Hyphen treatment consists of three layers: the "dermis layer" that is involved in the firmness of the facial skin, the "SMAS layer (superficial fascia group)" that exists underneath, and the "subcutaneous tissue" that is mainly the fat layer. It is a beauty treatment that can be expected to improve skin firmness and elasticity, improve skin sagging, and slimming effects by irradiating ultrasonic waves on the skin.
In addition to hyphen treatment, aesthetic medicine that can be expected to be effective in improving sagging includes laser treatment, radio frequency (RF) treatment, thread lift (thread lift), and face lift surgery. Hyphen treatment is the only treatment that can approach the SMAS layer other than the facelift surgery that raises the SMAS layer.
However, while the treatment effect can be expected, there are many people who are concerned about the degree of pain, side effects and risks. Before undergoing treatment, you can receive hyphen treatment with peace of mind by knowing the effects of hyphen treatment, pain, side effects, risks, and effective treatment frequency .
HIFU is an abbreviation of English "High lntensity Focused Ultrasound", which is a method of collecting and irradiating ultrasonic waves with a high frequency that cannot be heard by the human ear. .
In the same way that black paper burns when sunlight is focused on one point with a magnifying glass, the focused irradiation of ultrasonic waves on the target area causes a high temperature and heat is generated .
The effects that can be expected from hyphen treatment include a small face effect by lifting (tightening) that lifts sagging by the action of the heat generated, improvement of skin firmness, tightening of pores, and slimming effect by destroying fat cells. over.
In aesthetic medicine, in addition to hyphens, energy sources such as lasers, light, and high frequencies are used, but there are differences in the depth to which the energy reaches and the range of influence.
In hyphen treatment, the energy of strong heat gathered at one point reaches the fascia called SMAS layer under the skin .
In laser therapy and phototherapy, the wavelengths contained in lasers and light are absorbed by melanin pigments, red hemoglobin in blood, and water, and the heat generated is used to improve spots, redness, and wrinkles. Therefore, depending on the color of the skin, it may react with the melanin pigment and cause burns, making the treatment difficult.
On the other hand, high-frequency and hyphen treatments can be performed regardless of skin color. However, it may be recommended to postpone the treatment because the skin becomes hot immediately after excessive sunburn, making it easier to feel pain and heat.
However, for neck treatments, avoid the area where the thyroid gland is located.
If the sagging is not severe to begin with, even if you receive hyphen treatment, there may be no change and you may have the impression that it is "ineffective." Depending on the degree of sagging, treatments other than hyphen treatment may be suitable, so please consult your doctor during counseling or examination before treatment.
By changing the tip part (cartridge) equipped in the machine, the hyph machine can change the "ultrasound focal depth", which is the depth that the ultrasonic waves aim at, to 1.5mm, 2.0mm, 3.0mm, and 4.5mm. I can do it. However, depending on the machine, 2.0mm cartridges may not exist, and the most common pattern is 1.5mm, 3.0mm, and 4.5mm.
By changing the cartridge, you can perform treatments according to your wishes, such as "I want to improve firmness and texture", "I want to tighten the sagging of the face", and "I want to lose some weight".
|depth of focus||layer that can be irradiated|
|1.5mm/2.0mm||Epidermal layer prone to superficial fine wrinkles|
|3.0mm||The dermis layer where collagen decreases and firmness and elasticity decrease|
|4.5mm||SMAS layer involved in aging (sagging) of facial muscles|
Some hyphen machines are equipped with 6.0mm, 9.0mm, and 13.0mm cartridges for the body other than the above.
Also, the layer that can be irradiated with the above cartridge is a guideline. In the actual treatment, the doctor selects the cartridge based on the skin thickness and skin condition of each individual.
The skin is layered from the outside into the epidermis layer and the dermis layer, but the dermis layer is the majority of the skin tissue and can be said to be the main body of the skin.
About 70% of the dermis is made up of fibrous protein "collagen". Collagen is bound by a fibrous protein called "elastin", and "hyaluronic acid" fills the gaps while holding moisture, giving the skin firmness and elasticity.
These cells that produce collagen, elastin, and hyaluronic acid are "fibroblasts," which are also called factories that make collagen.
When hyphen treatment is performed with a cartridge that reaches the dermis layer where fibroblasts are located, the wound healing power that tries to repair the heat-damaged part and its surroundings works, and the fibroblasts are activated . Therefore, collagen and hyaluronic acid, which keep the skin firm and fresh, are replaced with new ones, and you can expect skin firmness, pore reduction, and skin tightening effects .
