Blood leaks into tissues under the skin and causes the black-and-blue color. As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity. A bruise on a leg usually will take longer to heal than a bruise on the face or arms. Most bruises are not a cause for concern and will go away on their own. Home treatment may speed healing and relieve the swelling and soreness that often accompany bruises that are caused by injury.
How long it takes a facial fracture to heal will depend on the type and extent of fracture and what other problems and treatment you had. Bruising and swelling usually takes 2 to 3 weeks to settle down. At this point, you will begin to look more normal. After this time the body will continue to heal itself inside. Unfortunately, you will need to be a patient.
