XERF RF Skin Lifting & Tightening Treatment Overview

3 sessions and up

Several months

Minimal to none

15-45 minutes

If you’ve noticed your jawline softening, your cheeks losing their lift, or fine lines settling in despite a diligent skincare routine, you’re seeing the natural decline of collagen that begins from your thirties.

XERF, a Korean radiofrequency (RF) skin lifting and tightening treatment that recently arrived in Singapore, is designed to trigger the deeper response to firm sagging skin with no downtime and needles.

At SL Aesthetic Clinic, our doctors use XERF to lift and tighten the face and neck while ensuring a comfortable experience.

What is XERF?

XERF is a skin-tightening and contouring device developed by Cynosure Lutronic, the global manufacturer behind many clinically proven lasers used in aesthetic clinics worldwide.

It belongs to the family of monopolar radiofrequency devices, the same broad category as RF ThermaLift FLX, but with a key difference: XERF delivers two RF frequencies –6.78 MHz and 2 MHz– at the same time, which older single-frequency RF treatments are unable to do.

By combining frequencies, XERF can deliver heat across multiple depths in a single session, from the upper dermis right down to the deeper fat layers and the SMAS (Superficial Musculoaponeurotic System), the foundational layer that surgeons target in a facelift. This allows for both surface refinement and deep structural lifting in a single treatment, rather than focusing on one layer alone.

How XERF Works

XERF delivers controlled RF energy that gently heats the deeper layers of your skin while protecting the surface. This produces two effects:

Rapid collagen contraction – Existing collagen fibres tighten on contact with controlled heat. You may notice a subtle “lifted” feel in the skin right after treatment.
Long-term collagen remodelling – Heat signals your skin’s repair system to produce fresh collagen and elastin. Over 2–3 months, skin becomes denser, firmer and more defined gradually.

Three Adjustable Depths

Because skin thickness varies across the face, XERF treats at three distinct depths, selected by your doctor for each area:

Depth mode	Targets	Used On
Shallow	Upper dermis	Thinner areas like the forehead; texture & fine lines
Middle	Dermis to superficial fat	Cheeks and neck; moderate firming
Deep	Deep fat / SMAS	Lower face and jowls; structural lifting

How is XERF Different From Ultherapy Prime, RF ThermaLift FLX and HIFU?

	XERF	Ultherapy Prime	RF ThermaLift FLX	HIFU
Energy type	Dual-frequency monopolar RF (6.78 + 2 MHz)	Micro-focused ultrasound with real-time visualisation	Monopolar RF (single)	High-intensity focused ultrasound
Main target	Surface and mid-depth tightening e.g. wrinkles, jowling	Deep tissue lifting and structural support (SMAS layer)	Skin firming e.g. crepey skin, fine lines	Deep tissue lifting and structural support (SMAS layer)
Downtime	Minimal	Minimal	Minimal	Minimal

In short: Ultherapy and HIFU deliver energy as small, focused points to reach deeper layers like fat and muscle, where structural lift is the goal. XERF and other monopolar RF treatments heat the entire treated area continuously at the surface and mid-depth layers, making them well-suited for concerns like fine lines, pores and skin firming.

If you’re dealing with more visible sagging at the brows, cheeks or jawline, your doctor may suggest pairing XERF with a deeper-lift treatment like Ultherapy or HIFU during consultation.

Is XERF Uncomfortable?

No, due to special technologies:

Wave Fit™ Pulse Technology adapts energy delivery to your skin’s resistance in each area, so heating stays even and controlled.
Integrated Cryogen Delivery (ICD) cooling releases multiple cooling bursts with every pulse, protecting the skin surface and reducing the heat sensation – which is why XERF often needs little or no numbing cream.
Real-time impedance monitoring measures your skin’s condition continuously and adjusts the energy delivered, improving both safety and precision.
A larger Spider-Web pattern tip distributes energy evenly and senses contact to reduce the risk of hot spots.

What Makes XERF Different

Several features set XERF apart from earlier RF skin-tightening devices:

Dual-frequency monopolar RF (6.78 MHz + 2 MHz) – Treats multiple layers in one pass, where most RF devices work at a single depth
Three distinct depths combined with around 10 adjustable intensity levels – Highly customisable settings tailored to your skin’s thickness, density and hydration in each area
Four EFFECTOR handpiece sizes – For delicate areas (under-eyes) or broader zones (cheeks, neck)
Pulse-adjustment (Wave Fit™) technology with real-time impedance monitoring – Energy delivery adapts shot by shot for consistent, safe results
Integrated cooling (ICD) that makes the experience comfortable enough to often skip numbing

What XERF Treats

Thanks to its multi-depth delivery, XERF addresses a broad range of facial ageing concerns:

Sagging jawline and jowls — for a sharper, defined lower face
Loose cheeks and nasolabial folds — restoring midface lift
Double chin (submental fullness) — the 2 MHz frequency targets fat while 6.78 MHz tightens
Fine lines and wrinkles — crow’s feet, under-eye lines and lines around the mouth
Crepey, lax skin on the neck and décolletage
Overall skin firmness, density and texture — through collagen and elastin renewal

XERF is best suited to mild to moderate skin laxity — people starting to see early sagging who want a non-surgical option with no recovery time. It is not a replacement for surgical facelifting in cases of severe sagging, and our doctors will tell you honestly if a different approach would serve you better.

