I’ve always wondered about how tattoos actually work, and whether or not they really do hurt. When I see a particularly intricate tattoo piece, I always wonder how long it took, and how much it hurt.
The tattoo is actually injected in between layers of skin—that is what makes it permanent. When you write on your skin with a marker, it only goes on the epidermis, which is the very top layer of skin. This top layer of skin rejuvenates itself often, and you shed layers of dead skin—70-80 percent of dust is dead skin.
Different areas of your body are going to be more painful when you get a tattoo. Areas with less fat tend to be more painful: for example, the top of your foot, your inner forearm, your rib cage. These areas have little fat protecting the veins and muscles.
Since tattoos are put into your skin, they require aftercare that is very important to their healing. You should treat your fresh tattoo like an open wound, cleaning it gently with clean hands and keeping it dry.
