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:
Laser tattoo removal is uncomfortable - many patients say it is worse than getting the tattoo. The pain is often described to be similar to that of hot oil on the skin, or a "snap" from an elastic band. Depending on the patient's pain threshold, and while some patients may forgo anesthesia altogether, most patients will require some form of local anesthesia. Pre-treatment might include the application of an anesthetic cream under occlusion for 45 to 90 minutes or cooling by ice or cold air prior to the laser treatment session. A better method is complete anesthesia which can be administered locally by injections of 1% to 2% lidocaine with epinephrine.
Card symbols have long been popular symbols to get inked. The ace of spades is usually the most popular one to get but not far behind are the Queens. The queen of clubs symbolises a strong willed and positive person. Tattoos in between the fingers usually need to get redone every few years as they do fade due to the amount of rubbing that occurs there.
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.
