Method of injecting lip augmentation: 1. Hyaluronic acid injection lip augmentation Hyaluronic acid itself exists in human body, which not only has a perfect lip augmentation effect, but also has a certain moisturizing effect on lip skin. Hyaluronic acid is a derivative of collagen, and it is one of the necessary components to support skin elasticity. Lip augmentation with hyaluronic acid has almost no side effects. Generally, it can only last for 1-2 years, and it will be slowly absorbed by the human body, so it will not have any impact on human health. 2, collagen lip augmentation Collagen lip augmentation is the most natural lip filler, but it belongs to a tissue substitute, so you can't inject too much, otherwise there will be some adverse reactions and even lead to infection. But it should be noted that one third of people are allergic to collagen. 3. Lip augmentation with autologous fat This lip augmentation operation is to extract the fat from the subject's body and then inject it into the lips, but this lip augmentation operation will be more troublesome and requires anesthesia. But usually after a few weeks, you will get lasting sexy lips. This method of lip augmentation will be more reliable than injecting collagen, but it cannot be injected multiple times at a time. Because the injected fat needs the surrounding tissues to infiltrate into it to provide nutrition, if it is injected too much at a time, it will lead to liquefaction, which will seriously affect the effect of lip augmentation surgery. Choosing qualified regular hospitals and experienced experts can avoid problems and ensure the safety and effectiveness of beauty seekers.
