A hypertrophic scar is a type of raised and thickened scar that forms at the site of a healed injury or wound. Unlike keloid scars, which extend beyond the boundaries of the original wound, hypertrophic scars remain within the confines of the injury site. These scars result from an overproduction of collagen during the healing process, leading to a raised and sometimes red or pink appearance. Hypertrophic scars can be itchy, uncomfortable, and aesthetically bothersome. They commonly occur after trauma, surgery, or burns, and their development may be influenced by factors such as genetic predisposition and the location and type of the wound.
