Numfast™ Green Cream is a Universal Topical Anesthetic with a pH of 7.6. It is unique because it stays put and won’t melt and run into the eye if applied on the eyelid(s). With an OTC strength of 2% Tetracaine it has a long lasting effect. Numfast™ Green comes in a hygienic ” no waste” squeeze tube that lets you apply exactly what you want and just where you want it. Both safe and effective, Numfast™ can be used after the skin is slightly abraded as well.
