Pmise QN-12

The Pmise QN-12 is a Q-switched Nd:YAG laser built for professional pigment and tattoo work in clinics and aesthetic centers. It delivers light in ultra-short nanosecond pulses at two wavelengths, so a single platform can address both deep blue-black pigment and surface-level red ink. The system belongs to Pmise's Q-Switched Nd:YAG Laser line.

Clinics reach for the QN-12 when they need controlled, targeted removal of unwanted pigment without heavy thermal load on the surrounding skin. Typical uses include tattoo removal, sun and age spots, and laser facial toning. It is professional equipment intended for trained operators working within their local scope of practice.

For a deeper look at how Q-switched platforms handle ink, see our guide to the Q-switched tattoo removal machine and the wider tattoo removal solution.

The QN-12 works on the principle of selective photothermolysis, first described by Anderson and Parrish in 1983. The idea is simple: match the laser wavelength and pulse duration to the target so that pigment absorbs the energy while nearby tissue is largely spared.

Each pulse lasts only nanoseconds. In that instant the light is absorbed by pigment particles and ink, producing a rapid photoacoustic effect that shatters them into tiny fragments. Some fragments lift away from the skin surface; the rest are small enough for the body's phagocytes to engulf and clear through the lymphatic system over the following weeks.

Two wavelengths give the operator range. The 1064 nm beam penetrates more deeply and is suited to blue, black and green-blue pigment, while the 532 nm beam sits closer to the surface and is better absorbed by red tones. Longer wavelengths reach deeper skin layers, which is why the dual-wavelength design lets one device treat pigment at different depths. A homogeneous, top-hat style beam profile helps spread energy evenly across the spot instead of peaking in the center, which supports more predictable results and helps limit unnecessary stress on the epidermis.

The QN-12 suits clinics, medical spas and distributors serving pigment and tattoo removal demand. Common applications include:

• Tattoos in black, blue, green-blue, brown, coffee and red tones, including cosmetic eyeliner and eyebrow tattoos
• Pigmented lesions such as sunspots, age spots, freckles and certain nevi
• Dermal pigment conditions including Nevus of Ota, chloasma-type hyperpigmentation and cafe-au-lait marks, handled by experienced operators
• Laser facial toning for a brighter, more even complexion, finer lines and refined pores

Suitability depends on skin type, lesion depth and pigment color, so a professional assessment before treatment is essential. It is not intended for home use.

• Dual 1064 nm and 532 nm output, so one platform covers both deep and surface pigment as well as multi-color ink
• Homogeneous top-hat beam profile that distributes energy evenly and helps avoid excessive epidermal damage compared with a peaked Gaussian beam
• Ultra-short nanosecond pulsing that concentrates the photoacoustic effect on pigment while limiting heat spread to surrounding tissue
• Selectable square spot sizes for precise coverage on both broad areas and detailed work
• Large touch-screen interface for straightforward parameter setting and a smoother clinical workflow
• Nd:YAG solid-state source chosen for stable, repeatable output across a busy treatment schedule

What can the QN-12 treat?

It is used mainly for tattoo removal and pigmented concerns such as sunspots, age spots, freckles and certain dermal pigment conditions, plus laser facial toning. The 1064 nm wavelength targets deeper blue-black pigment and the 532 nm wavelength addresses red and surface tones. A trained operator should assess each case first, since results depend on pigment color, depth and skin type.

Is it suitable for all skin types?

Q-switched Nd:YAG lasers are generally considered flexible across a range of skin tones because the 1064 nm wavelength is less absorbed by surface melanin. That said, settings must be tailored to the individual, and darker or reactive skin calls for extra caution. A patch test and professional consultation help reduce the risk of unwanted pigment change.

How many sessions are needed?

Pigment and tattoos usually clear gradually over several sessions rather than in one visit, because the body needs time to carry away the shattered particles through the lymphatic system. The exact number varies with ink density, color, depth and how the skin responds. Your provider can give a realistic estimate after examining the area.

Do operators need training, and what about warranty?

Yes. The QN-12 is professional equipment and should only be operated by trained staff following proper safety and eye-protection practice. Pmise provides operating guidance and after-sales support; specific warranty terms and training arrangements are confirmed at the time of purchase. Please contact us for details for your market.
