Blunt cannula

A blunt can­nu­la is a fine, fle­xi­ble hol­low need­le with a roun­ded tip and a side ope­ning. In aes­the­tic medi­ci­ne it is used as an alter­na­ti­ve to a sharp need­le, main­ly for injec­ting fillers.

Appli­ca­ti­on

Through a small ent­ry point made with a need­le, the can­nu­la is advan­ced beneath the skin and the pro­duct is dis­tri­bu­ted in a fan pat­tern. This allows a lar­ger area to be trea­ted through few ent­ry points. The tech­ni­que is popu­lar for the temp­les, cheeks, tear trough and jaw­li­ne when using der­mal fil­lers.

Good to know

The roun­ded tip tends to push blood ves­sels asi­de rather than pier­ce them. This lowers the risk of brui­sing and of vas­cu­lar occlu­si­on, but does not rule it out. For very pre­cise cor­rec­tions, such as the lip bor­der or deep pla­ce­ment on the bone, a need­le is often more sui­ta­ble. The right tech­ni­que depends on the area and the goal.
