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:
Some wearers decide to cover an unwanted tattoo with a new tattoo. This is commonly known as a cover-up. An artfully done cover-up may render the old tattoo completely invisible, though this will depend largely on the size, style, colors and techniques used on the old tattoo and the skill of the tattoo artist. Covering up a previous tattoo necessitates darker tones in the new tattoo to effectively hide the older, unwanted piece. Many tattoos are too dark to cover up and in those cases patients may receive laser tattoo removal to lighten the existing ink to make themselves better candidates for a cover up tattoo.
We’ll start with this ghost design. In recent years there has been more of a movement towards smaller, minimalist style tattoos, rather than the traditional ink heavy ones. It also shows that girls are not limited to only getting ‘girly tattoos’. The cartoon ghost is a fun, whilst not been too spooky. Smaller tattoos are also becoming more popular nowadays as they are more affordable and often people can get a few smaller tattoos for the same cost as a bigger one. Not to mention they are also a lot easier to hide/conceal should you need to for work.
