Which Micro Cannulas do you use for Dermal Fillers?

Why do I use Microcannulas?

Micro-cannulas are mini flexible versions of liposuction cannulas borrowed over from Plastic Surgery.  This could be a long discussion but the brief version of my reason is for: Safety and Results

  • Safety from injuring nerves.
  • Safety from injuring blood vessels.
  • Safety from injuring glands and ducts.
  • Better Results: I can get a smoother and wider fanning result.
  • Better Results: I can usually have less bruising with my patients.
  • Better Pain management:  Patients usually tell me that there is less pain with this technique.

Drawbacks to using blunt tipped micro-cannulas?

  • Sometimes it takes more time.
  • It is more costly for sure.
  • It is more complicated.
  • There is a definitely a technical learning curve.  I can say that I am much more adept at this now than compared to two years ago.

What are the differences between brands of micro-cannulas?

  • Price
  • Flexibility of the cannula
  • Location of the opening: some are closer to the tip and some are further back.
  • Packaging of introducer needles with the cannula – some come with the cannula, some come separately.  (Like batteries sold separately).
  • The presence of markings on the hub of the microcannula “needle” which shows the directionality of the opening at the tip.

What I use for micro cannulas

I have been using micro cannulas to inject dermal fillers for several years.  There are differences between the brands but I haven’t yet decided which ones I’d like the best.  I’ve used Magic Needle and Dermasculpt associated with CosmoFrance.  Right now I am mostly using Dermasculpt.  I have the 25G – 2 inch microcannula which I buy several hundreds of these at a time.  I’m starting to use this as my all purpose cannula for Cheeks, Tear Troughs, and Lips.  I have somehow found that this cannula is more comfortable for the patient and the 2 inch reach is very nice to have.  The other cannula I use from time to time is the 27G – 1.5 inch.  This is my usual cannula for tear troughs and for shorter lips.  But my thought process changes from time to time regarding which one I prefer.  I like the stiffness of the 25 gauge microcannula.  There are many options and I think one has to try several of these to see if they are worthwhile.  One should check often with their price policies too, as I got caught once with a surprise in their pricing of microcannulas because I was using an older order form.  I wasn’t too happy when I found out about the pricing / policy changes.  At that point I needed to tell them about a bent 25 guage 2 inch microcannula which I received in the past.  I have only received one bent (still in the package).  If I have time, I’ll post the picture of the bent one.  Regardless the cannulas are great, I don’t have a need for the directional marking of the side opening – that isn’t a feature that is currently useful for me.

I use Voluma, Juvederm, Radiesse and Belotero with all these cannulas.

I hope these ramblings about micro-cannulas for dermal fillers are helpful.  For me they have been a great addition to what I do with Botox and Fillers.  And I should add that I still inject directly with the sharp needles which are supplied in the dermal filler packaging.

Next, I probably need to probably write about a question a Botox trainee asked me recently:  “Which do you inject first, Botox or Filler, if it’s going to overlap in location?”  I have some thoughts on that.  Till next time
