In the US, soft tissue fillers are currently administered using sharp, hypodermic needles. The choice in length and gauge of needle is determined by the injector's preferences, as well as the physical properties of the filler itself. While some adverse events are injector-dependent, others may be due to risks inherent to using sharp needles. The use of new, flexible cannulas with blunt tips may potentially both lower these risks and change the techniques by which fillers are administered in the future.
