeting the scar tissue with a powerful beam of light. This treatment can assist in:

  • Flattening the scar
  • Reducing itchiness
  • Fading the scar
  • Improving movement in the affected area

Various types of laser therapies, such as pulsed dye laser therapy or fractional laser, may be employed for laser treatment, sometimes in conjunction with steroid injections.

The efficacy of laser therapy in augmenting the appearance and texture of keloid scars has shown potential, with improvement rates ranging from 57 to 83 percent in some studies. However, further research is necessary to ascertain the effectiveness of various types of lasers for keloid scar treatment.

Typically, the recovery time after laser therapy ranges from 3 to 10 days for the skin to heal, with several months needed to observe the complete outcome of the treatment.

Surgical Removal

Surgical removal of keloid scars may be necessary in some cases. The surgical procedure involves the excision of the keloid under local anesthesia, followed by suturing the wound shut. While surgical removal is a viable treatment option for keloid scars, there is a potential for recurrence or worsening of the scar after surgery.

To minimise the risk of recurrence, corticosteroid injections or radiation therapy may be used after surgery, reducing the recurrence rate to less than 50 percent. The estimated recovery time following keloid scar surgery is typically six weeks, although this may vary depending on individual healing times and other considerations.

Hypertrophic Scars vs. Keloid Scars

A comparison of a hypertrophic scar and a keloid scar

Hypertrophic scars, like keloid scars, are raised scars that form after a serious injury or surgical procedure. However, they differ from keloid scars in several ways. Hypertrophic scars are usually confined to the area of the original injury and may reduce in size over time, while keloids tend to spread beyond the boundaries of the initial trauma and remain unchanged. Histologically, hypertrophic scars typically exhibit a wavy and regular pattern of collagen, whereas keloids show no clear pattern of collagen.

Both hypertrophic and keloid scars share similar triggers and causes, such as skin injuries, infections, and piercings. However, the treatment approaches for these two types of scars may differ, with hypertrophic scars typically being treated with corticosteroid injections and surgery with tension-releasing techniques, while keloid scars may require a more varied range of treatments, including silicone sheeting and other therapies.

Prevention Strategies for Keloid Scars

Controlling keloids and maintaining healthy surrounding skin hinges on effective prevention of these scars. In the following subsections, we’ll discuss strategies to reduce the risk of developing keloids through proper wound care and avoiding sun exposure.

To prevent keloid scars, it’s essential to grasp and implement these measures, which can help control your skin’s healing process and reduce the possibility of forming keloid scars.

Reducing the Risk of Developing Keloids

Reducing the risk of developing keloids involves proper wound care and avoiding unnecessary skin trauma. Skin trauma plays a significant role in the development of keloid scars, as it can cause abnormal wound healing, leading to the formation of keloid scars that are larger than the original injury. Adhering to correct wound care techniques and avoiding unnecessary skin trauma like tattoos or body piercings is vital in reducing the chances of keloid scar formation.

To prevent the formation of keloid scars, follow these steps:

  1. Wash the injured skin immediately with soap and water.
  2. Bandage the area with hydrogel wound dressing or sterile bandages.
  3. Apply a thin layer of petroleum jelly and a nonstick bandage to cover a new wound.
  4. Use silicone gel bandages after the wound is healed to apply even pressure and prevent keloid growth.

It’s important to note that these strategies are based on general recommendations, and it’s advisable to consult with a healthcare professional for personalised advice.

Sun Exposure and Keloid Scars

Sun exposure can worsen keloid scars, potentially making them darker and more visible. Shielding your skin from sun exposure is particularly important when dealing with keloid scars. Here are some ways to protect your skin from the sun:

  • Use a broad-spectrum sunscreen with a high SPF
  • Wear protective clothing, such as long sleeves and hats
  • Seek shade whenever possible
  • Avoid peak sun hours, typically between 10 am and 4 pm

By taking these precautions, you can help shield your skin from the sun’s harmful rays and reduce the risk of keloid scar development.

Beyond sun protection, awareness of the potential influence of vitamin D on keloid scars is also significant. Research suggests that vitamin D deficiency may be a contributing factor to the development of keloid scars, and intralesional vitamin D treatment has shown promise in treating keloid scars. Be mindful of your vitamin D levels and consult with a healthcare professional for personalised advice on maintaining healthy skin.
