Friends who are losing weight or have experienced the “torture” of losing weight must know that when we lose weight, not all parts of the body will lose fat at the same rate, such as arms, thighs, stomach, etc. These parts are not only prone to fat accumulation, but once accumulated, they will become the final “big boss” of weight loss that is stubborn and difficult to eliminate. Therefore, many people will choose to “defeat” this stubborn situation through medical beauty.
Introduction
In addition to general fat, human body fat also has stubborn fat, which is the most stubborn part of fat, mainly subcutaneous fat. It is easy to form and accumulate, but at the same time difficult to lose and eliminate. It has a higher density and is more sensitive to insulin. It will only start to be consumed after losing general fat. Among all the fat that can be consumed, it absorbs the least blood flow.
Compared with ordinary fat, stubborn fat contains a high density of alpha adrenaline receptors, which are different from the beta adrenaline receptors of ordinary fat. The main function of alpha adrenaline receptors is to inhibit lipase, regulate the supply of muscle energy during exercise, and inhibit fat burning; while the function of beta receptors is to activate lipase, accelerate muscle contraction, and burn fat. Therefore, stubborn fat is more sensitive to insulin, has lower peripheral blood flow, and is more difficult to burn than visceral fat and intramuscular fat, so it is also more difficult to lose.
Cause
The causes of stubborn fat can be divided into internal and external causes.
Internal factors: 1. Sensitivity to insulin Insulin promotes fat accumulation. Fat in some parts of the body (such as waist, abdomen, thighs, etc.) is particularly sensitive to insulin and can easily turn into stubborn fat over time. 2. Slow peripheral blood circulation The blood flow in different parts of the human body is different. The blood flow in the thighs or buttocks is slower than that in the arms and chest. Fat metabolism is difficult in areas with slow blood flow, and hormones such as catecholamine that can promote lipid decomposition are more difficult to enter fat cells. The blood flow around stubborn fat is low and the blood circulation is slow, so it is more difficult to release, decompose and transport fat. Over time, fat becomes more stubborn and more difficult to lose. 3. Low body temperature The body temperature in areas where stubborn fat accumulates is generally low, and low body temperature can easily hinder metabolism, so this part of fat is more difficult to consume and can gradually become stubborn fat. 4. Estrogen In addition to the effects of insulin on stubborn fat, estrogen is also a factor that increases alpha receptor activity, so women usually have more stubborn fat than men. ◎External factors: 1. Irregular lifestyle Irregular lifestyle leads to endocrine problems, which makes it difficult for fat to stimulate adrenaline. Staying up late, lack of sleep and excessive stress make it easier to produce cortisol, which will form stubborn fat over time. Therefore, you must first adjust your lifestyle during fat loss. 2. Eating habits Poor diet structure, love of high-sugar and high-calorie food snacks, excessive fat intake, and fast accumulation. Of course, if you consume a lot of carbon water all year round, especially some refined carbohydrates such as white rice, noodles, bread and other processed staple foods, it will directly lead to a surge in insulin and synthesize stubborn fat. 3. Lack of exercise If you sit for a long time or lack exercise after excessive calorie accumulation, it will naturally cause fat accumulation to be greater than consumption, and the areas prone to stubborn fat will start to store fat first. 4. Age The main source of calories consumed by the body is basal metabolism, followed by activity and exercise calories, and the thermal effect of food. As we age, lack of exercise, and lower basal metabolism, we will find it increasingly difficult to lose fat, which is related to the higher levels of testosterone and growth hormone in youth. 
Specific symptoms and affected populations
Compared with “normal fat”, stubborn fat is easier to accumulate and still burns slowly even with exercise and diet, so it is very stubborn.
①Everyone has different areas of stubborn fat. This is determined by genes and lifestyle. Some people have their belly, while others (like me) have their hips and legs. It is difficult to change it.
② Stubborn fat will be lost last. The body will only break down stubborn fat after it has broken down and utilized fat in other parts of the body.
③ Women’s stubborn fat is mainly concentrated in the buttocks, sides of thighs, inner thighs, lower abdomen, upper arms and other parts; while men’s stubborn fat is mostly concentrated in the lower abdomen around the navel, sides of the lower waist and other parts.
Treatment options
Generally speaking, we can only lose general fat as much as possible through exercise, dieting and other methods of losing weight. For stubborn fat, more precise local lipolysis methods would be more appropriate and efficient.
At Ai Beauty Clinic, for localized fat reduction, you can choose lipolysis injections or CoolSculpting to accurately locate stubborn fat areas, quickly eliminate fat cells in the body, and reduce fat fundamentally. At the same time, you can also choose BTL to achieve simultaneous fat reduction and muscle gain to tighten and sculpt your body lines.
A. CoolSculpting
Introduction:
The CoolSculpting CCCOLSCULPTIN system was developed and designed by global dermatologists DR.R.ROX ANDERSON and DR.FIETER MANSTEIN at Massachusetts General Hospital, a hospital co-founded by Harvard Medical School. It is a cryolipolysis device produced by ZELTIQ AESTHETICS, INC, a well-known American medical equipment manufacturer. It is used in more than 80 countries and regions around the world, with more than 5 million treatment cases. It has obtained the US FDA, China CFDA and EU CE certification. Its safety, effectiveness and economic benefits make it the best body sculpting project in the world.
