What is the difference between a needle and a cannula?
The most obvious difference between a needle and a cannula is that the tip of a needle is sharp where as the tip of a cannula is blunt. The risk of VO is one of the main reasons practitioners prefer cannula in high risk areas as it won’t pierce blood vessel therefore less likely to cause complications.
Another major difference is that a cannula is generally longer than a needle and it’s more flexible. This means cannula allows for smoother and continuous delivery, perfect for jawline. A needle allows more control and accuracy especially in areas that require precision.
Ultimately there are benefits to both methods. A main factor in which to use is the area that is being treated and the client. It can also come down to personally preference Dr Laura will advise you on what is the best option for the area being treated.
