Juvederm injection technique injecting filler as needle is going into the skin. Is this a common technique?

The technique of filler injection would depend on the type of filler and the depth within the skin or under the skin.Safety precautions include1: use of local anesthetic with epinephrine to make blood vessels vey small.2: Use cannula instead of needle to inject the filler3: inject as the cannula is drawn backThis will minimize the risk of intra-vascular injection, more control of the injection technique

Injection technique depends on the location, wrinkles/lines, and skill of the physician. Often we use different techniques for different things. There is what's called "fanning" which means the syringe is inserted and kind of wiggled in there like a fan while injecting, there's also bolus technique where small boluses of material are inserted, and then there's what you are talking about where the needle is inserted and the filler is injected as the needle is pulled out of the skin. This is what's often used for finer lines and wrinkles because it goes in smoother and finer."This answer has been solicited without seeing this patient and