Working principle:
CoolSculpting cryolipolysis mainly utilizes the fact that fat cannot tolerate cold. Through a low-temperature treatment device at about 4~5℃, the freezing wave is transmitted to the part with more fat. When it encounters cold, the fat will die by itself and then be excreted from the body through the natural metabolic process, achieving the purpose of slimming and shaping. Precise low temperature and professional probe can ensure that fat cells are frozen to death without harming other tissues of the body. One treatment can reduce 22.4% of fat.
process:
1. Face-to-face consultation: Through measurement and other steps, a detailed fat mass assessment will be conducted, including the range, size, angle, etc. The doctor will develop a treatment plan suitable for you according to different areas based on your situation and expected results.
2. Preoperative preparation: mark the treatment area, clean and disinfect, and install the nozzle.
3. CoolSculpting treatment: Place the treatment head close to the skin surface to freeze fat.
4. Precautions after surgery.
Duration: 1 hour
Suitable for the crowd:
- People who are not severely obese and want to reduce local fat;
- People with a lot of stubborn fat deposits;
- People who want to avoid the risks of surgery, liposuction, and general anesthesia and want non-invasive fat burning and body shaping;
- People who don’t have much time for exercise and fitness and want to dissolve fat locally and efficiently in a short time;
The first Asian medical beauty institution in the UK to introduce the latest version of CoolSculpting® ELITE cryolipolysis device, which uses the only technology that can completely “freeze” fat cells to death without any damage to the body. It is a non-invasive and perfect fat reduction treatment that is both effective and safe.

B. Lipolysis injection
Introduction:
The lipolysis injection is currently the safest and most effective method for non-surgical local weight loss. It is especially suitable for small-area local weight loss and eliminating stubborn fat, such as double chins, faces, thighs and other difficult-to-reduce areas. After the lipolysis injection, the metabolism of fat is accelerated, fat is degraded and absorbed, and at the same time, the skin can be tightened and lifted.
Working principle:
The working principle of the lipolysis injection is to inject a liquid containing slimming ingredients directly into the subcutaneous fat layer of the human body. It will destroy the cell membrane, thereby destroying the fat cells, while increasing the amount of lipase in the local fat, promoting fat activation, and breaking down the fat into small states, which are then excreted from the body through the lymphatic system as the body metabolizes.
process:
- Consultation: A plan will be developed based on your requirements and the thickness of the fat layer, and the area to be injected will be marked out.
- Preoperative preparation: Apply local anesthetic, clean and disinfect the treatment area.
- Lipolytic injection: Blunt needle flat injection, try to ensure one needle per area.
- Postoperative precautions.
Duration: 30-45 minutes
Suitable for the crowd:
- People with localized fat accumulation and stubborn fat, including arms, inner thighs, joints, stomach, etc.
- People with cellulite, improve cellulite;
- People who have side effects of bumpy and uneven skin after liposuction;
- People who want to avoid the risks of surgery, liposuction, and general anesthesia and want non-invasive lipolysis;
- People who don’t have much time for exercise and fitness;
The fat-dissolving needles used are the British Aqualyx and the Italian Desobody, both of which are lipolysis products licensed locally in the UK. They can accurately locate the fat-dissolving areas, quickly eliminate fat cells in the body, and fundamentally reduce fat without rebound after surgery. The non-invasive treatment does not cause damage to the body and is safe and reliable.

C. BTL EMSCULPT
Introduction:
BTL Maxus muscle pacemaker is a non-invasive innovative device developed by the British company BTL that can “build muscle + burn fat” at the same time. It has no radiation, does not freeze the body to harm the body, does not burn the skin with high temperature, and is efficient and safe. Seven independent studies in the United States provide strong academic support, and it has obtained triple certification from the US FDA, CE, and TGA. It can achieve 16% muscle growth and 19% fat loss at the same time. It is the same slimming and shaping black technology used by many big stars such as Kardashian.
Working principle:
BTL Maxus uses the core HIFEM technology, which is high-intensity focused electromagnetic field technology. The energy pulse of 30 minutes of treatment stimulates 20,000 strong muscle contractions. The electromagnetic waves of the treatment head penetrate as deep as 7cm into the muscle layer, inducing the muscles to perform “super-contraction movement” that the human body cannot achieve independently, stimulating the super-speed metabolism and strong decomposition of fat cells, while accompanied by muscle strengthening and growth effects, achieving the effect of fat burning + muscle gain.
process:
- Face-to-face consultation: We will develop appropriate treatment plans for different areas based on your condition and expected results.
- BTL Maxus treatment: Place the treatment head on the treatment area and gradually increase the energy.
- Postoperative precautions.
Duration: 30-45 minutes
Suitable for the crowd:
- People who are not severely obese and want to lose weight in certain areas, including arms, abdomen, and buttocks;
- People with sagging skin who want to reshape their body, optimize their lines, and tighten their skin;
