What Is a Keloid Scar, and Can it Be Treated?

Nov 9 • 3 minute read

Scars are a natural part of the body’s healing process, but in some cases, they can develop into raised, thickened growths known as keloid scars. These scars can be not only physically uncomfortable but also emotionally distressing for many individuals. In this blog, we’ll delve into what keloid scars are, what causes them, and explore treatment options available to help alleviate their appearance and discomfort.

Understanding Keloid Scars

A keloid scar is an overgrowth of scar tissue that extends beyond the boundaries of the original wound. Unlike typical scars, which gradually fade and become flatter over time, keloids continue to grow, often becoming raised, firm, and discolored. They can vary in size, ranging from a few centimeters to several inches in diameter. Keloid scars most commonly occur on the chest, back, shoulders, and earlobes, but they can develop anywhere on the body.

Causes of Keloid Scars

The exact cause of keloid formation is not fully understood. However, many experts believe they are caused by a dysfunction of the healing process when too much collagen is produced. Any skin wound can form into a keloid scar, but several factors may contribute to their development. These include:

  • Genetics: Some individuals may have a genetic predisposition to keloid formation. If a family member has experienced keloid scarring, there may be an increased likelihood of developing them as well.
  • Wound Type and Location: Certain types of wounds, such as burns, severe acne, surgical incisions, or piercings, are more prone to keloid formation. Additionally, areas with high tension, like the chest or shoulders, are more susceptible.
  • Ethnicity: Keloid scars are more prevalent in individuals with darker skin tones, particularly those of African, Asian, or Hispanic descent.
  • Hormonal Influences: Changes in hormone levels, such as those occurring during pregnancy or adolescence, may contribute to keloid formation.

Treatment Options for Keloid Scars

While keloid scars can be challenging to treat, several options are available to help manage their appearance and alleviate discomfort. It’s common for people to undergo multiple types of treatment to get the best results, depending on the severity and placement of the scar. Some treatments include:

  • Steroid Injections: Corticosteroid injections are a common treatment for keloid scars. They work by reducing inflammation and suppressing the overproduction of collagen, which is responsible for the raised appearance of keloids.
  • Surgical Excision: Surgical removal of a keloid scar is an option, but it’s important to note that keloids have a tendency to recur after excision. To minimize recurrence, surgery is often combined with other treatments, such as radiation therapy, steroid injections, and pressure garments.
  • Radiation Therapy: Radiation therapy following surgical excision can help reduce the likelihood of keloid recurrence. It works by inhibiting the growth of scar tissue.
  • Silicone Sheets or Gels: Applying silicone sheets or gels to keloid scars can help flatten and soften the tissue. This treatment is most effective when used consistently over an extended period.
  • Laser Therapy: Certain types of lasers, such as pulsed dye lasers, can be used to reduce the redness and thickness of keloid scars. Laser therapy works by targeting blood vessels and collagen in the scar tissue. This treatment is often used in conjunction with pressure garments or injections.
  • Cryotherapy: Cryotherapy involves freezing the keloid with liquid nitrogen. While it can be effective, multiple sessions may be required. However, cryotherapy may not be recommended for those with darkly pigmented skin, as it can permanently lighten the skin where the scar is.

Explore Your Cosmetic Options

Keloid scars can be physically and emotionally distressing, but there are treatment options available to help manage their appearance and alleviate discomfort. It’s important to consult with a qualified dermatologist or plastic surgeon to determine the most appropriate treatment plan based on the individual characteristics of the keloid. While complete removal of a keloid scar may not always be possible, the right treatment approach can lead to significant improvement in its appearance and overall quality of life for the affected individual.
