Thanks for your good question. Restylane Silk is a soft, smooth filler that tends to work best on delicate areas like the lips and under the eyes. This product would be unlikely to give you the positive changes in the nose you want. That said, there are other excellent fillers we use for non-surgical rhinoplasty, including products in the Restylane and Juvederm line. Results usually last anywhere from six months to a year, depending on the amount used, the specific treatment area and the speed at which your body absorbs the hyaluronic acid in the mix. Make sure you are working with a board-certified cosmetic dermatologist who has performed many non-surgical rhinoplasty procedures to ensure the best possible outcome.
