Getting dermal fillers is a well-liked non-surgical skin treatment that improves the appearance of the face and cures a variety of skin issues, including wrinkles, fine lines, and volume loss.
The procedure is simple with little downtime, so it's not surprising that more people are using dermal fillers to keep their youthful appearance. But like other cosmetic procedures, the way they are administered matters a great deal to the result.
Aestheticians today employ either cannulas or needles in dermal fillers. But if you are looking for something new that may prove to be beneficial, then cannulas might be just what you need. Learn about how this new method is bringing the world of aesthetics closer towards what technology can offer.
So, is cannula injection the best for dermal fillers?
Let’s find out more!
Cannula Vs. Needles
A cannula is a thin, flexible tube ending in a blunt or rounded point that slides under the skin without inflicting harm or puncturing blood vessels. A sharp, pointed needle, on the other hand, makes it simpler to inject fillers into precise, targeted regions, but it also carries a higher risk of problems and bruises.
When weighing the benefits and drawbacks of cannula and needle injections, it's critical to acknowledge that certain patients may respond better to cannula injections than others, especially those with particular concerns or treatment objectives.
Needles, however, are still a practical and useful choice for a great number of people.
So, being aware of their distinctions will help you make an informed decision.
But before we dive deeper, how do practitioners use cannulas?
Cannula Injection for Different Facial Areas
Cannula injections are not that single use apparatus which can only be used in one specific area of the face, but are multipurpose instruments. Now let’s see how cannula injections perform better in various parts of the face.
Under-Eye Filler
The under-eye region is one of the thinnest layers of skin, which means that it is nearly impossible to needle, especially in the vicinity of blood vessels. This method has been used to reform the conventional treatments of under-eye issues since they are safer and more effective.
Lip Filler
Although cannula injections are becoming more and more popular for this area, needles are still often used for lip fillers. A cannula is better than a needle because it doesn’t make several entry points as is the case with a needle that leads to bruising and swelling. The result? Beautiful lips enhancement with less pain and swelling and fastest healing time.
Cheek Filler
The use of cannula injection works best to add volume on the cheeks. It gives you a contoured and lifted appearance that does not involve so much pain when you compare it to what is experienced if it was done through needle injection. Because the cannula can uniformly apply the filler it is perfect for creating bilateral, well defined cheekbones that look augmented naturally.
Then, you might be new to this world of aesthetics and wondering what even are dermal fillers?
Let’s recap;
What Are Dermal Fillers?
Dermal fillers are well-liked non-surgical substances that improve the appearance of the face and cure a variety of skin issues, including wrinkles, fine lines, and volume loss. They offer a customized approach to facial aesthetics by providing means of regenerating the skin. They can also solve a number of issues such as:
- Nasolabial folds: These are age and expression-related lines that naturally appear on the skin and are generally caused by aging, sun exposure, heredity, and the natural loss of facial fat. They can also become more noticeable with time.
- Marionette lines:These are vertical folds or lines around the mouth. As people age, they frequently become more noticeable because of a combination of gravity, volume loss, and loose skin.
- Cheek enhancement: Application of dermal fillers to restore the cheek volume in order to rejuvenate the face.
- Lip augmentation: A cosmetic operation intended to improve the appearance, contour, and fullness of the lips.
- Under-eye hollows: The depressed areas around the eyes may make it seem that there are some indentations, thereby giving the appearance of tiredness or even old age. Dark circles may attend these, especially when thinning of the skin or showing of the underlying blood vessels takes place.
Types of Dermal Fillers
They are:
- Hyaluronic Acid Fillers (HA): Very popularized for their water-attracting and binding qualities—it makes them seem 'plump' and hydrated.This group includes brands like Belotero, Restylane, and Juvederm.
- Calcium Hydroxylapatite Fillers (CaHA):These materials, which include Radiesse, are used to treat deeper creases and wrinkles. They increase the synthesis of collagen, which strengthens the structure.
