What is a Lip Filler Cannula?

A lip filler cannula is a thin, blunt, flexible tube used to inject dermal filler products like Juvederm or Restylane into the lips. It offers an alternative to traditional sharp needles for lip injections.

Some key benefits of lip filler cannulas include:

  • Allow smooth, controlled injection of filler with less damage to surrounding tissues than needles
  • Require only 1-2 entry points to fill the entire lip area
  • Reduce risk of lumps, bumps and irregularities compared to needle injection
  • Result in less swelling, bruising and discomfort during and after treatment

With a cannula, Dr. D’Alessio can sculpt beautiful lip definition and shape by fanning the filler evenly across each lip quadrant. This is why cannulas have become a top choice for achieving soft, natural-looking lip enhancement.

How Does Lip Filler with a Cannula Work?

Using a cannula for lip filler is a technique that allows precise placement of dermal filler with minimal discomfort. Here is a more in-depth look at how it works:


  • Dr. D’Alessio will first cleanse and numb the lip area with a topical anesthetic cream. This helps make the treatment more comfortable.
  • Next, they map out planned injection points by making small marks at the oral commissures (corners of the mouth). This provides guidelines for the cannula entry location.

Cannula Insertion

  • A needle is used to create tiny access points at the marked oral commissure sites. The needle is then removed.
  • The flexible, blunt-tipped cannula is lubricated and carefully inserted through these access points to enter the lip tissue plane.
  • The cannula is slowly guided through the lip while she injects microdroplets of dermal filler precisely into the submucosal layer. This is the deepest layer of the lips.
  • The cannula tip remains under the lip tissue, moving smoothly to fill the entire lip area. This allows wide distribution of filler with minimal injections.

Final Steps

  • Once the desired filler correction is achieved, the cannula is withdrawn through the access points.
  • Dr. D’Alessio cleans the skin and applies a soothing cream to the access sites. A cold pack can further reduce swelling and tenderness.

The cannula technique requires an expert injector with advanced skills in lip anatomy. Precisely tunneling the cannula beneath the lip tissues allows accurate placement of filler in the deepest lip layers. 

Results are smooth and even with a natural look and feel. Utilizing a cannula for dermal fillers takes lip injections to an advanced level.

Benefits of Using a Cannula for Lip Fillers

Cannulas offer important advantages over traditional needles for lip augmentation including:

Less Pain and Discomfort

The blunt cannula tip glides smoothly through tissues. This minimizes the needle pricks from multiple sharp needle injections into ultra-sensitive lip tissues. Patients report significantly improved comfort compared to needle lip fillers.

Minimized Bruising and Swelling

The cannula technique requires fewer entry points and causes less trauma to blood vessels. This results in noticeably less bruising, swelling, and downtime than needle-injected lip fillers.

Lower Risk of Vascular Complications

Penetrating a blood vessel with an injection needle carries risks of vascular occlusion, ischemia and even skin necrosis in rare cases. Studies show cannulas reduce the chances of these dangerous vascular complications.

More Precise Placement of Filler

The cannula’s flexibility and blunt tip provide great control over filler placement. Dr. D’Alessio can precisely shape and define lip contours for very natural-looking, even augmentation.

Single-Entry Point Technique

Entire lip enhancement is achieved through just 1-2 small access sites with a cannula. This lowers risks of bruising and asymmetry and creates a more uniform result.

Higher Volume Capacity

Cannulas can comfortably deliver larger amounts of filler in a single session since material is continuously injected through the same entry sites.

Difference Between Lip Fillers Using a Cannula vs Needle

While both are effective, cannulas and needles differ in some important ways:

TipFlexible blunt tipRigid sharp needle tip
Injection techniqueAllow filler to be slowly layered for precise shapingGive more localized injections
Entry pointsSingle cannula entry points reduce risks of bleeding and asymmetryMultiple needle punctures increase risks of bleeding and asymmetry
Vascular complicationsShow lower rates of vascular complications like occlusion according to researchCan potentially have higher rates of vascular complications
Filler migrationCan potentially have more filler migration along cannula pathMinimize filler migration along needle path

The tool chosen depends on the goals, anatomy, injector preference and type of filler used. Many providers artfully combine cannulas and needles to optimize results.

Are There Any Risks With Cannula Lip Fillers?

While considered extremely safe, a few potential risks associated with cannula lip fillers include:

  • Overfilling results in unnatural duck lip appearance if too much filler is used.
  • Bruising, swelling, lumpiness, which normally resolve over days.
  • Numbness, tingling or redness, typically lasting a week or less.
  • Infection risk from non-sterile technique (rare).
  • Allergic reaction to injectable filler components (uncommon).
  • Vascular compromise and ischemia is possible but very low risk with cannulas.

An experienced board-certified provider like Dr. Donna D’Alessio at Montville MedSpa will take every precaution for your safety and beautiful results.

How Long Do Lip Fillers By Cannula Last?

When lip fillers are injected using a cannula technique, they typically last longer compared to a traditional needle injection. This is because the cannula causes less trauma to the tissue during injection. Here is an overview of how long different dermal filler types injected by cannula may last in the lips:

  • Hyaluronic Acid Fillers: 6-12 months. This includes popular fillers like Juvederm, Restylane, and Versa. The lips have a high turnover of hyaluronic acid, so these fillers tend to break down faster than other areas. Most patients need touch-ups around 6-9 months to maintain lip fullness.
  • Calcium Hydroxylapatite: 12-18 months. Radiesse is the main filler in this category. It stimulates collagen production for longer-lasting effects. Lips injected with calcium hydroxylapatite fillers can often last up to 18 months before a touch-up is needed.
  • Poly-L-Lactic Acid: 18-24 months. Sculptra is the most well-known PLLA filler. It provides a very gradual volumizing effect as it stimulates collagen over time. In the lips, PLLA fillers may last 18-24 months due to the stimulating effects on collagen.

The longevity depends on several factors:

Filler typeThe composition of the filler determines how quickly it will be broken down and absorbed by the body. More robust fillers like Radiesse and Sculptra tend to last longer.
Injection amountMore filler equals longer lasting results. Though keep in mind the “just right” amount should be injected to fit your facial proportions.
MetabolismPeople with faster metabolisms tend to break down fillers quicker than those with slower metabolisms. This means you may be on the shorter or longer end of the duration spectrum.
Lip movementThe constant motion of our lips through eating, drinking, talking etc. can contribute to faster breakdown of the fillers compared to less mobile areas.

Keep in mind dermal fillers are not permanent, and your body will gradually absorb the filler over time. Maintenance appointments for touch-ups every 6-24 months (depending on filler type) can help sustain your refreshed, voluminous lip look. 

Be sure to schedule check-ins with Dr. D’Alessio to evaluate if and when you may need more filler for upkeep.
