In a recent study conducted by The People’s Republic of China, multiple doctors tested various types of microcannulas to measure their differences and effectiveness. Let’s dive into what the study talked about and how they came to the conclusions that they did.
Soft-tissue augmentation is a mainstay of cosmetic enhancement for the face and has grown immensely in popularity. The American Society for Aesthetic Plastic Surgery has a long list of used filler types. They are calcium hydroxyapatite, collagen, fat, hyaluronic acid, polylactic acid, and polymethylmethacrylate microspheres. That’s a long list of choices, but of all these unique types of fillers, hyaluronic acid is used the most.
Why? Because of its hygroscopic properties, biocompatibility, and reversibility, hyaluronic acid is viewed as the most common dermal filler with which to restore volume loss.
Hyaluronic acid injection complications are local injection-related side effects that manifest as edema, pain, bruising, erythema, itching, and ecchymosis; the most concerning difficulty is vascular occlusion. It doesn’t sound too appealing at first. However, blunt-tipped can provide some reassurance.
Hyaluronic acid gels can be injected using sharp needles or blunt microcannulas. Studies have shown that the blunt microcannula with a side port presented improvements in mitigating pain and adverse effects, which has a degree of correction similar to a needle.
Some scholars state that the use of the microcannula is ideal for deeper nasolabial fold and lip augmentation and in areas requiring a larger filler volume, such as the mid-face and jowl regions.

SHOPIt’s clear that micro cannulas have superior results compared to sharp-tipped needles, but which microcannulas work the best?
Microcannulas’ use is limited by the injection area and the physician’s choice, but the differences between microcannulas constructed by different manufacturers have not been carefully investigated.
This study was designed to compare the microstructures and properties of different microcannulas by several trials and provide guidance for clinical application.
Materials
The study chose nine types of microcannulas that are widely used internationally. These microcannulas are available in gauges ranging from 18 to 30; the 23-, 25-, and 27-gauge. All microcannulas have a blunt tip with a precision laser-cut lateral side port for filler extrusion and a plastic pedestal that fits on any Luer lock syringe.
The physician may choose a different gauge or length because of the requirements of injection, including the technique being used and the area being filled.
In this study, all microcannulas are 25-gauge.
Methods
Scanning Electron Microscopic Images of the Microcannulas.
The microcannulas were sectioned and mounted onto a stub. A scanning electron microscope was used to obtain a high-definition image of the blunt tip, side injection port, and inner surface through each microcannula’s side port. For each microcannula, three new microcannula tips were measured.
The microcannulas had various tip shapes. The microcannula’s hole was oval (microcannulas 1, 3, 4, 5, 6, and 7), pointed rounded (microcannulas 8 and 9), or a unique form (similar to the rounded trapezoidal structure) (microcannula 2).
The ports of the Microcannulas were mainly oval, but the lengths were different, and some ports were three times larger than the others. There were two port edge forms; some (microcannulas 1, 2, 3, 4, 5, 6, and 7) were smooth, and others (microcannulas 3, 8, and 9) were rough. The edge form depends mainly on the technical process, and the laser cutting generally results in a smooth shape.10 For the inner surface, most microcannulas (1, 2, 3, 4, 5, 6, 7, and 8) had inner surfaces with a cord-like structure; only microcannula 9 had an oval structure inner surface, and the difference demonstrated that they had different surface processes.
Material
The inner surfaces of some microcannulas (2 and 8) had visible impurity, and the exterior of microcannula 7 had a stripe-like structure.
Only microcannulas 1 and 9 met the requirement concerning carbon composition; the other microcannulas had a higher composition with a significant difference. For other elements, all microcannulas met the American Society for Testing and Materials requirement; microcannula 9 was the only one that fits the American Society for Testing and Materials composition standards for all elements.
Elasticity
The elastic moduli of microcannulas 2 and 7 are smaller than those of other microcannulas. The yield strength was analyzed; the yield strength of microcannula 9 was the highest. There was a significant difference in the mechanical properties among the microcannulas.
Injection Speed
Microcannula 1 had the highest speed compared with other microcannulas, and microcannula 9 was the slowest one in the test. The difference in the time spent between microcannula two and microcannula 9 was more than 7-fold.
The result of the injection force test showed that some microcannulas could easily puncture the aorta with a higher force; it was difficult for microcannula 4 to puncture the aorta.

