Have you noticed that there are a lot of people that have Tattoos these days? In the past you may have only seen tattoos on people such as sailors, outlaws, and biker gangs but now tattoos are a very popular body decoration for many people. The types and styles of tattoos has also come a very long way. It is no longer crude pictures of pinup girls, skulls, and anchors. Tattoos have developed into very sophisticated art work ranging from Celtic crosses to very personalized symbols. People have found and created designs that express themselves in a very personal way.
Very simply a tattoo is a puncture wound made in the skin that is filled with ink. Although done differently today than in the past the technique is still somewhat similar. Today, tattoo artist use a tattoo gun that has one or more needles that penetrate the skin and delivery ink into the skin. Tattoos last a very long time due to the fact that the ink is placed deeply into the skin. The top layer of skins is called the epidermis and it is constantly shedding and being reproduced. If the ink from a tattoo was in this layer of skin it would not last very long. The layer of skin that the ink is injected to is called the dermis, which is a deeper layer of skin that is very stable and makes the tattoo stay visible almost permanently.
