Hello, my friend, I'm a doctor in a plastic surgery hospital. At present, injecting hyaluronic acid is a safe and reliable method for rhinoplasty. Generally, the effect is quick after injection, but it needs the operation of a professional injection doctor. Hyaluronic acid is a linear macromolecular polysaccharide composed of disaccharide units and a natural substance in tissues. It widely exists in connective tissue, mucous tissue, lens of eyeball and sandwich membrane of some bacteria of vertebrates in nature, and plays an important role in dermis of human skin. It plays an important role in the overall maintenance of tissue structure and the transportation between cells, but hyaluronic acid lasts for a short time, usually eight months to one year, and most of it will be absorbed. If you want to have a long-term rhinoplasty, I suggest you inject Aibeifu, which is generally permanent according to your personal constitution.
