Many spas, cosmetic offices, and doctors offer dermal filler injection services to their patients. Each and everyone has their unique way of performing these procedures. Many of these offices, however, rely primarily on sharp tip dermal fillers. Many more are beginning to realize the many advantages of blunt tip Microcannula treatment. Even though the Microcannula technique is safer, effective, and less painful, doctors still use sharp-tipped needles.
In this article, we dive into the advantages and disadvantages of both Sharp Tipped needles and Microcannula technique. We want to give you a clear understanding of why so many practitioners are switching over and why patients love them for it. Sharp tipped needles aren't all that bad, however, with a few advantages still.
The Microcannula technique has reconstructed the cosmetic industry and offered doctors with a novel, innovative way of providing facial fillers injections. The approach allows physicians to slip the blunt tip cannula under the patient's skin sleekly and without tearing the epidermis. Patients looking to enhance their appearance can now do so without having to endure a painful procedure that has nasty side effects connected with sharp-tipped needles.
Essentially, microcannula is a modernized variant of the traditional hypodermic needles used to administer injection treatments. Rather than having a sharpened tip, this technique utilizes a dull end that makes an injection procedure much more pleasant. It has a bendable shaft, allowing it to move quickly compared to a traditional needle's stiffness that restricts it.
Microcannula (Blunt Tipped Needle)
At the source of the filler injection using Microcannula, your Doctor creates a minute entry point in your skin using a precise, sharp needle. This is a vital step since the Microcannula has a blunt tip and is incapable of penetrating the skin by itself. The insertion location is minimal and does not cause substantial pain or bleeding.
Then the Doctor skillfully inserts the Microcannula into the small opening and glides it under your skin to reach the sections of filler injection. The Microcannula then slides within the spaces connecting the tissue. It can be moved under the skin without any injuries to tissue. Patients typically do not feel much pain, if any, as the Doctor guides it under their skin.
Sharp Tipped Needle (Hypodermic Needle)
Sharp tip needles use a skinny, short, sharp needle to inject dermal fillers. Multiple injection points are required when using needles, which can increase the risk of hitting a vein. If a vein is hit with a needle, there's a higher chance of bruising after the procedure.
Using the Visual Analog Scale for pain assessment during the injections was quite different. The pain was described as 3 (mild) for injections with the microcannula. Patient discomfort is reduced to the level where topical anesthesia alone consistently suffices even for injection of the lips, and local nerve blocks are not necessary.
That pain level increased to 6 (moderate) for injections with the hypodermic needle. Bruising and ecchymosis were more marked following the use of the hypodermic needle.
Microcannula and Hypodermic needles scored pretty close to each other. Overall, the Global Aesthetic Improvements Scale (GAIS) results were excellent (55%), moderate (35%), and somewhat improved (10%) one month after the procedure, decreasing to 23%, 44%, and 33%, respectively, at the six-month evaluation. There were no significant differences in the GAIS score between the microcannula and the hypodermic needle. However, pain during the recovery can be higher after the use of sharp-tipped needles.
Utilizing Microcannula for filler injection offers numerous advantages over hypodermic needles, such as:
Advantages of Sharp Tipped Needle
Although the cannula method of injecting dermal fillers offers many benefits, there are still cases when sharp needles can be the right choice. When a minimal amount of filler for touchups are injected in small places like the cupid's bow of the upper lip or the temples, a needle is still the best option.
This study goes on to describe the potential of adverse effects. Of the 666 filler procedures using the microcannula technique, three treatments (0.5%) produced adverse events on the day of service, and during the two-week follow up 32 procedures (4.8%) produced adverse effects. In total, only 5.4% of treatments produced adverse events.
Cannulas may not be ideal for filling acne scars or injecting extremely fine lines located on the skin's superficial surface. Microcannulas, since they are blunt-tipped, cannot make their entry point, requiring the use of a sharp needle to start an entry point.
A risk concerning the sharp needle is not just penetrating the blood vessel but shooting the filler into it, leading to vascular occlusion. That can result in much more severe complications. Again, there are specific standards that practitioners take to ensure that this doesn't happen; however, it is something that must be acknowledged when using a needle.
Greater Pain. Using a sharp needle will create a lot of tissue, tearing only always. This tearing will cause pain for the patient and create a more unpleasant experience.
More Bruising. The needle won't slide easily and will cut veins and tear the tissue causing more bleeding, which will lead to bruising that takes a while to disappear.
