Why Do Keloids Form?
Keloids can develop as a result of trauma to the skin. Rarely, people will develop a keloid without previous injury to the body. These keloids are referred to as “spontaneous” keloids. When a keloid-prone person sustains an injury to the skin, their body goes into overdrive in an attempt to heal the injury. It will begin to overproduce collagen, the building block of scar tissue, long after the initial wound is closed.
Most commonly, a keloid will form at the site of trauma to the skin. Some injuries where keloids tend to occur include:
- Scrapes Cuts
- Body piercing, especially the ears
- Vaccination sites
Who Is at Risk for Developing Keloids?
While anyone can develop a keloid, some people are more prone to them than others. Genetics appears to be a factor in the development of keloids. There are certain groups who are more likely to develop keloids, including Asians, African Americans, and Hispanic Americans. Keloids frequently occur in young people between the ages of 10 and 30. Pregnant women tend to have a higher risk of developing keloids.
For those who have a genetic predisposition to keloids, there are some precautions you can take to prevent one from forming on your skin. Avoid body piercings, tattoos, and any unnecessary surgeries. When an injury to the skin does occur, take care of the wound right away and see your dermatologist. If surgery is required, be sure to inform your doctor. There are measures that a surgeon can take to reduce the risk of developing a keloid.
Keloid Treatment Options
Keloids are not dangerous or cancerous; however, many people obtain keloid treatment when the keloids are itchy, tender or uncomfortable. Others choose to treat keloids for cosmetic reasons or to improve mobility if the keloid develops on a joint.
There is no one-size-fits-all treatment for keloids. In fact, it is common for a treated keloid to return over time. Your dermatologist may suggest a combination of treatment options to obtain your optimal results. However, it is important to understand that treatment may not completely remove the keloid or give you the results that you desire. A dermatologist may recommend available treatments including:
- Silicone Pads: Moist sheets of silicone gel are placed over the keloid to reduce the size of the scar. This is a safe and more conservative treatment option.
- Pressure Dressings: Constant compression is applied to the keloid to reduce it in size. This treatment may require compression for six months to one year.
- Topical Treatments: Applied directly to the keloid, medications can include retinoids, steroids and anti-inflammatory ointments.
- Cryosurgery: Using liquid nitrogen to freeze the keloid, treatment must be repeated monthly and can result in lightening of the skin.
- Injections: Corticosteroid injections, repeated every four to six weeks, can soften and reduce the size of a keloid.
- Laser Treatments: Most commonly used in combination with other treatments, laser treatments can flatten and lighten the appearance of the keloid.
- Surgical Procedures: The physical removal of a keloid, surgery is often paired with other treatment options to reduce the risk of the keloid returning. Most keloids do reappear after surgical treatment.
Although a keloid may not pose any serious health risks, it is still important to contact a dermatologist to learn more about proper care, prevention and keloid treatment. There are a range of treatment options available, from conservative dressings and compression to more advanced laser treatments and surgery. Your dermatologist will make sure you fully understand your options and provide recommendations that are appropriate for your skin.
