Apply Prepcaine® to unbroken skin BEFORE tattooing, permanent makeup, electrolysis or other sensitive procedures. It is effective in numbing prior to all permanent makeup procedures and it reduces sensation on tattoo procedures performed on sensitive areas of skin. This handy to use bottle contains 2% lidocaine and 1.5% tetracaine in a cream base. Care should be taken to avoid getting any anesthetics into the eyes or mouth.
