UV tattoos that glow in the dark are becoming more and more popular. Do you want to know what effect it will have on your body? Let's first uncover the mystery of tattoo ink. It's not always easy to know exactly what's in tattoo ink. The main problem of identifying ink composition is related to some regulations, or rather, the lack of these regulations.

UV tattoos are made of ingredients that react when exposed to ultraviolet light. Some of these inks may contain phosphorus, which may be toxic, depending on the source or method of transportation. Those that don't may still contain plant ingredients, which can cause allergic reactions. The study found that UV tattoos have greater adverse reactions to the skin than traditional ink tattoos.
