Duet RF™


The Health Canada approved Duet RF™ system was introduced to Canada by SKINLIFE. As a clinical consultant to the manufacturer of the original Duet RF™ system, SKINLIFE saw the potential of the original Duet RF™ and incorporated a number of enhancements to improve the device’s clinical effectiveness and safety. The innovations brought forth by SKINLIFE include features such as a capacitive-return circuitry and a retinal projection thermal imaging system. Duet RF™ at SKINLIFE is a highly popular face and neck contouring treatment. It works by reducing unwanted fat (e.g. jowl fat, submental fat, nasolabial fat) and tightening skin through the use of controlled soft tissue heating generated by radio-frequency energy.



What is Duet RF™?

Duet RF™ is the Health Canada approved, dual function, non-invasive skin treatment device designed to tighten skin, repair scars with minimal to no downtime. Developed with safety, comfort, and effectiveness in mind, the Duet RF™ system embodies state-of-the-art Thermal and Fractional radiofrequency (RF) modes into one single device. On one hand, the Thermal mode utilizes a sophisticated and patented mono-polar RF transmission structure called NTTS to evenly distribute heat energy across the treatment area to tighten sagging skin, smooth out wrinkles, and restore a youthful glow by creating new collagen in the skin. On the other hand, the Fractional mode is powered by patented AFMR electrode arrays to channel energy to multiple, focused zones across treatment area to selectively resurface and rejuvenate scars, sun-damaged skin, and enlarged pores.

Thermal Mode

The Thermal mode is non-ablative and has little to no downtime. The Thermal mode of Duet RF™ is used for tightening of skin and reduction of excessive facial fat. To provide as much comfort as possible, topical and injectable anesthetic is provided as part of the treatment. After the anesthesia, the procedure typically takes about 30 minutes to complete, depending on the area(s) being treated.  In some cases, skin may appear red and slightly swollen, which generally resolves in a few days.

Fractional Mode

The Fractional mode is ablative and falls somewhere between fractional laser (e.g. Fraxel) and fractional radiofrequency (RF) needle (e.g. INFINI™ RF). The Fractional mode of Duet RF™ may deliver energy on skin surface (less deeper than fractional RF needles). As a result, SKINLIFE often combines Duet RF™ with the INFINI™ RF system to target the entire depth of skin when it is necessary (e.g. scar treatments). Used alone, Duet RF™ can still effectively improve scars, enlarged pores, and sun damage on the skin. To provide as much comfort as possible, topical and injectable anesthetics are provided as part of the treatment. The fractional mode of Duet RF™ typically comes with 3 to 7 days of downtime that includes redness, minor swelling, crusting, and peeling as common reactions following the treatment. There will also be some visible scabbing on the treated skin for a few days to 1 week. Any redness and/or swelling will take at least 1 day to resolve. For significant improvement using the Fractional mode of Duet RF™, 3 or more sessions are generally required.

Results & Benefits

Improvements from both the Thermal and Fractional modes may vary depending on the number of sessions repeated, existing skin conditions, and patient expectations. Because the Fractional mode of Duet RF causes the skin to regenerate, and the Thermal mode of Duet RF causes the unwanted excessive fat to self-destruct as the skin builds collagen and elastin in the dermis, results generally take several weeks to become more evident.
