black inkworkcancerinkquestionskintattattooblackuv ink January 29, 2011 at 3:58 pm #35725 Thanat0s24Guest @ If I were to get a tattoo in black ink, could i go over after it healed up with this UV reactive ink, without messing up the existing black ink? Or will this not work? Thanks for any help 🙂 January 29, 2011 at 4:25 pm #98188 ArniVidarModerator @arnividar I can’t find Sherav’s post right now to give you more details, but UV ink is toxic and has not been properly tested on humans. Don’t inject yourself with stuff you know nothing about and might end up giving you skin cancer or something. test sig Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to create new topics.
