Cannula Method for Injecting Dermal Fillers

EXTON, Pa. - March 27, 2015 - PRLog -- Chances are, if you've had dermal filler injections, you didn't give much thought to the injection technique used by the physician. More and more, physicians are discovering the benefit of using a cannula method for dermal filler. Patients experience less bruising, swelling, and fewer injection points.

Unlike a needle, a cannula has a blunt, rounded tip that allows for more control to avoid damaging a blood vessel, vein, or artery reducing chances of swelling or developing a bruise. A needle, with a sharp tip, will pierce its way through skin and tissue to get to the injection area.

With its blunt tip, a cannula cannot pierce the skin initially. A small needle hole has to be made in order to insert the cannula. Because the cannula is much longer than most needles, a larger facial area can be treated with one injected rather than multiple needle injections for the same result. Not only do cannulas reduce the risk of bruising and swelling, but some patients also experience less pain.

The cannula technique is often the preferred method for the cheeks, and infraorbital area (undereyes). Ultimately, the cannula method touts several benefits and can be a much safer way to inject dermal fillers.
