Our understanding of the aging process and how to best restore youthful features has evolved greatly over the past decade. This has resulted in more natural and rejuvenative treatments for patients.

The recent introduction of the DermaSculpt™ microcannula as a delivery system of dermal fillers is the latest innovation in non-surgical medical aesthetics. This revolutionary injection method allows for a safer and more comfortable experience for my patients.


Microcannulas are long, flexible, blunt-tipped and rounded instruments that are used as an alternative to typical needles when injecting dermal fillers like JUVÉDERM® or Restylane®.  Although the use of traditional sharp-tip needles is still required for certain injection areas, research indicates that injecting fillers using a microcannula provides several advantages over sharp-tip needles. These include:

  • practically pain-free injections
  • single injection site
  • significantly reduced bruising and bleeding
  • faster recovery and no down time
  • stimulation of collagen growth


Because the tip of the microcannula is blunt, the injection is less traumatic to the tissue. This reduces bruising and swelling, and allows for faster recovery from your treatment. Due to the length of the micro cannulas, typically one to two inches, fewer puncture sites are required to fill a longer fold or a wide area. In fact, I can inject an entire lip, a full nasolabial fold, an entire jowl and marionette area, or the back of your entire hand with a single puncture.


Other than feeling a slight prick as the microcannula is gently inserted, no other skin puncture is required. This translates into a much more comfortable treatment experience and no freezing is required. Most patients don’t even feel the cannula once it’s inserted. Patients are amazed to experience virtually pain-free injections.


Because the microcannula can reach a wide treatment area, procedure time is typically reduced. Additionally, because the microcannula is moved back and forth through the layers of underlying soft tissue as it deposits the filler precisely where it’s required, this technique stimulates collagen growth which, in turn, increases the long-term benefit of the treatment.


Another advantage of microcannulas is a significantly lowered risk of puncturing blood vessels, thus reducing bleeding and bruising. And since the filler comes out on top of the blunt tip and not through a sharp opening at its end (as is the case with a traditional sharp-tip needle), the use of microcannulas significantly lowers the risk of accidentally injecting fillers inside a vein or artery (intra-arterial injections). This virtually eliminates the risk of skin necrosis-an extremely rare but devastating risk associated with dermal filler injections.

This new technology is revolutionizing the way dermal fillers are injected and vastly improving patient’s overall experience. Microcannulas are quickly becoming the best practice among leading aesthetic medicine practitioners, and my patients are among those experiencing the many benefits of precise, virtually pain-free injections.
