The two needle technique for lip augmentation with Juvederm, how frequent is this?

The packages of juvederm fillers come with 2 needles. I often will use both because as you use a needle it dulls with each injection. Switching out to another needle lessens the pain of the injection. 

The use of several needles during injections is not uncommon.  In defining the lip border, often a very small needle will be beneficial to enhance the lip roll area.  If volume is desired in the body of the lip, a slightly larger needle may be used to allow more flow of material.  Additionally, a fresh needle, may be slightly less painful than one used on the adjacent area. 

Thanks for your question – and what you are describing is done all the time – many providers want their needles to be sharp for every part of the process and changing the needles is common for most of us.

Thank you for your question. Injectors often change
needles as they become less intensive while injecting over and again which is
absolutely safe and hygienic. There is nothing unusual to change needles and
cannula is to measure the correct amount of product into the targeted area. 

Your doctor may use more than one needle when injecting as the needle can get dull after a few punctures. Or they may use a cannula, which is a great technique I use to reduce bruising when injecting the lips.   Best wishes!

Thanks for the question! It is common and safe to change needles during injection. I often change needles multiple times to ensure that I have the smallest, sharpest needle. This allows me to minimize pain during the injection and produce the most accurate results.
Take care!

I sometimes change the needle when using the syringe around the mouth and going to different areas.  Each doctor is different.

Thank you for your question.  Not only is this safe, sanitary and acceptable, it is actually desired.  We frequently change needles, as they are so fine they dull very quickly.  Additionally, we often change between needle, cannula, and minis to get the exact right amount of product into the proper area.  Some of the top injectors in the world, like Dr. Arthur Swift or Dr. Kent Remington, literally change needles with every stick!  Regards, Dr. Matt Elias
