It’s all about the particles in the tattoo ink’s pigment says Dr. Anne Laumann, MBChB, a professor of dermatology at Northwestern University.
Tattoo application uses a mechanized needle to puncture the skin and inject ink into the dermis or second layer of skin just below the epidermis. Since the process involves damaging the skin, the body responds with white blood cells which attempt to absorb the foreign particles and dispose of them in the blood stream.
“The reason pigment stays there is because the pigment particles are too big to be eaten by the white cells, so they just sit there,” Laumann says.
Tattoos have become increasingly popular in recent years. According to a 2010 Pew Research Report, approximately 40 percent of Americans between the ages of 18 and 29 have at least one tattoo.
The problem with tattoos is exactly what makes them so appealing—their permanency. “If you have the name of your boyfriend on there and then you marry somebody else, that’s a problem,” Laumann says.
Tattoos also tend to become problematic with age. Ink can become blurred if injected too deeply into the skin, causing the pigment to migrate beyond the intended area. Fading and distortion due to changes in body shape are also common problems with tattoos. Permanent makeup—or tattoos that resemble eyeliner or other makeup—is a prime example of how these problems can lead to dissatisfaction years after the ink is applied because skin sags and changes shape with age.
“The problem with that is as you get older the shape of the fold of the skin changes,” Laumann says. “So not only does it bleed a bit because the pigment moves gradually over time and so those will tend to become sort of smoky edges, but also the whole line might become a little distorted over the years.”
When a tattoo is no longer desirable, whether it’s faded or causing a bad case of buyer’s regret, you can burn it or cut it out—but the safest and most effective method is a laser treatment.
And that’s why I’m never getting one

A boy stopped as he reached a diverged road. In front of him lay two paths, to his left, and to his right. On the right he saw salvation. A chance to move on from the previous mistakes and wrongs he had made. It lay wide open as a chance for redemption and to diminish the distraught emotions he felt. So easy, would it be, to take that path. But to his left he saw a locked gate. Beyond it, the unknown. A mystery. Something he could not comprehend until he had it in within his grasp. An adventure. It offered no salvation, no redemption. Yet the closed doors concealed something the boy was curious about. He did not know what great things could be waiting on the other end. At this time the boy made his decision. He sat down. Right there, in front of the locked gate. He then waited. And waited. And waited. The boy had no idea when the gate would unlock and reveal its secrets to him. But still, he waited.
