This observation is partly attributed to the following facts: young individuals are more prone to trauma their skin generally possesses more elastic fibers, resulting in greater tension and the rate of collagen synthesis is greater in younger individuals 4). The elderly rarely develop these lesions 3). The majority of individuals who develop hypertrophic scars and keloids are young, with ages ranging from 10 to 30 years old. Hypertrophic scars are characterized by proliferation of the dermal tissue, with excessive deposition of fibroblast-derived extracellular matrix proteins and especially collagen, over long periods and by persistent inflammation and fibrosis 2). If there is a lot of tension on a healing wound, the healing area is rather thicker and elevated than usual. Over several months, a scar usually becomes flat and pale. As wounds heal, scar tissue forms, which at first is often red and somewhat prominent. Scar formation is a consequence of the wound healing process that occurs when body tissues are damaged by a physical injury. Hypertrophic scars are defined as visible and elevated scars that do not spread into surrounding tissues and that often regress spontaneously 1).
