Subcutaneous fat that sticks to your waist and hips and doesn't fall off. If the amount of subcutaneous fat is reduced, the overall volume will be reduced, but rather than being thin, having a moderate amount of muscle will result in a healthy, well-balanced and attractive body line.

Many medical slimming machines target only the fat layer for treatment, but EMSCULPT can increase muscle mass as well as reduce fat . It is said to be a medical slimming machine suitable for those who are not good at voluntary exercise and those who have little muscle mass.

In aesthetic medicine, medical slimming is performed using cooling, lasers, high frequencies (RF waves, radio waves), and HIFU (high-density point ultrasound). It uses energy called electromagnetic energy to deeply stimulate the muscles that account for about 35% of the body .

You can aim for more effective medical slimming by understanding in advance the principles, effects and risks of emsculpting, and precautions after treatment.

Dr. Naoki Arao of Arao Clinic, the leading emsculpter

Mechanism of increasing muscle and reducing fat with emsculpt

m sculpt Emsculpt is a medical slimming machine developed by British company BTL. By irradiating the treatment area with HIFEM®, a 30-minute treatment will cause about 20,000 powerful muscle contractions.

It is said that it is possible to increase muscle mass and reduce fat cells while sleeping because the treatment is performed while lying on your back or lying down in bed.

The effectiveness and safety of Emsculpt have been proven by research conducted in the United States, and Emsculpt and HIFEM® technology have obtained 6* patents for machine parts and structures from the USPTO (United States Patent and Trademark Office). increase.

Energy "HIFEM®" used in emsculpting

hifem Emsculpt uses HIFEM® (High-Intensity Focused ElectroMagnetic Field). Using energy that applies a strong magnetic field (up to 1.8 tesla), which is similar to MRI that takes cross-sectional images of the body , electromagnetic force stimulates motor neurons (motor neurons) , causing muscle contraction.

Unlike X-rays, it does not use radiation, so there is no need to worry about medical exposure, and there is no risk to the body due to electromagnetic fields (some people cannot receive treatment due to pacemakers, foreign bodies, etc.).

Muscle contraction induced by stimulating motor neurons with HIFEM®

Except for reflex actions, we usually move muscles by repeatedly contracting and relaxing according to commands from the brain transmitted through motor neurons. However, Emsculpt does not give instructions from the brain, but directly gives HIFEM® stimulation to the motor neurons to move the muscles regardless of intention.

When nerve cells are strongly stimulated by HIFEM®, the positive and negative electrodes are reversed (depolarized) inside and outside the nerve cells, causing nerve cell excitation and muscle contraction. When the energy of HIFEM® causes a powerful muscle contraction called hypermaximal muscle contraction, the muscle fibers become larger and thicker, which is said to increase the density and volume of the muscle and improve its shape.

About 20,000 muscle contractions in 30 minutes

Mechanism of fat cell reduction by muscle contraction

When a large amount of FFA (free fatty acid) is released by super-strong muscle contraction by HIFEM®, it accumulates in adipocytes and causes adipocyte dysfunction. As a result, fat cells undergo apoptosis (cell death) and are eventually excreted from the body over several weeks, so the thickness of the fat layer is said to decrease .

What is FFA (free fatty acid)?

Fatty acids produced by the decomposition of neutral fats need to be broken down into FFAs in order to use neutral fatty acids as energy.

Apoptosis by esculpting

In addition, neutral fat that is not used as energy is accumulated as visceral fat and subcutaneous fat and causes obesity.

Difference between HIFEM® and EMS

In addition to HIFEM®, there is a method using EMS (Electric Muscle Stimulation) to move muscles independently of commands from the brain. EMS stimulates motor neurons with electrical currents to cause muscle contraction. In addition to being used for muscle training, it is also used in the medical field as rehabilitation for people who are unable to exercise on their own due to disabilities. The difference from HIFEM® is the depth of action on the muscle.

EMS works only on the surface layer of the muscle, but HIFEM® works at a depth of about 7cm under the skin , so it can be said to be more effective because it can work on all layers of the muscle.

Areas that can be treated with emsculpt

  • abdomen
  • buttocks (hip)
  • thigh
  • upper arm
  • Calf

Emsculpt irradiated area

Msculpt is a medical slimming machine that can be expected to improve posture, etc., because it trains deep muscles.

The treatment is performed while lying in bed. After attaching the belt to the treatment site and fixing the part (applicator) of the machine that irradiates HIFEM® between the body and the belt, the irradiation starts.

