Tattoo Removal - Method And Risk

 
 
 
This was done by means of tattoo removal in the history of different tattoos. While the tattoo is permanent, you can now carefully remove in whole or in part. And the burdens and sorrows to remove some tattoos are usually much, much greater than the burdens and sorrows of their application.
Methods for removing tattoos with lasers to include dermabrasion, salabrasion (rubbing the skin with salt), freeze, and excision which still sometimes used in combination with skin grafts for larger tattoos. Some early models of injection tattoo removal or application of garlic, wine, lime, or pigeon droppings. This is done by a laser to remove tattoos continuous wave laser at first, then with a laser Q-transformation, which became commercially available in early 1990. Today, the "laser tattoo removal" usually refers to the removal Stain with a non-invasive laser Q-transformation. Usually, you can remove the black ink and a dark color, more fully.

Motivation for tattoo removal
In the U.S., approximately 17% of people with tattoos and experienced some regret. A survey conducted in 2008, the most common reasons, unfortunately "too small when I got a tattoo" (20%), and "permanent" and was "a sign of life," I (19%), and I said "I do not like "(18%). For the survey showed previously that 19% of British people with tattoo regret is suffering, as well as 11% of Italians with tattoos. Tattoo removal patient study conducted in 1996 and 2006 and provide a clearer picture. These patients usually get tattoos in their late teens or twenties, and more than half of them women. About 10 years later, the patient's life can change, and more than half of patients reported they "suffered embarrassment". New job, and problems with clothes, major life events (marriage, divorce, baby), often cited as a motivation.

Coverage
Some users and decided to close the unwanted tattoo with a new tattoo. It is known that as a cover. This can make art to cover the old tattoo completely invisible, although this will depend on the size and colors and styles and techniques used in the old tattoo artists and tattoo skills. Tattoo cover the first takes a darker tone on a new tattoo to effectively hide the piece, the elderly and unwanted. Many of the tattoo to cover the light itself and in those cases the patient may get a tattoo ink laser to reduce the list to be the best candidate for tattoo cover-up.

Method
It is most commonly done with a tattoo removal lasers that interact with the ink of the tattoo and broken. The ink is absorbed and then broken from the body, mimicking the natural fading that the exposure time or the sun would create. All tattoo pigments have specific absorption spectra of the light. Must have a tattoo laser capable of delivering enough energy in the spectrum of specific absorption of the dye to provide an effective treatment. Tattoo dyes, inks, such as yellow, green and fluorescent harder to treat than the darker blacks and blues. These pigments are more difficult to treat because they have absorption spectra that are outside or on the edge of the emission spectra are available in tattoo removal laser.
It is widely considered the gold standard method of treatment to remove tattoos, laser tattoo removal requires frequent visits. The Q of the shift of the laser from the National Institutes of Health recently lead to scarring only rarely, usually used only after the application of local anesthetic. And areas with thin skin are more likely to scar thickness of the skin areas. There are several kinds of laser Q-shift, and each effective in removing several different from the spectrum of colors. Laser developed after 2006, and provides multiple wavelengths, and can be treated successfully wider than the pigment of the tattoo by Q-shift laser first.
Another type of tattoo removal is a manual method or a machine. This practice is not very predictable, and uses a particular type of gel, and are usually mixed with salt, which is tattooed in the skin causing the tattoo ink into the dermis to bond with or moved from the gel and migrate to the surface of the skin. Scarring, and tissue changes of tissues, keloid, healing for long periods, pain, discoloration (hyper-and hypopigmentation) and very high to keep the ink with the means of removing non-laser, and people who have this type of treatment is exposed to a great responsibility. These methods are very rare in modern countries that have been replaced by a laser Q-transformation. Still other ways, including thermal injury, cryotherapy and dermabrasion, and used, but with unexpected results and the same negative side effects.

Mechanism of laser action
For the first time to experimental observations of the effects of short-pulsed laser in late 1960. In 1979 and used for the argon laser for tattoo removal in 28 patients, with little success. In 1978, carbon dioxide is also used, but usually caused by scar tissue after treatment was not until 1980 that the laser Q-transformation and has become a practical business sense. He published the first, which describes the laser tattoo removal has written this article from a group at Massachusetts General Hospital in 1990.
 Tattoo is compound is made up of thousands of tattoo pigment particles depends on the skin. While the growth of human and natural healing process and the removal of small particles of Foreign Affairs of the skin, a permanent tattoo pigment particles that are too large to be removed. The laser treatment causes the tattoo of heat and fragments of pigment particles into several pieces. Then remove the small amounts of biological processes in the body naturally.
Tattoo removal laser is the successful application of the theory of selective photothermolysis (LPS). Laser tattoo removal, selective demolition of the tattoo pigment LPS depends on four factors:

  •  Must be the color of light to penetrate deep enough into the skin to reach the tattoo pigment.
  •  Must be that the color of the laser beam is absorbed by the tattoo pigment top of the surrounding skin. Tattoo pigments thus require lasers of different colors. For example, the absorption of the tattoo pigment red green light.
  • The length of time (pulse duration) of the laser energy must be very short, so that the tattoo pigment is heated to a temperature from falling apart before it can dissipate heat to the surrounding skin. If not, able to heat the surrounding tissue causing burns or scars. Laser to remove tattoos, and should be of this period in the order of nanoseconds.
  • Enough energy to be delivered in each laser pulse to heat the pigment to the fragmentation. If the energy is very low, the pigment is not a piece and deletions will not happen.

