How do you inject filler in a microcannula?
Inject filler in a retrograde fashion. Start injecting while pulling the length of the microcannula in and out of the skin. To change direction, pull the cannula out of the skin almost entirely, back to step two (leaving the tip at the desired depth). tip: You can fan the area 360 degrees around the hole.
What’s the difference between a cannula and a needle?
A cannula in this context is a blunt-tipped, hollow tube that functions as an alternative to a needle when administering dermal fillers. Dermal fillers (such as those sold under the Juvéderm brand name) have traditionally been administered using sharp-tipped needles.
