Needle vs Cannula

Needle vs Cannula

A needle is the traditional way of performing filler treatments. As you are aware from your foundation training it has a sharp tip and works with a high degree of accuracy.

A cannula is similar to a needle, but the tip is not sharp, it is blunt and rounded.  The cannula eye lift has a few benefits:

  1. Cannulas can be less likely to cause bruising after filler treatment
  1. Cannulas may be less painful than needles
  1. Cannulas may require less entry points because they tend to be longer than needles
  1. Cannulas may be safer than needles because it is less likely to puncture a blood vessel and inject filler where it doesn’t belong



How is cannula filler done?

The cannula delicately and precisely places a biocompatible material under the skin to lift the sunken area. Or to shape the jaw line

There are multiple dermal filler brands available (Restylane, Juvéderm, Restylane, Revolax, , Belotero, Volbella, Vollure, etc.), and these consist of gels that are packaged in a syringe or a tube.  At the tip of this tube is a cannula that delivers the gel in the right place.

Cannulas for the tear trough, and jaw lines improved safety and reduced risk of bruising.  Here in the UK, many patients want to be able to return to their busy lives with minimal recovery time.  The cannula can that much more likely than needle treatments for example tear trough treatment.

However, you don’t need to use cannulas for every filler treatment as certain situation are better suited for needle injections (e.g. shallow fine lines, acne scars, and surgical scars).
