XERF™ (eXperience Exponential RF) is a non-invasive treatment using a dual-frequency monopolar radiofrequency (RF) platform engineered for structural skin tightening, skin firmness, and deep collagen stimulation without surgery, needles, or downtime.
What is XERF?
It is a non-invasive treatment that utilises dual-frequency monopolar radiofrequency (RF) technology to achieve structural skin tightening and deep collagen stimulation. By delivering targeted heat to multiple layers of the skin, including the SMAS, it promotes immediate contraction and long-term firming without surgery, needles, or downtime. Designed for comfort, the system incorporates integrated cooling technology that eliminates the need for anaesthesia, making it a highly efficient solution for addressing skin laxity in areas such as the lower face, jawline, and neck.
How does XERF work?
It combines 6.78 MHz and 2 MHz frequencies and delivers deep into tissue layers that traditional single-frequency systems struggle to reach simultaneously. The 6.78 MHz frequency targets the upper and mid-dermis to contract existing fibres, while the deeper 2 MHz frequency penetrates to the fibrous septa and SMAS layer, heating tissue to the optimal 55-65°C range required to trigger fibroblast activation and long-term neocollagenesis.
Integrated Wave Fit™ technology dynamically adjusts pulse delivery based on real-time skin impedance, while Integrated Cryogen Delivery (ICD) rapidly cools the epidermis before, during, and after each energy burst. This multi-depth bulk heating creates immediate structural tightening through collagen contraction, followed by progressive firming, lifting, and elastogenesis over 2 to 6 months — all while completely preserving epidermal integrity to eliminate downtime and the need for anaesthesia.

Treatment times, associated pain, and downtime.
This treatment takes approximately 30 to 45 minutes, depending on the areas treated.
You may experience a brief cold spray followed by a deep, manageable warming sensation as energy is delivered into the skin during the treatment. The Wave Fit™ technology also adjusts RF pulse delivery in real time based on local tissue impedance, preventing sharp thermal spikes or "hot spots" that typically cause pain.
There can be signs of mild flush or minor, subtle swelling in sensitive areas immediately post-treatment. These resolve naturally within 24 hours. Patients can apply skincare, sunscreen, and makeup immediately after treatment and return to work or social events.

FAQs
XERF radiofrequency skin tightening provides a dual-phase response, starting with subtle, immediate firmness caused by thermal contraction of existing collagen fibres on day one. True structural remodelling begins over the following weeks as fibroblasts synthesise new collagen and elastin, with visible lifting, reduced laxity, and enhanced dermal density becoming clearly noticeable between weeks 4 and 12. These results reach their peak stabilisation at 3 to 6 months and typically persist for 12 to 24 months.
Most patients require 1 to 2 treatment sessions for optimal results, depending on baseline dermal laxity and structural goals. While a single treatment effectively restores firmness for mild to moderate skin looseness, moderate to severe laxity typically benefits from 2 sessions spaced 3 to 4 months apart to build sufficient collagen density. To maintain long-term structural lifting and counteract natural aging, a single touch-up session is generally recommended every 12 to 18 months.
While Thermage relies on single-frequency monopolar radiofrequency for deep volumetric heating and Ultherapy uses micro-focused ultrasound to reach the deep SMAS layer for structural lifting, XERF incorporates dual-frequency monopolar radiofrequency (6.78 MHz and 2 MHz) to treat multiple dermal depths simultaneously. This dual-action approach focuses on surface tightening, collagen density, and fine-line remodelling while distributing thermal energy more evenly, delivering comparable volumetric firming with significantly less treatment discomfort than single-pulse radiofrequency or targeted ultrasound platforms.
When combined with deep-focused ultrasound like Ultherapy, XERF tightens the upper dermis while ultrasound anchors the underlying SMAS layer; when paired with skin boosters, polynucleotides, or oxygenating facials, the deep thermal stimulation is bolstered by cellular repair and intense hydration. It can also be integrated with hyaluronic acid fillers or neurotoxins to restore lost structural volume and relax dynamic wrinkles, provided heat-generating treatments are performed either before injectables on the same day.
Patients should immediately prioritise gentle hydration with non-comedogenic, barrier-repairing moisturisers while avoiding harsh active ingredients such as retinoids, AHAs/BHAs, and vitamin C for 3 to 5 days. Daily application of a broad-spectrum physical sunscreen is essential to shield newly remodelling tissue from photodamage, and to avoid direct heat exposure, strenuous exercise, saunas, and hot baths for 24 to 48 hours to minimise excessive erythema or swelling.
Not suitable for:
- Individuals with pacemakers, ICDs, or neurostimulators, as RF energy can cause electromagnetic interference.
- Pregnant or breastfeeding mothers
- Active skin conditions such as open wounds, active acne, herpes simplex outbreaks, severe rosacea, or active skin infections.
- Active immunological disease
Risks
Common post-treatment responses include temporary redness, mild swelling, warmth, and skin tenderness, which typically resolve within 24 to 48 hours. Less common risks include prolonged swelling, bruising, or transient skin dryness, whereas rare clinical complications (often linked to improper energy delivery) include thermal burns, blistering, post-inflammatory hyperpigmentation, or surface contour irregularities such as localised fat atrophy.
