    PiQo4 Laser

    /PEE-koh-four/

    Definition

    A dual-wavelength picosecond laser that delivers ultra-short energy pulses for tattoo removal and skin toning across all ink colors and skin types.

    The PiQo4 is an advanced aesthetic laser manufactured by Lumenis. It operates in both picosecond (trillionths of a second) and nanosecond modes, delivering ultra-short pulses of energy at four wavelengths: 1064nm, 532nm, 585nm, and 650nm. This multi-wavelength capability allows it to treat all ink colors for tattoo removal and a wide range of pigmentation concerns for skin toning — on all skin types.

    Tattoo Removal with PiQo4

    The PiQo4's picosecond pulses shatter ink particles into fragments so small that the body's immune system can flush them out naturally. Unlike older Q-switched lasers that struggle with certain colors, PiQo4's four wavelengths can target black, blue, green, red, yellow, and orange inks effectively.

    Skin Toning with PiQo4

    In toning mode, PiQo4 uses a broad, gentle beam at lower energy levels to break up melanin clusters responsible for sun damage, age spots, melasma, and uneven pigmentation. Treatments take 20–30 minutes with minimal downtime — most clients experience only slight pinkness for a few hours.
