Hyaluronic acid rhinoplasty is a type of injectable rhinoplasty, the advantage of which is that no incision is required and the back of the nose can be augmented by injection only. However, hyaluronic acid is a mucopolysaccharide polymer that will be metabolized over time, so it does not last long and requires repeated injections. Exactly how long a rhinoplasty can last after hyaluronic acid augmentation has a lot to do with the material of hyaluronic acid. The hyaluronic acid currently on the market is divided into two kinds: one is the commonly used small particles of hyaluronic acid, small particles of hyaluronic acid maintenance time is relatively short, about six months to a year. The other is the large particle hyaluronic acid, which has a relatively long maintenance time, reaching one and a half to two years. However, the specific choice of hyaluronic acid needs to be decided according to individual needs. If you only hope to get short-term effects, you can choose small particles of hyaluronic acid, which are absorbed more quickly. If you wish to maintain long-term effects, you can choose large particles of hyaluronic acid. In addition, the maintenance time of hyaluronic acid rhinoplasty is also related to the patient’s replenishment of hyaluronic acid. If the candidate injects hyaluronic acid several times and pays attention to maintenance after surgery, the effect of rhinoplasty can be maintained for a longer time.
