When it comes to non-surgical facial rejuvenation, one of the most sought-after procedures is under-eye filler treatment. The delicate skin under the eyes often shows signs of aging, fatigue, and hollowness, leading many to seek a solution that can provide a refreshed, youthful appearance. While traditional needle-based injections are still widely used, the cannula technique has emerged as a safer and more precise alternative. In this guide, we’ll explore everything you need to know about cannula under eye fillers, including potential risks like over-filled under eye areas, the different cannula sizes used, and how to manage any lines that may appear after the treatment.

Over Filled Under Eye Filler

Cannula Under Eye Filler: Safe and Effective Treatments

One of the most common concerns when it comes to under-eye fillers is the risk of overfilling. Overfilled under-eye areas can create an unnatural, puffy appearance and can even cause discomfort. This is especially true for those with delicate skin or who are prone to swelling. While under-eye fillers are generally safe when performed correctly, several factors can contribute to over-filling:

Inexperienced Practitioner: One of the leading causes of overfilled under-eye areas is the lack of experience or expertise in performing the procedure. An unskilled injector may apply too much filler in the area, resulting in an overstuffed look. It’s crucial to choose a highly experienced specialist who understands the anatomy of the under-eye region and the importance of subtlety.
Incorrect Filler Placement: The under-eye region is a sensitive area with delicate skin, and it is critical to place filler precisely to avoid bulging or uneven distribution. Cannula under eye filler allows for more precision and control over the placement, reducing the risk of over-filling.
Use of Wrong Filler: Different types of fillers have varying viscosities and are better suited to different parts of the face. Some fillers are thicker and may not be ideal for the under-eye area, which requires a softer, more pliable substance for a natural look. If a thicker filler is used, the skin can become overfilled, causing visible lumps or puffiness.

Post-Treatment Swelling: After receiving an under-eye filler treatment, patients often experience temporary swelling, which can make the area appear overfilled for a few days. While this is normal, it’s essential to wait for the swelling to subside before determining if the results are satisfactory. In some cases, the filler may have been placed correctly, but swelling can cause temporary overfilling.
Overzealous Enhancement: Some patients desire a dramatic transformation, but subtlety is key in the under-eye area. Excess filler in an attempt to “over-correct” hollows or dark circles can lead to an overly youthful or exaggerated look, which doesn’t match the natural contours of the face.

How to Avoid Over Filled Under Eye Filler

Consult with a qualified injector: The best way to avoid over-filling is to choose a highly trained and experienced injector. Look for someone who uses a cannula technique for added precision and avoids excessive filler placement.
Choose the right filler: Make sure your injector uses a hyaluronic acid filler that is specifically designed for the under-eye area. These tend to be softer and more adaptable to the delicate skin in this region.
Go for a conservative approach: It’s better to under-fill than over-fill. A conservative approach can always be built upon in follow-up sessions, but if too much filler is placed, it may require a more involved procedure to correct.

Under Eye Filler Cannula Size

The size of the cannula used in under-eye filler treatments is a key factor that influences the outcome of the procedure. Cannulas are flexible, blunt-ended needles that allow for a more precise, controlled application of filler, which is essential for delicate areas such as the under-eye region. Choosing the right cannula size is critical to achieving natural-looking results without causing damage to the tissues underneath.

The Role of Cannula Size in Treatment: Cannulas come in different sizes, measured in gauge (G), which refers to the thickness of the needle. In the under-eye area, the choice of cannula size will depend on the amount of filler to be injected and the specific area being treated. Typically, a thinner cannula (around 25G or 27G) is used for under-eye filler to minimize trauma to the delicate skin and tissues under the eyes.
Why Smaller Cannulas Are Preferred for Under-Eye Filler: Smaller cannulas allow for more precise placement of the filler with minimal risk of bruising and swelling. They are flexible and allow for a gentle glide along the skin, preventing unnecessary damage to the surrounding tissues. Larger cannulas, though effective in other areas of the face, may cause more trauma and may be too thick for the delicate under-eye skin.

Choosing the Right Cannula Size: The choice of cannula size can also depend on the type of filler being used and the patient’s specific anatomy. A more experienced practitioner will assess these factors and choose a size that will provide the most natural-looking, long-lasting results. For example, a 27G cannula is often used for precise filler placement in the under-eye area, as it allows for smoother injection with less risk of complications.
Using Cannulas for Optimal Results: A key advantage of using a cannula over a traditional needle is that it causes less tissue damage and reduces the risk of complications like bruising. Cannulas are also ideal for treating larger areas of volume loss in the under-eye region, as they allow for even distribution without creating lumps or irregularities in the filler.

Benefits of Using a Smaller Cannula for Under-Eye Fillers

Less bruising and swelling: A smaller cannula reduces the chances of bruising and swelling, making the recovery process faster and more comfortable.
More natural results: Smaller cannulas allow for more precise placement of the filler, which means smoother, more natural-looking results that mimic the contours of the under-eye region.
Reduced risk of complications: Using a smaller, blunt-ended cannula reduces the risk of vascular damage and other complications that could arise from traditional needle injections.

Line Under Eye After Filler

While under-eye fillers can transform the appearance of your face by reducing hollowness and dark circles, some patients may experience the appearance of lines or creases shortly after the procedure. This can be a normal part of the healing process, but it can also be a sign of over-filling or other complications.

Common Causes of Lines After Filler: Lines under the eyes after filler treatment can occur due to a few reasons. The most common cause is the improper placement of filler. If too much filler is placed, or if the filler is not evenly distributed, lines may form where the filler has settled unevenly. In some cases, filler can migrate into fine lines or wrinkles, accentuating them rather than smoothing them out.

How to Prevent Lines After Filler: Choosing an experienced injector who uses the cannula technique can help prevent lines from forming. A skilled injector will be able to distribute the filler more evenly and ensure it stays in place, avoiding issues with migration and unevenness. Additionally, using the right filler that is suited for the under-eye area (typically a softer, more flexible hyaluronic acid filler) can also minimize the risk of lines.
How to Address Lines Post-Filler: If you notice lines appearing under the eyes after filler, don’t panic. Sometimes these lines are temporary and will resolve as swelling subsides. However, if the lines persist or worsen, a touch-up appointment may be necessary. A skilled injector can redistribute the filler or make slight adjustments to improve the overall appearance.

Proper Aftercare: Following the post-treatment instructions given by your injector can help prevent lines from forming or worsening after the procedure. This may include avoiding strenuous activity, minimizing direct sun exposure, and refraining from massaging or touching the treated area for a few days after the procedure.
When to Consider a Follow-Up Treatment: If lines under the eyes persist after a few weeks, it may be worth scheduling a follow-up appointment to assess if any adjustments need to be made. In some cases, the filler may have shifted or settled unevenly, requiring a small touch-up to correct the issue.

Final Thoughts

Cannula under eye fillers are a safe and effective way to address volume loss, dark circles, and hollow areas under the eyes. With the right technique, they provide smoother, more natural-looking results with reduced risks of bruising and swelling. However, achieving the best possible outcome requires the expertise of a skilled injector who understands the delicate anatomy of the under-eye region and can prevent common issues like over-filling, lines, and improper filler placement.

If you’re considering under-eye fillers, make sure to do your research and choose a qualified provider. Don’t rush into treatment; a conservative approach with a focus on subtlety will yield the most beautiful, youthful results without the need for frequent touch-ups or corrections.
