There is a new ground breaking method to inject fillers into the face. Microcannulas are thin hollow tubes that are flexible with a blunted tip. This new technology significantly reduces pain and bruising since there is no sharp tip. Instead of multiple needle pricks there is one entry point. With the dull edge, bruising is minimized since there is not cutting of small capillaries. With the wide range of sizes, microcannulas can be used for fat transfers and fillers.
