Pico lasers are the most advanced technology. I utilize the PiQo4 laser which has 4 Pico wavelengths including the 532 wavelength ideal for red ink. Certain colors respond best to certain wavelengths. The amount of treatments can vary based on several factors such as the location of your tattoo, your skin tone, how sharp the ink is, and how quickly your body eliminates the ink. Even with advanced lasers and multiple wavelengths complete removal is not always possible. I believe that tattoos are removed faster and safer with Pico lasers and there is less risk of scarring. I think it is important not only to seek the best technology but an experienced laser tattoo removal provider.
Thank you for your question. PicoSure™ is one hundred times faster than any other laser on the market, you will require fewer sessions overall in order to achieve your desired results. Even dark blue, green and yes, red inks – which are usually the most difficult to remove – can be effectively cleared with less treatment. Hope this helps! Best, Dr. Katz
