Effective muscle gain and fat loss aimed at knowing the principle of M sculpt and the degree of pain before and after the procedure

Subcutaneous fat that does not fall off on the waist and hips. When the amount of subcutaneous fat is reduced, the overall volume is reduced, but a moderately muscular body is more healthy, sharp and attractive than just being thin.

Many medical slimming machines target only the fat layer, but it is EMS CULPT that can increase muscle mass as fat decreases . It is said to be a medical slimming machine suitable for those who are not good at spontaneous exercise and those who have little muscle mass.

In aesthetic medicine, medical slimming is performed by cooling, laser, high frequency (RF wave, radio wave), HIFU (hyphen, high density point ultrasound), but in M Sculpt, HIFEM® (high femme, high density focus). It uses energy called (type electromagnetic) to stimulate the muscles that occupy about 35% of the body deeply .

By understanding the principle, action and risk of M sculpt, and precautions after treatment in advance, you can aim for more effective medical slimming.

Mechanism of muscle gain and fat loss with emsculpting

M sculpt M Sculpt is a medical slimming machine developed by BTL in the United Kingdom. By irradiating the treatment site with HIFEM®, each treatment for 30 minutes causes about 20,000 strong muscle contractions.

It is said that you can increase muscle mass and reduce fat cells while sleeping because you are treated while lying on your back or lying down in bed.

The efficacy and safety of M-Sculpt have been proven by research conducted in the United States, and M-Sculpt and HIFEM® technology have been patented by the USPTO (US Patent and Trademark Office) for six * in machine parts and structures. I will.

Energy used in M Sculpt "HIFEM®"

hifem HIFEM® (High-Intensity Focused ElectroMagnetic Field) is used in M Sculpt. With energy that applies a strong magnetic field (up to 1.8 tesla) similar to MRI that captures a cross section of the body, it stimulates motor neurons (motor neurons) with electromagnetic force and causes muscle contraction.

Since it does not use radiation like roentgen, there is no concern about medical exposure and there is no risk to the body due to electromagnetic fields (some people cannot receive treatment due to pacemakers or foreign substances in the body).

Muscle contraction caused by stimulating motor neurons with HIFEM®

Except for reflexive behavior, we usually move muscles by repeatedly contracting and relaxing according to commands from the brain transmitted through motor neurons. However, M-Sculpt moves muscles independently of intention by directly stimulating motor neurons with HIFEM® rather than commands from the brain .

When a large HIFEM® stimulus is applied to a nerve cell, the positive and negative electrodes are reversed (depolarized) inside and outside the nerve cell, causing the nerve cell to excite and cause muscle contraction. It is said that when the energy of HIFEM® causes a strong muscle contraction called hypermaximum muscle contraction, the muscle fibers become large and thick, which increases the density and volume of the muscle and improves the shape.

Approximately 20,000 muscle contractions in 30 minutes

Mechanism of reduction of fat cells by muscle contraction

When a large amount of FFA (free fatty acid) is released by the 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, which is said to reduce the thickness of the fat layer .

What is FFA (free fatty acid)?

It is a fatty acid produced by the decomposition of triglycerides and must be decomposed into FFA in order to use the neutral fatty acids as energy.

Apoptosis due to escalpt

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) as a method of moving muscles regardless of commands from the brain. EMS stimulates motor neurons with electric current to cause muscle contraction. In addition to being used for muscle training, it is also used in the medical field as a rehabilitation for those who are unable to exercise on their own due to disabilities. The difference from HIFEM® is the depth that acts on the muscles.

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

Areas that can be treated with M sculpt

  • abdomen
  • Buttocks (hips)
  • Thighs
  • Upper arm
  • Calf

Irradiation site of M sculpt

M Sculpt is a medical slimming machine that can be expected to improve posture because it trains deep muscles.

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

M sculpt can also be applied to the upper arm, thighs and calves Initially, only the abdomen and hips were indicated for M-Sculpt, but the development of an applicator has made it possible to perform treatments on the upper arms, thighs, and calves .

