what a great question. it depends on where the tattoo is located on your body, of course. you’ llwant to avoid scratching or bumping the tattoo, or letting clothing (or bedsheets) rub against it excessively. also, don’t let sweet, saliva, or other bodily fluids sink in.
a tattoo is a wound and needs to be treated like a wound, keep it clean, keep it dry, but also keep it moisturized with a dye-free, fragance-free lotion.
