Dermal filler injections have quickly become a well-known face rejuvenating procedure among both doctors and patients. Cosmetic injectables such as hyaluronic acid are efficient techniques to manage the symptoms of aging and other skin-related problems. They are less traumatic than laser ablation and have longer-lasting effects.
Yet, not all dermal filler techniques are similar. There are particular methods for delivering fillers to the treated regions that are considerably safer than others. The adoption of using a micro-cannula rather than a needle for fillers is among the most merit-proven procedures in applying injectables.
What Are Micro Cannulas?
Microcannulas are essentially enhanced versions of the standard hypodermic needles used to give injectable treatments. Instead of a sharp needle tip, this technique uses a blunt tip micro-cannula needle for fillers, making injecting considerably pain-free and effortless. Moreover, this approach avoids the most prevalent adverse effects and allows better access into the skin’s tissue layers, enhancing the procedure results. The innovative method lowers the chance of problems occurring during the process, such as a vascular injury.
Previously, using sharp needle fillers was the preferred medical tool for how doctors traditionally delivered such treatments into the underlying skin regions until recently. However, cosmetic injectors are increasingly using innovative blunt-tipped needles called micro-cannula, often abbreviated as a cannula.
Based on certain factors, the injector decides which micro-cannula filler is the most suitable. This article will tell you everything you need to know about how to use a cannula for fillers and how to look for the best microcannula fillers?
Injecting fillers through this superior approach is one of the most successful and safest anti-aging procedures available that tend to reverse the effects of years of aging in minutes.
Reasons why a blunt tip microcannula is ideal for non-surgical rejuvenating procedures? Before getting into the basic idea, let us see how deep injections and cosmetic fillers benefit from a microcannula.
Recent advancements in medical technology have increased the popularity of microcannula injectable, methods providing several advantages. While this approach works, a blunt-tipped cannula and the microcannula technique as a whole can elegantly avoid various drawbacks by utilizing a more effective injection tailored especially for these procedures.
Benefits of Microcannula
Here are some advantages of adopting microcannula injections over sharp tip hypodermic needles:
1. Flexibility and only one or a few entrance points required
The concern of using a sharp needle in a dermal filler injection is that if the treatment involves several filler spots, your skin would have to suffer numerous pointed tip instillations. It entails increased damage to the surface of the skin and the risk of deep tissue injury. The cause for this is because a sharp tip cannot go further than the tissue after the primary injection.
Doing so raises the danger of perforating a blood vessel. Needles may often be a lot short and stiff to effectively access the deemed necessary treatment regions, which implies that even in the hands of the most trained medical professional, your outcomes may be less than you desire.
Thanks to the flexible shaft, microcannulas, on the other hand, can treat a vast region with a single injection site. They can merely nudge any blood vessel aside rather than piercing it. Similar to how you might glide your fingertips through pages of a book. It also allows microcannula infusions to cover more parts surrounding your skin without scarring or bleeding.
2. Greater control over dermal filler injections
Considering the rheological properties of any face filler during a hypodermic injection is essential because it determines the treatment’s early apparent outcomes.
The manufacture of a sharp-tipped needle requires injectables to come out from the skin immediately. They frequently render this application difficult as deep injections sometimes result in additional cosmetic fillers infused in the tissue more than needed.
Yet blunt-tip microcannula can retain beneath the dermal layer substantially for a longer duration than a typical hypodermic needle, giving the injector better control of the filler process. The doctor may inject hyaluronic acid or other filling materials through the lateral hole-like opening near the tip.
It was especially beneficial for dermal filler procedures that addressed problems regarding nasolabial folds, enabling more control over the amount of filler material injected within the skin layer.
3. Less post-operative care is necessary
Even though dermal filler treatments are non-invasive cosmetic processes, sharp-tipped needle injections nevertheless necessitate some follow-up care due to the bruising and inflammation they cause underneath the skin.
By making use of a blunt microcannula, you may continue your routine tasks nearly soon after the procedure. Since a blunt microcannula can restrict vascular entry through the skin by shifting the blood vessel sideways, there is very little chance of its damage or any subcutaneous problem. In comparison to a sharp-tipped needle, this result in much less delay time needed for comprehensive recovery.
