Is there any harm in blunt needle filling hyaluronic acid?

Since the dosage of hyaluronic acid used to fill the whole face is relatively large, there will be more needle holes injected into the face, so the probability of bacteria or viruses entering the skin with the needle holes will be increased. Once infected, oral antibiotics can be administered locally. If the infection spreads through the body in the blood, the patient will have fever and need intravenous antibiotics. 2. Vascular embolism: Since the whole face is filled with hyaluronic acid injection points, it is possible to inject hyaluronic acid into the blood vessels during the operation. The blood vessels will be blocked and the tissues at the blood supply site will be involved due to ischemia, and the local skin may become dark, and the patients will feel pain. If injected into a large blood vessel such as the ophthalmic artery, the patient can go blind immediately. 3. Local skin depression or protrusion. Due to the injection of the whole face, the absorption speed of hyaluronic acid in different parts is different.
