Pmise QN-07

The QN-07 is a Q-switched Nd:YAG laser built for professional pigment and tattoo work in clinics and aesthetic studios. It delivers laser light in extremely short nanosecond pulses, which lets trained operators break down unwanted pigment in the skin while limiting heat spread to the surrounding tissue. The system runs at two wavelengths, so a single platform can address both deep and surface pigment targets.

It sits within our Q-Switched Nd:YAG Laser line and is aimed at buyers who want a versatile pigment device: distributors serving skin clinics, and operators who treat tattoos, sunspots, and dermal pigment lesions as part of daily practice. For a deeper look at how this class of device handles ink, see our guide on the Q-switched tattoo removal machine.

The QN-07 pairs a top-homogeneous beam profile with square spot options, a touch-screen interface, and integrated cooling for a predictable workflow. It is professional equipment for trained clinicians, not a home device.

The QN-07 works on the principle of selective photothermolysis, first described by Anderson and Parrish in 1983. The idea is simple: a laser pulse shorter than the time pigment needs to shed its heat will concentrate energy in the pigment particle itself, shattering it without cooking the skin around it. The Q-switch inside the QN-07 compresses laser energy into a nanosecond burst with very high peak power, which is what makes this selective, targeted action possible.

Once the pulse is absorbed, the particle undergoes a rapid photomechanical blast and fragments into tiny pieces. Some are expelled toward the surface, while the rest are small enough for the body's phagocytes to clear through the lymphatic system over the following weeks.

Wavelength choice is the other half of the story. Longer wavelength light penetrates deeper into the skin and is well suited to deep dermal pigment and dark ink, while the shorter, frequency-doubled wavelength stays more superficial and is absorbed strongly by red and warmer-colored targets. Giving the operator both wavelengths on one machine means the QN-07 can be matched to the depth and color of each lesion. A homogeneous, flat beam profile spreads energy evenly across the spot rather than peaking in the center, which helps reduce hot spots and unwanted epidermal injury during treatment.

The QN-07 is designed for pigment-focused aesthetic and dermatologic practice, covering ink removal, benign pigmented lesions, and general skin brightening work. Typical applications include:

• Multi-color tattoo removal, including black, blue, brown, and red inks, plus cosmetic tattoo on brow and eyeline
• Epidermal pigmented lesions such as sunspots, age spots, and freckles
• Dermal and mixed pigment conditions such as nevus of Ota and similar lesions, handled by trained operators
• Laser facial and skin rejuvenation work, including a brighter, more even skin tone, refined pores, and softer fine lines

It suits clinics, medical spas, and distributors who want one pigment platform that covers both tattoo and lesion work. Related in-depth material is available in our tattoo removal solution and freckle treatment solution. Treatment suitability, especially for darker skin types and dermal lesions, should always be judged by the treating clinician.

• Dual-wavelength versatility: two wavelengths on one platform let operators match energy to lesion depth and color, from deep dermal pigment to superficial red targets.
• Top-homogeneous beam: a flat, even beam profile spreads energy across the spot instead of peaking in the middle, which helps protect the epidermis and gives more consistent results.
• Short nanosecond pulsing: the Q-switch produces very short, high-peak-power pulses that favor photomechanical pigment breakup over diffuse heating, reducing thermal load on nearby skin.
• Square spot options: defined square spot sizes support even coverage and precise placement across larger and smaller treatment zones.
• Operator-friendly workflow: a large touch-screen interface and integrated cooling support long working sessions and repeatable settings.
• Reliable, serviceable build: a proven Nd:YAG design intended for daily clinical use, backed by manufacturer support and training.

What can the QN-07 treat?

The QN-07 is a Q-switched Nd:YAG laser used for tattoo removal across several ink colors and for benign pigmented lesions such as sunspots, age spots, and freckles. Its two wavelengths also support laser facial and skin rejuvenation work. A treating clinician should confirm that each specific indication and lesion is appropriate before starting a course of treatment.

Is it safe for all skin types?

Q-switched lasers can be used across a range of skin tones, but risk of pigment change is higher in darker skin. Because of this, settings, test spots, and wavelength selection must be judged by a trained operator for each patient. The QN-07 is professional equipment, and safe outcomes depend on correct assessment, conservative parameters, and proper eye protection during every session.

How many sessions are needed?

Pigment and tattoo clearance is gradual, since the body clears shattered particles through the lymphatic system between visits. Most cases need several sessions spaced weeks apart, and the exact number depends on ink type, pigment depth, color, and the individual patient. The treating clinician sets the interval and endpoint. We avoid fixed clearance promises because real results vary from person to person.

What training and support come with the device?

The QN-07 is intended for trained clinical operators. We provide operating documentation and setup guidance, and staff should be trained in laser safety and pigment treatment before clinical use. Warranty and service terms are confirmed at purchase. Contact our team for details on training, spare parts, and after-sales support for your market.
