How to choose a needle for water needle?
There are two common needles for water-light acupuncture: water-light injection needle and painless needle. Let's first understand what is the difference between the two?
1. The difference between common injection needles and painless needles
Difference one
Our common injection needle is to pierce the skin and deliver nutrients to the depths of the skin. Most of the surface of the needle tip of the injection needle on the market is a bevel cutting process, which will cause pain during the piercing process. If there is a strong pain in the absence of anesthetics, it will be unbearable after repeated injections.

The invention of the painless needle is developed through the mosquito bionic technology. Compared with the tip of the injection needle, the improved syringe has a smaller contact area with the skin tissue, which reduces nerve stimulation and greatly reduces the pain caused by injection , Thereby improving the convenience of its use. It can realize all kinds of water and light injections. The face, neck, hands, and body can be injected without the use of anesthetics when the patient can tolerate slight pain.
Difference two
In terms of scene application, the needle lengths of common injection needles and painless needles are different, and the injection level will also be different. Common injection needles are longer and can penetrate directly into the skin mesodermal layer or even deeper. To use it on the whole face, you need to control the depth of the needle.
Painless needles, due to the shallow level of operation, are suitable for operation in sensitive areas such as around the eyes and neck. It should be noted that because the diameter of the needle tube is small, the painless needle is not recommended for injecting thick products, because the liquid medicine will not move, which will block the needle and cause the needle to burst.
For example, if you use a 32G needle to push the same product than a 30G needle, the 30G needle will be smoother than a 32G bolus.
