The PiQo4 laser is one of the newest and most powerful lasers on the market today, built almost exclusively for pigment augmentation and tattoo removal. It’s the first high-function 4-Wavelength laser. At Long Island Dermatology, we specialize in a number of laser skin resurfacing procedures. We provide hyperpigmentation removal services as well as tattoo removal with the PiQo4 laser. The PiQo4 laser is the new gold-standard in tattoo removal. The laser works by focusing a powerful beam of energy below the skin’s surface to the dermis, the layer where a tattoo’s ink is placed. The laser energy fades the pigment or ink from within the skin. Causing your tattoo to fade.
