Many people who have tattoos and permanent makeup, want to eliminate them. Either because the drawings are placed in their teens and are no longer rated because they are poor or simply to be replaced with others. Studies in recent years show that the motive for the removal of tattoos are important events in life, a new job, problems with clothing etc.
In parallel with the placement of tattoos the techniques for their removal develop. The process is long and difficult, as in the past were also used quite extravagant ways – injecting extracts of wine, lime, garlic and even pigeon excrement. Today, most effective and safest way to remove tattoos are the laser systems Q-Switched.
Tattoos comprise a pigment introduced artificially into the skin. All pigments have a specific light absorption spectrum. Therefore, the laser must pass the precise light absorbed by the pigment. Different dyes require different colors of the laser beam. For example, red light absorbs more strongly green pigment. Yellow, green and fluorescent inks are more challenging to remove compared with black and blue inks. Fresh tattoos are removed more difficult, since they contain high concentrations of titanium dioxide, which is highly reflective. Laser treatment breaks into small particles the pigment. These small particles are removed from the body due to phagocytosis by macrophages.
Q-Switched lasers are considered the gold standard in the removal of tattoos. The power and duration of the laser pulse are important parameters because powerful, short bursts are safer and more effective in removing tattoos. In Q-Switched lasers radiation is such that the colors absorb impulses much stronger than neighboring elements of the skin. When absorption of laser pulses dye grains are broken down into microscopic particles without damaging surrounding tissue. Cells of the immune system capture these particles and gradually eliminate them within a few weeks after the procedure. Advantage of our laser system is that the laser spot is square. Thus the pulse energy is evenly distributed and ensures greater safety of the therapy. There are several main types of laser systems Q-Switched, as each is effective for removing tattoos in a different range of the color space. Multicolored tattoos almost always require the use of two or more wavelengths. The new generations of laser systems from the family of Q-Switched allow combining multiple wavelengths and can remove all colors. In this regard, the working in Dr. Magdalina Gyurova’s Medical center laser system of Quanta System is a combination of three wavelengths and is the only of its kind in the country:
1. Q-Switched Nd: Yag: 532 nm
This laser creates green light with high ingestion of red, orange, purple and less of yellow pigments. This wavelength features high absorption by melanin, so it is suitable for removal of pigmentation and solar spots.
2. Q-Switched Ruby: 694 nm
This laser creates red light that is absorbed by green and dark dyes of tattoos. This is the best length for the removal of blue ink. Since this type of laser has a high absorption of melanin, it has a good effect in the treatment of changed pigmentation of patients with fair skin.
3. Q-Switched Nd: Yag: 1064 nm
This laser creates light close to infrared, and is absorbed by all the dark pigments of the ink. It is therefore appropriate to remove black, brown, gray, dark blue colors. This wavelength is poorly absorbed by melanin and therefore this laser is suitable for people with darker skin.
The combination of these three wavelengths in Q-Switched mode allows removal of various color pigments.
Complete removal of tattoos requires a series of therapies. The number of procedures and the interval between them depends on various parameters including the treated area and the skin color. For example, deletion of drawings on the limbs takes a long time. It is recommended that the gap between the two treatments is 4 to 7 weeks.
The successful tattoo removal is an individual process and depends on skin type, location of the tattoo, ink color, amount of dye, regenerative abilities of the individual and the manner of placing the drawing.
The procedure for removing tattoos is not painful, but it also is not comfortable. Many patients define it as more unpleasant compared to the placing of drawings, and the feeling is described as scald or abrasion. Therefore, before the therapy can be used numbing cream.
Immediately after the procedure is obtained slight swelling of the treated area, the skin fades. Redness in neighboring areas usually resolves in 24 hours and in the treated areas appear scabs that peel away for about 14 days. The mere pigment of the tattoo can be found in the crust. The fading of the tattoo can be seen in the next 8 weeks. It is possible to appoint antibiotic treatment, although laser applicators are sterile and there is no need of such.
For some patients who have undergone tattoo removal with Q-Switched laser can occur temporary changes in skin pigmentation. Pigment spots disappear within a few months when apply broad-spectrum sunscreens. If a patient is prone to pigmentation, are recommend longer intervals between treatments. Patients with keloids should be warned about an increased risk of scarring.
When removing tattoos are possible allergic reactions because Q-Switched lasers activate inks. Redness and itching may occur after treatment – especially when the ink is red or yellow, because these colors contain mercury sulfide and cadmium sulfide.