In the abdominal treatment, the external oblique muscle, internal oblique muscle, and transverse abdominal muscle can be trained centering on the rectus abdominis muscle, so it is impossible to make a so-called "six pack" in which the outline of the muscle emerges as the subcutaneous fat decreases. There is none.

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

The calf works as a pump that returns blood to the heart, so when the muscles are strengthened, the pump also works, which can be expected to improve coldness and swelling.

For small muscles such as the biceps and triceps of the upper arm and the gastrocnemius of the calf, a special applicator that is smaller than the abdomen and buttocks is used for treatment.

Those who are suitable for M Sculpt

M Sculpt is a medical slimming machine that can be used regardless of gender or weight. Just sleeping in bed will increase muscle mass and reduce fat layer at the same time, leading to a healthy body line.

  • Those who want to make a waist and tighten it
  • Those who want to tighten and thin the upper arm and slack
  • Those who want to tighten the calf
  • Those who want to reduce subcutaneous fat in the abdomen and create beautiful abdominal muscles
  • Those who want to raise their hips but do not want to build muscle in other areas during training
  • Those who want to build muscle in the trunk to improve their posture
  • Athletes who want to gain more muscle while training with regular training
  • Those who want to exercise but cannot exercise voluntarily
  • Those who have not been able to obtain sufficient effects with conventional slimming machines that reduce only fat, injections, dietary restrictions, etc.
  • Those who want to improve their performance during exercise by strengthening their muscles
  • 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 basal metabolism and aim to build a body that is hard to gain weight.

Duration of effect of M sculpt and frequency of treatment

It is recommended as one course to repeat the irradiation four times at a pace of once a week or once every two weeks. After the procedure, muscle soreness may occur. Muscle soreness is a sign that muscle fibers are being repaired, so if you do not have muscle soreness, you can perform the next procedure 3 days after the procedure.

Generally, it is said that the effect lasts for about 3 to 6 months after the end of 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 M sculpt procedure

Repeat 3 types of vibration patterns during the procedure

When the irradiation starts, the following stimulation patterns from Phase 1 to Phase 3 are automatically switched. The vibration pattern of 1 to 3 for 5 minutes is repeated 6 times, and the treatment is completed in about 30 minutes .

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

During irradiation, along with vibration, there is an irradiation sound, as you may know if you have experienced MRI.

Three phases of M sculpt treatment

Pain of M sculpting procedure

The abdominal treatment has a pain like abdominal muscles, and the hips have a pain like running electricity. The pain is not felt strongly for the first 5 minutes, but it gradually decreases. Since it is a medical slimming machine that approaches muscles, it is said that the more muscle mass there is, the stronger the pain .

Therefore, it seems that people with less muscle mass tend to feel less pain. The practitioner should take great care to gradually increase the output level of M Sculpt, but if you feel any pain or abnormality, do not put up with it and tell it immediately.

Post-treatment pain and downtime

Some people may experience muscle soreness between the day after the procedure and a few days after the procedure to repair the muscle fibers. It is the same symptom as muscle pain caused by normal training and exercise. It takes approximately 48 to 72 hours for muscle fiber recovery, so the next procedure is recommended after that.

However, the time required to repair muscle mass and fibers varies from person to person, so you may not have muscle soreness. It does not mean that muscle pain is more effective, and even if you do not have muscle pain, you can expect the effect of muscle gain by performing super-maximum muscle contraction with HIFEM®.

HIFEM® energy is transmitted only to motor neurons. As a result, there is theoretically no downtime, as there is no adverse effect on internal organs or damage to other tissues such as skin burns .

Side effects and risks of emsculpting

M-Sculpt is a non-invasive (non-injurious) procedure that does not impose any strain on the skin, internal organs or other tissues.

Since it is a medical slimming procedure with almost no downtime, there are no burns, internal bleeding, swelling, or sagging skin. Redness may occur in the area where the applicator is attached, but it will disappear spontaneously during the day .

Those who cannot receive M sculpt

If you fall under any of the following, please consult your doctor as you may not be able to receive the treatment.

