When the features are in balance, the line should just touch the chin. If not, a chin implant may help. Your facial plastic surgeon is best qualified to help you decide what procedures are needed to bring your facial features into balance. Take a long, hard look at what it's doing to your face. Smoking causes distinctive changes in the facial skin-so much so that facial plastic surgeons and skin specialists say they can tell whether a patient smokes just by examining his or her skin.
Smoking affects the blood supply to the skin, weakening it and causing it to age more rapidly.
As a result, smokers tend to have coarser, thicker facial skin that is more prone to wrinkling. Wrinkles around the eyes and vertical lines around the lips also are typically found in smokers. Unfortunately, facial rejuvenation surgery may not be advisable for some patients who smoke heavily. Because smoking reduces blood flow to facial tissues, the rate of healing is slower in smokers, and the risk of infection may be greater. Furthermore, continued smoking would tend to undo the benefits of surgery.
