1- Find a tattoo artist who has single-use, “throw-away” kits that are individually packaged, dated, and sealed and hold disposable needles and tubes. Watch your tattoo artist remove the new needle and tube from its sealed envelope immediately before your session. 2- Make sure that the tattoo parlor is fully licensed , and that your tattooist has a great deal of experience, even if that means driving across county lines to find a licensed shop. 3- Make sure the artist wears sterile disposable gloves for each client and use sterile disposable towels, much as you’d expect from your dentist. 4- Watch a procedure first to make sure that unsterile surfaces and equipment are not touched by the tattoo artist once the procedure has begun. 5- Look for telltale signs of sloppy tattoo practices, such as blood splatter, dirty work surfaces, the absence of red “sharps disposal containers,” and a lack of infection-control practices. 6- Ask where the ink was manufactured and procured , It is better to use ink manufactured by big companies. 7- Ask if the inks used are made of nonmetallic organic pigments. 8- Consult a doctor if you see any sign of rash or infection (redness, swelling, or drainage of pus).
