It seems like everyone has a tattoo these days. What used to be the property of sailors, outlaws, and biker gangs is now a popular body decoration for many people. And it's not just anchors, skulls, and battleships anymore — from school emblems to Celtic designs to personalized symbols, people have found many ways to express themselves with their tattoos. Maybe you've thought about getting one. But before you head down to the nearest tattoo shop and roll up your sleeve, there are a few things you need to know.So What Exactly Is a Tattoo?
A tattoo is a puncture wound, made deep in your skin, that's filled with ink. It's made by penetrating your skin with a needle and injecting ink into the area, usually creating some sort of design. What makes tattoos so long-lasting is they're so deep — the ink isn't injected into the epidermis (the top layer of skin that you continue to produce and shed throughout your lifetime). Instead, the ink is injected into the dermis, which is the second, deeper layer of skin. Dermis cells are very stable, so the tattoo is practically permanent.
