Blunt Tipped Microcannulas for Dermal Fillers (Restylane, Juvederm, Radiesse, Perlane) is "The Bomb"

About 2 years ago, I had one of those “AHA” moments when I saw a physician from France demonstrate the use of blunt cannulas for injecting dermal fillers.  Since then, I have hardly used the traditional needle method for fillers and my patients love it.  I have become one of the strongest advocates of this technique, and it has revolutionized my thoughts about fillers.

Blunt cannulas have a rounded tip and are very flexible.  The advantages are:

  • The bruising and swelling post procedure are dramatically reduced.  So you don’t have the social downtime after having your lips done (which can be up to 2 weeks).  Blood vessels bounce off the tip and are not injured as easily with the cannulas.
  • Procedural discomfort is much improved in most areas.
  • With only 2 entrance “pokes”, I can enhance the lips, vs. at least 10 pokes using needles.
  • Overall time of procedures are significantly reduced.  Because I’m not using topical anesthesia in most cases, the total time to have your smile lines injected can be only a few minutes.  Under eye injections are the same.  In and out of the office more quickly and then go to lunch.
  • The risk of a vascular catastrophe is almost eliminated because you can’t enter a vessel with a blunt cannula.  You can still compress a vessel, but this is a much easier problem to deal with than an intravascular injection.  So BLUNT CANNULAS ARE A MUCH SAFER WAY TO INJECT DERMAL FILLERS.
  • I can inject the upper lip lines, lips, nasolabial folds, marrionette lines, and lower cheek, all through the same entrance site.
  • Tear trough injections can be done deep to the muscle to avoid the filler from showing (“Tindel Effect”)

 

I can use the cannulas for all fillers except Sculptra

 

 

The only area which I might use a needle to inject filler now is along the vermilion border of the lips and for superficial fine lines or scars.

 

When choosing a physician for filler, technique makes a world of difference…ask my patients.
