Why is a blunt needle safer than a sharp one?

The needle of sharp needle is like a bayonet. The tissue it passes through will first be "cut" by it, which is easy to cut the blood vessel and lead to bleeding. If the filler is injected into the blood vessel, it will cause skin necrosis and serious problems such as blindness, cerebral infarction and myocardial infarction. At the same time, large area injection with sharp needle requires multiple injection points, easy to increase discomfort and discontinuity of the transition site.

The whole needle of blunt needle is made of flexible and elastic stainless steel. The circular blunt tip can move smoothly in the soft tissue and reduce postoperative swelling. And its elastic needle can better meet the needs of the face arc, so it can create a more even and natural face line with the least amount of needle holes.

Most importantly, when the blunt needle tip hits blood vessels and nerves, it will naturally slip away without puncturing, greatly reducing the chance of bleeding, bruising and nerve damage. The circular exit is designed on the side of the needle, so that even if the blood vessel is punctured, the filling will not be immediately injected into the blood vessel, preventing the injection of the filling into the subcutaneous blood vessel to cause vascular compression or vascular embolism, thus reducing the chance of skin necrosis.
