Fillers are simply hyaluronic acid gels that are injected into the nose. When injected they are effective in plumping and achieving a better nose shape. These hyaluronic acid gels are very good at retaining moisture and common name brands include Restylane, Perlane, and Juvéderm. Hyaluronic acid is also a naturally produced by the body, so the chances of an allergic reaction are low. One of the greatest advantages of getting nose fillers is that the procedure is completely reversible. The results last only approximately 12 months and then nose will return to the pre-procedure shape. Also, since there are no incisions involved, the treatment results in no scarring. There is also no down time involved and you can go back to your normal routine immediately following the procedure. Direct sunlight and humid areas should also be avoided for some time post treatment.
