What is Blunt Tip Cannula?

Skincare and medical treatments are advancing and turning out even more urbane. We have numerous non-invasive procedures, all designed to enhance your skin’s beauty. So, if you’re looking to solve a dermatological condition or looking to improve your poise, you have a set of choices. And  most of these choices demand the use of a needle or cannula to complete the procedure.

What is Blunt Tip Cannula

With these numerous options, every cosmetic hospital, or office has their own remarkable ways of conducting it. Most of them depend on sharp tips for injecting a dermal filler, thread lifting, or Botox, among others. However, there are various types of blunt tip cannulas today to make the process safe, efficient, and with little to no pain. So this blog discusses what blunt tip cannulas are and why you should opt for them. Read on to find out more.

What Is the Blunt Tip Cannula Technique?

Blunt tipped needles are also called microcannula. They are made of blunt tips. These are used to inject dermal fillers safely. So blunt tips are a better version of the old-style hypodermic needles for conducting cosmetic procedures that need injections. They have a flexible tube that makes it move swiftly in the skin, unlike the old-style needles that are highly limiting.

Besides, it’s a newer technology that uses a less-invasive way for dermal filler injection. Unlike many other aesthetic surgeries that use sharp tips, blunt tips have little to no downtime after the operation.

This cannula method of injecting dermal fillers allows the plastic surgeon to create an entry point into the patient’s skin smoothly and this will reduce bruising on the epidermis. So if you’re looking for a natural look without suffering a throbbing process that includes some horrible side effects linked to sharp needles, then this is the way to go!

How Blunt Tip Cannula Works

To complete a plastic surgery using blunt tip cannula, the cosmetic surgeon:

  • makes a small entry point in the skin by using a specific needle since the microcannula has a blunt tip that doesn’t penetrate the skin by itself. This ensures negligible pain or bleeding.
  • Then slowly slide the microcannula under the skin.  He’ll continually slide it until they reach the area with the filler injections. And while there’s movement in the skin tissue, there’s little to no pain. Blunt-tipped cannulas are also supple and reach a wider area.

How Different Are Blunt Tip Cannulas from Sharp Tipped?

While blunt tip cannulas have blunt ends, other cannulas and needles have sharp tips that utilize a thin short sharp needle for injection of fillers. Also, these cannulas allow multiple needle injection points to conduct the procedure. And this enhances the chances of hitting a vein. As a result, there’s the risk of bruising your face after the process. It is the exact opposite with blunt tip cannulas.

How Painful Is a Blunt Tip Procedure?

According to the pain assessment by a Visual Analog Scale, blunt tip procedures range at the scale of 3; meaning pretty mild. It means that topical anesthesia is enough to stop the pain and discomfort. Lips injections and local nerve blocks are not needed.

Sharp tipped cannulas, on the other hand, have a pain level of six. There’s a higher risk of bruising as well as lots of discomfort.

Benefits of Blunt Tip Cannula

Blunt tip cannulas have incomparable benefits to other needles such as:

  • Highly flexible, enabling smooth, swift, and accessible treatment with slight pain in several areas through a single-entry point. Areas like the lips, cheeks, nose, marionette lines, etc., are advantaged by this.
  • It causes a slight risk of harm to the blood vessels, unlike sharp tipped needles that trouble the small blood vessels. Also, blunt tips push the blood vessels aside, preventing them from harm.
  • It has a fast recovery time. Because the blunt tip uses a single insertion, there’s no risk of bruising, resulting in less downtime. However, sharp needles can cause tearing, leading to bruising.
  • Tissues are spared from damage. Why? There’s less bruising with a blunt tip cannula.
  • Stimulates production of new collagen. The blunt tip design stimulates the production of new collagen for desired results.
  • Fewer side effects. Any facial enhancement with microcannulas results in fewer side effects, if any.
  • More reliable method: although both sharp needles and blunt tip cannulas may injure a vein or artery, blunt tips tend to be safer.

