Detailed explanation-1: -When you get pierced with a needle, each needle is single-use, so you don’t risk getting someone else’s blood or bacteria in your piercing. Other piercing instruments are made of metal and sterilized using high-pressure steam in an autoclave so you can rest assured that everything is safe and clean.

Detailed explanation-2: -Medical ear piercing uses surgically sterile techniques to eliminate contamination. They use single-use disposable cartridges to pierce and insert the posts simultaneously. Be sure to use studs and earrings that don’t contain nickel, so there is no possibility of an allergic reaction.

Detailed explanation-3: -If you must reuse a needle, sterilization can be tried at home, but will never provide a complete, 100 percent guarantee. New needles come packed in sterilized packaging. They cease to be completely sterile once they hit the air, and should be used as quickly as possible after unwrapping.
