Keloids form when the skin’s healing process goes into overdrive. After an injury—such as a cut, burn, piercing, surgery, or even acne—the body produces excessive collagen, leading to the development of a keloid. Certain individuals are more prone to keloids due to genetic factors. People with darker skin tones, particularly those of African, Asian, or Latin descent, are more likely to develop keloid scars. Other triggers include infections at wound sites, hormonal changes, or even minor injuries like insect bites.

Keloids typically begin as raised scars at the site of a skin injury. Over time, they become larger and extend beyond the original wound area. The surface of the keloid may feel firm or rubbery and often has a shiny appearance. Some individuals may experience itchiness, tenderness, or discomfort in the area. Keloids can vary in size, from small, localized scars to larger, more prominent areas.

Preventing keloid scars can be challenging, but certain measures can reduce the risk. If you are prone to keloids, avoid unnecessary skin trauma such as piercings or tattoos. Protecting healing wounds from infection and keeping them clean can also help prevent keloid formation. In some cases, pressure dressings or silicone sheets are used to reduce the likelihood of developing keloids after surgery or injury.
