What internal temperatures are created by the XERF system, and how were they measured?

In in-vivo studies, Cynosure Lutronic measured internal skin temperatures of 50°C, 60°C, and 70°C using ultrasound-guided fiber-optic imaging. Following the XERF treatment, histological analysis confirmed collagen remodelling.

How do you know XERF treatments strengthen collagen and tighten the skin?

Histological evidence from in-vivo porcine studies shows increased thickening and tightening of collagen bundles at multiple tissue depths, along with an observable upward pull in the fascia.

How do you know how deeply the XERF system delivers RF energy?

Histological analysis from multiple clinical studies confirms the XERF system delivers RF energy to the SMAS (Superficial Musculoaponeurotic System). The SMAS is a foundational tissue layer beneath the skin that plays a key role in lifting and tightening sagging skin and reducing the appearance of jowls.

Can RF skin tightening be safely performed post-facelift?

While there is no universally agreed-upon timeline, many practitioners recommend waiting between two to six months after facelift surgery before undergoing energy-based skin tightening. This guidance is largely anecdotal and varies depending on individual healing and the specific procedure performed.

What is the downtime after a XERF treatment?

Some patients may notice mild redness or swelling immediately after treatment, but these effects typically subside within 24 hours.

How to maintain results after XERF treatment

To prolong benefits, maintain a consistent skincare routine and prioritise sun protection (daily broad-spectrum sunscreen), avoid harsh or irritating products, and support overall skin health with a balanced lifestyle. Optimal outcomes may require a series of sessions with periodic maintenance. Depending on skin type and treatment plan, results may last from several weeks up to three years. For enhanced and longer-lasting outcomes, XERF can be combined with other non-invasive procedures to improve tone, texture, and radiance.

Who is a good candidate for XERF RF skin tightening?

You may be a suitable candidate if you have mild to moderate skin laxity (e.g., lower face or cheeks), prefer a non-surgical option with minimal downtime, can tolerate a comfortable treatment that may feel like gentle tingling or vibration, or are recovering from a facelift and wish to enhance or maintain results.

XERF RF lifting vs other RF devices – 3 key differences

Dual-frequency technology (6.78 MHz + 2 MHz) reaches multiple skin layers to promote deeper, more effective collagen remodelling. Advanced cooling system delivers up to 12 cooling bursts per shot, enabling higher energy while helping protect skin and maintain comfort. Larger treatment tip (6 cm² vs ~4 cm² standard) covers more area per shot, reducing pulses required and shortening session time.

Non-ablative resurfacing, redefined

The Mosaic 3D device redefines non-ablative fractional resurfacing with its advanced 1550nm wavelength, designed to revitalize and brighten the skin. It combines both air-cooled rolling and sapphire-tip stamping in one versatile, effective platform. With integrated cooling and customizable energy delivery, the Mosaic 3D system allows providers to safely and effectively treat sensitive areas around the eyes and mouth, as well as the entire face and body. These unique features help minimize patient discomfort, erythema, and edema while enhancing treatment efficacy and safety. 3D Controlled Chaos Technology™ (3D CCT) introduces a new dimension to our patented CCT scanning, enabling you to take resurfacing to the next level.

How it works

The Mosaic 3D integrated cooling system enables providers to safely and effectively treat sensitive areas around the eyes and mouth. Cooled air flows through the handpiece and onto the unique cold-compression sapphire tips, which simultaneously cool and compress the skin. This helps reduce pain, erythema, and edema, while enhancing treatment efficacy, safety, and patient comfort. 3D Controlled Chaos Technology (3D CCT) optimizes the distribution and depth of multi-level microbeams, and reduces the risk of bulk thermal heating, allowing for increased treatment coagulation volume per stamp without compromising safety. The Mosaic 3D system also measures and tracks energy delivery, giving providers greater insight and confidence in the quality of each treatment.

Key benefits

• High-quality textural improvement around the eyes and mouth

• 3D CCT effectively stimulates mid-dermal collagen and elastin

• Cold-compression sapphire tips for patient comfort

• Boost ROI and differentiate your practice by offering comprehensive fractional resurfacing

• Elevated results with reduced downtime

FAQs

Is numbing cream required, and how long is a typical face treatment? Is numbing cream required, and how long is a typical face treatment?

Yes, numbing cream is recommended for most treatments. Typical Mosaic 3D facial sessions range from 20 to 35 minutes.

How would you characterize the treatment experience and recovery period? How would you characterize the treatment experience and recovery period?

Patients describe the Mosaic 3D treatment as tolerable, often rating it a 3 or 4 out of 10 in discomfort. The integrated cold airflow helps maintain comfort during the procedure. Recovery typically lasts 2 to 5 days. Mild redness and swelling may occur for up to 48 hours, followed by several days of dry skin as the fractional resurfacing process initiates surface renewal.

How many treatments are required to achieve optimal skin revitalization? How many treatments are required to achieve optimal skin revitalization?

A series of 2 to 4 treatments is usually recommended, depending on your skin condition and goals. You and your provider will determine the best plan to meet your skin revitalization needs.

How are air-cooled rolling and stamping technologies combined during treatment? How are air-cooled rolling and stamping technologies combined during treatment?

Mosaic 3D uniquely combines these capabilities in one platform so patients can benefit from highly effective cold compression sapphire tips ideally suited for treating around the eyes and mouth, while the efficient rolling technique rapidly and consistently helps to fractionally treat tone and textural concerns across the entire face. This combination enables providers to effectively address multiple skin revitalization concerns at one time.
