Dr. Weiner presents a paper recently published comparing the safety of injecting with cannulas versus needles. This was a survey among 370 dermatologist who primarily focus on filler injections. The conclusion from the paper is that cannula injections were 77% safer than needle injections of filler. There was slightly less long term sequelae when using cannulas as well. This supports Dr. Weiner’s long-term belief that cannulas are safer than needles. There are critiques of this study and those are included as well.
