The CipherX patch replaces the conventional tattoo needle with microscopic structures made from biodegradable materials and tattoo pigment. There’s no home kit for now, and every Microdot Tattoo must be applied by trained CipherX staff at its London flagship or pop-up events. If you change your mind afterwards, the tattoo still needs to be removed with a laser or covered like any other permanent tattoo.
