Description

Tattoos have now become a part of trending culture in the society. Lot of people do tattoo for beautification or fashion. It has become conventional among young people to present and express their self. One of the methods of removing tattoos is by laser therapy and dermabrasion. While lasers are the most common method of tattoo removal. Tattoos are created by injecting colored pigment into the skin. Regardless of who or how the pigment is injected, the marks or designs are relatively permanent. People turn to physicians to have tattoos removed. Fortunately, there are several methods for tattoo removal, which have proven successful. In most cases, however, some scarring or color variations remain. The conspicuousness of these blemishes depends upon several factors including size, location, the individual's healing process, how the tattoo was applied, and length of time it has been on the skin. METHODS OF TATTOO REMOVAL LASER In recent times, many physicians consider laser surgery one of the best methods of tattoo removal. Today, the Q-switched Nd:Yag, Q-switched Alexandrite and the Q-switched Ruby are among the most frequently used lasers for the removal of unwanted tattoos. They are all employed in a similar manner. A local anesthetic cream to numb the skin can be applied prior to the treatment. Pulses of light from the laser are directed onto the tattoo breaking up the tattoo pigment. Over the next several weeks the body's scavenger cells remove the treated pigmented areas. More then one treatment is usually necessary to remove the entire tattoo at intervals of eight weeks. RESURFACING Resurfacing of tattoos removes only the top layers of the skin bearing the pigment of the tattoos. This technique may not always remove the pigment present in the deeper layers of the skin. Resurfacing can be done through Dermabrasion Ablative lasers like CO2 laser and Erbium Yag Laser Both these techniques may require local anesthesia. Because some bleeding is likely to occur a dressing is applied immediately to the area. What Results Can Be Expected? Regardless of which method of tattoo removal is used, some color variations are possible to remain. Healing time varies depending upon the size and depth of the tattoo, the procedure used and the patient's healing process. How many sessions are required for tattoo removal? Complete laser tattoo removal requires as many as 8 to 12 treatments, typically spaced at least 8 weeks apart. At each session, some but not all of the tattoo pigment particles are effectively fragmented, and the body removes the smallest fragments over the course of several weeks. The result is that the tattoo is lightened. Remaining large particles of tattoo pigment are then targeted at subsequent treatment sessions, causing further lightening. The number of sessions and spacing between treatments depends on various parameters, including the area of the body treated and skin color. Forearm and ankle tattoos generally take longest. What are the possible side effects and complications of tattoo removal? Hyper pigmentation (dark spots) or hypo pigmentation (white spots) may sometimes occur; however these are more common in darker skin. ‘Paradoxal darkening’ of a tattoo may occur when a treated tattoo becomes darker instead of lighter. This occurs more often with flesh tones and lighter colored tattoos and maybe avoided by doing a ‘patch test’; where the laser is applied to one or two test sites prior to a decision to treat a full tattoo. Scarring may occur when inappropriate laser energy is used. Transient textural changes are occasionally noted but often resolve within a few months Local allergic responses too many tattoo pigments have been reported and allergic reactions to tattoo pigment after Q-switched laser treatment is also possible
