DermaSculpt™ Micro-Cannula – Instead of the Needle

If there were a way to have your fillers injected with less pain and less bruising, how many would opt for that choice?

The choice is here now. Micro-cannula “injection” is the new way to deliver fillers. A micro-cannula slides under the skin for easier, more pain free and more bruise free placement of hyaluronic gels and Radiesse long term filler.

What is a micro-cannula?

A micro cannula is a very thin, tiny, flexible hollow tube with a smooth round tip. The sharp end is gone! Instead of many needle sticks, we only need a very few to provide entry points for the cannula. That means less needle marks, less pain and far less probability of bruising.


What are the benefits of a micro-cannula over a needle?

  • Reduced Pain
  • Less Bleeding
  • Less Bruising
  • Less Tissue Trauma or Swelling


Micro-cannula injection requires a single entry point for a large area instead of many as occurs with a traditional needle. Because the tip of the cannula is smooth and rounded, small vessels are simply pushed out of the way instead of being cut - so instead of pain you’ll most frequently experience little more than pressure.

How does the micro-cannula get into the skin?

An entry point is made with a traditional needle that is slightly larger than the microcannula. If desired, Dr. Fitzgerald will use a small amount of lidocaine to numb that area. Then the microcannula slides under the skin to the areas to be treated with filler.

How many entry points will I require?

For an upper and lower lip, only two – one at each end of the lip area. These same entry points can be utilized for filler in additional areas around the mouth and even into the lower cheek area. For a full lower face rejuvenation (cheeks, lip, mouth area, chin) you will likely have 4 points of entry.

The closed end of a cannula means a different delivery port.

Needles push the filler in front of the needle tip through an open end – Micro-cannulas have a small opening on the side and a closed end. This opening provides a smoother delivery of the filler so no matter what the pressure from the injector, there is a smoother flow of material.

Is a cannula now used for all injectables?

No. Sculptra and the toxins Dysport and Botox are still injected with a standard needle.

Really? No bruising?

No, you could still bruise. Anyone taking aspirin, ibuprofens, Vitamin E, fish oil or blood thinners still have a higher risk of bruising. (Anyone taking blood thinners are at extreme risk). But even with the existing potential for bruising, the incidence of bruising and the severity are dramatically reduced. Simply replacing the sharp tip for a round one makes a huge difference.
