Monopolar radiofrequency skin tightening — Thermage FLX® delivers bulk heating to the dermis, directed at collagen remodelling. Non-invasive. No surgery. Supported by two decades of published clinical literature.
Thermage FLX is a non-invasive monopolar radiofrequency device that delivers controlled thermal energy deep into the dermis and subdermal layers. The heat is directed at collagen contraction and stimulates new collagen production over the following months, acting on skin tightness and texture.
Thermage treats the skin with a single device tip, covering large areas. The FLX (Flex) generation introduced vibration and cooling for comfort, along with a treatment accelerator and AccuREP energy tuning. It is FDA-cleared for non-invasive treatment of the face, eyes and body.
Thermage works through a single thermal mechanism — deep dermal heating. While effective for mild to moderate skin laxity, it does not address facial volume loss, excess fat distribution, or the other dimensions of facial ageing that other protocols are directed at.
Thermage delivers monopolar radiofrequency energy that penetrates into the deep dermis and subcutaneous layer. The electrical current generates heat as it passes through tissue, reaching temperatures that cause collagen fibres to contract and new collagen formation to be triggered.
The thermal injury stimulates fibroblast activity and new collagen synthesis over the months following treatment. This gradual remodelling process is what the skin tightening and lifting action depends on — the response builds progressively after treatment rather than appearing at once.
The Thermage FLX handpiece incorporates vibration sensation and surface cooling delivered before, during and after each pulse. This minimises discomfort while allowing effective deep heating. Most patients tolerate treatment well without the need for local anaesthesia.
The most commonly treated area. Thermage addresses mild to moderate skin laxity across the cheeks, jowls and jawline. The Face Tip covers the full face, delivering hundreds of pulses across the treatment zone for uniform coverage.
The dedicated Eye Tip (approved for use around the eyes) addresses hooded upper lids and lower eyelid laxity. The Eye Tip carries a specific ophthalmic clearance, making it an option for periorbital tightening.
Thermage can treat platysmal laxity in the neck and skin quality in the décolletage. Where neck laxity involves the deeper planes or the cervicomental angle, Time Freeze LCLR® or VF Lift work through different mechanisms directed at those planes.
Thermage Body is used for loose skin on the abdomen (post-pregnancy or post-weight loss), inner arms and thighs. Where fat rather than skin laxity is the concern, 4K Body Lift or Time Freeze LCLR® body protocols work through different mechanisms directed at fat.
Thermage works via a single mechanism — monopolar RF heat — to stimulate collagen in the dermis. It does not address fat distribution, volume loss, skin quality beyond tightening, or the multi-dimensional facial changes that occur with ageing. Where the assessment finds change in the deeper planes, fat distribution or volume, Dr Sin Yong may recommend VF Lift or Time Freeze LCLR® — protocols that work through different mechanisms, on different tissue targets and timelines, within one plan.
Thermage is a well-established treatment directed at the skin envelope. Where the assessment finds change in other tissue layers, Dr Sin Yong may plan one of his protocols alongside — or in place of — Thermage, because they work through different mechanisms on different dimensions of facial ageing.
Where Thermage uses a single RF heat mechanism for skin tightening, Time Freeze LCLR® combines dual-wavelength laser energy — calibrated zone-by-zone in real time — to address lifting, lipo-modelling and skin integrity improvement simultaneously. It is directed at the same laxity concerns through a different mechanism — laser rather than radiofrequency — and adds an LCLR lipo-modelling action, which is a separate mechanism from dermal heating.
The VF Lift is Dr Sin Yong’s customised non-surgical facelift protocol using dual-energy technology calibrated per zone. Where Thermage delivers uniform monopolar RF heating, the VF Lift is directed at three distinct targets: laxity and jowling, excess facial puffiness, and hollow cheeks through adipose stem cell and collagen stimulation — a different set of mechanisms from dermal heating alone.
Thermage remains a strong clinical option and is offered at the clinic. Dr Sin Yong will recommend the most appropriate protocol — or combination — at your consultation based on your specific anatomy, degree of laxity and goals.
Thermage delivers radiofrequency skin tightening in Singapore, smoothing and firming skin across the face and body. As a monopolar radiofrequency skin tightening treatment, it complements other non-surgical lifting protocols.

Dr Sin YongOn mechanism
A focused zone and a full-face plan are different undertakings, and the fee reflects the extent of what is actually treated.
The plan follows the examination — what is loose, what has descended, and what the skin itself needs determine the approach.
Some plans use one technology; others combine modalities at different depths, staged over time.
Under Singapore's healthcare advertising regulations, fees for licensable healthcare services are not published. Your fee is set out clearly at consultation, after Dr Sin Yong has assessed you — before anything is decided.
Thermage, VF Lift, Time Freeze LCLR® — the plan comes from matching the mechanism to your specific anatomy, degree of laxity and goals, which is assessed at consultation.
