Dangers of Topical Anesthetic for Laser Resurfacing?

dre
I have read that there are dangers in using topical numbing cream that can even be life threating if too much is absorbed in the blood stream. Can someone please explain this to me? If I am under the direct supervision of a Dr. I know my risks are greatly lessened, but can one still be prone to the dangers if administered correctly by a physician? Are the dangers based more on how your own body absorbs it or more by improper useage.
