Is there any danger of blunt injection of hyaluronic acid

Hyaluronic acid is injected with a blunt needle. Now, hyaluronic acid is mostly injected for plasticity, and the injection level is deeper and the area is larger. The traditional sharp needle injection is very demanding to the doctor, not careful can damage the facial nerve, causing complications, and the need for more injections also brings greater risk. With a blunt needle, you can avoid damaging the facial nerve. Even for a full injection, you only need two injection sites. So it's much safer to inject it. Most modern hospitals use blunt injections.

First of all, hyaluronic acid sharp needle tip is hard and has a strong acupuncture feeling, so there will be a slight pain in the treatment. Moreover, when large area injection is performed in layers, the pain will be more intense. By using a blunt hyaluronic acid needle injection, the sharp feeling is less, it is not easy to damage blood vessels, less bleeding, and the injection is safer.

Secondly, the needle of hyaluronic acid sharp needle is more sharp. If the doctor is not familiar with the facial anatomical structure, it is very easy to inject hyaluronic acid into the blood vessel, leading to vascular embolism and tissue necrosis. A blunt needle, which has a completely polished surface and a blunt head, can enter the tissue with minimal trauma, avoiding blood vessels completely, and leaving less chance of facial swelling and bruising.
