In-depth Analysis of Thermage: Series 1 of 100 Questions
Thermage, as a widely praised non-invasive anti-aging therapy, holds an important position in the field of beauty. It has won high recognition from the industry and wide favor from consumers with its remarkable therapeutic effect and simple operation process. However, to fully tap into the anti-aging potential of Thermage and effectively avoid adverse reactions, it is particularly crucial to have a thorough and comprehensive understanding of its technical principles, operation norms and other professional knowledge. Starting from this issue, we will introduce the professional knowledge of Thermage in a systematic and detailed manner in the form of questions and answers. We strive to explain the complex technical concepts in a concise and clear language, making them easy to understand and helping beauty doctors master this cutting-edge technology more deeply.
What is Thermage?
Thermage is a non-invasive skin tightening therapy based on monopolar radiofrequency (RF) technology. The core principle lies in precisely acting on the skin tissue with unipolar radiofrequency energy to stimulate the remodeling and regeneration of collagen. Collagen, as an important supporting structure of the skin, changes in its quantity and quality will directly affect the firmness, elasticity and appearance of the skin. Through Thermage treatment, multiple anti-aging effects such as firming the skin, reducing wrinkles and enhancing facial contours can be achieved. It is precisely because of such outstanding therapeutic effects that Thermage has become a highly sought-after popular treatment method in the beauty industry and is widely used in various anti-aging beauty projects.
2. How does Thermage work?
Thermage precisely generates heat deep in the skin with the help of 6.78 MHz monopolar radiofrequency technology. This heat generation process has a dual effect: on the one hand, the heat causes the collagen to contract immediately, thereby generating a significant firming effect right after the treatment, allowing patients to directly feel the improvement of their skin. On the other hand, heat can also stimulate the skin tissue to initiate a new collagen production mechanism. The newly generated collagen will gradually improve the structure and texture of the skin, making it tighter and smoother. This continuous improvement effect usually lasts for 1-2 years, bringing long-term beauty benefits to patients.
3. What type of beauty device is Thermage?
In the field of beauty equipment, based on their different working principles, they can mainly be classified into three categories:
Optical devices: such as lasers, IPL photorejuvenation, etc. These devices use light of specific wavelengths to treat the skin and are often used to improve problems such as pigmentation and red blood vessels.
Sound-based devices, such as ultrasound therapy and Hydrafacial, act on the skin through the mechanical vibration or cavitation effect of sound waves to achieve effects like cleansing and lifting.
Electrical equipment: such as radio frequency, microcurrent, etc., utilize the thermal effect or bioelectric effect generated by electrical energy to improve skin condition.
The Thermage radio frequency compactor falls within the category of electrical energy equipment and employs a unique unipole radio frequency technology. Compared with bipolar and multipolar radiofrequency, its penetration depth can reach 4.3 millimeters, and it can directly reach the dermis and SMAS (superficial muscular aponeuromembrane system) layer. This deep penetration ability enables Thermage to offer more significant anti-aging effects, improving issues such as sagging and wrinkles at a deep level of the skin, and providing strong support for facial rejuvenation.
4. Unipolar radio frequency with a return electrode vs. Unipolar radio frequency without a return electrode
There are various types of radio frequency devices in design and application, among which unipolar radio frequency, bipolar radio frequency and multipolar radio frequency are relatively common classifications. Unipolar radio frequency is the most widely used in the field of beauty and can be further classified into unipolar radio frequency with a return path and unipolar radio frequency without a return path.
Thermage is a unipolar radiofrequency device with a return path. It is recognized as the world's first radiofrequency device for medical aesthetics and is a pioneer in the application of radiofrequency technology in aesthetic treatment. Unipolar radiofrequency is fundamentally different from bipolar and multipolar radiofrequency. Unipolar radiofrequency transmits energy from the treatment head to the skin and returns it through a grounding pad. This unique energy transmission method enables its energy to penetrate more deeply into the skin tissue, making it highly suitable for beauty treatment programs such as skin firming, anti-aging, and fat reduction.
In monopolar radiofrequency devices with a return path, such as Thermage, energy is transmitted in the form of current between the skin-contact electrode and the grounding pad electrode. This transmission method enables more concentrated energy and deeper penetration, and can exert significant therapeutic effects on more serious skin problems such as skin laxity and advanced aging. In contrast, in bipolar radio frequency devices, energy is distributed between two electrode points on the same handle, and its energy distribution and mechanism of action are different from those in unipolar radio frequency. When the unipolar radio frequency has no return path, there is only one electrode and no current transmission occurs. Its operating frequency is usually 40.68 MHz. At higher frequencies, electromagnetic oscillations can cause rapid rotational movement of water molecules, thereby leading to dielectric heating of skin tissue. The energy of the monopolar radiofrequency device without a return electrode is more dispersed, mainly affecting the epidermis, but the therapeutic effect is relatively less intense.
5. What are the frequency and advantages of Thermage?
The operating frequency of Thermage is 6.78 MHz, and this frequency has multiple advantages:
Heating mechanism: At lower frequencies (<10 MHz), the main heating mechanism is ionic current conduction. 6.78 MHz is lower than 10 MHz. Therefore, Thermage generates heat by passing current through the tissue resistance, ensuring a deep and effective thermal effect that can penetrate deep into the skin tissue and stimulate the contraction and regeneration of collagen.
