tattoos are their old body art can be traced back to the Bronze Age, and found that the then frozen body with many tattoos. The Paleolithic Age found for tattoo equipment. Egypt's dry body has also made it clear that they have a tattoo, and prefer these tattoos. tattoo, with a body as canvas, pigment for paint, you can describe religious beliefs, people, personal views, as well as expressing pleasure, home, frustration, and acknowledge, sexy, angry, and so on. It is reported that tattoo, in the United States universities in the life of prevalence rates of 24 per cent.


The skin surgery and beauty skin in clinical practice, tattoo removal is not uncommon. Total there are 5 types of tattoos: an amateur, professional, beauty, medical and trauma. Amateur tattoos and professional multi-color tattoo, in contrast, the treatment needed fewer in number. To remove tattoos, needs assessment of other factors, including tattoo area, patient age and the patient's skin type.
Laser and tattoo, interaction between the physical mechanisms, as well as tattoo particles broken process is still not completely clear. Non-traditional to remove tattoo, is still in the study, and will lead to further development and reform. Current research is concerned with a new selective Q - Switch System for picosecond laser.


As shaded


 such as color-coded
in accordance with tattoos color pigments can be very clearly the classification tattoos. The most common color is black, but in the past few 10 used in more colors such as red, blue, green, brown, Color tattoo, more and more popular. Often, 2 or 2 of the above color mixed into a special color or a new color, such as white and red mixed in pink.


According  type
tattoo, generally divided into 5 categories: amateur tattoos, professional tattoos, medical, tattoos, beauty, tattoo, and traumatic tattoos.


a) Professional tattoo professional tattoo artists, tattoo, the experts and they know how to tattoo, lasting. This means that they will be for the full amount of ink, and sufficient depth and appropriate elements of the tattoo, for a number of years or 10, leading to intensive and full of ink. tattoo artists have the right to determine the ink, such as an amateur may not use the metal oxide. In the skin The more ink will need laser treatment more. And, with the ink, for example, containing 3 carbon dioxide 2 iron ink, laser is very difficult to remove.


b) an amateur tattoo, this is the first 2 common tattoo types, by not fully skilled individuals. Generally speaking, amateur tattoos are common in young people and most formed a group. An amateur tattoo, there are a number of ways. It was with him, and made the tattoo gun or the simple pin manually stabbed. Ink can be a pen ink, charcoal or soot. limitations because allergic reactions or light-sensitive dermatitis, rare red (mercury), Yellow (cadmium), green (chrome) and blue (cobalt) color pigments. In addition, Black, other colors in amateur tattoos, rare. The tattoo, is light in color and is an organic ink forms, they can be easily removed. It is important to note that if the water in the skin of the position is very deep, for example with the needle penetration, and may the laser treatment of out-of-scope. However, as long as tattoos are visible to the human eye, it can be used Q - Switch laser to remove.


c) The Medical tattoo, the tattoo is rare, the medical experts for a purpose which is placed, such as mastectomy reconstruction after patient's nipples. Medical tattoos are also used in radiation therapy for identification.


d) beauty tattoo this tattoo, the tattoo industry is recently developed, used to enhance physical performance. Lasting tattoo, as a cosmetics the benefits of IT, water-saving and low-cost. It can be done by professional tattoo artists, or a dermatologist. Beauty tattoo, consist of a mixture of ingredients, pink, red, and flesh tones often contain 3 carbon dioxide 2 iron and 2 titanium dioxide.


e) trauma, tattoo, traumatic tattoos are the objects of tattoos, such as smoke particles, sand, metal, glass, gunpowder, asphalt, dust or oil products, such as force, the leather. Small black to the blue particles can be a very deep-rooted in the Remove is very difficult. The most common damage is the face, hands and eyes. Traumatic tattoos need special attention, because these particles may be laser treatment risks of response.

Skin lymph tissue hyperplasia (CLH)
CLH or false lymphoma contain different types of benign T or B lymphocyte proliferative response, which can be an ad, which can also be a result of drug or contact dermatitis irritation. Currently, there are approximately 20 tattoo induced CLH is reported, they can be a symptom of or itchy, one or more, or swelling. The main thing is the red, but also with the blue and green. This response and MOSS, or meat of sprouts as response to. The tattoo, The CLH reports is a series of 7 tattoo patients CLH. They had a skin biopsy, as well as the spot-test and check T and B cell response. According to the report, only 1 tattoo patient CLH development of lymphoma.


laser to remove tattoo
removal tattoo, there are many ways, including cut, frozen, sanding, salt corrosion, burning, red, freezing, as well as burning, CO 2 laser, and so on. These methods are often unable to fully remove tattoo or lead to varying degrees of scar formation. Outside the cut can be considered as a single therapy to remove tattoos, leaving a linear scars, but in the extremities of the tattoo, scars may be extended. surgical removal can be used for small-scale, low-tension areas of the tattoo.


The laser is used to remove tattoos, for example argon laser and CO 2 laser. Argon laser continues to be 488 nm and 514 NM, green, or blue laser energy, and this can be skin tattoo particles selective absorption, but tattoo, absorbs the heat will spread to the surrounding skin and cause scarring. Although CO 2 laser can be more evenly or scorched skin superficial level, but to remove tattoo, the result of which was not fully and easy-to-lead to scar formation.


The current technology in general use Q - Switch or quality conversion (QS) laser. The laser is selectively the hot theory. This means that the laser through selective absorption and wavelength shorter than the relaxation time of the pulse duration to redirect damage tattoo pigments. This has resulted in skin, leather and skin annex the minimum damage, selective damage as laser metropolis in the target color. tattoo ink is an external source of mission metropolis.