SHOPCompared with the traditional sharp needle, there is a definite advantage for blunt microcannulas to reduce patient discomfort, bleeding, and bruising, attributable to its rounded tip.
In the electron microscopy results, there are nine types of microcannulas, which are mainly oval, pointed, or rounded, and microcannula 2 exhibits a unique form. From the point of stress, it is microcannulas 2, and 7 show significant differences with others.
It was more comfortable for the sharper microcannulas to penetrate the tissue, and the patient may feel more comfortable. By contrast, when blunt microcannulas meet dense tissue, such as ligaments and fascia, there will be a certain degree of discomfort from the tissue shift caused by the resistance. However, a blunter microcannula has a lower probability of piercing the vessels and is therefore safer.
This issue is further investigated in the vessel piercing test. The results show that the tips of microcannulas 2, 8, and 9 are sharper, and the others are blunter.
For microcannulas 2 and 8, the carbon content is higher than the American Society for Testing and Materials standard level, and the carburizing treatment of the microcannula surface is mainly considered. Carburizing treatment is a chemical heat treatment process in which the steel is put into the carburizing medium to be heated and preserved, making the carbon atoms enter the surface.
Generally, the surface carbon content increases with increases in the carbon atmosphere concentration, diffusion time, and diffusion temperature, whereas the internal carbon content is less affected. As the carbon content increases, the hardness and wear resistance of the material is often higher, as is the brittleness. The plasticity and toughness are worse, which may lead to a fracture in bending and stretching deformation. Microcannula 9 is the only one that fully conforms to American Society for Testing and Materials standards.
It is essential for physicians to feel the injection during the operation; therefore, the study designed an injection speed experiment that was aimed at determining the time of each microcannula injection, and the volume of hyaluronic acid under constant pressure indirectly reflected the smoothness of the operative process. Smoothness is related to the inner diameter and the smoothness of the inner wall.
From a fluid mechanics standpoint, all other things being equal, the time spent for the liquid to pass through a microcannula depends on the larger area of the inner section and the side port section. When the inner part is larger than the side port section, the outflow of liquid is restricted by the side port, and the inner diameter makes no difference and vice versa.
For microcannulas 1, 2, 3, 5, 7, 8, and 9, the inner section is larger than the side port section, and, along with the reason for differences in smoothness, the result of injection speed can be explained. When changing between different microcannulas, physicians should be fully aware of the smoothness of different microcannulas. They should first adapt to the actual injection handle and then inject to avoid making the injection volume too large or too small. Although injection technology of hyaluronic acid has become increasingly mature, complications are frequent.
One of the most serious is the microcannula piercing the blood vessels, which can lead to vascular embolization. There have been many cases of embolism reported in the literature that have resulted in skin necrosis and blindness. A competent physician must, as much as possible, reduce the risk of vascular embolism to zero. On the one hand, we should be familiar with the anatomical structure of different injection areas to avoid blood vessels during the injection.
On the other hand, it is also imperative to choose a suitable injection tool. A few studies have shown that the microcannula with a blunt tip is better for avoiding punctured blood vessels than a sharp tip. The results showed that microcannula 4 struggled the most to penetrate the blood vessels, and the relative safety was high.

Comparison of Microstructure and Properties of Different Microcannulas for Hyaluronic Acid Injection.
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.

SHOPThe 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.

SHOPThis 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.

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. The results show that microcannula injections are the future.
These microcannulas can be safely employed with a variety of cosmetic methods and fillers of any type and viscosity, including Lip augmentation, soft augmentation of the facial filling, plumping cheeks, wrinkle-reducing, plumping cheeks, reducing saggy skin and bags under the eye.

Simply put? The clinical benefits. Benefits from blunt microcannulas include elimination or near elimination of the risks of accidental intravascular injection. An intravascular injection is an injury to vital neurovascular structures within the areas of injection. Many researchers agree that a blunt microcannula of 27 gauge or above is unlikely to puncture blood vessels or nerves if it is used with proper technique. A Microcannula will push tissue aside as it traverses the path of least resistance through the tissue. So what other benefits do Microcannulas have?

