The most basic requirement for all surgery is good health. Other requirements are more subtle and should be carefully considered in discussion with your surgeon. Expectations of the surgery and of the surgeon must be realistic. A person considering facial scar revision must understand that there is no way to remove scars completely. The goal is to improve the appearance of the scar either by disguising it, relocating it, or minimizing its prominence. Skin color and type, age, and the type of scarring, are all important factors that must be part of the discussion prior to surgery.
Different types of scars respond to different plastic surgery techniques. Timing of surgery is another important choice. Some surgeons advise against any scar revision in cases of injury for a period that might extend up to a year after the injury. This interval allows the body enough time to heal fully.
