The injection of hyaluronic acid can now be said to be the most basic plastic surgery program. Friends around me have basically injected it, so there is no need to verify the safety of hyaluronic acid, but how much do you know about the needle of hyaluronic acid~~ I believe you have heard of blunt needle technology, But do you really know what a blunt needle is? Which one should I choose, a blunt needle or a sharp needle? Check it out with dermax!
Sharp needle injection of hyaluronic acid
At present, most domestic injections of hyaluronic acid are performed with sharp needles. The sharp needle is like a bayonet, and it is easy to pierce the blood vessels and nerves if it is slightly biased. It is very easy to cause bruising and redness. One injection requires multiple injections, and pain is inevitable.
blunt needle injection of hyaluronic acid
The emergence of blunt needle injection technology perfectly avoids accidents in injection. Although many authoritative experts in the field of injection beauty call for “using a blunt needle to inject hyaluronic acid”. However, according to industry insiders, there are not many doctors who actually practice blunt needle injection of hyaluronic acid in China. The current situation in China is like this. Everyone knows that blunt needles are good, but they are not used much.
Now let me introduce to you what a blunt needle is. Now everyone knows about a blunt needle, but what is a blunt needle?
Details of the blunt needle:
Structural features:
- Flexibility; (you read that right, blunt needles are soft)
- The head is round and blunt, and the side is accurately cut by laser;
- Compatible with all types of screw syringes;
- Made of stainless steel.
Main advantages of blunt needles (compared to sharp needles)
- Reduce bleeding and bruising;
- Reduce patient discomfort and needle fear;
- Reduce the occurrence of risks such as intravascular injection;
- A puncture point can cover more area;
- Stimulate more collagen production;
- Faster recovery time for patients;
Applicable parts:
theoretically suitable for any part of the face, but mainly used for: cheeks/mid face, nasolabial folds and mandible/chin.

The hyaluronic acid pushed out by the blunt needle is smooth and straight, while the hyaluronic acid pushed out by the sharp needle is twisted and twisted, with different thicknesses. This subtle difference doesn’t make a big difference if it’s filling in a large area, but if it’s used in finer, shallower parts. For example, the filling of eye sockets, tear grooves and the modification of the bottom line will have a greater impact on the filling effect.