Q - Switch is a from the laser in the media suddenly release all of the activation state of the energy from the second pulse laser technology. Exposure to the laser to the white response. In addition, the appropriate use of this laser, scar formation of risk less than 4.5 per cent. In one study, such as Leuenberger found Q - Switch to blue-black tattoo, with the highest rate of clearance, but it can also have a long-term color and missing the highest rate of occurrence. Another side, Nd: YAG laser is not pigments and missing.


tattoo, remove the laser theory
a) The most basic view is that laser is tattoo pigments absorption, because these pigments are in a variety of colors, and therefore need to be multi-wavelength laser to remove tattoos. Using the laser to remove most of the "visible" color, and/or change the color pigments, These pigments used at the start of the laser is invalid. This has led to a tattoo, it is very difficult to deal with.


b) wavelength is longer PENETRATE THE SKIN deeper and less divergence. In addition, wavelength, spot size also determines the laser cross-cutting depth. The edges will be diffused, and therefore reveals the Plena divergence rate high, and they cannot reach skin deep. For this reason, in the tattoo application when the spot to replace increase energy. Because the increase of energy major role in shallow, leading to greater damage and scar formation.


C) when given a laser tattoo treatment is no longer valid, you need to consider the other laser.


d) any of the laser can be used to treat black tattoos, because black absorbs all wavelengths of light. Should the tattoo color select the laser, because with a tattoo, color consistency of wavelength can be used to remove the tattoo.


e) tattoo, to remove the exact mechanism is still not clear, but laser can damage and heat, light chemical or light and sound led to an instant change tattoo particles optics.


Biopsy, histology and electron microscopy analysis shows pigments have collapsed into small pieces, and then by the macrophage engulf or the lymph system troubleshooting. Pigment particles are also the changes in the structure. In accordance with the laser dose, treatment can be a temporary white. White is the color rapid localized heating result in gas or plasma formation, as well as subsequently in leather and skin regeneration. White response of the laser treatment occurred immediately after, and 2 - 5 days after the crust leather instead. The experimental treatment can be for the laser to the skin types of responses and tattoo, the laser's response with the best choice. A small pilot treatment site can be within 1 month re-evaluation. You must instruct the patient after the treatment in the treated area with petroleum jelly lubricant until crust leather off.

 Q - Switch 532 nm Nd: YAG laser
Nd: YAG laser (1064 Nm) can double the frequency, the general wavelength optical crystal (potassium titanium phosphate - KTP) 532 nm wavelength of green light.


In addition to being used for remove red, orange and purple tattoo, Q - Switch 532 nm Nd: YAG laser joint local with the beauty can safely and effectively treat the red ink tattoo reaction.


Special handle can also be used to 532 nm wavelength conversion to 585 nm wavelength to remove blue ink, can also be transformed into a 650 nm wavelength for green ink removal.


 Q - Switch 694 nm Ruby laser
Q - Switch Ruby laser (QSRL) to remove tattoos by Goldman prove for the first time, he has proved that with the second pulse of the Q - Switch Ruby laser can remove black pigments tattoo and does not cause scars, but Ms pulse will result in treatment of thermal damage. This has led to a tattoo, skin damage is not fully subsided, so Goldman attempt is considered to be failed. After 3 years, other researchers have proved the QSRL can successfully remove blue color and black tattoo, and there are no injuries, and the Treatment 3 months after the biopsy shows no tattoo pigments, and there is no thermal damage. Anderson and Parrish such selective optical hot role through to the given wavelength laser to remove in the skin of the target organization, and does not cause tissue damage around. Instead, use MS pulse of the unit, such as intense pulsed light can cause the tattoo to remove and cause scar formation.


There is more than one study shows the QSRL laser can effectively remove blue, black and green amateur and professional tattoos. It was also reported by QSRL can be removed after the explosion of the traumatic tattoos.


 Q - Switch 755 nm jade jewelry laser
Q - Switch 755 nm jade jewelry laser pulse width is 100 ns, spot size is 3 MM, repeat rate is 1 Hz. It is therefore in the reliability, speed, and repetition rate are better than the earlier of the Ruby laser. It is used to remove green, blue, and black tattoos, and can be considered as remove green tattoo. In one study, 25 patients with jade jewelry laser treatment amateur and professional tattoos and had proved to be 95 per cent of the tattoo removal rate, average treatment times of 8.9. This shows that the jade jewelry laser can be safe and effective to remove blue and black tattoos.


The other 1 studies, jade jewelry laser used to remove 24 professional and 18 amateur tattoos, the former (8.5 times) than the latter (4.6 times) the required treatment.


Zelickson research 3 types (Ruby and jade jewelry and Nd: YAG) Q - Switch laser treatment tattoo, clinical, histology and micro-structure, and the conclusions are red, brown, and orange color of the Nd: YAG response best, jade jewelry laser to remove blue and green color the most effective, Q - Switch Ruby laser to remove purple and deep purple color the most effective. 532 nm wavelength Nd: YAG laser to remove red pigment. All of the lasers can be effective in removing black pigments.


 Q - Switch 1064 nm Nd: YAG laser
Q - Switch Nd: YAG laser can launch 2 wavelength, 1064 nm and 532 Nm. This feature makes it a 1064 nm wavelength treatment dark tattoo pigments, The 532 nm wavelength to remove red and orange pigments. There are several studies have demonstrated Q - Switch 1064 nm Nd: YAG can effectively remove tattoos