Who is a Good Candidate for XERF?

XERF is well-suited if you:

Are in your late 30s to 50s and noticing early laxity
Want a non-surgical lift with no recovery time
Have found HIFU or RF ThermaLift FLX uncomfortable in the past
Are maintaining results from a previous energy treatment

XERF may not be the right fit if you:

Have significant sagging that would benefit more from surgery
Are pregnant or have implanted electronic devices
Have an active skin infection in the treatment area

The XERF treatment experience at SL Aesthetic Clinic

Consultation & facial assessment

Our doctor examines your skin condition and based on their assessment designs a personalised plan, selecting the depths, intensity and treatment areas. Depending on your skin laxity, this may be a single session or a planned course, with periodic maintenance at the right treatment frequency to sustain results.

Preparation

The treatment area is cleansed. XERF is designed to be performed without numbing, but we may apply a topical numbing cream for added comfort where helpful, so treatment can be done at optimal settings.

Treatment

XERF RF energy is delivered in controlled pulses while the integrated cooling mechanism ensures a comfortable experience. You'll feel a warm sensation as energy reaches the deeper layers. Session duration is typically 15-45 minutes depending on the areas treated.

Aftercare

Downtime is minimal; you can return to normal activities and wear makeup immediately. Mild redness usually settles within 1-2 hours.

What Results Can You Expect from XERF RF Skin Tightening?

You can feel tightening and improved skin quality. The more meaningful change builds over the next 2–3 months as new collagen forms – skin looks and feels firmer, contours appear more defined, and fine lines soften. Results typically last around 9–12 months, after which a maintenance session helps sustain the effect.

Because collagen renewal is gradual and individual, results vary with age, skin condition, the number of areas treated and your aftercare. Your doctor sets the right treatment frequency for you – often a single session or a short planned course, followed by periodic maintenance roughly once a year.

Can XERF Be Combined With Other Treatments?

Yes. XERF works well as part of a layered plan, where each treatment targets a different aspect of ageing:

Ultherapy Prime or HIFU – provide the deepest structural lift, which XERF then reinforces at the surface and mid layers
Collagen bio-stimulators (e.g CaHA), and skin boosters (e.g. PN Restore, Korean PN, HTIC Collagen Skinbooster) – improve overall dermal quality and hydration while XERF tightens
Dermal fillers – restore lost volume
Anti Wrinkle Treatment – Softens fine lines and deep wrinkles caused by repeated facial expressions alongside RF tightening

Your doctor will sequence these appropriately so the treatments complement rather than compete.

How Much Does XERF Cost in Singapore?

XERF pricing in Singapore generally depends on the number of areas treated, the number of pulses (shots) delivered, and whether you do a single session or a planned course. At SL Aesthetic Clinic, XERF starts from $2988 per session.

FAQ

What should I avoid after XERF treatment?

Avoid heat exposure –sauna, hot showers and intense exercise– for 24 hours
Avoid alcohol for 24 hours
Keep skin hydrated and use sunscreen daily
Resume your normal skincare; your doctor will flag anything to pause

How many sessions will I need?

Many patients see meaningful improvement after a single session, with results building over 2-3 months. Depending on your skin laxity and goals, your doctor may suggest a short course plus maintenance roughly once a year.

Is there any downtime?

No. You can return to daily activities and wear makeup immediately. Mild redness typically fades within 1-2 hours.

Is XERF safe for all skin types?

XERF is generally considered safe across skin types, and real-time impedance monitoring helps tailor energy safely. A consultation confirms suitability and rules out contraindications.

How is XERF different from RF ThermaLift FLX?

Both are monopolar RF, but XERF uses two frequencies (6.78 + 2 MHz) across three depths, allowing it to tighten skin and address deeper fat and structural layers in one session, with cooling that makes it more comfortable.

How long do XERF results last?

Typically around 9-12 months, after which a maintenance session helps preserve firmness. Individual results vary.

Are there any side effects from XERF?

Side effects include redness, swelling, and tenderness post-procedure but these are normal and temporary and should resolve on their own.

How is XERF different from HIFU?

Both stimulate collagen, but through different mechanisms. HIFU uses focused sound energy to create heat at precise depths. XERF uses radiofrequency – electrical energy that heats tissue through resistance. XERF’s dual-frequency design allows it to treat multiple depths in one pass, including skin surface refinement (6.78 MHz) and deeper fat and SMAS layers (2 MHz). Many patients combine both: HIFU for deep structural lift, XERF to reinforce and tighten from mid-depth upward.

Is XERF suitable for Asian skin?

Yes. Unlike some light-based treatments, radiofrequency does not target melanin, so the risk of pigment-related side effects is comparatively low. This is an advantage in Singapore’s skin-type-diverse patient population. Patients with particularly pigment-prone skin should still flag this at consultation.
