Some clients seeking the aesthetic benefits of dermal fillers are not aware of the reasons why many experienced doctors have begun to employ the use of blunt-tipped cannula’s alongside or instead of traditional needles.

To better understand why blunt-tipped cannula’s are preferred by some doctors and patients as well as to help decide which instrument you may favour it is worthwhile examining the benefits and drawbacks of each approach to depositing cosmetic fillers.

Similarities and Differences

Needles are a critical component of non-surgical aesthetic procedures. They are of the highest quality stainless steel and produced specifically to be exceptionally sharp. Those used in cosmetics are some of the smallest gauge medical needles manufactured.

Blunt-tip cannula’s appear nearly identical to needles with one distinct difference the tip is rounded instead of pointed.

 

Injecting dermal fillers in the past

In the past dermal fillers were inserted into the subcutaneous layer of skin tissue solely by the use of a traditional needle.

The sharp point of the needle was easily inserted after which the doctor ‘steered’ the needle to where filler was required. Once this location was reached, filler was injected through the hollow point of the needle.

While this was and remains an effective way to achieve the desired result it does have a drawback. Extremely sharp needles are completely undiscriminating when it comes to what they pierce. This means that often on their way to deposit filler they run into veins or small blood vessels which are accidently punctured which subsequently causes bruising.

Another way of injecting dermal fillers

Blunt-tip cannula’s are increasingly being used to do the job which needles did in the past. This is due to the benefits made possible by delivering fillers via a cannula. Whilst cannula’s do require an initial point made by a traditional needle to allow them entry into the subcutaneous skin layer, once they are inside there are some key differences.

Due to the unique rounded tips canula’s have they are unable to slice or penetrate skin structures on their own. This allows for less inadvertent trauma which is what distinguishes their use to that of needles.

Many doctors report that the use of cannula’s requires more concentration as it must be navigated around obstacles. Cannula’s then deliver the filler by ‘spooning’ it out via a small opening located on the side just above the cannula’s tip.

Why consider using cannula instead of a needle?

The use of blunt-tip cannula’s is considered to be more arduous and requires more skill than the use of a traditional needle.

Still many doctors including Dr. Martina van der Mescht feel that they are worth the extra effort for the following reasons:

  • Blunt-tip cannula’s can decrease the amount of damage in the delicate tissue layers of the hypodermis which subsequently results in less inflammation and fewer instances of bruising.
  • Blunt-tip cannula’s are generally longer than the average needle which allows more filler to be deposited from a single entry point which also works to minimize skin trauma.
  • Blunt-tip cannula’s offer a high level of control regarding where filler is deposited.
  • Blunt-tip cannula’s offer smooth and even results.
  • Blunt-tip cannula’s often show positive results quicker because less inflammation is incurred.
  • Blunt-tip cannula’s often reduce recovery & downtime because a less trauma is incurred.
  • Blunt-tip cannula’s can introduce collagen stimulation.

Client Choice of Comfort

Even with the potential positive benefits offered by using cannula’s some clients have reported that they prefer needles. This might be because if one is used to having procedures done with a needle, a cannula may feel disconcertingly unfamiliar.

Safety and the comfort of clients take priority and your personal preferences will influence the tools I select for a procedure. Whether you feel more at ease with a traditional needle or you favour a blunt-tip cannula, be assured that I have experience with both.

With a skilled doctor, either a needle or a blunt-tip cannula can be used to help create the aesthetic result you seek.
