What Is It

Monopolar Radiofrequency That Heats the Deeper Skin

Thermage FLX is a non-invasive device that passes monopolar radiofrequency into the dermis and the layers beneath it. The controlled heat tightens existing collagen straight away and prompts the skin to build new collagen over the months that follow, so firmness and texture improve gradually.

One treatment tip can cover large areas efficiently. The FLX generation added stronger vibration and cooling for comfort, plus an accelerator that speeds up delivery. Thermage FLX is FDA-cleared for non-invasive treatment of the face, eyes and body.

Its action rests on one mechanism: heating the deep dermis. That suits mild to moderate laxity, but it does not replace lost facial volume, change how fat is distributed, or tackle the other aspects of facial ageing that the combined protocols at IN Eternity Clinic are designed to address together.

Key facts
  • What it is: Thermage FLX, a non-invasive monopolar radiofrequency device that heats the deep dermis and subdermal layers while cooling the surface.
  • How it works: heat contracts existing collagen and prompts new collagen to form over the following three to six months.
  • Areas: face and jawline, eyelids (with the Eye Tip), neck, décolletage, abdomen, arms and thighs.
  • Sessions: usually one session, with yearly maintenance often suggested.
  • Comfort: vibration and surface cooling with every pulse; topical numbing cream if you prefer it.

Mechanism

How Thermage FLX Works

Monopolar RF Energy

Deep Dermal Heating

Monopolar radiofrequency travels into the deep dermis and the subcutaneous layer. As the current passes through tissue it produces heat, and once the tissue is warm enough, collagen fibres contract and the formation of new collagen is set in motion.

Collagen Remodelling

Progressive Skin Tightening

That controlled thermal injury activates fibroblasts, which lay down new collagen over the three to six months after treatment. This slow remodelling is what tightens and lifts the skin, so the change builds over time rather than appearing all at once.

Comfort System

Vibration & Surface Cooling

To keep treatment comfortable, the FLX handpiece cools the skin surface before, during and after every pulse and adds a vibration sensation. Deep heating can then be delivered while the surface stays protected, and most people at IN Eternity Clinic manage the treatment without local anaesthesia.

Treatment Zones

Addressable Areas

01
Face & Jawline

The face is where Thermage is used most. It treats mild to moderate laxity over the cheeks, jowls and jawline, and the Face Tip covers the whole face in one session, placing hundreds of pulses evenly across the area.

02
Eyes & Periorbital Area

A separate Eye Tip, approved for use around the eyes, treats hooding of the upper lid and laxity of the lower lid. Thermage is one of a small number of radiofrequency devices cleared specifically for the eye area, which makes it a precise choice for tightening there.

03
Neck & Décolletage

On the neck, Thermage can tighten laxity over the platysma and improve skin quality across the décolletage. Where neck laxity is more marked, or the angle under the jaw needs more definition, Dr Sin Yong may suggest Time Freeze Laser LCLR® or the VF Lift – Vertical Facelift instead.

04
Body — Abdomen, Arms & Thighs

On the body, Thermage treats loose skin on the abdomen (for example after pregnancy or weight loss), the inner arms and the thighs. When the aim is contouring with fat reduction as well, the 4K Body Lift or a Time Freeze Laser LCLR® body protocol usually gives a more noticeable, measurable change.

Understanding Thermage Limitations

Because Thermage relies on one mechanism, monopolar RF heat building collagen in the dermis, it leaves fat distribution, volume loss and wider skin quality largely unchanged, along with the other shifts that come with facial ageing. For moderate to advanced laxity, or where more lift and contour are wanted, Dr Sin Yong often suggests the VF Lift or Time Freeze Laser LCLR® as the main protocol, since each works on several aspects of facial ageing within one session.

“Thermage firms the skin you already have. Whether that is enough depends on what else is changing beneath it, and that is what the assessment is for.”
— Dr Sin Yong, Medical Director, IN Eternity Clinic
Dr Sin Yong’s Recommendation

For More Significant, Longer-Lasting Results

At IN Eternity Clinic, Thermage is a well-established option for mild skin tightening. At consultation Dr Sin Yong often suggests his own protocols instead of, or alongside, Thermage, because they are designed to work on several aspects of facial ageing at the same time.

Most Often Recommended
Developed by Dr Sin Yong

Time Freeze Laser LCLR®

Thermage tightens with one RF heating mechanism. Time Freeze Laser LCLR® instead uses dual-wavelength laser energy, adjusted zone by zone in real time, to lift, lipo-model and improve skin integrity in the same session. It treats the same laxity concerns with finer targeting, wider skin-quality benefits and an LCLR lipo-modelling mechanism that Thermage does not have.

