Hyaluronic acid lip bead augmentation uses injections to inject hyaluronic acid into the lip bead area to support the lips by increasing the volume of subcutaneous tissue. When viewed from the front, the arching curvature of the upper lip is noticeable and three-dimensional after the injection, making the lips appear sexier and prettier. This approach is suitable for people who need to augment their lip beads or those who are dissatisfied with their own lip shape and want to change it through non-surgical methods. However, when hyaluronic acid is injected into the lips, the following risks need to be noted: 1. Once the injection enters the blood vessels, it may cause embolism or necrosis; 2. Due to the abundance of blood vessels in the lips, bruising and swelling may occur after the injection to a mild degree, which is a normal phenomenon. If the injection of substandard products may cause infection, lip swelling for a longer period of time; 3, excessive extrusion or activity will lead to displacement, and the injection is too shallow may lead to lip transparency. Hyaluronic acid filling lip bead recovery time after surgery is faster, basically will not affect normal work and life. However, hyaluronic acid can be gradually metabolized and degraded in the human body. Due to the special nature of lip injection, hyaluronic acid is more likely to be absorbed and degraded, and the filler effect will gradually disappear, so regular injection is needed. Generally 6-9 months to re-inject once, in order to maintain a good effect.
