What is Dual-Frequency Monopolar RF (XERF)?
FDA-cleared, non-invasive procedure using dual-frequency monopolar radiofrequency, performed exclusively by our doctor at Alluna Medical n Hong Kong
Redefine Your Skin with Confidence
Dual-frequency monopolar radiofrequency, or XERF, is a non-invasive, energy-based treatment used to support skin tightening and improvement in the appearance of skin laxity in suitable patients. By delivering radiofrequency energy into the skin, it is intended to support collagen remodeling over time. Individual responses vary, and outcomes, comfort, downtime, and duration of effect differ between patients.
At Alluna Medical, XERF is performed by our doctor with direct medical assessment, treatment planning, and oversight. The device used in our clinic is US FDA-cleared for specific indications; your suitability and expected outcomes will be discussed during consultation.
What is XERF?
XERF is an energy-based treatment that delivers monopolar radiofrequency energy into targeted layers of the skin. This energy is intended to stimulate collagen remodeling, which may gradually improve the appearance of skin firmness and laxity over time.
Unlike treatments that act only on the surface, XERF is designed to act on deeper layers within the skin’s support structures, with changes that may develop progressively and differ between individuals.
💡 XERF protocols at Alluna Medical are adjusted with care to take into account different skin types, including Asian skin, with the aim of reducing treatment-related risks where possible. Suitability for XERF is determined after medical assessment.

Doctor-performed procedure – treatment is carried out by our doctor, typically across the agreed face and/or neck areas, using a defined number of shots based on the plan.

Results
Any changes from XERF typically appear gradually as collagen remodeling occurs over time. Patients may start to notice differences in the treated areas over the following weeks to months.
The degree and duration of improvement vary between individuals and depend on factors such as skin condition, age, treatment parameters, and lifestyle. Maintenance or additional treatments may be discussed as part of your ongoing plan.
Frequently Asked Questions
Is XERF suitable for Asian skin?
Suitability depends on individual skin type and medical assessment. At Alluna Medical, our doctor adjusts treatment depth and energy settings with the aim of reducing risk, including the risk of post-inflammatory pigmentation, where possible.
How long do results last?
The duration of any improvement varies between individuals. Some patients may notice changes for many months, but this depends on factors such as age, skin quality, treatment settings, and lifestyle. Expected duration and maintenance options will be discussed during consultation.
Who is a suitable candidate?
XERF is generally considered for patients with mild to moderate skin laxity, for example around the jawline, lower face, or neck, who are seeking a non-surgical option. It is not a replacement for surgical lifting procedures. Suitability is determined after a medical assessment.
Does it hurt? What is the downtime?
Patients may feel warmth, heat, or tingling during treatment. Discomfort is usually tolerable for most individuals, and the device’s cooling features are intended to improve comfort. Many patients are able to resume usual daily activities shortly after treatment, although some temporary redness or swelling can occur.
Why choose a doctor instead of a therapist for XERF?
A doctor can take into account your medical history, anatomy, and treatment goals when selecting energy depth and dosage. This supports appropriate patient selection, treatment planning, and technique.
Is XERF FDA-cleared?
The XERF device used at Alluna Medical is US FDA-cleared for specific indications. FDA clearance relates to the device and its approved indications, and does not guarantee particular cosmetic outcomes for every patient.
Treatment Pricing
At Alluna Medical, XERF treatments are performed by a doctor, with direct medical oversight and individualized treatment planning. Treatment scope, session length, and pricing depend on the areas treated and the agreed treatment plan.
Pricing and recommended treatment options will be discussed with you during consultation before any procedure is performed.
