Some of the aestheticians who have undergone hyaluronic acid rhinoplasty may experience a widening of the nose for the following reasons: 1. The candidate’s own nose has a poor foundation and requires a one-time injection of more hyaluronic acid to achieve the ideal rhinoplasty effect, but too much hyaluronic acid may lead to a widening of the nose; 2. Hyaluronic acid is over-injected because the tension of the skin is limited, and the excess hyaluronic acid will move to both ends of the nose which will lead to the widening of the nose; 3, the candidate wears too heavy glasses after surgery, which will lead to the displacement of hyaluronic acid to the brow and the side of the nose where the pressure is small, which will also lead to the widening of the nose; 4, the operation is not standardized and the depth and level are not in place, which will also lead to the widening of the nose and even other serious symptoms, but this phenomenon will improve with the metabolism of hyaluronic acid; 5, hyaluronic acid is a gel with high water content, especially the small molecules of hyaluronic acid. The support is not particularly good, not suitable for nose shaping sex, and the metabolism of hyaluronic acid with small molecular weight is fast, the cycle of replenishment is short, and repeated injections within a short period of time will also make the nose bridge wider.