What Are The Downsides?

Micro cannulas might seem like a great idea for a natural look, but they have some real downsides that you should consider before jumping on the bandwagon.

Microcannulas offer less retreat space than the regular scalpel for making an incision and placing injection sites. And this increases the risk of error and scarring. For that reason, they aren’t perfect for filing scars of acne, body contouring, skin tightening, or incising fine lines on the skin’s shallow surface.

Application of Blunt Tips Cannulas

Blunt tips offer innumerable advantages during cosmetic skin treatments. They include reducing wrinkles, facial filling, skin resurfacing, facial rejuvenation, lip augmentation, plumping cheeks, reduction of loose skin and bags under the eye, to name but a few. You can use a blunt cannula with numerous other methods and fillers of different types and viscosity.

Vascular compression

Blunt tip cannulas offer the best results for dermal filling and filling. They immensely prevent vascular compression from occurring. When fillers are injected using a longer microcannula, say longer than the 19mm sharp needles, you can avoid pointless swellings.


Collagenesis is a natural process of stimulating collagen production without causing harm. We have seen this in liposculpture. Microcannula blunt tips have proven to be the safest way to stimulate collagen.


Ecchymosis is the staining of the skin that makes it purple due to bleeding under the skin from bruising. The traditional needles are fond of these cases. However, the blunt tip cannulas for filler injection produce desired results without harm. They have reduced the chances of piercing a blood vessel to cause ecchymosis. Ecchymosis occurs mainly on the upper eyelid, the pre-jowl, and the nasolabial fold.

Types of Blunt Tip Cannulas

By now, you know how efficient blunt tip cannulas are in contrast to sharp-tipped ones. However, there are various types of blunt tip cannulas? In an electron microscopy study by Facemed Store, there are nine types of blunt tip cannulas further subdivided into oval, pointed, or rounded microcannulas.

These cannulas vary in size, material, and specific application.


As earlier indicated, there are nine cannulas available in scales varying from 18 to 30, 23, 25, and 27 gauges. And though these cannulas are blunt-tipped, the material differs. But all have exact laser-cut on the adjacent side port for extrusion of the fillers. Also, they are made of a plastic base that matches any Luer lock syringe.

Moreover, blunt tip cannulas have varying carbon compositions. There are those with more composition and others with less composition. But all must comply with the material requirements for cannula manufacturing.


Elasticity largely varies in blunt tip cannulas. There are some with small elastic moduli and those with high elastic moduli. The yield strength differs too. We have weak and robust based on the mechanical properties of the microcannulas.

Injection Speed

Most importantly, blunt-tipped cannulas differ in speed. While some are swift, there are those cannulas that require slow injection speed.

Where to Purchase Blunt Tip Cannulas

You’ll never go wrong choosing a blunt tip microcannula over the sharp needle. Blunt tip cannulas provide the desired results for both patients and doctors. Since there’s numerous microcannula options, it’s easy to conduct cosmetic procedures and even invasive procedures with no harm.

And since the blunt tip technique comes in five various options, i.e., 18,22, 25, 27, and 30, yet varying in length, there’s always one that’ll suit your needs. For that reason, we at Yastrid sell high-quality blunt tip cannulas that achieve all filler injection procedures. We’re the future of medical aesthetics.


While there are many cannulas for conducting medical procedures, doctors and dermatologists have found light in blunt tip cannulas. As mentioned, blunt tip cannula is a revolutionary new micro-needling device that is the first non-surgical, painless alternative to injectable fillers. It works by using tiny perforations in the skin to inject active ingredients deeply into the layer of cells beneath. They can work on rebuilding collagen, smooth wrinkles, and slow down further aging of the skin.

Therefore, for the appropriate application of these cannulas, doctors should have access to various medically approved cannulas for each procedure. This is to ensure they meet all patient’s needs. You can get these cannulas at Yastrid. For your micro cannula needs, check us out!
