Pmise QE-02

The Pmise QE-02 is an EO Q-switched Nd:YAG laser built for professional tattoo removal and the treatment of benign pigmented lesions. It uses electro-optic Q-switch technology to release light in extremely short, high peak-energy pulses, which is the core requirement for breaking down ink and melanin particles safely inside the skin.

The system delivers two working wavelengths from a single platform. The deeper-penetrating beam reaches pigment in the dermis, while the shorter wavelength targets superficial marks closer to the skin surface. Operators switch settings from an LCD touch interface and choose from a continuously adjustable spot range, so the same device covers a wide span of indications and skin presentations. It belongs to our EO Q-Switched Nd:YAG Laser line.

This is professional equipment intended for use by trained clinicians in clinics and aesthetic centers. For a deeper comparison of the technology behind it, see our guide on EO Q-switched vs standard Nd:YAG.

The QE-02 works on the principle of selective photothermolysis, first described by Anderson and Parrish in 1983. The idea is that a pulse of light matched to a target's absorption, and shorter than the target's thermal relaxation time, deposits energy into that target before heat spreads to surrounding tissue. This is what allows pigment to be destroyed while the skin around it is largely spared.

Because tattoo ink and melanin clusters are very small, they cool in nanoseconds. To act on them selectively, the laser must fire in nanosecond-scale pulses. Electro-optic (EO) Q-switching is used to compress the laser output into these ultra-short, high peak-energy bursts. When the pulse is absorbed by a pigment particle, the rapid energy deposition produces a photoacoustic effect that shatters the particle into tiny fragments. Some fragments are expelled from the skin surface, and the rest are small enough to be engulfed by phagocytes and cleared through the lymphatic system over the following weeks.

Wavelength choice drives depth and target. The longer wavelength penetrates deeper and is well suited to dark, deep pigment and darker skin types, while the shorter wavelength is absorbed more strongly by superficial pigment such as freckles and lentigines. Having both available lets the operator match the beam to the lesion rather than force one setting onto every case.

The QE-02 suits clinics, dermatology practices and distributors serving providers who treat pigment and tattoos. Common applications include:

• Multi-color tattoo removal, including black, blue, brown and red inks
• Benign pigmented lesions such as sunspots, age spots, freckles and cafe-au-lait macules (CALMs)
• Dermal pigment conditions including nevus of Ota and zygomatic lesions
• Melasma management as part of a cautious, professionally supervised protocol
• Laser facial and skin rejuvenation, helping to refine skin tone and soften the look of fine lines

Suitability and settings depend on the individual's skin type and the depth of pigment, so a trained operator should assess each case. See related tattoo removal solutions and our pigmentation treatment solutions.

• Dual working wavelengths on one platform, so a single device covers both superficial and deeper pigment targets
• EO Q-switch design that produces stable, high peak-energy nanosecond pulses for consistent, repeatable results
• Continuously adjustable spot size, giving operators fine control over fluence across different lesions and skin types
• LCD touch interface for straightforward parameter selection and a smooth clinic workflow
• Articulated arm beam delivery for accurate, flexible handpiece positioning during treatment
• Robust build intended for daily professional use, backed by manufacturer training and support

Which tattoo colors and pigment conditions does the QE-02 treat?

It is designed for multi-color tattoos, including black, blue, brown and red inks, and for a range of benign pigmented lesions such as sunspots, age spots, freckles, nevus of Ota and cafe-au-lait macules. The dual wavelengths let the operator match the beam to the depth and color of the target. A trained clinician should confirm suitability before any session.

Is it safe for darker skin types?

The deeper-penetrating wavelength is generally preferred for darker skin because it interacts less with surface melanin, which lowers the risk to the epidermis. Even so, outcomes depend on correct settings, spot size and cooling, and on a careful assessment of each person's skin type. This is professional equipment and must be operated by trained staff following a tested protocol.

How many sessions are usually needed?

Pigment and tattoo clearance is gradual because the body clears shattered particles through the lymphatic system between visits. Most cases require several sessions spaced weeks apart, and the exact number varies with ink density, pigment depth and individual response. Providers should set realistic expectations and space treatments to allow the skin to recover.

What training and support come with the device?

Pmise supplies operating documentation and operator training so clinical staff can run safe, effective protocols, along with after-sales technical support and warranty coverage. Because this is a professional laser, we recommend that only trained operators use it and that clinics follow local regulations for laser treatment.