SHOPTechnique matters for avoiding vascular compression, but blunt tips make the chances of it happen far less likely. To prevent excessive 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.
In general, a microcannula of 27-gauge or larger diameter is used in place of a 30-gauge sharp needle, and a microcannula of 25 gauge or larger diameter in place of a 27-gauge sharp needle. The decreased extrusion force facilitates the increased flow of filler products that can cause the deposition of inappropriately large filler boluses if the injector is unused to the small volume micro-threading technique that is best suited to microcannulas.
The decreased or eliminated the risk of piercing a blood vessel with an appropriately used blunt microcannula compared to sharp needles results in a significantly reduced risk of ecchymosis, which may be particularly noted in regions such as the nasojugal fold, the upper eyelid, and the pre-jowl sulcus. In the researcher’s experience, ecchymosis with blunt microcannulas is minimal and, for many patients, nonexistent.
If ecchymosis does occur, it may be at the insertion site of the sharp pilot needle, or in areas of increased tissue resistance if the microcannula is applied with inappropriate force. Increased tissue resistance may be due to fibrosis, in patients who have previously had face-lifting surgery or multiple injection sessions with collagen-stimulating volumizers such as PLLA. These situations may be considered relative contraindications to the use of blunt microcannulas.
According to researchers, the tolerability of blunt microcannulas is equal to or greater than that of sharp needles. 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. There may be some discomfort during the injection, especially if a microcannula is passed multiple times through a zone of tissue fibrosis. Some patients dislike the noise of a blunt microcannula passing through tissue, and we recommend forewarning patients of this and playing music to provide auditory distraction during the injection procedure.
It has been suggested that the back-and-forth passage of a blunt microcannula multiple times through an area may stimulate collagenesis. This theory is persuasive by extrapolation from the collagenesis observed with repeated back-and-forth passage of cannulas during liposculpture. However, the researchers note that collagenesis induced by liposculpture typically results from a much larger number of “tunneling” passes through the tissue than would be performed when injecting alloplastic fillers with microcannulas.

A huge reason people avoid getting facial fillers is the fear that the needles used to inject the treatment will be too uncomfortable. Luckily we have microcannula. To make injection treatments less painful, physicians have devised a technique that takes the complexities out of facial filler procedures.
Essentially, microcannula is an updated version of the traditional hypodermic needles used to administer injection treatments. Rather than having a sharp tip, this method uses a blunt end that makes your injection treatment much more comfortable. It’s has a flexible shaft, allowing it to move quickly compared to the stiffness of a traditional needle.

Maybe you have decided to get fillers, and now the question is what sort of fillers do you need. As the mid-face ages, it begins to sag because the skin gets a little looser, and the tissue has less support. This would be a sign that you’re the right candidate for facial fillers to lift the sag and create a more youthful, renewed look. What’s next? You make your appointment and then schedule your procedure.
The physician first makes a small entry point in your skin using a fine needle. This is a crucial step since the Microcannula has a blunt tip and is unable to pierce into the skin on its own. The entry spot is very shallow and does not cause much pain or bleeding for patients.
Then the doctor carefully inserts the Microcannula through the little opening they created with a sharp needle.
The doctor then guides it under your skin to the sites of the intended injection. Along the way, the Microcannula gently slides through the between the tissues. The needle can be moved under the skin without causing any damage to the tissues and the patient most often do not feel any pain, only pressure, as the doctor moves it under their skin.
If a doctor was to fill under a patient’s eyes, they make a small hole either next to the lip or over the cheekbone and move the needle in and up your cheek, under the skin. I know, it sounds scary, but because the one hole is the only site of injection, it closes within two hours and hurts less because it’s anesthetized.
The Microcannula technique has transformed the cosmetic business and presented doctors with a unique, innovative way of offering facial fillers injections. The method enables doctors to slide the blunt tip cannula under the patient’s skin smoothly and without ripping the epidermis. What this means is that 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.

SHOPSharp Needles. Up until now, filler injections have been performed utilizing the hypodermic needle, a sharp-tipped tool that comes with several side effects. Since the point is sharp, inserting it into the skin creates a higher risk of cutting tiny blood vessels and producing harsh bruising. It’s not common, but it worth mentioning that by injecting a filler solution into the vein – and inevitably into the bloodstream – the patient could undergo a more severe reaction.
Microcannulas establish an improved form of the conventional hypodermic sharp needle, designed to eliminate all possible complications associated with sharp tips. The secret lies in the blunt end that makes both the injection of dermal filler and fat transferal methods considerably more straightforward and less strenuous on the patient. Microcannulas used for filler injections are relatively new. What makes them popular with doctors is their easy to use, simple utility, great results, and patient satisfaction. This has transformed them into a popular choice throughout cosmetic clinics and spas.
The round tip, along with the flexibleness of the Microcannula technique, presents numerous benefits over conventional sharp needles:
As many cosmetic doctors and patients can prove, trading the sharp needle for a blunt tip microcannula dramatically increases the outcomes of a procedure. The wide assortment of microcannula choices has allowed doctors to perform both cosmetic and more invasive procedures safely. The Microcannula technique is available in five different sizes. At the FaceMed store, you can find 18,22,25,27, and 30 size gauge microcannula’s at various lengths. We sell high-quality microcannulas that will perform any filler injection task you need.