By performing hyphen treatment with a cartridge that reaches the shallow part of the dermis layer just below the epidermis layer, it can be expected to improve fine wrinkles on the skin surface.
Ultraformer III, one of the hyf machines, is capable of continuous irradiation with weak heat called "Hyf Shower®". Because the speed of continuous irradiation is fast, even weak heat can be expected to improve skin firmness and tighten pores .
Also, Hyf Shower® is done with 1.5mm or 2.0mm cartridges. Compared to other hyphen treatments, it is said that the downtime until the skin at the treatment site returns to its original state is shorter.
(*"Hyf Shower®", "Hyf Eye Shower®", and "Hyf Deep Shower®" are registered trademarks and can only be used with the Ultraformer III machine.)
The difference between hyphen treatment and other sagging treatments such as thread lift and high frequency is that it reaches the "SMAS layer" under the skin that thinly covers facial muscles.
The SMAS layer is an abbreviation for "superficial musculo-aponeurotic system", and is a thin superficial fascia that is formed over a wide area of the face while continuing from the head to the forehead, temples, neck, etc. The SMAS layer lies under the dermis layer and subcutaneous tissue (fat) and covers the muscles of facial expression.
As the SMAS layer loosens with age, it can no longer support the skin, and signs of aging such as wrinkles and sagging begin to appear. The skin tightening effect can be expected by stimulating the dermis layer to restore the firmness of the skin. It is said to have the effect of pulling up from
In addition to hyphen, there are light (IPL), laser, and high-frequency energy for aesthetic medicine that stimulates the dermis layer, but hyphen treatment is the only treatment that can approach the SMAS layer below the dermis layer without surgery. I'm here.
When the subcutaneous tissue, which is mostly composed of fat, is irradiated with hyphen heat energy, the heat destroys or shrinks the fat cells . Destroyed fat cells can be expected to have a slimming effect by gradually being discharged out of the body by "macrophages", which are a type of white blood cell and play a role in releasing dead cells and their debris from the body.
In addition, it is said that the more hyphen irradiation, the more fat cells can be damaged.
In the sagging treatment that uses hyphen to act on the SMAS layer , the SMAS layer is tightened immediately after irradiation, so immediate effects can be expected in improving sagging .
On the other hand, in the firmness improvement treatment that acts on the dermis layer, the effect begins to appear by activating fibroblasts and increasing collagen, elastin, and hyaluronic acid. Since these wound healing actions progress gradually, the effect may be felt about a month after the treatment, but it is said that the effect often appears over 2 to 6 months.
In addition, it is said that it takes 4 to 12 weeks for the destroyed fat cells to be discharged when acting on subcutaneous fat, so it is said that the effect can be felt gradually.
It is said that the treatment effect will appear even once, but if you want a higher treatment effect or depending on the condition of the skin and fat, it is more effective to receive the treatment multiple times on a regular basis.
Hyphen treatment is, so to speak, a treatment that intentionally causes injury. Immediately after the treatment, the treatment site is in a state of being injured by heat, and immediately after the treatment, the SMAS layer and fat layer are in a scab state, or the scab is about to come off.
If you receive hyphen treatment again before the wound is completely healed, it will be an act of creating a scar on the wound, which will damage the skin cells and lead to aging of the skin.
Therefore, the next treatment is 1 to 2 months after the treatment on the dermis layer, which aims to improve the firmness and elasticity of the skin, and 3 to 6 months, if it is a treatment that aims to improve skin sagging and slimming effects. Once a day is a guideline. However, the frequency of treatment varies depending on the condition of the skin and subcutaneous fat, so please follow the doctor's instructions.
It is said that there are two types of pain in hyphen treatment. One is "pain that reverberates through the bones" and the other is "pricking, stabbing pain under the skin."
Pain that resonates in the bones is pain that occurs when the forehead or near the chin is irradiated, and is said to be caused by a thermal response due to the absorption of ultrasonic waves by the cortical bone.
There are individual differences in how pain is felt. It is said that people with thin skin or thin skin are more likely to feel pain, but the pain is considered to be tolerable without anesthesia.
(1) Examination (counseling)
Since there are individual differences in bone structure, flesh, and fat thickness, we will determine a treatment policy that suits the individual.
(2) Cleansing, washing face and changing clothes
For facial treatments, cleanse to remove makeup and wash your face to keep your skin clean. In addition, in the case of treatment on the body, change into special treatment clothes.
Gel or oil is applied to the area determined by the counseling so that the energy can be easily transmitted, and the depth of irradiation, the intensity of the energy, and the number of times of irradiation are adjusted while irradiating.
