What are Needles, Cannulas and Threads?

Cannulas: Cannulas are blunt-tipped metal cylinders with a side port that can be used in lieu of needles. The length and flexibility of these aesthetic cannulas allow cosmetic practitioners to cover a larger surface area with a single entry point.

Needles: A hollow, slender, sharply pointed instrument used for injection. Aesthetic needles are specially designed for dermal filler and toxin injection.

A thread lift is a type of procedure wherein temporary sutures are used to produce a subtle but visible “lift” in the skin. Instead of removing the patient’s loose facial skin surgically, the cosmetic surgeon simply suspends it by stitching up portions of it.