Lip augmentation has developed momentum in recent years and has rapidly become one of the most popular bodily enhanced sites. Proper lip augmentation is often about looking at the dimensions of a patient’s face to determine which shape best complements the rest of their facial features.
Each practitioner will have a unique treatment approach to achieve the desired results. However, each will either use a hard needle or a microcannula for injection. This leaves the question: Which is better to inject with a needle or cannula? The cannula is definitely what many doctors prefer and here’s why.

SHOPSimilar to needles, micro cannulas have a hollow bore, allowing the filler to pass through into the tissue. The difference is instead of a sharp tip like needles, cannulas have a blunt end. The method entails dulling the skin with ice, then injecting a small amount of local anesthetic beneath the skin with a tiny needle. When the skin around the lip is numb, a needle pierces the skin, and then the cannula is threaded into the puncture site providing access for filler placement.
There are many benefits of using a blunt-tipped cannula for lip enhancement, including:
The choice to use a microcannula depends on the preference of the doctor. Although needles are easy to use, they are more likely to cause bruising or transfer filler substance into a blood vessel where they are not wanted.
The accuracy of micro cannula is one of the most sought after abilities for facial injections. The Microcannula’s allow there to just be one small point of entry for the needle. The flexibility of the microcannula then allows it to travel to various locations where the filler can be injected. This allows for minimal tissue damage and almost no pain.

Regardless of what the Doctor is using the utmost care should always be taken to ensure safety for the patient. For example, the tear trough region under the eye is more likely to bruise with a needle. Although not foolproof, microcannulas significantly reduce the risk of bruising and unintended injection into a vessel. Cannulas can also reduce trauma, discomfort, and swelling.
Fat deep within the skin loses volume throughout the natural aging process. Facial bones even tend to lose their size over time. That’s why soft-tissue fillers have become increasingly powerful products for facial rejuvenation to regain that lost facial volume.
To get a more natural-looking result with fillers, it’s essential to perform deep volumetric injections at precise sites. Supraperiosteal placement is best performed with a sharp needle or a microcannula. However, which needle is the best when performing these deep volumetric injections?

SHOPOne significant difference is needle flexibility and control. While sharp-tipped needles are naturally stringent, cannulas provide a more flexible option. This allows them to move more freely and easily when injecting. The flexibility also will enable them to not “cut” more than needs to so that the injection does the least amount of damage as possible. But
Too much flexibility can sometimes be a bad thing. To overcome this, the micro-cannulas offer a solution which is more rigid than many other cannula products, yet still more flexible than any stringent needle. The rigidity allows practitioners, even more, control over their movements in a more predictable and always manageable fashion.
Sharp needles require multiple entry points to deposit the chosen product in a bolus or linear fashion across a given area. Cannulas can be used through fewer entry points to deliver the product. This is because they can be pushed through the tissue freely and easily, without cutting. This makes treatment quicker and less painful without repeated needle entry.
Patient comfort is another plus to microcannulas due to them being a less “invasive” to sharp needles. Traumatic treatments become imperative for practitioners. Studies show that patients recover faster with microcannulas and notice less pain and swelling after the injection. Even without the added benefits to the user, the fact that patients experience more comfort is enough to warrant using cannulas. At FACE, we provide multiple sizes of microcannulas so that you can be ready to serve whatever your patients need.
The research performed compared Sharp Needles to Cannulas. During testing, researchers set out to analyze the safety profiles of both injection techniques. Researchers injected cadaver heads with dye material and soft-tissue fillers at multiple aesthetic facial sites on the supraperiosteum.
Afterward, the cadaver was dissected for the measurement of dye and filler placement. The researchers discovered the non-traumatic cannula technique resulted in the product remaining confined to the deep anatomic layers compared with the sharp needle technique where the material was found in various anatomic layers that were not intended.
Researchers continued their tests and discovered that both technique’s results were consistent for all facial sites. In the end, microcannula showed more precision in the placement of the injection. While the sharp needle, the material was injected, moved in a recessive direction along the path of the needle path, ending up in multiple anatomic layers. The sharp needle technique also showed a higher complication risk with intra-arterial injection occurring, even though the needle tip was positioned on the periosteum/
