Tattoos and tattoo removal have existed for a long time. From the moment that the tattoos were used as a form of punishment or branding, people have sought ways to remove them. Fortunately these days, the decision to remove a tattoo is usually related to personal preferences and changing everyone’s Outlook on life.Before lasers, tattoos could be eliminated with a multitude of ways, including the salt abrasion (Salabrasion), dermabrasion, acid removal, or sincere surgical excision. These methods were quite effective, but it was painful and left scars. Laser tattoo removal originally started as a way to burn a tattoo. Lasers like CO2 and argon lasers were used, but were not much better than a devastating surgical methods, leaving open wounds that have to heal over time. The advent of Q-switched laser was a critical moment in laser tattoo removal. Lasers work by an entirely different mechanism than abstract laser (the kind that destroys the skin). A q-switch is a hyper-rapid shutter that allows the emission of a very short burst of laser light, in nanodeyteroleptwn scale. The light is also to a very high energy, all within this short burst. The effect of tattoo ink is similar to throwing an ice cube in a glass of hot water-it cracks. The heat of the laser is absorbed preferentially by the tattoo pigment, but it happens faster than the ink particle can thermally expand, causing the shattering into tiny pieces. These smaller pieces are small enough to be digestible by white immune cells of the body and taken away to distant areas. As this process is repeated, the tattoo becomes lighter until it is almost invisible.Different ink colors react differently to laser treatment.There are 3 q-switched lasers are commonly used in the market today: Ruby, Alexandrite and Nd: YAG. Ruby was the first q-switched laser and works in a short wavelength 690 nm. This makes it effective for blue and green fake rose tattoos more than for others, such as black or red. Alexandrite 755 nm running at and is better for the Green tattoos. The YAG can be used both in 532 and 1064 nm, making it effective against both black and Red tattoo more than other lasers. There are certain colors that seem more resistant to laser treatment than others, with any laser. These include yellow, pink, and purple.Each laser tattoo removal treatment is quick. It can take half an hour or more to create a 3 inch tattoo, but a single laser session can last only 30 seconds! Typically, local anesthesia is placed before the treatment or in a small area can be injected with a local anesthetic. After the treatment, there is occasional blistering and bruising, but this is not necessary for the treatment to work. The lawsuits usually done every 4-6 weeks. A single tattoo can go almost after 3 treatments, but this is rare. Most often, tattoos require 6-12 treatments. Some inks are resistant to laser tattoo removal, because of their chemical nature. This is the case with metal-oxide tattoo pigments, such as iron and titanium oxides. Although it is still removable, it takes many more treatments.These days, laser tattoo removal is effective and safer than ever with the use of Q-switched laser. This takes time and patience to work.
