What is Thermage and how does it work?
Thermage heats tissue volumetrically with radiofrequency energy delivered from a single electrode, while cooling the skin surface during treatment.
In monopolar radiofrequency, energy travels from the treatment tip towards a grounding pad placed on the body. Along this path, the resistance of the tissue converts the energy into heat. Thermage tips are designed to cool the skin surface before and after each pulse, so that the surface is protected while the deep dermis and the fibrous bands beneath the skin are heated. The tip delivers a short pulse at each point it touches.
Heating is associated with an immediate tightening of collagen fibres, followed by the start of the tissue's repair process, during which new collagen production is expected to be stimulated. As a result, change usually develops gradually over weeks and months. Unlike focused ultrasound, energy is spread through a broader volume rather than concentrated at points, which means a more diffuse effect on the skin and its texture is intended.
When is Thermage considered, and what does it not do?
It may be considered for mild to moderate laxity and skin quality on the face, around the eyes, on the neck and on some body areas; it does not restore volume or achieve surgical change.
Thermage is usually discussed when the skin has thinned, begun to lose elasticity and facial contours have softened slightly. Laxity of the cheeks and jawline, skin quality on the neck and the appearance of fine crêpey lines around the eyelids are among the concerns assessed. Tips designed for the eye area are known to exist, and treatment there requires additional precautions such as eye protection. The treatment area is agreed at consultation.
The device does not replace fat and bone support lost with age; in such cases fillers or biostimulators may be discussed. Deeper expression lines are generally addressed with botulinum toxin. For people with significant excess skin, the achievable change may be limited. Understanding that the effect is not a tightening facelift, but a gradual process supporting tissue quality, helps to keep expectations balanced.
Who may not be suitable for Thermage?
It may not be suitable for people with pacemakers or implanted defibrillators, during pregnancy, or with active skin disease or infection in the treatment area.
Because radiofrequency energy may interfere with electronic implants, pacemakers and implanted defibrillators are regarded as an important contraindication to monopolar radiofrequency. Metal implants in the treatment area, certain dental or jaw prostheses and gold threads are also assessed individually. Treatment is usually postponed during pregnancy and breastfeeding. If there is active infection, a cold sore or eczema in the area, treatment is usually delayed until this has healed.
Areas with reduced sensation to heat, poorly controlled chronic illness and a tendency to scar may also affect the plan. If you have had fillers or threads recently, timing is agreed with the physician. Sharing your full medical history and current medication is essential for an accurate assessment of suitability. The final decision is made by the physician in light of this information and the examination findings.
What happens during treatment and afterwards?
The skin is cleansed, a temporary guide grid is marked, a grounding pad is placed and the tip is applied systematically across the planned area; most people return to daily activities the same day.
Before treatment, make-up and creams are removed and a temporary grid is marked on the skin to help distribute energy evenly. With each pulse you may feel a brief intense warmth followed by cooling. Energy levels can be adjusted during treatment according to your feedback. The length of the appointment depends on the size of the area treated, and comfort measures are discussed in advance so that you know what to expect.
Afterwards, mild redness and swelling may occur and usually settle within a few hours to a few days. Make-up and skincare can generally be resumed soon. Sun protection and keeping the skin moisturised are advisable. Because change is gradual, a review a few months later is commonly planned. Following the physician's after-care instructions helps recovery proceed smoothly, and international patients can agree in advance how that review will take place.
What are the possible side effects and risks?
Temporary redness, swelling and tenderness are common; small blisters, burns, surface irregularity and temporary numbness are reported rarely.
Common effects are short-lived. Some people notice faint marks following the grid lines or tenderness lasting a few days. Rarely, blistering, burns, crusting and subsequent pigment change have been reported. Very rarely, surface irregularity related to changes in the fat beneath the skin, or temporary changes in sensation, may occur. Tailoring energy settings to the individual and careful technique are key to reducing these risks.
It is therefore important that the device is used with genuine tips, in a licensed healthcare facility and under a physician's responsibility. If you notice unexpected pain, blistering or colour change after treatment, contact your physician. At a face-to-face consultation, your medical history, tissue structure and expectations are considered together to decide whether Thermage is a sensible option for you, and your questions are answered before any decision.
Frequently asked questions
What is the difference between Thermage and Ultherapy?
Thermage uses monopolar radiofrequency to heat a broader volume of tissue, whereas Ultherapy uses focused ultrasound to create points of heat at set depths. Which is considered depends on your tissue and the concern, and is decided by the physician.
How many Thermage sessions are needed?
It is often planned as a single session. Whether and when it is repeated depends on age, tissue structure and the response to previous treatment.
When can I return to normal activities after Thermage?
Most people return to daily activities the same day. Mild redness and swelling usually settle quickly, although this varies between individuals.
Can I have Thermage if I have a pacemaker?
Pacemakers and implanted defibrillators are regarded as an important contraindication to monopolar radiofrequency. In that situation treatment is generally not advised and other options are discussed.
Can Thermage be used around the eyes?
Tips designed for the eye area are known to exist. Treatment there requires additional precautions, such as eye protection, and suitability is assessed at consultation.
What is the difference between Thermage FLX and earlier Thermage systems?
Thermage FLX is the newer generation of Thermage and works on the same monopolar radiofrequency principle as earlier systems. According to the manufacturer, it has a larger tip and feedback features that adjust energy to the tissue with each pulse, aiming to shorten treatment time and even out energy delivery. The mechanism of action and main indications of Thermage FLX remain similar.
Is the tightness I feel right after Thermage the actual result?
No; the tightness felt immediately after Thermage mostly reflects heat-induced contraction of collagen fibres and mild swelling, and it may fade quickly. The real change after Thermage comes from new collagen production: it usually appears gradually over a few months and in some people keeps developing for up to six months. The result is therefore assessed at a review a few months later.
Can Thermage fix droopy eyelids?
Thermage may be considered for mild laxity and fine crêpey lines of the eyelid skin, but it is not expected to correct significantly drooping eyelids. Where excess skin has built up on the eyelid, or there is true drooping (ptosis) from weakness of the muscle that lifts the lid, Thermage does not change these structures, and an opinion on eyelid surgery may be needed.
Which body areas can Thermage be used on?
Beyond the face and eye area, Thermage may be considered for skin laxity and tissue quality on some body areas, such as the abdomen, upper arms and thighs, using larger tips. Where there is excess skin after pregnancy or significant weight loss, the effect of Thermage may be limited. Suitable areas are decided according to skin thickness and the degree of laxity.
