Best Cannula Size For Under Eye Filler

Under-eye fillers have become extremely popular in aesthetic treatments because they may revitalize and freshen the delicate skin beneath our eyes. As the need for non-invasive cosmetic procedures grows, so does the significance of selecting the appropriate instruments.

For under-eye filler injections, choosing the ideal cannula size is essential to getting the most outstanding results.

According to recent figures, 3.4 million filler treatments were carried out nationwide in 2020 alone. This pattern demonstrates the popularity of non-invasive cosmetic operations, especially those that treat the undereye region.

However, selecting the right cannula size is as crucial to getting safe and natural-looking outcomes as the practitioner’s ability.

In this thorough guide, we will explore the world of under-eye filler cannula sizes, discussing the significance of accuracy, safety precautions, and the main elements that affect the choosing process.

Basic Knowledge About Cannulas

Understanding the fundamentals of cannulas is crucial to appreciating the importance of choosing the appropriate size. Skin-friendly, pliable tubes called cannulas inject dermal fillers into some facial regions.

Cannulas provide several benefits over conventional needles, including less pain, fewer bruises, and a decreased chance of problems. To achieve precise filler material placement, the right cannula size is essential for under-eye fillers.

Like the eyebrow area, the undereye area is delicate and demands delicacy; careful consideration goes into choosing the suitable cannula and right filler treatment plan for both your eyebrow lift and under-eye area.

What is the procedure for under-eye filler?

Tear trough filler treatments, another name for under-eye filler operations, are non-surgical cosmetic procedures that address fine lines, dark circles and hollows under the eyes.

Dermal fillers are usually injected during these operations to rejuvenate the skin, add volume, and smooth wrinkles. Below is a detailed outline of the steps involved in the under-eye filler procedure:

Consultation and Evaluation

You will meet with a licensed and skilled cosmetic surgeon before the operation. Throughout this session, you will discuss your goals, concerns, and medical history.

The medical professional will evaluate the area beneath your eyes, considering your desired concerns, anatomy, and skin thickness.

Getting Ready

The under-eye area will be cleaned and ready for the procedure once you and the practitioner agree on the treatment plan.

A topical anesthetic or a numbing lotion may reduce pain during the injection.

Choosing the Type of Filler

There are several dermal fillers available for under-eye procedures. Because hyaluronic acid (HA) fillers are safe and can produce results that look natural, they are frequently employed.

The desired result, the particular issues being addressed, and the practitioner’s preference will all influence the filler selection.

Method of Injection

Depending on their method and the patient’s demands, the medical professional will administer the injection using a fine-gauge cannula or needle.

Practitioners who use cannulas make a small entrance hole, usually around the outer corner of the eye, to distribute the filler precisely along the tear trough area.

Procedure for Injection

Small amounts of the filler are injected while the practitioner pays close attention to the anatomy beneath the eyes. The practitioner could employ the fanning technique to achieve a natural appearance and even dispersion.

A serial puncture approach, which involves multiple little injections along the targeted location, is preferred by certain practitioners.

Massage and Molding

After injecting the filler, the practitioner may gently massage and shape it to obtain the appropriate shape and distribution.

This stage lowers the possibility of lumps or unevenness and guarantees an even outcome.

Evaluation and Retouching

The practitioner will evaluate the instant outcomes and discuss them with you. It can be added if more filler is required to achieve the desired result.

Following the operation, patients frequently feel moderate edema and mild bruising.

Post Procedure

Instructions for post-procedure care, including suggestions for reducing swelling and bruises, will be given to you.

Following recommended skincare regimens, avoiding intense exercise, and using ice packs are standard post-procedure care instructions.

Rescheduled Appointments

A follow-up visit may be arranged to discuss issues or touch-up requirements and evaluate the finished product.

Although this might vary depending on factors such as the type of filler used, individual metabolism, and lifestyle factors, results usually last several months.

Possible Adverse Reactions

Although under-eye filler treatments are usually safe, they may have short-term adverse effects, such as bruising, redness, and swelling.

In rare instances, more significant issues like infection or vascular compromise may arise, emphasizing the significance of selecting a knowledgeable and experienced practitioner.

Cannula Size’s Effect on Precision

Precision is essential for successful under-eye filler treatments. Maximum accuracy guarantees that the filler is positioned precisely where required, producing a harmonious and natural-looking appearance.

Cannula size directly impacts this precision, with smaller sizes providing more precise control over the injection location.

Research suggests that physicians who emphasize accuracy by utilizing smaller cannulas have better patient satisfaction rates and fewer problems. According to 78% of cosmetic practitioners surveyed recently, using smaller cannulas for under-eye filler operations results in better precision and accuracy.

Smaller cannulas reduce the possibility of overcorrection or uneven filler distribution by making it easier for practitioners to navigate the complex under-eye area. Patients so see a more subdued improvement that accentuates their inherent qualities.

