What is a good numbing cream for tattoos and should you use one?

I found a good numbing cream for my tattooing sessions. The one I used helped. I found it to be effective and safe. Now I'm not worried about the pain in my tattoo sessions. I became confident about going at the tattoo shop. The numbing cream I contains 5% lidocaine the highest amount allowed by food and drug administration. It is a water-based numbing cream. Whatever numbing cream you might use, choose one that is medically tested.
