What Causes Keloids?

Causes of Keloids

Keloids are raised, overgrown scars that develop at the site of a wound or injury. They result from an overproduction of collagen during the healing process. While the exact cause of keloids is not fully understood, several factors contribute to their formation. Here are the main factors that can cause keloids:

  • Genetics: A significant factor in keloid formation is genetics. Some people are more prone to developing keloids due to their family history. If you have a close family member with a history of keloids, you may have a higher risk of developing them as well.
  • Skin Type: People with darker skin tones, particularly those of African, Asian, or Hispanic descent, are more susceptible to keloid formation than those with lighter skin. It is thought that increased melanin levels may play a role in the development of keloids.
  • Injury or Trauma: Keloids often develop at the site of a skin injury, such as surgical incisions, burns, acne scars, piercings, or cuts. However, not all injuries result in keloid formation, and some people are more prone to developing them than others.
  • Inflammation: Inflammation at the wound site may contribute to the development of keloids. Chronic inflammation can disrupt the normal wound healing process, leading to excessive collagen production.
  • Hormonal Factors: Some studies suggest that hormonal imbalances or changes may influence keloid formation, as they tend to be more common during puberty and pregnancy.
  • Age: Keloids are more likely to form in younger individuals, as the body’s ability to regulate collagen production tends to decrease with age.

It’s important to note that not everyone who experiences skin injuries will develop keloids. The risk varies from person to person based on the factors mentioned above. Keloids can be cosmetically bothersome and, in some cases, cause discomfort or itching. Treatment options for keloids include steroid injections, cryotherapy, laser therapy, surgical removal, or silicone gel sheets, but results can vary from person to person. If you are prone to keloids or have concerns about a particular scar, it’s best to consult a dermatologist or a healthcare professional to discuss the appropriate management and treatment options for your specific situation.
