Keloids
What is a keloid?
A keloid is a type of scar characterized by an overproduction of collagen, resulting to an irregularly shaped, firm, smooth, and usually pink or purple lesion. It grows at the site of a healed injury such as scratches, burns, acne, piercings, and wounds. Any part of the body can develop a keloid.
Keloids should not be confused with hypertrophic scars. Both are raised scars, but the main difference between the two is that keloids tend to extend beyond the boundaries of the original site of the wound.
What causes keloids?
Doctors do not exactly know why some people develop keloids, while others don’t. Some evidence suggests that a person’s genetic disposition and tendency to develop keloid scars may contribute to the development of this type of scar. [1]
Who are more prone to developing keloids?
People of all ages can develop keloids, however, they are less likely to occur in children. Although Dark skinned people are more susceptible to developing keloids, they can occur in people of all skin types. They also affect both sexes equally, but it has been reported that more women develop this type of scar than men, possibly due to piercings and cosmetic surgeries.
Prevention and treatment for keloids
The best way to prevent keloids is to avoid piercings, elective surgeries, and skin injuries, especially when one has had a keloid.
Keloids are not a health hazard, but they are unsightly and people often seek treatment due to aesthetic reasons. Treatments for keloids include cortisone injections, surgery, laser, silicone sheets, and cryotherapy.
