XERF RF Skin Tightening

What is XERF?

XERF is powered by dual-frequency monopolar radiofrequency (RF) technology, allowing controlled energy delivery across different skin depths within one treatment session. Unlike conventional RF devices that work at a single level, XERF’s technology enables treatment of the shallow, mid, and deeper dermal layers, supporting more uniform collagen stimulation and structural skin tightening. XERF was jointly developed by Lutronic and Cynosure—two globally established medical technology companies behind many doctor-grade lasers and energy-based devices used in medical aesthetic clinics worldwide.

How Does XERF Work?

Wave Fit™ Pulse Technology

XERF automatically adjusts each RF pulse based on how much energy the skin absorbs.

Ensures every pulse is effective yet gentle

Delivers controlled heat to reach the collagen-stimulating range

Prevents overheating while optimising collagen contraction and regeneration

Multi-Depth, Precision Energy Delivery

With three treatment depths—Shallow, Middle, and Deep—and 10 adjustable energy levels, XERF allows treatments to be customised based on skin condition and treatment goals.

Enables even, layered heating across different dermal levels

Supports comprehensive collagen remodelling in a single session

Smart GUI simplifies expert-level settings for consistent, high-quality results

Real-Time Impedance Monitoring

Before and during treatment, XERF analyses the skin’s electrical resistance to fine-tune energy delivery.

Adapts energy output based on skin hydration, thickness, and density

Ensures optimal energy penetration and consistent heating

Enhances accuracy, safety, and treatment consistency across different skin types

Surface Temperature Monitoring for Safety

XERF continuously monitors skin surface temperature throughout treatment.

Maintains surface temperature within a safe range

Automatically pauses RF delivery if the temperature exceeds 43°C

Helps prevent burns or thermal injury

Why This Matters

These integrated smart technologies allow XERF to deliver high-energy RF across multiple skin layers with minimal risk, making it a non-invasive, comfortable RF treatment option with no downtime.

Benefits of XERF

Dual-frequency RF. Multi-depth tightening. Natural results.

Deep Collagen Stimulation

Targets superficial to deep dermal layers in a single treatment for comprehensive collagen remodelling.

Structural skin tightening

Improves firmness, elasticity, and skin density by strengthening the skin’s support from within.

Comfort-First Cooling Technology

An integrated 3-level ICD Cooling System dynamically adjusts cooling based on treatment intensity, maintaining surface temperature and significantly reducing discomfort—without the need for pre-treatment numbing.

Non-invasive, no downtime

Comfortable treatment with gradual, natural-looking lifting—no injections or recovery needed.

What Areas Can XERF Target?

Smile lines & nasolabial folds

Cheeks & mid-face

Jawline & jowls

Double Chin

Who is XERF suitable for?

XERF is suitable for both men and women who are experiencing mild to moderate skin laxity and are seeking a non-invasive approach to improve skin firmness and structural support.

It may be suitable for individuals who:

Notice sagging, loosening, or loss of skin elasticity

Feel their skin has become less firm or supported over time

Prefer treatments without injections, incisions, or downtime

Want gradual, natural-looking improvements in skin quality

XERF is commonly chosen by men and women in their 30s to 50s, or by those looking to maintain results from other aesthetic or collagen-stimulating treatments.

When can I expect to see results

Some individuals may notice subtle firmness shortly after treatment as collagen fibres begin to contract.

However, XERF works by stimulating your skin’s natural collagen and elastin production, which takes time.

Typical timeline:
Immediate: Mild tightening or improved skin feel may be noticed
4–6 weeks: Gradual improvements in firmness and skin texture
2–3 months: More visible tightening and improved elasticity as new collagen forms
Up to 6 months: Results continue to improve over time
Results develop progressively and naturally, without sudden or artificial-looking changes.

FAQ’s

XERF is an approved medical device by the Korean MFDS (Ministry of Food and Drug Safety), ensuring its safety.

The number of sessions depends on your skin condition, degree of laxity, and treatment goals.

Some patients may see noticeable improvement after one session, while others may benefit from a series of treatments for optimal and longer-lasting results. Your doctor will advise a personalised treatment plan during consultation.

XERF is a zero-downtime treatment that delivers energy to the skin. You can normally resume your daily activities immediately after the treatment without any recovery period.

XERF uses multiple automated technologies to reduce pain.The ICD Cooling System lowers the skin temperature directly at the treatment spot, and the built-in Wave Fit Pulse technology monitors and stabilizes the overall treatment to ensure you receive the right balance of energy delivery and cooling effect.

XERF is a non-invasive medical device, so no special care is required after the treatment. You can even wear makeup on the same day.