Q-shift laser is the only commercially available that can meet these needs. Although they are rare, and tattoos can be successfully treated with the question of the mucosa to move the laser is also

Laser parameters that influence the results
It uses some of the colors of laser light (laser wavelength is measured and energy) to remove tattoos, visible radiation, near infrared. The lasers are best for different colors have different tattoos. As a result, multi-color tattoo removal is almost always requires the use of wavelengths of two or more. Usually described as a laser to remove tattoos from the amplifier and the support is used to create the wavelength (measured in nanometers (nm)):

  •  Q-transformation frequency doubled Nd: YAG lasers: 532 nm. This creates a green laser light that is absorbed by the target of red and orange. Especially useful to tattoo pigment in red, orange, and this wave is absorbed by melanin (the chemical that gives skin color or brown), which makes effective wavelength to remove age spots laser point or a
  • Q-shift Ruby: 694 nm. This creates a red laser light absorbed by the tattoo pigment and dark green. Is absorbed as a result of the high laser by melanin may occur undesirable side effects such as changes in skin pigment for all patients, except white.
  • Q-shift Alexandrite: 755 nm. Similar to the Ruby laser, Alexandrite create a red light that is absorbed by the tattoo dyes and dark green. However, the color of the alexandrite laser is slightly less absorbed by the melanin pigment, so that the laser has a slight flexion of the changes of the pigment of the laser unwanted sapphire. Q-switch Nd: YAG: 1064 nm.
  • Laser creates a bad light is absorbed near-infrared (invisible to humans) by the melanin, which makes the laser is only suitable for dark skin. It also absorbs the laser wavelength of tattoos dark pigment, and everything is safer wavelength for use on the network due to the low absorption of melanin and the absorption of low hemoglobin levels. This is the wavelength of choice for the removal of tattoos types of darker skin.
  • Units are available for some of the dye laser to convert 532 nm to 650 nm and 585 nm of systems that allow laser light. Safe and effective for the treatment of multi-color inks tattoo

Pulse width or duration of the pulse laser is a critical parameter. All organs of the Q-shift laser has a pulse width corresponding to the removal of tattoos. However, the shortest laser pulse has a removal method which is safer and more efficient because the height of the pulses of force majeure.
Spot size, or width of the laser beam, affects treatment. Optical light scattered in the skin, such as car headlights in the fog. Large locate a slight increase in the effective depth of penetration of the laser beam, thereby allowing more effective targeting of the tattoo pigment deep. Larger spot size also helps to make treatment more quickly.
Fluence or energy level is an important consideration. Fluence is measured in J per square centimeter (J / cm ²). What is important for obtaining the treatment in environments that are high enough to break the particles of the tattoo.
Repetition rates to help make treatment more quickly, but nothing to do with the effects of treatment.

Number of season Tattoo removal laser treatments are needed
Complete removal of the tattoo laser requires several treatment sessions, usually at a distance of no less than eight weeks. The treatment is often more than eight weeks increases the risk of side effects and there is a need to increase the level of manufacture of the ink. Relations caused by the treatment sessions on 4 and 6 weeks and more dischromia scars and can be a source of liability for physicians. In each session, and fragmented in an effective way some but not all of the pigment particles tattoos, and the body eliminates the smaller parts for several weeks. The result is that the ease of tattoo from time to time. From the rest of the tattoo pigment particles are targeted and then in the next session of treatment, with consequent greater lightning. Number of courses and the distance between the treatment depends on several criteria, including the area of ​​the body treated and skin color. Tattoo is for the parties, such as the ankles, usually take longer. As the tattoo to fade your doctor may recommend that patients wait months between treatments to facilitate the resolution of ink and minimize the unwanted side effects.
Amount of time required to remove the tattoo removed and the success varies with each individual. Factors affecting the following: skin type, position, color, and a quantity of ink, scarring, or change of the fabric, and the layers. Will health care in the past only imagine the amount of care the patient requires a little 'frustrating for the patient. Measure of predictive, "Kirby, Desai Scale", developed by Dr. Will Kirby and Dr. Alpesh Desai, dermatologists who specializes in tattoo removal techniques, to assess the probability of success and the amount of maintenance required by laser removal of tattoo, giving the physician with the quality of the switched Nd: YAG (neodymium doped yttrium aluminum garnet) laser selective photothermolysis combined for eight weeks between treatments.
Kirby, Desai scale gives numerical values ​​for six parameters: skin type, position, color, and a quantity of ink, scarring or tissue change, and layers. Then the value of the parameter is added to produce a total value of which will indicate the estimated number of treatments required to remove the tattoo with success. Experts recommend that the size of Kirby, Desai used by all practitioners of laser tattoo removal, before the start of treatment to help determine the amount of maintenance required to tattoo removal and laser treatment and an indication of the success tattoo removal. Before 2009, doctors and have no scientific basis used to estimate the number of treatments required to remove the tattoo and use of this measure was applied to the tattoo removal laser.

