You should know that a cannula is a flexible, long, round-tipped needle. It allows you to work not just one area but an entire face with just 2 or 3 stitches.
With this technique, theinjection is softer and much less traumatic than with a needle classic.
Indeed, the pain is essentially due to the passage of the needle through the skin. The round-tipped needles significantly improve comfort in the?injection, the patient only feels the very small initial puncture point through which the cannula is introduced, and in which I put a drop of anesthetic.
The cannula slides easily under the tissues to place thehyaluronic acid on the desired area for a natural result without hematoma. With this single point of entry, we can treat several areas.
The technique looks simple but it is only an air, it requires a perfect knowledge of the anatomy and a perfect analysis of the treated areas
