Two guys from New York uni started their company, Ephemeral, to develop a tattoo ink that won't last forever!!
We could get all scientifically correct on this shit but let's not k, BASICALLY the dye 'molecules' in Ephemeral tattoo ink are small and located in a special capsule. With Ephemeral tattoos, all an artist has to do is retrace the ink with a tattoo gun filled with their special removal solution!!
