Tattooed skin should be cared for and treated just as regular skin in this regard. Depending on the type of adhesive used, it will hold as well over a tattoo as over un-tattooed skin. Vajazzling around tattooes can be a creative way to add sparkle to an already existing design on your body. It's not just limited to vajazzling. Glue Swarovski crystals in and around any of your tattoos.
