Although laser treatment is well known and often used to remove tattoos, unwanted side effects of laser tattoo removal include the possibility of discoloration of the skin such as hypopigmentation (white spots, more common in darker skin) and hyperpigmentation (dark spots) as well as textural changes - these changes are usually not permanent when the Nd:YAG is used but it is much more likely with the use of the 755 nm Alexandrite, the 694 nm Ruby and the R20 method. Very rarely, burns may result in scarring but this usually only occurs when patients don't care for the treated area properly. Occasionally, "paradoxical darkening" of a tattoo may occur, when a treated tattoo becomes darker instead of lighter. This occurs most often with white ink, flesh tones, pink, and cosmetic make-up tattoos.
Laser tattoo removal is a successful application of the theory of selective photothermolysis (SPTL). However, unlike treatments for blood vessels or hair the mechanism required to shatter tattoo particles uses the photomechanical effect. In this situation the energy is absorbed by the ink particles in a very short time, typically nanoseconds. The surface temperature of the ink particles can rise to thousands of degrees but this energy profile rapidly collapses into a shock wave. This shock wave then propagates throughout the local tissue (the dermis) causing brittle structures to fragment. Hence tissues are largely unaffected since they simply vibrate as the shock wave passes. For laser tattoo removal the selective destruction of tattoo pigments depends on four factors:
“The big misconception with tattoo removal is that it’s an eraser,” Sherrif F. Ibrahim, M.D.,, an associate professor in the department of dermatology at the University of Rochester, tells SELF. But it’s not that simple. “It’s a process,” he says. Sometimes, complete removal of a tattoo can take one or two years, with treatments occurring every 6, 8, or 12 weeks. Plus, it’s not like getting your eyebrows waxed—it’s an invasive procedure that costs hundreds of dollars a session. Lasers remove tattoos by blowing up pigment molecules into tiny pieces, which are then cleared away by an immune system response. Healing from laser treatment isn’t always a walk in the park, either. “The laser breaks the skin’s surface, so you have bleeding, you have swelling, and you have pain after the treatment,” says Dr. Ibrahim.
The answers to those questions will determine whether you’re looking for a design or a specific image. A lot of guys are going for floral, geometric, or tribal designs just for the artistry. They add some flair to your skin. Other men choose images of religious figures, verses of Scriptures, or popular quotes to remind themselves and others what they believe in. Others feature tattoos of tigers, warriors, and dragons to show their strength. Still others get tattoos of skulls, an hourglass, or death faces to say, “I know it’s coming and I’m not afraid.” Finally, many men get tattoos of their favorite superheroes, movie characters, video games, or sports team logos as a sign of where their interests lie.
