High-frequency treatment is a treatment method that warms the deep part of the face and body with a constant frequency emitted from a dedicated machine to increase metabolic power and promotes collagen production, leading to slimming and improvement of skin quality . Please understand the mechanism and type, and aim for the ideal body line and skin quality.
Table of contents
High frequency is a type of electromagnetic wave. It is classified into gamma rays, X-rays, ultraviolet rays, visible rays, infrared rays, microwaves, and high frequencies according to the difference in wavelength and frequency, and the region around the frequency of 3MHz to 300MHz is high frequency, radio frequency, RF (Radio Frequency = radio). (Abbreviation for frequency) .
"Frequency" means that vibrations of the same waveform circulate in a fixed cycle, and high-frequency waves are called "high frequencies" and low-frequency waves are called "low frequencies". The two frequencies have different roles, and the high frequency is a frequency that mainly acts on blood vessels, reaching deep into the body and expanding the blood vessels to promote blood circulation and improve stiffness . On the other hand, low frequencies act on muscles and relieve stiffness by stimulating muscle contractions .
At medical institutions, the high-frequency mechanism is also used for cosmetology. When high frequencies are applied to the skin, minute vibrations are transmitted to the body, and the molecules rub against each other to generate heat (Joule heat). Joule heat warms deep inside the body, not the surface of the skin.
By continuing the high temperature state due to Joule heat, protein contraction, metabolism and collagen production are promoted, which can be expected to have a tightening effect, slimming effect, and improvement of skin firmness.
Radiofrequency treatment can temporarily raise the body temperature by + 3 ° C to 5 ° C, and depending on the site, 7 ° C by quickly warming the deep part of the skin. It is said that this promotes blood circulation and lymphatic flow, smoothes the discharge of waste products, and regulates the turnover of the skin that is reborn as new cells .
In addition, Joule heat stimulates fibroblasts in the dermis layer (lower layer of the epidermis layer) and activates the production of skin collagen and elastin . ..
Since high-frequency treatment does not damage the epidermis layer, there is almost no downtime such as scabbing after the treatment, so you can receive the treatment without worrying about the schedule of events. Immediately after treatment, it is said that you can feel the contour improvement (small face) by tightening action , but there are individual differences in skin quality improvement such as improving firmness and tightening pores, so repeated treatment is required .
These nonsurgical systems induce tissue tightening and contour changes through dermal collagen remodeling without disruption of the overlying epidermis, obviating a significant recovery period or risk of serious adverse sequelae.

High frequency is said to have a slimming effect as well as a firmness of the skin and a tightening effect on pores because the Joule heat promotes blood flow and lymphatic flow and smoothes out waste products. Since it warms the body from the deep part, it is said to be the best treatment for the lower body where it is easy to feel cold.
In addition, since the enzymes in the body are activated by applying heat, it is considered to be a medical slimming treatment that can be expected to decompose fat cells. It is said that continuous slimming treatment at high frequency improves basal metabolic rate and improves the constitution to make it easier to lose weight.
It is said that the unevenness that appears on the surface of the skin due to the enlargement of subcutaneous fat, so-called cellulite, can be improved by the metabolic action of fat cells by high frequency . In addition, by activating skin elastic components such as skin collagen and elastin, it improves the unevenness peculiar to cellulite and leads to smooth skin.
In addition, liposuction, which directly sucks subcutaneous fat with a thin tube, may cause pain and internal bleeding, but it is said that high-frequency treatment after liposuction accelerates the recovery of liposuction and has a higher slimming effect. It is said that.
Immediately after treatment with high frequency, waste products and fat cells flow into the lymphatic vessels and promote metabolism, but it is said that it takes several months before you can feel the slimming effect. There are individual differences in slimming action, and repeated treatment is required.
RF thermal stimulation is believed to result in a microinflammatory process that promotes new collagen. By manipulating skin cooling, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.

High-frequency treatment machines can be broadly divided into three types, monopolar, bipolar, and multipolar (tripola), depending on the frequency and the position and number of electrodes.
The monopolar method is a method in which Joule heat is generated by sandwiching the site where high frequency treatment is performed between two electrodes and passing high frequency energy between the electrodes. It is said that Joule heat can be generated in a relatively wide range, and it is said that it has the effect of promoting the flow of blood and lymph and promoting the discharge of waste products .
Promotes blood circulation, improves metabolism, discharges waste products, slimming, etc.
A high frequency machine with two (buy) electrodes is called a bipolar type. The tip is divided into two, and it is said that it does not leave high frequency in the body because it is an electrode that sends high frequency and an electrode that collects it (counter electrode).
It is said that frictional heat promotes the production of skin collagen and elastin by passing high-frequency energy between the two poles and stimulating the upper dermis (the shallow layer of the skin) .
Increased firmness, tightened pores, improved slack, etc.
A high-frequency machine that can stimulate both the shallow and deep layers of the skin by passing high-frequency energy between three or more electrodes is called the multipolar (tripola) type. Multipolar (Tripolar), which can be said to have both monopolar and bipolar effects, is expected to have a higher skin-beautifying and slimming effect with a single treatment .
Wrinkles, firmness, sagging, slimming improvement, etc. due to skin collagen and elastin production
In recent years, it is said that machines with the features of high frequency + α are the mainstream, and it has become possible to expect improvement of symptoms that could not be treated with a machine with high frequency alone.
In the process of repairing dermis cells by Joule heat generated at high frequency, a large amount of collagen is produced, leading to lift-up action and firm skin.
