Needle vs Cannula
Once upon a time in the Aesthetic World our main dermal filler tool was the trusty needle. Short, sharp, precise…what more could we need?
The downside to needles is that often multiple injections are needed and their sharp tip means that bruising can be a common side effect.

Along came cannulas, long, flexible and round-tipped, opening up a whole new range of techniques we could add to our skill-set.
Although a little scary-looking with their long length, cannulas are incredibly useful for areas such as cheeks, jawlines, tear troughs (in fact, almost every treatment area) as they can access a large area from just one entry point.
But by far, their best qualities are the blunt tip and bendy length - rather than penetrating through blood vessels, they tend to bypass them. So yes, that means less risk of bruising (and less risk of the rare but serious complication of injecting into a blood vessel).

There’s no one perfect tool, but the combination of needle and cannula have undoubtedly improved our techniques and safety when it comes to filler.
