Blunt Cannula for filler injection is a technique utilizing a blunt needle instead of a sharp needle to inject fillers, such as Juvederm, Restylane, Belotero, Voluma, Radiesse, Sculptra, Restylane Lyft, etc. The filler is still placed in the same locations; however, a blunt cannula is used to reach the areas needed to be treated.

The advantage? Blunt cannulas decrease bruising and swelling by over 90%. Of course, it doesn’t guarantee no bruising or swelling but the use of blunt cannulas has significantly decreased bruising and swelling rates. In fact, areas around the eye and lips that are common areas for bruising are easily injected with blunt cannulas without any visible signs of bruising or swelling. The blunt cannula filler injection technique allows patients to come in for injection and have a 9 out of 10 chance to go home or to dinner later that evening without any signs of an injection.

Why don’t all practitioners use blunt cannulas? It comes down to training and experience in the use of a blunt cannula. Also, cannulas are 50 times more expensive than a needle so only those with busy practices and a busy practice generally use it. Currently, less than a handful of injectors use a blunt cannula in Atlanta. Not all blunt cannulas are the same for blunt cannula filler injection. We use the Dermasculpt blunt cannula which is flexible, not rigid like many other less expensive and more painful cannulas.

It doesn’t take any longer to inject fillers with a blunt cannula as compared to a traditional needle. Blunt cannula filler injection has made some areas of the face safer to inject. For example, filler injection with a traditional needle was felt to be dangerous in between the brows, in the superior portion of the nasolabial folds, the nasal tip and nose, and tear trough region around the eyes. Now, however, we can easily and safely inject these areas without the constant concern of damaging the overlying skin or causing trauma to the eye increasing the use of fillers in these areas.

This treatment is performed in the office and is made more comfortable through the use of nitrous oxide (also known as ‘laughing gas’) to minimize any discomfort or anxiety, making your experience stress free. The patient can drive themselves home within 10 minutes of the treatment! Because of the analgesic properties of nitrous oxide, the treatment can be combined with others to maximize the patient’s time.
