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.
Such injuries, where caused by abrasive contact with textiles or carpet, are sometimes referred to as 'rug burn' or 'carpet burn'.