Pain during the treatment period
A tattoo removal of the laser to be uncomfortable, but is very good in most cases. The pain is often described as similar to hot oil on the skin, or "slap" of elastic. Depending on the threshold of pain for the patient and, although some patients can remember exactly anesthesia, most patients require some form of local anesthesia. Pre-treatment may include the application of anesthetic cream under occlusion for 45 to 90 minutes before laser treatment sessions. In very rare cases, if you need to numb everything, and can be managed locally by injection of 1% to 2% lidocaine with epinephrine.
He noted the publication of reports indicate that patients who received local anesthesia by injection may require additional treatment such as mechanical injection caused edema, off tattoo ink, which in turn makes it difficult for the laser light to work on a specific ink particles. This can also increase the risk of scarring and / or further treatment.

Side effects and complications
Almost half of patients who were treated with the laser Q-transformation to remove the tattoo show some temporary changes in skin color normal. These changes usually resolve within 6 to 12 months, but rarely may be permanent. It is associated with hyperpigmentation to the color of the patient's skin, skin type IV, V and VI are most likely regardless of the wavelength used. Twice daily treatment with hydroquinones and broad-spectrum sunscreen hyperpigmentation usually resolves in a few months, however, in some patients, and may extend the decision. Changes in the tissue and the media in some cases, but in many cases be completed within a few months, however, changes in the tissue and scarring is very rare. If the patient is susceptible to variations of the pigment or texture, and is recommended for long periods of maintenance. Moreover, if the patient's treatment blisters crust forming or another, it is imperative that manipulate the minor changes of the skin. The judiciary in the early abrasion of the cortex increases the likelihood of scarring. In addition, patients who have a history of hypertrophic or keloidal scars needs to warn of increased risk of scarring.
Been reported in the response of the sensitivity of tattoo pigments premises are multiple, and the sensitivity of tattoo pigment after laser Q-transformation is also possible. Rarely, and when the yellow cadmium sulfide used to "illuminate" tattoo red or yellow, you may experience allergic reactions to light. A similar reaction occurs with red ink, which can contain cinnabar (mercury sulfide). Had erythema, pruritus, nodules, and even inflamed papules, verrucous, granular, or be present. It will only be a reaction to red ink / yellow. The treatment is to avoid a narrow, sunscreens, interlesional steroid injections, or in some cases, surgical removal. In contrast to the methods described destructive, Q-move laser and crowd ink on the production of systemic allergic reaction. Antihistamines have been used for oral steroids and anti-inflammatory for the treatment of allergies to tattoo ink.
Studies have shown tattoo pigment, a series of different dyes (which contain most of the iron oxide or titanium dioxide) to change color when irradiated with laser energy Q-transformation. Some tattoo colors including flesh tones, red, white, peach, light brown pigment contains a pigment and the blue-green tattoo, turn black when it is irradiated with laser pulses Q-transformation. He has gray and black that is produced requires further treatment to remove. If the place of the dark tattoos can be treated after 8 weeks of a new tattoo dark like a black dye.
 Very rarely, non-Q-shift laser treatment, such as CO2 or argon laser, which are rarely offered these days, and blood vessels can rupture and aerosolizes network or device that needs protection plastic cones to protect the laser from the network operator and communications in the blood. He may wear protective clothing to the eye, if the operator chooses to do the laser.
By means of mechanical modifications or removal salabrasion tattoos, scars and pigmentation (hyper-and hypopigmentation), and high ink retention.
Can be used as a laser Q-move very rarely lead to the development of large bubbles. However, if the patient follows the instructions in the post-cure for the ice elevator, convenience, and the application of intermittent, should reduce the probability of the bubble and other side effects. Moreover, we should think about health care in the use of cooling equipment for the conduct of tattoo removal. While the evolution of the bubbles is a rare side effects that may result from the removal of the laser Q-shift, if the appropriate treatment and quickly by a healthcare professional, it is unlikely that the long-term consequences will occur.


Risk
Although the laser treatment is the gold standard method for tattoo removal, unwanted side effects of laser tattoo removal, including the ability to change the color of the skin as hypopigmentation (white spots, more common in dark skin) and hyperpigmentation ( dark spots) as well as changes in the tissue. Very rarely, scarring can cause serious burns, but this usually only happens when you do not care about the patients treated areas properly. Rarely, it can be "dark irony" of the tattoo is going on, and when tattoos were treated for no more than slight darkening. This seems to happen often with flesh tones, and pink, and make-up and cosmetic tattooing.
Some tattoo dyes containing metals that can theoretically break to toxic chemicals in the body when exposed to light. Has not been reported in vivo, however, has demonstrated in the laboratory;. It can also remove the laser from the shock be complex depending on the article in the coloring. In one reported case, which has led to the use of laser ignition integral part of debris fireworks
