Pmise QN-01

The QN-01 is a Q-switched Nd:YAG laser built for professional pigment and tattoo work in clinics and aesthetic centers. It delivers laser light in very short, high peak-power pulses through two working wavelengths, so a single platform can address both deep and superficial pigment as well as multi-color tattoo ink. It belongs to the wider Q-Switched Nd:YAG Laser family from Pmise.

Buyers looking for a versatile pigment station will find the QN-01 covers the everyday caseload: unwanted tattoos, sun-related spots, dermal pigment such as Nevus of Ota, and light skin-tone refinement. The dual-wavelength design means one device instead of separate tools for red inks and dark inks.

This is professional medical-aesthetic equipment intended to be operated by trained clinicians who follow proper patient assessment, test-spot, and eye-safety procedures.

The QN-01 works on the principle of selective photothermolysis, the idea that a pulse of the right wavelength, short enough in duration, is absorbed mainly by its target and spares the surrounding tissue. Anderson and Parrish set out this framework in 1983, and Q-switched pigment lasers are a direct application of it.

A Q-switch stores energy and then releases it as a pulse lasting only nanoseconds. Because the same energy is packed into such a short time, the peak power is extremely high while the total heat delivered stays low. Pigment particles and tattoo ink absorb this burst, heat up faster than they can spread that heat, and break apart in a rapid photoacoustic action. The fragments are small enough for the body to clear through phagocytes and the lymphatic system over the following weeks.

The two wavelengths do different jobs. The 1064nm beam penetrates deeper and is preferred for dark inks and dermal pigment such as blue, black and green-blue tones. The 532nm beam stays more superficial and is used for red and warm-colored pigment and epidermal spots. A homogenized (top-hat) beam profile is used so energy is spread evenly across the spot rather than peaking in the center, which supports a more uniform result and reduces hot spots. Because the interaction is largely photomechanical rather than thermal, bulk heating of the skin is limited.

The QN-01 suits clinics, dermatology practices and distributors serving pigment and tattoo demand. Typical indications include:

• Multi-color tattoo removal, including black, blue, green-blue, brown and red inks
• Pigmented lesions such as sunspots, age spots, freckles and cafe-au-lait macules (CALMs)
• Dermal pigment conditions including Nevus of Ota and zygomatic pigment
• Melasma, handled cautiously with conservative settings by an experienced operator
• Laser toning for skin rejuvenation, tone evening and a smoother, brighter complexion

See the tattoo removal solution and the melasma solution pages for indication-specific guidance. Suitability, expected number of sessions and skin-type considerations should always be judged case by case during consultation.

• Dual 1064nm and 532nm output so one device covers deep pigment, superficial spots and multi-color ink
• Nanosecond Q-switched pulsing gives high peak power for effective pigment fragmentation with limited heat spread to surrounding skin
• Homogenized top-hat beam supports even energy delivery and helps reduce hot spots
• Adjustable spot size lets the operator match the beam to the lesion and treatment goal
• Built-in energy sensor reports the actual output on the interface for repeatable, controllable sessions
• Articulated arm delivery makes it easier to reach different treatment angles and body areas

What can the QN-01 treat?

It is designed for tattoo removal across multiple ink colors and for pigmented conditions such as sunspots, age spots, freckles, cafe-au-lait macules and dermal pigment like Nevus of Ota. It is also used for laser toning to even skin tone. Final indications depend on the clinician's assessment of each patient during consultation.

Is it safe for all skin types?

Q-switched Nd:YAG systems are used across a range of skin tones, and 1064nm is often preferred for darker skin because it targets pigment while limiting surface heating. Even so, darker and pigment-prone skin needs conservative settings and a test spot. A trained operator should always assess skin type and history before treatment.

How many sessions are needed?

It varies by indication, pigment depth, ink type and the individual. Tattoos and dermal pigment usually need several spaced sessions to let the body clear fragmented particles between visits. The operator sets an interval, typically a few weeks, and reviews progress. We do not promise a fixed result, as outcomes differ per patient.

Do you provide training and warranty?

Yes. The QN-01 is professional equipment meant for trained operators, so we provide operating guidance and application support, plus warranty terms and after-sales service. Contact our team for full warranty details and operator training arrangements for your clinic or distribution market.
