Do Local Anesthesia Shots to the Face Hurt Alot when Injected?

There are many ways to administer local anesthesia.  Some means are more comfortable than others.  I personally like to start by topically numbing the skin with anesthetic cream.  No matter what else, this take a big bite out of any discomfort.  For procedures like BOTOX and fillers, this is more than enough anesthesia for almost anyone.  Even lip edge treatment is pretty tolerable with the use of fillers like Restylane-L which contains the local anesthetic lidocaine.  For surgical type procedures in the office, I will use pH adjusted products like Septicaine which does not sting.  I also have a device called the Wand, which is a computer driven pump that administers local anesthetic much more slowly than humanly possible.  Using this combination of techniques, people are pleasantly surprised how comfortable the process can be.

Local anesthesia injected to the face can sting a bit from the acidic ph of the fluid. Someitmes this can be neutralized with bicarbonate. Also topical anesthetic can be used first before injection

There is some discomfort to receiving local injections. Every person has a different level of tolerance. some tricks that help are to buffer the solution which diminishes the burning feeling, use numbing cream before injection and have a regional nerve block. 

Everone has a different level of pain tolerance. Needles by defination hurt.. But, there are many tricks that can be used to make them tolerable.