  • Full face and neck lifting in one 30-minute session
  • LCLR lipo-modelling for point-zone fat reduction
  • Skin integrity improvement across the treated zone
  • Dual-wavelength precision vs monopolar RF blanket heating
  • Used for droopy eyelids, jowls, the neck and body zones

For Structural Facial Lifting
Dr Sin Yong’s Own Protocol

VF Lift — Vertical Facelift

The VF Lift – Vertical Facelift is Dr Sin Yong’s customised non-surgical facelift protocol, using dual-energy technology set zone by zone. Instead of the even monopolar RF heating of Thermage, it works towards three aims in one session: lifting laxity and jowls, reducing excess facial puffiness, and restoring hollow cheeks through adipose stem cell and collagen stimulation, which Thermage is not designed to do.

  • Lift: loose skin, jowls and a descending midface
  • Reduce: facial fat and excess puffiness
  • Restore: natural volume to hollow cheeks and the under-eye
  • Shared by Dr Sin Yong at the CLASSYS APAC 2026 International Symposium
  • Trains practitioners internationally

Thermage is still a sound clinical choice and remains available at IN Eternity Clinic. At your consultation, Dr Sin Yong recommends the protocol, or combination, that fits your anatomy, how much laxity you have and what you want to achieve.

Frequently Asked Questions — Thermage Singapore

Most people have a single Thermage session, with change building over 3–6 months as new collagen forms. A yearly maintenance session may be suggested to hold the result, which suits people who prefer one treatment a year. The VF Lift and Time Freeze Laser LCLR® are also long-lasting options, and Dr Sin Yong will explain how they differ for your face.
Thermage FLX uses vibration and surface cooling to keep treatment comfortable. Most people feel a deep heat with each pulse; some are comfortable without anaesthesia, while others prefer a topical numbing cream first. How it feels varies with personal sensitivity and the area treated. The VF Lift and Time Freeze Laser LCLR® are generally well tolerated and do not produce the same intensity of heat.
Thermage uses monopolar radiofrequency to heat the deep dermis and drive collagen remodelling, a single-mechanism way of tightening skin. The VF Lift combines volumetric RF with focused ultrasound, set zone by zone, to lift, reduce puffiness and restore hollow cheeks at the same time, three aims Thermage alone does not cover. Time Freeze Laser LCLR® uses dual-wavelength laser energy for lifting, lipo-modelling and skin integrity together. Because the VF Lift and Time Freeze work on a wider range of facial concerns in one session, Dr Sin Yong often recommends them where more than skin tightening is needed.
A Thermage session usually holds for about 1–2 years, with the peak at around six months as the new collagen matures, and a yearly top-up is often advised. Treatment does not pause ageing: volume loss, gravitational descent and changes in skin quality carry on regardless. That is why many people at IN Eternity Clinic pair Thermage with energy-based lifting protocols for a more complete result.
Thermage FLX treats the face, the eyelids (using the Eye Tip), the neck, décolletage, abdomen, arms and thighs. The Eye Tip stands out because few RF devices hold a specific clearance for the eye area, where it is used for hooded upper lids and lower-lid laxity. When the goal is body contouring with fat reduction rather than tightening alone, the 4K Body Lift or a Time Freeze Laser LCLR® body protocol is usually more targeted.

Thermage uses radiofrequency to heat the dermis broadly, firming skin and stimulating collagen where dermal laxity is the concern. Ultherapy uses focused ultrasound delivered to deeper layers, lifting where descent of deeper tissue dominates. They address different layers, and where both are present a combined approach is often chosen.

Thermage results develop over the months following treatment as collagen renews, and are commonly maintained with periodic sessions. The interval is planned individually according to baseline laxity.

Pricing for Thermage depends on what your assessment finds, the areas treated and how the plan is staged, which differ from person to person. Because the plan is tailored, IN Eternity Clinic explains the full plan and cost at consultation rather than a fixed price.

At IN Eternity Clinic, Thermage provides radiofrequency skin tightening in Singapore for the face and body, firming and smoothing the skin. As a monopolar RF treatment, it sits alongside the clinic’s other non-surgical lifting protocols.

Thermage in Singapore — Radiofrequency Skin Tightening Explained

How Thermage FLX works

Thermage FLX uses monopolar radiofrequency to heat the deeper layers of skin while protecting the surface with cooling, stimulating collagen contraction and renewal. This is what makes Thermage skin tightening effective for smoothing crepey texture and firming the face and jawline in a single session.

Thermage vs Ultherapy

A common question is Thermage vs Ultherapy: Thermage tightens and smooths skin texture using radiofrequency, while Ultherapy lifts deeper structures using focused ultrasound. Some patients benefit from one, others from both — Dr Sin Yong advises based on your skin and goals rather than a fixed package.

Comfort, results and downtime

Thermage FLX treatment is more comfortable than earlier generations thanks to vibration and cooling, with essentially little downtime. Firming continues over the following months as collagen renews. Thermage Singapore price reflects the treatment area and is discussed transparently at consultation.
