 In dermatology, an abrasion, is superficial damage to the skin, generally not deeper than the epidermis. It is more superficial than an excoriation, although it can give mild bleeding. Mild abrasions, also known as 'grazes' do not scar, but deep abrasions may lead to the development of scarring tissue. An more serious abrasion injury that removes all of the layers of skin is more commonly called an avulsion injury. Most commonly, abrasion injuries occur when exposed skin comes into moving contact with a rough surface causing trauma to the upper layers of the epidermis. Such injuries, where caused by abrasive contact with textiles or carpet, are sometimes referred to as 'rug burn' or 'carpet burn'. See also
