Skin abrasions

 Abrasions are due to scraping of the surface layer of the skin, leaving the basement membrane intact and therefore maintaining the capacity to heal by itself in more than 50% of cases. When the dermis is affected over most of the abrasion, it will result in a scar. Complete epithelialisation of the abrasion, usually achieved within three weeks, may take longer if a larger area of the dermis is affected.
