PIQO4​™ for Melasma & Tattoo Removal

The Eraser

The PiQo4™ is a revolutionary laser that offers a new approach to removing tattoos, pigmentation and provides comprehensive skin toning and rejuvenation based on photoacoustic energy. The PiQo4™ is the only 4 wavelength treatment to use both Pico & Nano energies to remove undesirable pigments.

Unlike other lasers, the PiQo4™ does not use heat. Instead, it uses acoustic energy for neocollagenasis (the process of making more collagen). Since heat is not the primary source of energy, it is safer to use on all skin types, including darker skin tones which are traditionally more difficult to treat due to the high rate of rebound with post inflammatory hypopigmentation.

What it treats?

  • Melasma
  • Birthmarks
  • Sun damage and brown spots
  • Fine lines and wrinkles
  • Tattoos
  • Freckles
  • Hyperpigmentation and scarring
  •  General skin tone and texture


Breaking down the new technology:

Clinical studies have shown that the optimal method for shattering pigment particles is to treat them with both Nano and Picosecond laser pulses. First, the Nanosecond pulses are used to deliver short bursts of energy that break down the larger and deeper pigment or ink particles. Then, the area is rescanned with Picosecond pulses that dismantle the smaller and shallower particles. This combination yields far better results than using either one of the technologies on its own.


With this incredible technology the PiQo4™ can erase multiple colors at varying depths in the same session with a single laser. This means easier, safer pigment removal sessions, and fewer total sessions needed by each patient. This allows for better color
clearance and faster results.
