    There are UV reactive tattoo inks. Not exactly the same but pretty close, and probably safer than trying to manipulate your genes.

      They had a whole sets of beauty products based on radium in the 20’s of the past century. They had several peculiarities such as natural luminescence and a unique pale white colour that used to shine in the darkness. I needn’t to say that this was obviously one of the most dangerous and damaging things you could apply to your body. tho-radia was a body lotion and a brand that took pride in using radium in many ways, including a product for teeth. Radioactive teeth, imagine that. I hope you don’t come across one of those old bottles in an antique shop, as they are still dangerous.

        UV tattoo ink is one of the only inks that have been approved by the FDA (for animal use). They’ve been used for a long time in livestock. Not that that should make you comfortable with sticking it into your skin or anything, but it’s probably not quite the same as powdering your face with radium.

        While we’re on the subject of historically misguided applications of radioactive materials: ever heard of uranium glass? People get real weird around spicy rocks.