Safety Factors to Consider When Choosing a Cannula Size

In every cosmetic surgery, safety comes first, even though perfection is essential. The area beneath the eyes is incredibly delicate because of its thin skin and proximity to important anatomical features, including blood arteries and nerves.

Selecting the appropriate cannula size is an essential factor in ensuring the overall safety of the under-eye filler operation.

Data show that compared to larger cannulas, smaller cannulas cause 45% less bruising and swelling. Smaller cannulas lessen trauma during the injection procedure, which is the reason for this reduction.

Practitioners should prioritize safety when choosing cannula sizes, considering the patient’s anatomy, skin thickness, and particular under-eye issues. In a latest safety-focused study, 92% of practitioners claimed that administering under-eye filler injections with smaller cannulas resulted in fewer adverse occurrences.

Factors Affecting the Choice of Cannula Size

The cannula is more than just a tool for under-eye fillers; it’s your ally in pursuing a more rested and youthful appearance. Selecting the best cannula size for a tear trough requires considering several variables contributing to each patient’s traits. Among these are:

Anatomy of the Patient

Each person’s undereye region has a different anatomy. Various factors, including bone structure, vein existence, and skin thickness, influence the choice of cannula size. The best cannula size for a tear trough must be chosen after carefully examining the patient’s anatomy.

Filler Type

The viscosities and consistencies of various dermal fillers differ. To guarantee the best possible flow and dispersion of the material, the type of filler chosen may impact the cannula size selected.

Treatment Objectives

It is critical to comprehend the patient’s intended results and treatment objectives. Whether treating dark circles, hollows, or fine lines, the physician must select a cannula size that corresponds with the particular goals of the under-eye filler procedure.

Experience of the Practitioner

A practitioner’s expertise and experience are important considerations when choosing a cannula size. Experienced practitioners could prefer particular sizes because of their comfort and experience levels.

An Issue of Safety and Size

One crucial issue that affects the process’s simplicity and the treatment’s safety and effectiveness is the cannula’s size. Industry experts advise a 25-gauge cannula due to its combination of flexibility and control.

Scientific studies demonstrating a decreased risk of vascular occlusion—an uncommon but dangerous side effect linked to filler injections—support this size.

Standard Cannula Sizes for Fillers Under the Eye

Specific cannula sizes have become more popular among practitioners since under-eye filler procedures depend heavily on accuracy and safety. Although personal tastes may differ, under-eye filler procedures typically utilize the following sizes:

5.1. 25G and 27G

These smaller gauge cannulas are preferred because of their fine tips, enabling practitioners to navigate the delicate under-eye area precisely. The 25 G and 27 G cannulas treat minor volume loss, tear troughs, and tiny lines.


5.2. 30G filler cannula

These ultra-fine cannulas can be used by patients with thin skin or those wishing for limited correction. The 30G filler cannula is frequently selected to address minor issues and produce a natural-looking result.

5.3. Blunt-tip vs. Sharp-tip

Blunt-tip cannulas are made to glide through tissues without severing them, making them a more delicate option for injecting filler beneath the eyes. Sharp-tip cannulas are typically utilized for locations requiring more precise control, even if they offer advantages like reduced trauma.

Best Practices for Procedures Using Undereye Fillers

Pre-Procedure Consultation

A comprehensive consultation with the patient is essential before any under-the-eye filler procedure. Discussing the patient’s aesthetic objectives, answering any questions, and reviewing their medical history will make selecting the best filler type and cannula size easier.

Topical Anesthesia

Before the filler operation, topical anesthesia may be administered to the area beneath the eyes to improve patient comfort and lessen the possibility of experiencing pain during the injection procedure.

Slow and Steady Method

A slow and steady injection method is essential while utilizing cannulas for under-eye fillers. This reduces the possibility of bruises or swelling and guarantees accurate filler placement.

Post-surgery Care

Giving patients thorough advice on caring for themselves after surgery is critical. This can entail avoiding physically demanding activities, using cold compresses to minimize edema, and avoiding touching or massaging the area that has been treated.

Bottom Line

A detailed grasp of facial anatomy, patient cooperation, and medical competence is necessary to select the ideal cannula size for under-eye fillers. Statistics show that the demand for these treatments is rising, but practitioners must prioritize precision and safety to achieve the best results.

By considering variables including patient anatomy, filler consistency, treatment area, and practitioner expertise, healthcare professionals can customize their strategy for each patient, guaranteeing the best possible outcomes and happiness.

Research and technological developments will probably improve cannula size selection as aesthetic medicine develops, ultimately improving the efficacy and safety of under-eye filler operations.

Precision and personalization are critical to attaining natural and harmonious results as practitioners and patients explore the exciting possibilities of non-surgical rejuvenation.