Less Predictable. It's difficult for practitioners to know exactly what the damage the needle will cause.
There are many benefits to using microcannulas in sensitive invasive procedures. Here are a few examples of where microcannulas becomes invaluable to Doctors.
Vascular Compression
Technique matters greatly for evading vascular compression, but blunt tips make the probabilities of it happening much less possible. To stop unnecessary extrusion force when injecting fillers through blunt microcannulas that are invariably longer than the typical 13 mm to 19 mm sharp needles, a larger gauge is selected.
Ecchymosis
The risk of penetrating a blood vessel with a correctly used blunt microcannula is significantly reduced. Chances of ecchymosis, which may be recorded in regions such as the nasojugal fold, the upper eyelid, and the pre-jowl sulcus.
Collagenesis
It has been suggested that a blunt microcannula multiple times through an area may stimulate collagenases. This theory is persuasive by extrapolation from the collagenases observed with repeated back-and-forth passage of cannulas during liposculpture.
If you're a doctor who wants to purchase microcannulas, then stop by FACEMed's Store for all our available microcannulas. We carry multiple sizes to suit whatever your needs are.
As many cosmetic doctors and patients can attest, swapping the sharp needle for a blunt tip microcannula improves the outcomes of a procedure. The wide variety of microcannula choices has allowed doctors to perform both cosmetic and more invasive procedures harmlessly. The Microcannula technique is available in five different sizes. At FACE Medical Supply, you can find 18, 22, 25, 27, and 30 gauge microcannulas at various lengths. We sell high-quality microcannulas that will perform any filler injection task you need.

Not much is different. A cannula is boiled down to being a tube that does not end in a sharp point – but has a blunt tip. That blunt end is the primary difference between a cannula and a standard needle. A blunt- or smooth-tipped micro-cannula is also defined as one being used as an injection device that is inserted via a sharp needle created entry point with a micro-hole, or port in the side of the cannula shaft.
When it comes to FACE's aesthetic medicine, the words cannula and micro-cannula are frequently used in and are often interchangeable. You can check out our state of the art product here.
Regularly a distinction is made between the two terms based on the shape of the blunt tip. This is inaccurate, and a distinction is required so that doctors can classify it.
In other words, there is no difference if someone refers to using a cannula or a micro-cannula for subdermal injectable aesthetic treatments. However, besides this fact, there is still much uncertainty over the appropriate terminology, the exact definition of a micro-cannula, and the various product models available.
Here are some ways we at FACE Med classify a cannula:
Multiple ports are needed when using conventional, stiff, unflexible needles. Every injection port increases the likelihood of bruising. The sharp point on a traditional needle practically ensures patient bruising.
One main reason people avoid getting facial fillers is the fear that the needles used to inject the treatment will be too painful. Thankfully we have microcannulas to save you from your worries. To make injection treatments less painful, doctors have created a technique that takes the complications of pain mostly out of injection procedures.
Using microcannula, patients will experience less bruising, pain, and less tissue damage. Another benefit is that there is less of a chance of intravascular injections, and that supports both doctors and patients. Technology is changing, and with the use of microcannula, patients can relax a bit more when going in for an injection.
At FaceMed we want to provide the best and least painful methods for our clients so that you can go home and recover quickly and not dread your next injection. That's why we employ the best technology such as microcannula.
Faster. Now doctors will be able to perform your procedure more swiftly and with less pain on the patient.
Safe on blood vessels. Traditional hypodermic needles potentially damage small blood vessels, but using microcannula takes away this risk.
Minimal tissue damage. Patients encounter less bruising when using microcannula.
Faster recovery. Since there usually is only one insertion site when using microcannula, patients won't have to spend as much time improving.
Rejuvenated collagen. Thanks to the design of microcannula, patients will experience stimulated production of new collagen, which will improve their facial volume.
Minimal side effects. When facial injections are administered using microcannula, patients are likely to experience less, if any, side effects.
Well, that's probably because they're relatively new in the medical field, and it's going to take some momentum to overcome the decade's use of traditional needles. After doctors use microcannula, they tend never to want to go back to standard needles.
Studies on microcannulas have concluded that they're better than regular needles. Fillers are one of the most common minimally invasive treatments available today. Over 2.4 million injection procedures were performed just last year. Now, with this technology, millions of people can feel much safer receiving these injections.
