Is Lidocaine Harmful to the Liver?

I have been told I am a good candidate for fractional co2. My only reservation is I have read that topical lidocaine is still absorbed into the blood stream and metabolized by the liver. I was diagnosed with hepatitis c three years ago, but have remained symptom free and have a normal liver count. Before I make the appointment I would just like to know if this already excludes me from the procedure? Thank you very much. Any information would be greatly appreciated.