4. Formation of new collagen
Furthermore, the purpose of the microcannula design is to promote the synthesis of new collagen surrounding the treated region in an attempt to increase the volume of your face. It may apply for among the following examples of fillers by this innovation:
- Microcannula lip filler
- Microcannula under eye filler
With the growth of this method, you can safely opt for a wide range of cosmetic treatments and fillers of any type having various viscosities. These include:
- Lip enhancement
- Reduction of wrinkles
- Puffy cheeks
- Drooping skin
- Tear trough or undereye bags
- Marionette lines often referred to as laugh lines or nasolabial folds
- Any other non-surgical rhinoplasty
- Jowl areas
For example, tear troughs can dull out the beauty and glow from your eyes, leaving a dreary and tired appearance. Getting micro cannula under eye filler rejuvenates your eyes and makes them look less exhaustive.
Now, coming back to the main question ‘how to look for the best microcannula for fillers, you’ll need to checkout the sizes available.
Microcannula Sizes – Which Is the Best?
A variety of diameters, ranging from 18G to 33G according to the ISO 9626 standards, are accessible, with the 25 gauge cannula being the most versatile and common. The numbering also assists in determining the type of liquid that may get injected or sucked through the microcannula.
Denser substances may need cannulas that have larger internal calibers, indicating smaller gauge units. The varied sizes enable a securer and successful performance of numerous procedures. Its sizes may have encodings in various methods, whereby the dermatologist must be aware of readily.
The British system utilizes Birmingham wire gauge units, while the metric system uses millimeter units to determine the caliber. It is worth noting that cannulas with larger sizes may support relatively long shafts. The doctor should be capable of determining the cannula’s length through their empirical practice, keeping in mind both method and the region for treatment.
According to research;
- For fillers with low to medium viscosity and concentration uses 27G-30G microcannulas, being indicated for fine lines and nose.
- In the sensitive regions with small widths of the nasojugal fold, temporal area, and nose, 21G-25G cannulas are suitable using hyaluronic acid (HA) fillers with low to medium thickness and concentration.
- Microcannulas 21G-25G fillers of medium viscosity and concentration are satisfactory for most face applications.
- Now high viscosities and concentration fillers utilize microcannulas with 21G-18G.
The basis of aperture dimensions does not depend on specific wire width numerically but rather gets determined based on the sensitivity of the metal to draw a wire. The opening should be adequately small to reduce the diameter of the wire yet large enough to allow it to pass without breaking.
How a Blunt Cannula Works?
The injecting procedure for a blunt tip micro-cannula needle for fillers differs from a standard needle injection.
During a Microcannula filler injection, your doctor will initially access an incredibly tiny hole into your skin using a thin needle. The cannula filler tube is a hollow tube-like straw thinner than a coffee straw and causes minimal discomfort. Next, the doctor gently inserts the blunt tip micro-cannula needle for fillers via the tiny hole and directs it under the layer of skin to the injection targets. Cannulas provide greater insight to the injector upon insertion, letting them sense their way beneath the dermal layer with less effort.
The design of the tip is the most significant distinction that permits the microcannula to steal the spotlight. The needle method uses the bezel of the probe tip to pierce the outer layer of skin and the subcutaneous layers beneath.
Blunt cannulas eliminate this issue by pressing through instead of piercing. This essential modification to the injectable technique enables a competent injector to administer dermal filler without generating undue stress to you and reduces frequent adverse effects such as bruising, bleeding, or pigmentation. However, some common temporary side effects may occur, these are:
- Mild swelling
Nevertheless, to prevent any prolonged effects, you may apply ice to the treated area. Furthermore, avoid continuous vigorous massage as they can encourage the filler to break up more quickly.
Considering that several filler companies better by using microcannulas than sharp-tip needles. Hence physicians and aestheticians must comprehend the current cannula method accurately. It necessitates consulting a suitable, licensed, and trained doctor to expedite your treatment.
Consulting a reputable expert is among the fundamental aspects of getting the most out of your treatment. However, a certified medical doctor should be aware of the following factors:
- Avoid putting too much pressure on the blunt tip cannula
- Keeping in mind the rheology of your dermal filler
- The doctor must be well-versed in the equipment he employs
