Laser tattoo removal is a crucial procedure that people who regret getting a tattoo look for. It has evolved over the years and there is always new technology to make the process more efficient but what are the differences between the different types of lasers?
The use of picosecond technology is a new and advanced technique that is known to have great results in fewer sessions than other lasers. It has ultra-short pulses that destroy the ink particles in tiny pieces without damaging the surrounding tissue. The particles will be then naturally absorbed and eliminated by the body. They work for most colors of ink and skin.
There are also Q-Switched lasers, which are the most used lasers for tattoo removal. They have subcategories that will vary according to the type of ink or situations.
The Q-switched ruby laser will be most effective in the removal of black, blue and green tattoos and is very powerful, so should be used with care as it could cause skin discoloration and create blotches. The alexandrite laser is the weakest of Q-switched lasers. It works only on darker ink colors and is safer for people with darker skin, as it will reduce the chances of unwanted marks.
The Q-switched Nd: YAG laser is also a great option for darker skin colors, as it uses near-infrared light. It attacks a great range of colors and is less likely to cause pigmentation and textural changes to the skin surrounding the tattoo.
A reliable professional will indicate the right laser to use and will do the procedure with minimal pain so you can enjoy your skin again.
