Sustaine® 
This  topical anesthetic contains 4% lidocaine and 2% tetracaine for numbing, as well as .02% epinephrine to reduce the swelling, bruising and bleeding.  
Sustaine's speed and effectiveness in reducing bruising and swelling make it popular for sensitive work such as inner armbands, eyeliners, and the inflammation often associated with other sensitive areas.  
We do not recommend re-applying this product more than twice in one sitting, in the same area.  
Care should be taken to avoid getting any anesthetics into the eyes or mouth.
