Tattooing is the mechanical introduction of foreign insoluble pigments into the dermis to produce a permanent pigmentation of the skin. Types of tattoos General decorative tattoos are painted on the body beforehand, and then some insoluble pigments, such as ink, indigo or vermilion, are pierced into the skin to make it a permanent pigment spot. Decorative tattoos are divided into professional, amateur and cosmetic. In addition, it can also be due to glass, metal, clay or carbon-containing substances and other foreign objects at high speed splash into the normal skin or with trauma into the skin, caused by traumatic tattoo. Professional tattoo pigment when injected into the dermis layer of the skin, the skin shallow layer of almost no pigment, the color is uniform, where the red pigment is a mercury agent, yellow is cadmium, green is chromium, blue is cobalt. Red and yellow are easier to fade with time, professional tattoos are more difficult to remove than amateur tattoos. Amateur tattoos The color is not uniform, can be distributed in the dermis at different depths, mostly gray or blue-black, the pigment used is easy to break, the tattoo’s edges are not sharp, the color pattern is not very sharp. Cosmetic tattoos are mostly tattooed lips, eyeliner, eyebrow tattoo-based type of tattoo, often using red, black or brown pigment, often containing divalent iron ions or iron trioxide. Traumatic tattoos foreign bodies into the skin at varying depths, can show different pigmented deposits of grayish-blue to black, with the increase in years will form hard nodules. How to remove tattoos According to the different types of tattoos, type and treatment, and according to their color and other characteristics to adjust the energy and spot, so that the effect to maximize the number of times to minimize the treatment, the most used today to go to the tattoo instrument is the ultra picosecond laser. What is the ultra picosecond laser? As the name implies, ultra picosecond laser is a laser skin care, picosecond units of laser light to break up melanin particles, remove skin spots, tattoos, but will not harm the surrounding skin, restore the skin’s whiteness and tenderness. Do you know what the original purpose of the development of picosecond laser is? Surprisingly, it is to go to the tattoo, especially the traditional Q-switched laser can not remove the yellow, green, red and other color tattoos, later people found that the use of picosecond laser treatment of other skin problems, the effect is also surprising, and now it is the development of a new generation of laser instruments super picosecond laser, so the skin laser indications are very wide: 1, large area to tattoo; 2, benign pigmented lesions (freckles, sun spots, age spots); 3, liver spots; 4, uneven skin tone; 5, acne scars; 6, red and black moles; 7, fine wrinkles. General tattoos with Q laser, depending on the composition of the potion used for your tattoo, simple dye can generally get rid of clean, but if it contains heavy metals is not good to get. Removal of tattoos after the operation to follow medical advice generally will not have scars, but there is hyperpigmentation and chromatic aberration phenomenon. Nowadays, the ultra picosecond laser breaks up the pigment of the tattooed eyebrows, and the body’s phagocytes gradually transfer the pigment. Laser eyebrow washing to treat the number of times with the color of the dye and the amount of eyebrow related, simple lines and shading graphics, less pigment tattoos, the laser treatment can be more satisfactory results, complex graphics, more pigment tattoos need to receive multiple treatments. For example, the number of eyebrow washing is generally 1-2 times, cleaning thoroughly, the effect is good, leaving a small chance of discoloration. The shorter the laser pulse time, the better? According to the famous “selective photothermolysis principle”, the shorter the action time of the laser, the shorter the target tissue absorbed by the accumulation of laser energy is less likely to spread to the surrounding tissue, the energy is limited to the extent that the target needs to be treated, the protection of the surrounding normal tissue, so the treatment of selective is stronger. The ultra-picosecond laser pulse width is only one percent of the traditional Q-switched nanosecond laser, in this ultra-short pulse width, the light energy can not be converted into heat energy, almost no photothermal effect, and the target is absorbed by the volume of the extremely rapid expansion, resulting in photomechanical effect is burst and torn into small fragments, more selective, can make pigmented lesions in a shorter number of treatments, resulting in stronger efficacy. In a nutshell, “the ultra picosecond laser breaks down pigment particles more completely, while causing less damage to the surrounding tissue. As an analogy, if we compare the original pigment particles to rocks, the traditional Q-modulated laser can break these rocks to the size of pebbles, but with the super picosecond laser, it can break them to fine sand, so the absorption efficiency of the pigment fragments is greatly improved. Better results can be achieved with fewer sessions, greatly reducing the rate of re-darkening. The side effect is a temporary re-whitening of the area, the more pigment, the more pronounced the re-whitening, but also indicates that the treatment was effective. After laser treatment, pigment particles metabolism takes a long time, the final treatment effect may take 2 to 3 years to judge, so it is recommended that the removal of tattoos difficult patients can extend the treatment interval to reduce the number of treatments. Post-operative care 1, after treatment, the treatment of local redness and swelling, you can use pure water cold spray or ice water wet compresses and other methods, generally within a day can subside. 2, during the healing of the wound to prevent infection is very important, some treatment will appear after the local layer of scab, generally 1-2 weeks after the scab on its own, before the scab off, local do not touch the water, do not use cosmetics, do not peel off the scab, 1-2 times a day can be used externally antibiotic ointment. 3, after the laser treatment try to avoid sun exposure, to avoid inflammation after the pigmentation, can be used externally sunscreen.
