Why Do Scars Form? | Biodermis.com
The dermis and epidermis layers of the skin play pertinent roles in scar formation and work to facilitate a natural, biologic process of wound repair. When a person sustains a wound that penetrates the middle layer of the skin—the dermis—the skin repair response begins. Damage to the dermis layer signals fibroblast skin cells to synthesize massive amounts of collagen. The collagen is then sent to the wound site, promoting the growth factor, and rebuilding new skin tissue. The epidermis flaunts the new tissue as a scar, which can appear discolored and raised.
