Tissue Damage and Skin Repair Many superficial injuries of the epidermis will repair themselves without scarring. However, once the dermis is injured, scarring may occur as a result of tissue repair and wound contracture processes. As skin ages and/or disease affects the skin, it has less elastic and regenerative properties due to the loss of collagen, elastin and dermal blood vessels. The loss of collagen increases the vulnerability of capillaries, leading them to collapse. This not only makes the skin less resistant to damage, but decreases its ability to repair.