- Poly-L-Lactic Acid Fillers: Fillers made of poly-L-lactic acid, such as Sculptra, restore volume gradually and durably by gradually boosting the body's production of collagen.
- Polymethyl Methacrylate Fillers (PMMA):Bellafill is a PMMA filler that offers support for soft tissues and forms a semi-permanent structure beneath the skin to produce long-lasting results.
How Are Dermal Fillers Injected?
They are administered through the following techniques:
Cannula Injection
A blunt-tipped, slender, flexible tube called a cannula is used to inject dermal fillers. The broad tip of the cannula, in contrast to the sharp end of a needle, enables it to pass through skin without puncturing blood vessels or incurring needless stress.
Pros of Cannula Injection:
- Decreased Risk of Bruising and Swelling:Because the blunt tip of the cannula makes it less likely to pierce blood vessels, there is a lower chance of bruising and swelling following the treatment.
- Lower danger of Nerve Damage:Cannulas reduce the danger of harming nerves by gliding over tissue as opposed to cutting through it.
- Shorter Recovery Time:Patients usually recover more quickly when there is minimal damage to the skin.
- More Natural-Looking Outcomes:Cannula injections make it possible for fillers to be distributed more evenly and smoothly, which frequently produces a more natural-looking appearance.
Cons of Cannula Injection:
- Not Suitable for All regions:Cannulas might not be the best choice for regions like fine lines or superficial wrinkles that require extremely accurate filler placement.
- Increased Cost: The cost of cannula itself as well as the specialist skills needed to administer the injection can make cannula treatments more costly.
Needle Injection
Injections have remained the traditional methods of administering dermal fillers. Because of their pointed tip, needles can accurately distribute filler to the desired area of the skin.
Benefits of Injecting Needles
- Precision:Needles provide more precise results, particularly when treating regions with fine lines or superficial wrinkles.
- Versatility: Needles are more adaptable than cannulas since they can be used in nearly any part of the face.
- Reduced Cost:In general, needle injections are frequently more cost-effective than cannula injections for lip augmentation and other cosmetic treatments.
Drawbacks of Injecting Needles:
- Increased Risk of Bruising and Swelling: Strickening blood vessels with needles increases the chance of bruises and swelling.
- Increased Risk of Nerve Damage:The needle's pointed tip may make it more likely that nerves will be harmed, particularly in places where they are more superficial.
- Longer Recovery Period: Patients may need more time to recuperate if they have sustained more skin trauma.
Why Choose Cannula Injection Over a Needle?
Are dermal fillers on your mind? Are you still curious if cannulas hold the key to a more youthful-looking, smoother complexion?
Though briefly discussed above, let's examine fully the benefits and drawbacks of this widely used injection method.
Benefits
1. Reduced Risk of Bruising and Swelling
The decreased chance of bruises and edema is among the biggest benefits of utilizing a cannula. The edge of the cannula is blunt which allows it not to penetrate blood vessel walls and this decreases the amount of pressure exerted on the skin and other cells.
Therefore, patients can use dermal fillers without being inconvenienced by the unappealing bruises that may sometimes be as a result of needle injections.
2. Enhanced Accuracy
By manipulating the cannula beneath the skin, medical professionals can access places that are hazardous or challenging to treat with a needle. As a result, the filler can be distributed more evenly and provide results that look more natural.
3. Reduced Chance of Problems
Cannula injections greatly reduce the likelihood of problems, such as vascular blockage. When a blood vessel becomes blocked, it can cause vascular occlusion, which, if left untreated, can result in tissue death.
The operation is safer since a blunt cannula is less likely to puncture a vessel. The cannula's blunt tip makes it possible for it to move around nerves without puncturing them, which is crucial in regions with higher concentrations of nerves, such the cheeks and under-eye circles. The safety profile of a cannula injection makes it a strong alternative to standard needles for both patients and practitioners.
