Think Hush Gel, but spray. When applied properly and as needed, Hush tattoo-numbing spray anesthetizes the skin immediately on contact and lasts about 30-40 minutes once the skin has been broken, making the tattoo session virtually painless and worry-free.Hush’s proprietary blend of botanicals means less bruising and a faster healing time. And best of all, Hush Spray will not affect the tattoo color or design in any way.