It is the world's first medical slimming machine that introduces a pulsed magnetic field. It is said that the pulsed magnetic field and multipolar heat the treatment site in a relatively short time of 1 to 2 minutes to promote the formation of skin collagen and capillaries. It is a high frequency machine that is said to have a particularly strong lift-up effect.
It is a high frequency machine that combines IPL (light) treatment that can be expected to improve multiple skin problems. It is said that the light energy that reacts with IPL melanin promotes collagen production by stimulating deeply with the heat energy of high frequency, and is a machine that improves spots and freckles.
It is said that by irradiating high frequency and ultrasonic waves at the same time, it works to tighten the skin and partially thin the skin. Ultrasound loosens fat cells and promotes fat metabolism with high-frequency energy, so you can aim for size reduction by reducing fat cells.
In addition to the slimming effect of high frequency, it is said to improve internal organ functions and metabolic power, and it is a high frequency machine that can be expected to have slimming effect while improving the constitution. In addition, it is said to be a machine that is often used together as aftercare for other slimming treatments.
Truth Scalp, which means "sculpture", is a slimming machine with the concept of achieving an ideal body shape like sculpture. It is said to work on improving unevenness (cellulite) on the skin caused by fat and on partial thinning.
It is said that the pulsed magnetic field and multipolar heat the treatment site in a relatively short time of 1 to 2 minutes to promote the production of skin collagen and capillaries. It is a slimming machine that is said to lead to the ideal body line with less pain and firmness.
It is a fat dissolving machine that the device does not touch the body. You don't have to put the handpiece directly on your skin, so you can choose any body shape. It is said that there is almost no swelling or swelling after the treatment.
It is a treatment method that combines "diode laser" and "vacuum massage" in addition to high-frequency energy irradiation. It is said to be a machine that decomposes fat cells, promotes metabolism efficiently, and excretes fat cells, and has a high slimming effect.
There are similar skin improvement and slimming treatments using high frequency, such as ultrasound, IPL (light treatment), and laser. The features of each and the differences from high-frequency machines are explained below.
Ultrasound treatment can pinpoint the SMAS layer (the part that covers the facial muscles) under the skin without affecting the surface of the skin, so it works to raise serious sagging. It is a so-called treatment.
The difference is that ultrasonic therapy aims at slimming by directly destroying fat cells, whereas high-frequency therapy is said to promote the discharge of fat and waste products by warming the deep part of the body.
Ursera Dubro, etc.
IPL treatment is a treatment method that aims to improve multiple skin problems such as age spots, freckles, reddish faces, and fine wrinkles by irradiating light energy with mild damage to the skin.
IPL treatment is said to have the main effect of improving color such as melanin and redness, and the light energy emitted improves the firmness of the skin. On the other hand, high-frequency treatment is said to have a weak effect on colors such as stains and freckles, but it has a longer wavelength than IPL and stimulates deep into the skin, so skin collagen and elastin, which are important for improving firmness and fine wrinkles, It is said to greatly accelerate the generation.
It is recommended to select a machine for treatment such as IPL treatment if the skin problem is due to "color" and high frequency if it is due to "insufficient firmness" .
Photo Facial, Photo Silk Plus, etc.
Lasers treat various problems by changing the type of wavelength depending on the target of the dye to be destroyed, such as melanin and hemoglobin. It can be said that each wavelength (laser machine) can be applied to a wide range of symptoms such as hair loss, age spots, wrinkles, and pore improvement.
Unlike high frequencies that act on a wide range of problems, laser treatment focuses on the symptoms, so laser treatment is said to be suitable for those who want to improve specific symptoms .
Q-switch YAG laser, CO2 laser, etc.
(1) Face washing / counseling
After washing your face, you will be examined by a doctor. Please confirm in advance any concerns such as the advantages and disadvantages of high-frequency treatment and self-care after treatment.
(2) Surface anesthesia
High frequency is a minimally invasive treatment that does not hurt the body and causes almost no pain, but it may be painful depending on the type and site of the machine. In that case, surface anesthesia is performed, so there is less concern about pain. Machines with high frequency + α (laser, etc.) characteristics may feel pain.
(3) High frequency treatment
Lubricating gel is applied to the treated area to perform high frequency treatment. The treatment time is about 20 to 30 minutes, depending on the machine and treatment site.
(4) Cool and finish
Immediately afterwards, I feel hot because of the treatment that warms the deep part. The affected area is cooled by cooling and the treatment is completed. In addition, it is possible to make up immediately after irradiating the face. If an anti-inflammatory ointment is prescribed, follow the doctor's instructions.
Immediately after treatment, the skin may become hot or red, but it usually subsides within a few hours. It is said that you can feel the firmness of the skin immediately after treatment with high frequency, but it is said that it takes several months to realize the action of slimming, and during that time, it is important to avoid overdrinking and eating and self-care with moderate exercise.
Also, since the treatment area is sensitive, moisturize it well and protect it from UV rays with sunscreen.
Depending on the treatment content and the machine used, pain, redness, burns, and laterality of contour improvement may occur during the procedure.
Some beauty machines that use high frequencies can be used for beauty treatments and home use, and they can be used without national qualifications, but since the machines used in medical institutions are "medical equipment", they are national. Only qualified healthcare professionals can handle it.
Depending on the medical institution, the fee for high-frequency treatment at a medical institution may be set according to the size of the irradiation range, such as "15,000 yen for a 10 cm x 10 cm area", but the entire face is 50,000 to 100,000 yen. It's about a yen . It costs more than the cost of beauty treatment salons and home beauty equipment, but you can expect a greater effect.
When choosing high-frequency treatment, by choosing a medical institution that carefully explains the price, treatment period, expected effects, etc., you can receive a convincing treatment that can be expected to improve your own problems.