The treatment is completed by wiping off the gel and oil. The treatment time is about 30 to 45 minutes for hyphen treatment on the cheeks and face line. If the face is irradiated, makeup can be applied as usual immediately after the treatment.
Although there are individual differences, it is recommended that the skin be well moisturized for 2 to 3 days after the treatment, as the skin may be dry .
In addition, you can expect a tightening effect by causing heat contraction of the protein, but due to this action, inflammation (redness), swelling, and swelling may occur in rare cases, but even if they appear, they will subside in about a week.
Depending on the person, symptoms such as "heat sensation", "dull pain deep in the skin", and "muscle pain" may occur, but it is said to subside in 2 to 3 days.
There are no restrictions on exercise or lifestyle, so you can lead a normal life immediately after the treatment.
If you have little subcutaneous fat to begin with, the effect may not appear. Also, you may not be able to receive it depending on your chronic illness or physical condition.
For those who have undergone hyaluronic acid injection, botulinum injection, or thread lift treatment with dissolving thread in the area to be treated, the swelling caused by hyphen treatment may shorten the duration of the injection treatment or thread lift effect .
Therefore, it is recommended that those who are undergoing these treatments receive hyphen treatment after about a month.
Inflammation, swelling, and edema may occur due to the thermal effect of the irradiation site becoming hot, but it will subside in about a week. In addition, post-inflammatory pigmentation may occur due to inflammation, but it will disappear over time in about 3 to 6 months.
Burns and nerve paralysis can be avoided by an experienced doctor .
In hyphen treatment, if the energy (strength) to be irradiated is incorrect, partial burns may occur. In addition, if the nerve is irradiated, symptoms such as neuralgia such as dull pain and headache, and facial paralysis may occur. Nerves are concentrated in the center of the face, so it is not possible to irradiate anywhere.
Since there are many nerves running in the face other than the center, hyphen treatment requires knowledge and experience to avoid the nerves and irradiate.
Hyphenation can also be performed at beauty salons, but the output of the hyphenation machines at beauty salons and the hyphenation machines at medical institutions are different . Esthetic hyf machines have a limiter so that the temperature does not rise to the extent that cells are destroyed, and it is said that the output is about 1/3 compared to hyf machines at medical institutions.
Destroying cells and tissues violates the Medical Practitioners Act, so if a treatment to destroy fat cells is performed at a facility where there is no doctor, it will be "illegal", and placing a medical hyph machine outside a medical institution is illegal. Not sanctioned by the Medical Practitioners Act.
In addition, when using a hyf machine for esthetics with low output, the effect and duration often differ from the expected results, and even though the output is low, there are reports of burns during the treatment [*1] ] has also been
In order to obtain satisfactory results with hyphenation, it is necessary to undergo hyphenation treatment at a medical institution, and to receive treatment under the supervision of a doctor who is familiar with the anatomy of the face, has many treatments using hyphenation machines, and has a proven track record. is important.
Rie Yamashita, who supervised the article, taught me about hyphen treatment.

Medical institution with Dr. Rie Yamashita
Rie Yamashita taught me about HIFU treatment.
Nerve focal and burning causes paralysis. Be especially careful when using 3mm or 4.5mm cartridges (transducers). Basically, it is important to firmly attach the transducer to the skin surface so as not to damage the skin surface and leave scars. I'll be careful.
・Facial nerve (mandibular marginal branch) injury: Drooping of the corners of the mouth occurs. The mandibular ramus extends from the angle of the jaw to the outside of the lip and runs between the superficial and deep lobes of the parotid gland. On the mandible, the parotid gland is also thin, so care must be taken when performing the procedure.
・Infraorbital nerve injury: It is safer to avoid irradiating the nerve running area below the infraorbital margin with a deep transducer, and avoid irradiation at a depth of 3 mm or more around the lips.
・Supratrochlear nerve and frontal nerve damage: When irradiation is applied to the forehead, paresthesia is likely to occur, and discomfort and tingling in the scalp (from the frontal area to the middle area of the occipital area) may continue for about half a year. I don't know about others, but I experienced it myself in the past, but it was painful to comb my hair, shampoo, and even have my head touched.
Advantages: Non-surgical sagging treatment leaves no scars. Highly satisfying treatment with immediate effect, combination with other treatments possible, high repeat rate.
Disadvantages: There is pain during the treatment, it is not possible to make the face less fatty (patients may complain that it is not effective in cases where it is not indicated), most of them are effective after one treatment, but the effect lasts requires regular treatment.
