If only an “invisible” colored ink is used, a black-light tattoo will blend with your skin color and barely be visible during daylight. For people who work in a conservative environment it’s a way of having a tattoo without irritating management. Ninja Ink is proud to offer UV Tattoos using KUROSUMI Glow, a leading vegan tattoo ink brand now manufactured in the US. But what is UV- Ultra Violet Light ? Is it safe? Here are some facts to answer your doubtful mind- What are UV Tattoos?A UV ink tattoo is generally invisible (or nearly invisible) under broad daylight. The ingredients of UV tattoo inks are slightly different from normal tattoo inks, because it has chemicals that react to Ultraviolet light (also known as "black light"). Hence, it is only visible under this special light condition. How do UV tattoos work?A UV tattoo becomes visible under blacklight, when it fluoresces in colors ranging from white to purple, depending upon the ink chosen. Colored inks are also available, where the ink is visible in normal light (as with a regular tattoo) and the ink will glow vividly under UV light. Is it safe?All tattoos come with their own risks and UV tattoos are no different. Making sure you go to a clean place with artists that know what they're doing is important to say the least. But what about the UV ink specifically? Do black light tattoos cause cancer?UV ink doesn't contain phosphorous, the carcinogenic ingredient that may cause cancer. However, glow in the dark tattoos, tattoos that only show in complete darkness but not in UV or black light, do contain phosphorous, according to

Black light tattoos are often confused with glow-in-the-dark tattoos. Unlike black light tattoos, glow-in-the-dark tattoos are only visible in the dark without any light sources. Black light tattoo ink purportedly has few side effects. However, tattoo ink is not completely free of side effects, especially if you have sensitive skin. The chemicals in UV ink are FDA-approved for animal usage, but they have not been cleared for humans. Since the FDA does not regulate tattoo ink, there is no proof whether it is truly safe.


Black light tattoos cost more than traditional tattoos, due to the time-consuming nature of the application. Another reason for the increased cost is the type of tattoo ink used. Seek a tattoo artist who is experienced in black light tattoos, as UV inks are more difficult to use, due to the fact that they apply more thinly than traditional inks. Someone who is inexperienced in this type of ink can easily make a mistake during the process or possibly cause an infection.