Msculpt can also be used for upper arms, thighs and calves Initially, emsculpting was only applicable to the abdomen and hips, but with the development of the applicator, it has become possible to treat the upper arms, thighs, and calves .

In abdominal treatments, it is possible to train the external oblique muscles, internal oblique muscles, and transversus abdominis muscles, focusing on the rectus abdominis muscle, so it is possible to achieve a so-called "six pack" in which the contours of the muscles stand out as the subcutaneous fat is reduced. There is none.

In the treatment of the buttocks (hip), the gluteus maximus and gluteus medius muscles are targeted, and it is possible to improve the sagging (sagging) caused by muscle weakness due to lack of exercise and aging, and aim for a tight and upward hip line.

The calves act as a pump that returns blood to the heart, so if the muscles are strengthened, the function of the pump will also be strengthened, which can be expected to improve coldness and swelling.

Small muscles such as the biceps and triceps of the upper arm and the gastrocnemius of the calf are treated using a special applicator that is smaller than the abdomen and buttocks.

Those who are suitable for m sculpt

Emsculpt is a medical slimming machine that can be operated regardless of gender or weight. Just by lying in bed, you can increase muscle mass and reduce fat layer at the same time, leading to a healthy body line.

  • Those who want to tighten the waist by creating a constriction
  • Those who want to tighten and slim their upper arms and slack
  • Those who want to tighten their calves
  • Those who want to create beautiful abdominal muscles by reducing subcutaneous fat in the abdomen
  • Those who want to lift their hips but do not want to build muscle in other parts of the body through training
  • Those who want to add muscle to the trunk to improve posture
  • Athletes who want to gain more muscle while training regularly
  • Those who want to exercise but cannot voluntarily exercise
  • Those who have not been able to obtain sufficient results from conventional slimming machines that only reduce fat, injections, or dietary restrictions.
  • Those who want to improve their performance in exercise by building muscle strength
  • Those who want to tighten the abdomen after childbirth and prevent urine leakage

In addition, it is said that by increasing muscle mass, you can increase your basal metabolism and aim to create a body that is less likely to gain weight.

Sustainability of emsculpt effect and frequency of treatment

One course is recommended to repeat irradiation 4 times at a pace of once a week or once every two weeks. After the procedure, you may experience muscle soreness. Muscle pain is a sign that muscle fibers are repairing, so if there is no muscle pain, the next treatment can be performed 3 days after the treatment.

In general, it is said that the effect lasts for about 3 to 6 months after completing one course of treatment. Depending on your physical condition, such as lack of muscle, you may need to increase the number of times or take a second course.

Vibration and pain during emsculpting

Repeat 3 types of vibration patterns during treatment

When irradiation starts, the stimulation pattern of phases 1 to 3 as shown below is automatically switched. The 5-minute vibration pattern from 1 to 3 is repeated 6 times, and the treatment is completed in about 30 minutes .

  1. Spontaneous contraction (warming up)
  2. hypermaximal muscle contraction
  3. Discharge of waste products (relaxation/cooldown)

During the irradiation, along with the vibration, there is a sound of the irradiation, which may be understood by those who have experienced MRI.

3 Phases of Emsculpting Treatment

Emsculpting pain

Abdominal surgery feels like your abdominal muscles are being grabbed, and your hips feel like an electric shock. For the first 5 minutes, you will not feel any pain, but it will gradually decrease. Since it is a medical slimming machine that approaches the muscles, it is said that the more muscle mass, the stronger the pain .

Therefore, it seems that people with less muscle mass tend to feel less pain. The practitioner pays close attention and gradually increases the output level of Msculpt, but if the pain is strong or you feel something abnormal, please tell us immediately without holding back.

Postoperative pain and downtime

Due to the repair of muscle fibers, some people may feel muscle soreness for a few days from the day after the treatment . The symptoms are the same as muscle soreness from regular training or exercise. Approximately 48 to 72 hours are required for muscle fiber recovery, so the next treatment is recommended after that.

However, the time required for muscle mass and muscle fiber repair varies from person to person, so there may be no muscle soreness. It does not mean that muscle pain is more effective, and even if muscle pain does not occur, HIFEM® can be expected to increase muscle strength by performing ultra-maximal muscle contraction.

HIFEM® energy is transmitted only to motor neurons. Therefore, there is theoretically no downtime as there is no harm to internal organs or damage to other tissues such as skin burns .

Emsculpt side effects and risks

Emsculpting is a non-invasive (non-invasive) procedure, so it is said not to damage the skin, internal organs, or other tissues.

