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:
Plenty of cultures from across the globe have used tattoos as a form of expression. Certain cultures have used tattoos as a part of many rites of passage, for beauty, or artistic purposes, as a type of warrior mark, to identify a tribe or a gang, and so on. But it’s pretty much clear that when it comes to cultures from across the globe, tattoos have always stood for both belonging and marginality.
The "standard modality for tattoo removal" is the non-invasive removal of tattoo pigments using Q-switched lasers. Different types of Q-switched lasers are used to target different colors of tattoo ink depending on the specific light absorption spectra of the tattoo pigments. Typically, black and other darker-colored inks can be removed completely using Q-switched lasers while lighter colors such as yellows and greens are still very difficult to remove. Success can depend on a wide variety of factors including skin color, ink color, and the depth at which the ink was applied.
These types of tattoos have become popular because, besides being perfectly symmetrical and gorgeous, they can also carry a deep symbolic significance. In geometry, different shapes can be associated with different elements present in nature – the cube symbolizes the earth, the tetrahedron symbolizes fire, the icosahedron symbolizes water, and so on. In some cultures, it’s believed that having these tattoos on certain areas of the body can have a healing effect, can restore good health, or can provide a sense of balance. Plus, they’re stunning, which we’re sure you’ll recognize once you glance over our extensive collection of sacred geometry tattoos below.
Your next consideration should be where you want your tattoo. Is it something you want to show off, easily conceal or reveal, or a more personal project that only you will see? Your body will be your canvas, so it’s important to choose a portion of your anatomy appropriate to your art. Back pieces are exceptionally well suited to larger concepts, which you may want to expand at some future date. If you just want to start small, the bicep or the forearm are ideal for more contained show pieces, discrete emblems that can be worked into “sleeves”—either half or full—at a later time.
One small Greek study showed that the R20 method—four passes with the laser, twenty minutes apart—caused more breaking up of the ink than the conventional method without more scarring or adverse effects. However, this study was performed on a very small patient population (12 patients total), using the weakest of the QS lasers, the 755 nm Alexandrite laser. One of the other main problems with this study was the fact that more than half of the 18 tattoos removed were not professional and amateur tattoos are always easier to remove. Proof of concept studies are underway, but many laser experts advise against the R20 method using the more modern and powerful tattoo removal lasers available at most offices as an increase in adverse side effects including scarring and dischromia is likely. Patients should inquire about the laser being used if the R20 treatment method is offered by a facility as it is usually only offered by clinics that are using the weak 755 nm Alexandrite as opposed to the more powerful and versatile devices that are more commonly used. Moreover, dermatologists offering the R20 method should inform patients that it just one alternative to proven protocols and is not a gold standard treatment method to remove tattoos.
One of the most popular places for girls to get tattoos is around the feet and ankles. It seems less of a commitment to a life long piece of art on you because it’s less noticeable and easily concealable. The feet are also not generally considered the most beautiful part of the body, so it can be a great way of making them look prettier and adding some art to them.
