I Am Looking For A Topical Anesthetics Stronger Then Lidocaine

I am looking for a Topical Anesthetics stronger then Lidocaine 5% that I can on my under my eyebrows and upper lip. I am getting electrolysis done and she has to keep turning the setting down because of the pain I am feeling. The setting is so low that it is not effective. I can get my doctors to prescribe something if I know what to get.