Penetration depth: The frequency is inversely proportional to the penetration depth, that is, the higher the frequency, the shallower the penetration. The lower the frequency, the deeper the penetration. The frequency of 6.78 MHz can penetrate 6 millimeters into the skin, thereby effectively treating all related tissue layers such as the dermis and SMAS layer, meeting the needs of deep anti-aging.
Optimizing energy efficiency: At a frequency of 6.78 MHz, radio frequency ions oscillate approximately 6.78 million times per second. The more oscillations there are, the more energy is generated, which can achieve efficient and controllable heating. This frequency is regarded as the best one to balance heat generation and penetration depth, making it an ideal choice for cosmetic treatments. Due to these advantages, both monopolar radio frequency devices produced in South Korea and China adopt 6.78MHz as the standard frequency. The latest water-cooled thermage (such as Volnewmer) also adopts 6.78MHz, further verifying the wide application and effectiveness of this frequency in the field of beauty radiofrequency.
6. Power: 400W
Thermage employs 400W high-energy radiofrequency. This high-energy output can rapidly and effectively promote the contraction and regeneration of collagen. Provide sufficient energy in a short period of time to ensure the efficiency and significance of the treatment and bring more obvious anti-aging effects to patients.
7. The pulse width of Thermage
Although Thermage is a radio frequency (RF) device, it operates in a "pulse" emission mode and is released using a technology similar to a seal. This means that, like laser and intense pulsed light (IPL) devices, Thermage also has the important parameter of pulse width.
Pulse width and energy distribution: Thermage generates high energy, which increases the risk of pain and burns caused by temperature rise. To effectively control this risk, the total pulse width of the Thermage facial treatment tip is 1 second, divided into 5 sub-pulses, each with a pulse width of 200 milliseconds. During the pulse intervals, coolant is released to cool the skin, protect the epidermis and enhance the patient's comfort.
Cooling and pulse intervals: Due to the existence of sub-pulses, there are also pulse intervals for applied cooling. For the fourth-generation Thermage CPT, the existing data show that the pre-cooling time is 0.01s and the post-cooling time is 0.8s. This precise cooling design ensures the safety and comfort of the treatment.
Pulse width for eye treatment: Due to the thinner skin around the eyes, the total pulse width of the eye treatment head is shorter, at 0.7 seconds instead of 1 second. This distinction reflects the scientificity and rigor of Thermage in setting personalized parameters for different treatment areas.
8. Comparison of the fourth and fifth generation Thermage with Volnewmer
The fourth and fifth generations of Thermage maintain the same pulse width, but the cooling processes before, during and after the pulses are slightly different between the two generations. These minor improvements further optimize the comfort and safety of patients.
As a new generation of water-cooled RF equipment, Volnewmer has significant advantages:
Water-cooling system X RF Thermal: Continuously output comfort and performance improvement. The water cooling system can more effectively control the temperature during the treatment process and reduce the risk of thermal damage.
Continuous 1000ms radiofrequency pulse: Unlike other radiofrequency technologies that transmit energy in a non-continuous or intermittent manner, Volnewmer continuously outputs radiofrequency heat to ensure that the deep skin is continuously and effectively heated. This combination of low stimulation and high energy minimizes discomfort to the greatest extent while maximizing the therapeutic effect. Therefore, Thermage not only brings immediate firming effects to the skin, but also stimulates the long-term production of collagen, thereby achieving a lasting skin rejuvenation effect.
9. "Capacitive Coupling" and "Volume 3D Heating" in Thermage
Capacitive coupling technology
Thermage uses radiofrequency (RF) energy (a type of electric current) to treat the skin. There are mainly two methods for coupling radio frequency energy into tissues:
Conductive coupling (traditional radio frequency) : Energy is concentrated at the tip of the electrode, resulting in uneven heating of the tissue and increasing the risk of burns or electric shock.
Capacitive coupling (used by Thermage) : Thermage employs capacitive coupling technology, in which radiofrequency energy is evenly distributed over the surface of the treatment head, thereby generating volumetric heating within the tissue. This coupling is achieved through the conductive film on the treatment head. Radio frequency energy passes through the conductive film, ensuring uniform energy distribution and thus achieving safe and continuous heating.
Important note: Before starting the treatment, the clinician must check whether there is any damage to the membrane of the treatment head. If the membrane is damaged, it should be replaced, as a damaged membrane will be unable to perform capacitive coupling and may cause unsafe pointed discharge, affecting the treatment effect and safety.
Volume 3D heating
Thermage utilizes pulsed radiofrequency energy and capacitive coupling technology to generate cylindrical, 3D heating effects within the skin. Its working principle is as follows:
Each radiofrequency pulse penetrates the skin uniformly from the epidermis to the fascia layer, heating all layers of the tissue.
This process stimulates the regeneration of collagen in all target layers, thereby making the skin smoother and firmer.
Comparison with other treatment methods:
Ultherapy: Provides point-based heating, which may have treatment blind spots.
Thermage: It uses volume and 3D heating to fully cover the skin, ensuring no area is missed during the treatment. Thermage also has no forbidden zones, which means it is safe and effective for the entire skin. This unique heating method makes Thermage a comprehensive treatment option for skin rejuvenation.
