Blunt cannulas are well known and their use is growing. This is because the medical aesthetics field is developing fast. More doctors and practitioners pay attention to quality injection tools. Among many tools, blunt cannulas are popular in aesthetics. Professionals often use them for injections like hyaluronic acid, botulinum toxin, and PRP. Sharp needles can also be used to finish injections. However, choosing the right blunt cannula helps injections go smoothly. For patients, blunt cannulas reduce discomfort and speed up recovery.
What is a cannula? The cannula in this article means the injection stool for fillers. Do you know why does it matter in aesthetics? So how to buy the right blunt cannula online? The answers will give your answer for this.
What is a cannula?
In aesthetics, people often call microcannulas simply cannulas. The main difference from sharp needles is the tip. Blunt cannulas have a blunt tip, not sharp. This lowers the chance of puncturing blood vessels and nerves. Therefore, injections with blunt tips are safer. A blunt cannula is a thin, hollow tube. It is made for precise injections under the skin. It works well for substances like hyaluronic acid, collagen, and PRP.
Blunt cannulas come in many sizes. They have short or long lengths. They also come in different gauges, such as 25G, 27G, and 30G. Different gauges suit different injection sites. For example, thicker and longer cannulas are good for cheeks, where large coverage is needed. Thinner and more flexible cannulas are better for delicate areas like tear troughs and nasolabial folds.
Flexibility for cannula is very important. A softer blunt cannula fits the face’s shape better. It avoids blood vessels more easily and reduce the blooding. This improves injection accuracy for the practitioners.
Why are cannulas important for aesthetic doctors?

Doctors used to use sharp needles. Sharp needles pierce easily but can hurt blood vessels. This causes bruises and hematomas. For aesthetic doctors, blunt needles offer clear benefits.
Safety is most important for any aesthetic treatments. Blunt needles rarely pierce blood vessels. They move carefully under the skin, avoiding vessels during injection process. This lowers bleeding and serious bruises. It reduces complications after treatment.
Blunt needles work well under the eyes. This is a sensitive area, so blunt needles are a good choice.
Patient comfort is better with blunt needles. One entry point can treat many spots. This means fewer needle holes and less pain. Many patients say recovery is faster. Their face looks more natural with less swelling and bruising.
Injection results improve too. Blunt needles allow layered injections. They spread material evenly in the target area. This is helpful for symmetrical areas like cheekbones, nasolabial folds, and tear troughs. Using blunt needles improves the aesthetic outcome.
Finally, blunt needles can lower costs. They need fewer skin punctures. This means less tissue damage. Recovery is shorter. Post-treatment care costs go down.

What qualifies as a qualified blunt needle for a Cannula?

A truly qualified blunt needle should meet the following criteria:
Blunt needles connect cosmetic injections to patients. Choosing the right tool can achieve twice the result with half the effort.
A truly qualified blunt needle must be safe, convenient, and compatible with the operator's injection habits.
You should choose a blunt needle made of high-quality material. Using medical-grade stainless steel can reduce various injection side effects, resulting in a smooth, burr-free, and deformed surface.
Secondly, the workmanship must be meticulous, and the connection between the needle tip and the cannula must be tight.
The flexibility of the blunt needle is also crucial. Too hard increases manipulation difficulty, while too soft can easily deform. Only a moderately flexible needle allows the doctor to easily control the needle's direction during the injection process.
The clarity of the scale also directly affects the judgment of injection depth. If it is unclear, it is easy to make mistakes.
Finally, confirm whether the product is FDA and CE certified. If the product has either of these certifications, its quality is guaranteed.
