A keloid scar is a thick, elevated scar that remains on the skin after a wound has healed. It typically develops a few weeks to years following skin damage or injury, such as acne, burns, or cuts. One’s physical health will not be harmed by a keloid scar, but it may cause mental distress. The key is early detection and treatment.
Although it can appear anywhere there is skin damage, it typically manifests on the chest, shoulders, cheeks, or earlobes. If one is prone to getting keloids, there may be multiple sites where they form. A keloid scar typically enlarges over the course of months or years, surpassing the size of the initial wound.
Keloid scar could hurt or itch while it is growing. If it is on or close to a joint, it may cause discomfort or make movement in the joint problematic. Treatment may include flattening or removal of the keloid scar. However, it can recur or last for years even after treatment.
A keloid scar can develop anywhere from a few months to several years after the initial injury or trauma occurs. Signs and symptoms of a keloid scar include:

Researchers believed that various skin injuries, such as insect bites, acne, injections, body piercings, burns, hair removal, and even minor scratches and bumps, can potentially trigger keloid growth. Most concur that it is probably a dysfunction in the wound-healing process. It can also occur due to excessive collagen production. Collagen is the protein present throughout the body and essential for wound healing.
Several factors may contribute to one’s risk of developing keloid scars, such as:
