We all know that the maximum temperature that the human epidermis can withstand is 42-43℃. To stimulate the collagen regeneration in the dermis, the deep temperature needs to reach 55-65℃.
Under this condition, our skin can start the regeneration mechanism. Under the action of continuous collagen, the originally sagging wrinkles are tightened and the aged skin is regenerated. This is the process of anti-aging and wrinkle removal.
In today’s medical beauty market, there are many types of anti-aging projects, among which RF radio frequency is very prominent. It is safe and effective and recognized by many beauty industry people. Among them, monopolar RF beauty machines have been widely promoted. 6.78MHz monopolar RF anti-aging and wrinkle removal beauty equipment occupies half of the anti-aging projects!
1. What is Thermage?
Thermage, also known as Thermage, was invented by Dr. Edward W. Knowlton of the United States in 1995 and has now developed to the fifth generation. The treatment equipment, which has obtained three certifications from the US FDA, the EU CE and the China CFDA, ensures safety for the human body. It is also a globally recognized medical beauty device that can achieve significant lifting, firming and wrinkle removal effects through one treatment.
Thermage is a radio frequency device. The heat energy of 45-75° is generated by the resonance of water molecules, just like a microwave oven.
Although the energy is sufficient, the penetration depth is not strong, and it can only reach the dermis at most.
Thermage focuses on firming and is suitable for people whose face is sagging and their skin is beginning to sag. It is also effective for tear grooves, nasolabial folds, and large pores.
2. Principle of monopolar RF anti-aging treatment.
Thermage is a monopolar radio frequency. Radio frequency is an electromagnetic wave that can be emitted into the air. Electromagnetic waves have energy. When acting on the skin or body tissues, there will be an equivalent current, which will produce an ohmic heat effect, thereby generating heat, which can raise the temperature in the dermis of the skin to 60-70 degrees, stimulate the regeneration of collagen and elastic fibers, and rearrange the collagen scaffold to make the skin firm and elastic.
The penetration depth of monopolar radio frequency is deeper than that of bipolar radio frequency, and the range of skin tissue heating is deeper and wider, which can reach the deep dermis of the skin. It is volume heating, with obvious immediate contraction effect and long-term regeneration effect. Moreover, 6.78Mhz penetrates deeper than 3-4Mhz, has more concentrated energy than 40.68Mhz, and can generate heat better in the deep dermis.
Thermage belongs to radio frequency technology, which is a 6.78Mhz (megahertz) monopolar high-frequency electromagnetic wave that can be transmitted to the deep dermis of the skin. The target tissue of radio frequency is the water in the dermis-subcutaneous fat. It heats the water and collagen, which has an immediate contraction reaction, causing an immediate skin firming effect, and achieving the purpose of lifting and anti-wrinkle.
Although Thermage has no direct effect on melanin, the thermal effect of Thermage can accelerate the division of dermal cells, promote cell activity, increase cell membrane permeability, promote blood and lymphatic circulation, accelerate metabolism, anti-inflammatory, and assist in repairing the skin barrier; therefore, Thermage has an auxiliary therapeutic effect on chloasma, and patients with chloasma can do Thermage.
However, during the operation, the energy should be appropriately reduced for the chloasma area to avoid blisters caused by burns and irritation of chloasma. In addition, for vascular and vascular dominant chloasma, it is best not to apply anesthetics if the capillaries are significantly dilated and the barrier is significantly damaged. At this stage, people with chloasma are prone to adverse reactions such as anesthetic allergies and anesthetic burns, which cause inflammatory reactions in the skin and easily lead to the darkening of chloasma.

5. Precautions after treatment with a monopolar RF machine.
- It is normal to have temporary redness and swelling after treatment. Be careful not to go to a high temperature environment within one week after surgery, and it is best not to be exposed to the sun.
- Keep the skin and hair clean and hygienic before surgery. Do not wear makeup on the day of surgery, and try to remove any traces of previous makeup.
- Do not wash your face with hot water within three days (water that does not exceed body temperature is fine); pay attention to hydration. It is recommended to apply a medical mask at least 3 times a week.
- Avoid washing your face with hot water within one week after treatment, avoid hot springs, saunas, etc., and strengthen moisturizing and sun protection when going out.
- Do not drink alcohol or eat spicy food.
6. Other types of anti-aging machines.
6.1 Ultrasonic anti-aging equipment.
Ultrasonic knife (HIFU), 7D polylift, and ultrasonic gun are all ultrasonic anti-aging devices. Their working principle is to use ultrasonic transducers to focus ultrasonic waves within a specific frequency range to a focal point at a specific distance. The energy density of the focused ultrasonic waves is increased, and the focal point acts on the dermis of the facial skin. Ultrasound vibrates and heats the skin moisture, making the collagen in the deep dermis reach a focal point temperature of 60-70℃, and the protein coagulates and denatures. Then the skin self-repair mechanism is activated to stimulate the regeneration of collagen fibers, achieving the effect of lifting, firming, and facial fat reduction. Among them, the gun head of the ultrasonic gun adopts a unique ultrasonic large focal area focusing technology, which can effectively reduce the ultrasonic energy density in the treatment area, and the energy acting on the skin tissue is more uniform and gentle.
In addition to the anti-aging effect, ultrasound has a “heat-vibration” effect, which can promote blood circulation, accelerate the growth of fibroblasts and promote the production of collagen. Therefore, ultrasound has anti-inflammatory and repair effects, and also has a certain whitening effect. Therefore, patients with chloasma can also do ultrasonic anti-aging projects. However, when using the ultrasonic knife, 7D polylift, and ultrasonic gun heads for patients with chloasma, try not to use the zygomatic bone, or reduce the energy, reduce the number of repeated superpositions, and reduce heat accumulation to avoid irritation. For vascular and vascular dominant chloasma, when the capillaries are obviously dilated and the inflammatory reaction is severe, it is recommended to first repair the barrier and fight inflammation, and then use ultrasonic anti-aging after the skin barrier is stable. If the customer insists on doing it, you can use a 1.5mm or 2.0mm deep treatment head with low energy. If it is an ultrasonic gun, it is recommended to use the gun head, which is safer.
6.2 Fractional beauty machines.
The wavelength of CO2 fractional laser is 10600nm, with a high water absorption coefficient of about 780, and has a strong epidermal exfoliation and superficial dermal destruction effect. After CO2 fractional laser treatment, tiny holes will appear in the epidermis, and a “coin-shaped” skin reaction will appear. The central tissue of the laser irradiation point will be completely vaporized and exfoliated, and the surrounding tissue will have a white frost reaction due to water vaporization. The outermost tissue will have protein denaturation. The penetration and destruction depth of a single treatment is usually 80-150μm, causing columnar thermal damage/coagulation in the superficial dermis.
CO2 fractional laser is suitable for micro-exfoliation-exfoliation treatment, which can treat hyperplastic or depressed scars, laser skin resurfacing, and strong anti-aging and treatment of true wrinkles.
1927nm thulium laser is a long-pulse infrared laser. The main target tissue absorbed by the skin is water, with an absorption rate of 130. Since the moisture content of the dermis is higher than that of the epidermis, most of the energy of the thulium laser passes through the epidermis during skin treatment. The energy is mainly absorbed by the dermis and heated up. The epidermis forms an almost “translucent window” during the thulium laser transmission. Its penetration depth is about 200-400μm. If the energy is high, the epidermis will also produce slight thermal damage vaporization and slight scabs.
Thulium laser treatment belongs to the category of non-ablative-micro-ablative. Due to the deep penetration depth and obvious thermal diffusion effect of the skin, thulium laser is very safe and not easy to burn the skin. In normal treatment, there is no downtime and obvious skin damage. Therefore, it can safely heat the deep dermis to stimulate collagen regeneration and achieve anti-aging and wrinkle removal functions.
7. How to choose a reliable monopolar RF machine?
As the safest photoelectric beauty machine series in the anti-aging project, the monopolar RF beauty machine is the first choice of many people, not only because of the good anti-aging effect, but also because of its high safety. There is no need to worry about accidental damage to the facial nerves during the facial anti-aging process (such as HIFU).
For monopolar RF machines, we also need to consider two basic aspects.
7.1 Selection of RF frequency.
Compared with other frequencies, the 6.78MHz monopolar radio frequency is recognized as the best anti-aging frequency! The original American Thermage uses this frequency. Litonlaser’s Beauty Technology Training Center also analyzed and experimented on this band to prove its correctness.
7.2 Monopolar RF or bipolar RF?
Thermage uses monopolar RF, including many excellent manufacturers, such as LITONLASER’s RF machine, which is also monopolar-based.
Why choose monopolar RF? This is because when a monopolar RF machine is used for treatment, the client is usually asked to attach a negative plate on the back, so that the current of the monopolar machine will spread from the client’s face to the negative plate on the back, forming a closed circuit, which allows the microcurrent to spread throughout the body and reach the deeper skin, thus achieving the best anti-aging effect.
Bipolar RF beauty machines are usually installed on portable or home RF machines, and this effect will be greatly reduced because it will directly pass through the surface layer and leave, lacking the stimulation and regeneration of collagen in the dermis.
