Skin-picking disorder, also known as excoriation, is a condition in which a person repeatedly picks at one’s skin, resulting in scars, open wounds, or sores.
The most frequent site of skin picking are the face, hands, and arms, although many people pick from other areas and from multiple body sites. People with skin picking may make efforts to hide the sores/scars by wearing make-up or wearing clothing that covers their skin.
People who experience skin picking often report trying to stop skin picking, but being unable to stop completely.
