Lutronic Xerf™
Dual-Frequency Monopolar RF
The world's first multifrequency monopolar radiofrequency system — delivering deep structural skin tightening from the dermis to the SMAS layer, with zero downtime and no numbing required.
The Technology
A New Paradigm in
Structural Skin Tightening
For years, energy-based skin tightening faced a persistent trade-off: achieving meaningful lift required invasive procedures, needles, or high thermal pain. Lutronic Xerf™ fundamentally redefines this paradigm as the world's first multifrequency monopolar radiofrequency system — simultaneously delivering two distinct RF energy channels to treat every layer of the skin in a single pass.
At Laser Center of Southlake, Santa Burkhart is the first practitioner in North Texas to introduce Lutronic Xerf™ — and was selected by Lutronic to conduct official medical studies evaluating Xerf's specialized periorbital and eye-tightening protocols, actively shaping the future of non-invasive eye rejuvenation.

How It Works
The Physics of Dual-Frequency Monopolar RF
Unlike conventional single-frequency devices, Xerf operates by simultaneously emitting two distinct radiofrequency energy channels — treating every structural layer of the skin in a single pass.
6.78 MHz
Superficial to Mid-Dermis
Contracts existing collagen networks and triggers the synthesis of fresh collagen and elastin in the upper dermal layers.
2.0 MHz
Subcutaneous Tissue & SMAS Layer
Penetrates deep into the SMAS — the foundational structural layer traditionally repositioned during a surgical facelift — for true structural lifting without surgery.
Patient-Centric Design
Never-Numb™ Comfort & Zero Downtime
Xerf's Wave Fit™ pulse technology delivers energy through smooth micro-pulses accompanied by Integrated Cryogen Delivery (ICD) surface cooling. The epidermis remains cool and protected throughout, eliminating the need for topical numbing creams. Xerf's Accurate Impedance Feedback system measures skin density in real time, auto-adjusting energy parameters for every single pulse.
Signature Protocol
The K-Luxe Treatment Xerf + Lutronic Ultra MD
Recognizing that true skin youthfulness requires structural support beneath the surface and clarity on top, Santa Burkhart developed the K-Luxe Treatment — a dual-action protocol inspired by advanced aesthetic protocols from South Korea that combines deep structural tightening with surface-level resurfacing in a single session.
Lutronic Xerf™
Deep Structural Tightening
Santa uses Xerf to treat the lower face, jawline, cheekbones, and neck. The dual-frequency monopolar RF heats deep tissue layers — including the SMAS — initiating collagen remodeling and tightening the skin matrix from within.
Lutronic Ultra MD™
Surface Resurfacing & Luminosity
Immediately following Xerf, Santa applies the Ultra MD 1927nm thulium fractional laser. The micro-channels created by Ultra MD clear superficial pigment, boost skin hydration, and leave a radiant, smooth finish. Thermal priming from Xerf improves tissue receptivity for Ultra MD laser energy.
Clinical Benefits of K-Luxe
Clinical Research
Official Lutronic Medical Studies
for Periorbital Eye Treatments
Lutronic designated Santa Burkhart and Laser Center of Southlake as an official clinical research investigator for Xerf periorbital eye treatments. The skin around the eyes is among the thinnest on the body — treating this delicate area non-invasively requires extreme precision to protect surrounding ocular structures. Santa's clinical contributions directly inform global treatment guidelines.
Precision Applicators
Effector 10
Designed for larger periorbital vector passes along the eyebrow arch, temple, and lateral orbital rim to encourage natural brow elevation.
Effector 5
Optimized for targeting delicate rhytids, fine lines around crow's feet, and crepey upper and lower eyelid skin with precision.

Common Questions
Lutronic Xerf FAQs
What makes Lutronic Xerf different from other RF devices?
Xerf is the world's first multifrequency monopolar radiofrequency system, simultaneously delivering 6.78 MHz and 2.0 MHz energy channels. This allows it to treat every structural layer of the skin — from the superficial dermis all the way down to the SMAS layer — in a single pass. No other RF device achieves this depth range without needles or surgery.
Does Xerf require numbing cream?
No. Xerf's Never-Numb™ design uses Wave Fit™ pulse technology with Integrated Cryogen Delivery (ICD) surface cooling to keep the epidermis comfortable throughout treatment. Because the outer skin stays cool and protected, topical numbing creams are not required — unlike RF microneedling or many other energy-based devices.
What is the K-Luxe Treatment?
K-Luxe is Santa Burkhart's signature dual-treatment protocol combining Lutronic Xerf with the Lutronic Ultra MD thulium laser. Step one uses Xerf to tighten deep structural tissue layers. Step two uses Ultra MD to resurface and refine the skin surface — clearing pigment, boosting hydration, and restoring luminosity. Both treatments are performed in a single session for complete rejuvenation.
Can Xerf treat the area around the eyes?
Yes — and this is one of Xerf's most exciting capabilities. Santa Burkhart is an official Lutronic clinical research investigator for Xerf periorbital eye protocols. Using specialized Effector 5 and Effector 10 micro-applicators, Xerf can safely tighten upper eyelid laxity, smooth crow's feet, and elevate the lateral brow without surgery or anesthesia.
Is there any downtime after Xerf?
Zero downtime. You may experience mild warmth or faint redness in the treated area for a few hours, but most patients return to normal activities, exercise, or apply makeup immediately after their session. There is no peeling, swelling, or pinpoint bleeding.
