PicoWay is an excellent laser that we use in our NYC practice for tattoo removal. In my opinion, it can treat tattoos with less follow up visits in comparison to other lasers. What separates PicoWay from other methods of tattoo removal is that this laser uses photo acoustic energy as opposed to thermal energy. Therefore, this laser shatters the tattoo particles into much smaller fragments. Depending on the tattoo, it is required to have a series of treatments (4-5 sessions) in order to see optimal results, with 1 month space between each session. When considering tattoo removal, it is important to seek consultation from a skilled, board certified dermatologist. Thank you for your question, best of luck!