Since it is a medical slimming procedure that is said to have almost no downtime, there are no burns, internal bleeding, swelling, or sagging skin. Redness may occur at the site where the applicator is attached, but it will disappear naturally within the day .

Those who cannot receive emsculpting

Those who fall under the following may not be able to undergo treatment, so please consult a doctor.

  • unwell
  • Those who are menstruating
  • pregnant
  • Those who are less than 3 months old

  • Those who have inserted metal, silicon, etc. such as gold thread into the treatment site
  • Those with untreated infection or inflammation at the treatment site
  • Those who have a history of surgery or a medical history in the abdomen
  • Malignant tumor, pulmonary dysfunction, heart disease, muscle/nerve disease, epilepsy, autoimmune disease
  • People with Bell's palsy or other serious medical conditions
  • Those taking oral corticosteroids
  • Those with a pacemaker
  • Hypertension

M sculpt treatment fee market price

*Since it may be possible to treat parts other than the above, please check with the medical institution where you will receive the treatment for details.

What is recommended for the flow of emsculpting and effective treatment

Emsculpting can be performed while wearing clothes, but it is recommended to attach an applicator directly to the bare skin in order to check the state of muscle contraction.

Also, in the case of buttocks treatment, you may change into special shorts and perform the treatment.

(1) Examination and counseling by a doctor

There is advice on appropriate irradiation intervals, number of treatments, etc. Any concerns or questions will be addressed at this time.

(2) Filling out consent form

After confirming the contents of the treatment, you will sign the consent form.

(3) Emsculpt irradiation

Lie down on the bed and wear the applicator using the special belt. Adjust if it is tight or if the belt twists and causes pain. A switch is turned on and the treatment begins. A 5-minute stimulation pattern from phases 1 to 3 is repeated 6 times, and the treatment is completed in 30 minutes.

(4) End of m-sculpt irradiation

Remove the applicator and you're done.

It is recommended to drink only water for 2 to 3 hours after the treatment.

Immediately after the treatment, the body is in a state where it is easy to absorb nutrients, so it is recommended to take only water that does not contain fat or sugar for about 2 to 3 hours . Avoid excessive drinking and binge eating.

In addition, it is said that the recovery time for muscle fibers that have been given a strong load with emsculpt is about 48 to 72 hours. It is recommended that you be aware of the intake of amino acids and proteins that are necessary for

There are no restrictions on drinking, bathing, or exercising after emsculpting.

How to keep muscles after emsculpting

Consider eating a high-protein diet and light exercise. After emsculpting, the muscles will gradually weaken if nothing is done , so it is recommended to continue light strength training. If you are not good at exercising or find it difficult to continue on your own, please consult a medical institution about regular emsculpting treatments.

How to choose a medical institution to receive emsculpting

Knowing the principle of emsculpting and the degree of pain before and after treatment, aiming for effective muscle mass increase and fat reduction

Emsculpt is a medical slimming machine that aims to increase muscle mass and reduce fat.

Therefore, if you are concerned about skin sagging and firmness, you may want to consider using it in combination with a high-frequency medical slimming machine such as Vanquish or Thermacool . Also, if the fat layer is thick, using Vanquish together can be expected to have the effect of reducing fat cells close to the muscle with Emsculpt and fat cells close to the skin with Vanquish. In addition, there are drips that help burn fat, so if you want to increase the effect, you can choose a medical institution that has a menu that can be used in combination with emsculpt.

In addition, it is important to aim for healthy slimming by keeping in mind a high-protein, low-sugar diet and moderate exercise on a daily basis, but by ingesting protein and branched-chain amino acids before and after treatment, muscle mass can be increased. is expected to increase. Therefore, some medical institutions prepare supplements and drinks after the treatment. Please also check what kind of support the medical institution considering receiving emsculpting provides .

Mr. Naoki Arao, who supervised the article, taught me about emsculpting.

What is the pain level during and after emsculpting?
Dr. Naoki Arao
During the treatment, you may feel a tingling sensation and the feeling of your muscles being squeezed, but you will gradually get used to it, so you can rest assured. Since it is not an anesthesia procedure, the greater the muscle mass, the stronger the pain.

In addition, after the treatment, symptoms such as post-exercise muscle pain appear, but disappear in a few days.
Please tell me about precautions and aftercare.
Dr. Naoki Arao
There are no particular restrictions after the treatment, but we recommend a high-protein, low-calorie diet to maintain the body line obtained from the treatment.
What is the frequency of treatments? How long will the effect last?
