Scars occur following any cut in the skin. Some scars are more noticeable than others, depending on their size, shape, and location on the body. Some scars can even cause functional problems, such as constriction or tightness, if they are located in a sensitive area, such as over joints. For this reason, scars can often be revised, or reconfigured, so that they are softer, thinner, and less noticeable.
Sometimes scars become thickened (e.g., hypertrophic scars) or grow out of the control (e.g., keloids), and can be itchy, uncomfortable, and unsightly.
Treatment options include scar revision, pressure dressings, and steroid injections.
