With the increasing demand for tattoos – both professional and amateur, demand for laser tattoo removal has also increased. According to the Harris Poll on February 12, 2008, approximately 17% of people regret having tattoos. The main reason given was that they were too immature when they got the tattoo.
Others said they regretted their tattoo because they fade over time while others said they "just didn't like it". Although there are other methods of tattoo removal that includes everything from creams to surgical removal, laser tattoo removal has become the gold standard for tattoo removal and has replaced other methods.
How does laser tattoo removal work?
Laser tattoo removal works by targeting the tattooed area with a pulse of laser energy at a particular wavelength. The ink in the skin absorbs the laser energy causes it to 'break', allowing the body to absorb naturally over a period of 6 to 8 weeks. After a period of 6 to 8 weeks, another session is done. Usually, it takes between 5 and 15 sessions before the tattoo fades enough so that it can not be seen.
There are many lasers used for all sorts of cosmetic procedures and there are a number of different lasers used to remove tattoos. These vary in the level of wavelength, pulse duration and energy. Some lasers can vary in the wavelength of light and the size of the spot. Varying the wavelength and pulse duration is important. Different colours of ink absorb light better at specific wavelengths and lasers with shorter pules are safer and more efficient.
