Non-surgical enhancements of the chin can be easily achieved with the injection of hyaluronic acid gels (Juvederm). The results are immediately noticeable, so you can feedback to your doctor "real-time" during the treatment as to the degree of enhancement you desire, whether subtle or more obvious. This will be the same as nasal bridge.
Unlike with surgical implants, hyaluronic acid gel is not permanent and gives a more natural result as no hard surgical implants can be felt. You can also "grow" your chin and nose gradually with hyaluronic acid gels, as the procedure is relative simple and can be repeated.
