The difference between a blunt needle and a sharp needle
Mar 03, 2022
The main difference between a blunt needle and a sharp needle is the position of the needle. The needle of a blunt needle is round, and the needle of a sharp needle is beveled. A blunt needle will not directly pierce the skin, and needs to be opened, while a sharp needle can directly pierce the skin.
When injecting into the face and other parts, the blunt needle will not damage the blood vessels, so it will not penetrate the blood vessels during the injection process, resulting in the occurrence of vascular embolism. Sharp needles are sharp at the tip, so this is possible. Relatively rich blood vessels need to be injected with a blunt needle. If there are relatively few blood vessels, a sharp needle needs to be used for injection, which can achieve very safe protection. Therefore, the beauty seeker should communicate with the doctor according to their own situation and choose these two kinds of needles.