  • Those who are ill
  • Those who are menstruating
  • Pregnant
  • Those who have given birth less than 3 months
  • Those who have tattoos on the treatment area
  • Those who have metal such as gold thread, silicon, etc. inserted in the treatment site
  • Those who have untreated infection or inflammation at the treatment site
  • Those who have a history of surgery or a history of surgery in the abdomen
  • Malignant tumor, lung dysfunction, heart disease, muscle / neurological disease, epilepsy, autoimmune disease
  • Those with Bell's palsy and others with serious illness
  • Those who are taking oral corticosteroids
  • Those with a pacemaker
  • People with hypertension

Market price of M sculpt treatment fee

Since it is a free medical treatment (out-of-insurance medical treatment), the charge varies depending on the medical institution, but the price is roughly as follows.

Part Reference fee (1 time) Reference fee (4 times one cool)
abdomen Approximately 100,000 yen to 220,000 yen Approximately 480,000 yen to 770,000 yen
Hip Approximately 100,000 yen to 180,000 yen Approximately 480,000 yen to 630,000 yen

* There may be cases where treatment is possible for parts other than the above, so please check with the medical institution receiving the treatment for details.

The flow of M sculpt treatment and what is recommended for effective treatment

M-Sculpt can be performed while wearing clothes, but it is recommended to attach a precursor directly to the bare skin to check the contraction of the muscles.

In addition, in the case of buttock treatment, the treatment may be performed by changing into special shorts.

(1) Doctor's examination and counseling

There is advice such as appropriate irradiation interval and number of treatments. If you have any concerns or doubts, ask at this time.

(2) Filling out the consent form

After confirming the details of the procedure, sign the consent form.

(3) M sculpt irradiation

Lying on the bed, attach the applicator using a special belt. Adjust if it is tight or if the belt is twisted and painful. The switch will turn on and the procedure will begin. The 5-minute stimulation pattern from Phases 1 to 3 occurs repeatedly 6 times, and the procedure 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 procedure, the body easily absorbs nutrients, so it is recommended to consume only water that does not contain lipids or sugars for about 2 to 3 hours . Avoid excessive drinking and binge eating.

In addition, it is said that the recovery time of muscle fibers that have been heavily loaded with M-Sculpt is about 48 to 72 hours, and in order to accelerate recovery, sugar and stimulants are avoided, and muscle gain is gained within 1 hour immediately after the procedure. We recommend that you be aware of the intake of amino acids and proteins required for this.

There are no restrictions on drinking, bathing, exercising, etc. after M sculpting.

How to keep muscles after M sculpting

Be aware of light exercise in a high-protein diet. If you do nothing after M-Sculpt, your muscles will gradually weaken, so it is recommended that you continue light strength training. If you are not good at exercising or it is difficult for you to continue, please consult your medical institution about regular M sculpting.

How to choose a medical institution to receive M sculpt

M Sculpt is a medical slimming machine that aims to gain muscle and lose fat.

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

In addition, it is important to aim for healthy slimming by keeping in mind a high-protein / low-carbohydrate diet and moderate exercise on a daily basis, but by ingesting protein and branched-chain amino acids before and after the treatment, it has the effect of increasing muscle mass. Is said to increase. Therefore, some medical institutions provide supplements and drinks after the procedure. Please also check what kind of support medical institutions that are considering receiving M sculpt provide .

Arao Clinic's M Sculpt

Professor Naoki Arao, who supervised the article, taught me about M-Sculpt.

How much pain do you have during and after Msculpting?
Dr. Naoki Arao
During the procedure, you may feel a tingling sensation and a squeezing muscle, but you will gradually get used to it, so you can take it with confidence. The more muscle mass you have, the stronger the pain tends to be, as it is not an anesthesia procedure, but if you feel pain, the output level will be adjusted, so please do not hesitate to tell us.

In addition, after the treatment, symptoms such as muscle pain after exercise appear, but they disappear within a few days.
Please tell me about precautions and aftercare.
Dr. Naoki Arao
There are no particular restrictions after the procedure, but we recommend a high-protein, low-calorie diet to maintain the body line obtained during the procedure.
How often are you treated? How long will the effect last?
Dr. Naoki Arao
We recommend treatment every 3 days to 1 week to eliminate muscle pain after treatment, and the effect lasts for about half a year after 4 treatments per course.
