Hyaluronic acid injection into the tip of the nose is not recommended. The reason is that if you inject hyaluronic acid into the tip of the nose where arteries are dense, the injection agent may enter the blood vessels and the hyaluronic acid may become a blood clot and stop blood flow. Many medical institutions do not recommend injecting hyaluronic acid into the tip of the nose because there is a risk of necrosis at the injection site if blood flow is impaired.
