Pmise QN-11

The Pmise QN-11 is a Q-switched Nd:YAG laser platform built for professional pigment and tattoo work in clinics and aesthetic centers. It delivers light in ultra-short nanosecond pulses at two working wavelengths, which lets a trained operator target dark tattoo ink and a wide range of pigmented lesions while keeping surrounding skin comparatively protected.

The system is part of Pmise's Q-Switched Nd:YAG Laser line. Its top-homogeneous beam profile spreads energy more evenly across the treatment spot than a standard Gaussian beam, which helps reduce the risk of hot spots and excess damage to the epidermis. Square spot options give the operator precise, edge-to-edge coverage on defined lesions.

QN-11 is professional equipment intended for use by trained medical or aesthetic operators. Buyers looking at a full tattoo-removal workflow can read our in-depth guide on choosing a Q-switched tattoo removal machine alongside these specifications.

The QN-11 works on the principle of selective photothermolysis, first described by Anderson and Parrish in 1983. The laser emits high peak-power light at a wavelength that is preferentially absorbed by pigment in the skin. Because each pulse lasts only a few nanoseconds, the energy is deposited faster than heat can spread to nearby tissue, so the pigment particle absorbs the shock while the surrounding skin stays relatively cool.

The two wavelengths do different jobs. The 1064nm beam penetrates deeper and is well suited to dark, dermal and endogenous pigment such as nevus and tattoo ink. The 532nm beam is more strongly absorbed by superficial and red-toned pigment, making it useful for surface lesions and colored tattoos. Matching wavelength to the target depth is what makes the technology effective across different indications.

When the pigment absorbs the pulse it heats and fractures in an instant, a photomechanical or light-blasting effect. The particles break into fragments that are too small to be seen. Some are shed through the epidermis and the rest are engulfed by phagocytes and cleared gradually through the lymphatic system over the following weeks. The top-homogeneous beam and short pulse width together aim to break pigment cleanly while limiting the thermal load on the epidermis.

The QN-11 suits clinics, medical spas and distributors serving pigment and tattoo treatment demand. It is operated by trained professionals who select the wavelength, spot size and energy for each case.

• Tattoo removal, including black, blue, brown and red inks, plus tattooed eyeliner and eyebrow
• Pigmented lesions such as sunspots, age spots, freckles and nevus
• Dermal pigment conditions including nevus of Ota and post-inflammatory pigmentation
• Laser facial and skin rejuvenation, including pore refining, fine lines, and support for oil control and overall skin texture

• Top-homogeneous beam that spreads energy evenly across the spot, different from Gaussian and flat-top modes, to help avoid excessive epidermis damage
• Two working wavelengths in one platform, so operators can address both deep and superficial pigment without changing machines
• Square spot options for precise, well-defined coverage on lesions and tattoo edges
• Ultra-short nanosecond pulses that concentrate the effect on pigment and help keep the treatment comfortable
• Touch-screen control for straightforward parameter setting and repeatable clinic workflow

These strengths are aimed at consistent results and a reliable day-to-day workflow rather than headline numbers. Actual outcomes depend on the operator's technique, the indication and the patient's skin.

What can the QN-11 treat?

It is used mainly for tattoo removal and pigmented lesions such as sunspots, age spots, freckles and nevus, and for laser facial and skin rejuvenation. The 1064nm and 532nm wavelengths let a trained operator match the beam to the depth and color of the target. As with any laser, suitability is assessed case by case before treatment.

Is it safe for all skin types?

Q-switched Nd:YAG lasers are generally considered among the more flexible options across skin tones, but no laser is risk-free for every patient. Darker skin types need conservative settings and careful test spots because of the higher risk of pigment change. A qualified operator should evaluate skin type, history and the specific lesion before choosing parameters.

How many sessions are needed?

It varies. Tattoos and stubborn dermal pigment usually need several sessions spaced weeks apart so the lymphatic system can clear the fragmented particles between visits. Some surface lesions respond faster. The operator sets a realistic plan based on ink depth, color, lesion type and how the skin responds to earlier sessions.