4. Shorter Recovery Time
Recovery after a cannula injection often takes less time than that of a needle injection since there is less damage to the skin and tissues. Because patients may usually resume their regular activities more quickly, cannula injections are a suitable alternative for people who lead hectic lives.
5. More Natural-Looking Results
They especially aid in the areas where they mimic the look of a blemish, like the cheeks, and under-eye circles.
6. Evidence in Support
According to the National Library of Medicine,unlike needles, cannula injections minimize inflammation. In fact, there were fewer cases of inflammation in patients who underwent cannula injections as opposed to those who underwent needle injection.
Cannula Injections: The Cons
While you may have opted for cannula injections due to its numerous perks, they can have disadvantages. Though mild and rare, you need to comprehend them. They are:
Not Adequate for Every Face Area
Injectable cannulas might not be the ideal choice for every facial region. For instance, because a needle can accurately inject filler into the upper layers of the skin, it may be more effective in correcting fine lines or superficial wrinkles.
Increased Price
Cannula injections require a specialist procedure that is often more expensive. The procedure's complexity and the practitioner's level of experience can affect the price.
Supporting Evidence
Despite being usually well-regulated, cannula injections may not be appropriate for all parts of the face, according to certain research. While cannulas are great for deep injections, a research published on ResearchGate observed that they might not work as well for fine lines and superficial wrinkles.
Needle Injections: The Pros
They are:
1. Accuracy
Needles offer a high degree of precision, which is essential when treating regions like the tear troughs or small lines surrounding the lips that call for precise filler placement.
2. Adaptability
Needles are a flexible instrument for dermal filler injections since they can be used in almost any part of the face. Because of its adaptability, practitioners are able to customize care to meet the unique needs of each patient.
3. Reduced Price
For many individuals, needle injections are a more economical option than cannula injections because of their general lower cost.
4. Supporting Evidence
Numerous investigations have demonstrated the accuracy and potency of needle injections. For instance, according to information presented by Dr. Terrence Keaney during the January 14–17, 2021, ODAC Conference, discovered that needle injections were especially useful in reducing precise filler placement and produced positive patient outcomes.
Needle Injections: The Cons
Needle injections give certain benefits, yet as a flip side they have drawbacks as well, as you have a higher chance of developing swollen and blood clotted regions.
Bruising and Swelling
The dissection with the needle, owing to its sharp end, could injure blood vessels leading to bruising and swelling. This may lead to longer recovery times as well as side effects which are fairly evident.
Increased risk of Nerve injury
Sometimes, the use of needles might pose a threat to the nerves depending on the area of the body which bears these nerves. This is the reason for the occurrence of complications such as tingling or numbness in the treated area.
Extended Recuperation Period
Also, studies have shown that compared to cannula injections, it takes a patient longer to heal from needle injections given the risks of skin and tissue damages that are usually associated with the use of needles.
Supporting Evidence
Compared to patients who got cannula injections, patients who had needle injections exhibited greater bruising and swelling, according to a research published in the National Library of Medicine. Additionally, the study found that there was an increased risk of nerve damage from needle injections, especially in regions with more superficial nerves.
Choosing Between Cannula and Needle Injections
Here is how you should choose between a cannula or a needle for your cosmetic procedure:
1. The Area of Desired Treatment
The most effective technique depends largely on the region to be treated. A cannula may be a better choice for deep injections or locations where bruising is a concern while a needle might yield more exact results for wrinkles or fine lines.
2. The kind of dermal filler that is being applied
For volume restoration, for instance, thinner fillers for fine lines might be more suited for administration, whereas bigger fillers might be better suited for cannula injections.
3. The Health History of the Patient
Cannula injections may benefit patients with delicate skin or a history of bruising because they cause less trauma as compared to the use of needles.
4. Preferences of the Patient
The patient's comfort level and preferences should ultimately be considered. While some patients may value the accuracy of needle injections, others may prefer the less discomfort and faster recovery associated with cannula injections.
But, conventional needle injections can still be the best option if you're treating extremely fine lines or parts that need shallow filler placement.
