After considering, Hanh decided to test the filler for “the little girl”. After the injection, Ms. Hanh monitored for 2-3 days, without any abstinence, the private area looked different, helping her to be more confident. Not only Hanh, many women seek to inject fillers and own fat to rejuvenate the private area. According to the ad, filling the private area after the service is done, the big lips will be fuller and plumper, helping women be more confident when “close”. A cosmetic doctor in Pham Dinh Ho, Hanoi shared that he also often performs this procedure for customers. Most women come to this service because they have “little girl” atrophy, some have vaginal atrophy syndrome, so the solution of injecting fillers helps them to be more confident, especially for women over 45 years old. . However, when beautifying, doctors also recommend that women learn carefully to avoid risks. Many women go to inject fillers to rejuvenate the ‘little girl’. Obstetrician Le Thi Kim Dung – Thai Ha Occupational Health Center said that doctors often use the method of filling the private area with filler injections or autologous fat injection. With these 2 methods, large lips will be filled and become more beautiful. With autologous fat injection, fat will be taken from the person’s waist, abdomen or thighs. Then the doctor performs centrifugation to select the strongest fat cells to inject and transplant into the big lip. For the method of injection with filler, it is necessary to choose the type of filler that is suitable for each person’s condition. Dr. Dung said that the advantage of injecting fillers is that the effect is fast, but it only takes a few months to re-inject. And autologous fat injection, like the procedures of autologous fat injection in other areas of the body, must ensure very strict conditions otherwise it will cause inflammatory and necrotic complications. Dr. Dung noted that when injecting fillers for “the little girl”, it is necessary to consult the doctor very carefully. In some cases, women injecting botox to fight ‘little girl’ wrinkles can help their partners be more satisfied, but for women, it is not good at all. The private area including the vulva, vagina, and perineum can increase inflammation, damage when ‘close’ due to loss of elasticity, making women lose their feelings when in love. While the vagina contains many blood vessels, possible nerve risks include nerve paralysis, bleeding, and thrombophlebitis. The drug can also cause irritation to the body. Therefore, ‘little girl’ injections are only really effective when used with the right dose, depth and correct injection site. Compared to the surgery to reduce and beautify the girl, these filling methods are not as effective in the long run.

Mr. Nguyen Duc Hoang (Hai Ba Trung, Hanoi) said that he has lost his bald hair for about ten years. Although he is only 40 years old, his hair is already bald. Initially, Mr. Hoang also went to buy drugs to treat, stimulate hair growth … but the effect did not improve. Bald hair makes him lose confidence in communication. Many times I want to shave, but I can’t because of the specifics of the job, if I shave, I have to change the way I dress. Mr. Hoang works for a joint venture company specializing in supplying imported aluminum and plastic materials, so the reception is also a lot. Every time he goes out to meet a customer, everyone asks him “Are you a director, are you a boss”.. a lot. Many times Mr. Hoang goes with his boss to meet new customers, sometimes the partner rushes out to shake Mr. Hoang’s hand, leaving the real boss behind. Hoang only smiled wryly, sometimes his boss frowned because he was mistaken. Recently, Mr. Hoang heard about the hair transplant method, he was very interested in it, but when he consulted a few medical facilities, there were many problems that were not as simple as growing rice. Mr. Bui Phan Vinh (born 1987, Thai Binh) is also bald. Friends often joke that when he washes his face, it takes a long time to wash his hair. Vinh confided that to others, strong hair exudes masculinity, elegance and bravery, while he, on the contrary, loses confidence. Vinh went to the hospital and bought hair growth spray, but it didn’t work. Whenever there is an advertisement for a hair growth drug, Vinh buys and uses it from oral drugs to stimulate hair growth to spray and apply, but the results are not satisfactory, making him depressed. By now, at 34 years old, Vinh is still afraid to get married, because his hair is bald, he still feels guilty when taking pictures or having certain exchanges. Illustration. How is the treatment? BSCKII – Quach Thi Ha Giang – National Hospital of Dermatology said that male hormone hair loss is the most common type of hair loss in men. The forehead, top, and temples are common hair loss sites. In these areas, the hair becomes thin, reducing the diameter of the hair, and reducing the density of the hair. Many men are not too concerned about their problems, peacefully living with thinning hair that progresses naturally, but many people are very worried, guilty, low self-esteem, significantly affecting their quality of life. . Many men complain that baldness causes psychological guilt. Dr. Giang said that currently the treatment of male pattern baldness needs to determine the cause and there are many single or combination therapies that have been performed for patients with positive effects. However, dermatologists need to advise patients to understand the advantages and disadvantages of each therapy so that patients can adhere to and maintain treatment. Currently, hair transplant to treat baldness is of great interest to many people, according to Dr. Giang, this technique was first performed in 1930 in Japan for the hair loss area in the eyebrows. This is a measure that can clearly and long-term improve male pattern baldness. Hair transplant is a technique to permanently transfer hair follicles from the occipital area of ​​the scalp to the bald area at the top and forehead. With modern techniques, the survival rate of transplanted hair follicles can reach over 90%. The prerequisites for this procedure are stable hair loss and a sufficient amount of hair in the occipital region for implantation (> 40 hair follicles/cm2). According to Dr. Giang, there are two basic autologous hair transplant techniques: FUT (follicle unit transplantation) and FUE (follicle unit extraction). Each technique has different pros and cons. First, FUT hair transplant technique – take a scalp flap from 8-12mm wide, 20-30cm long in the occipital area or horizontally behind the ear, then separate each hair follicle to transplant into the bald area. The flap of skin that has just been cut will be sutured, there is a risk of scarring. Monday, FUE hair transplant technique – precisely remove individual hair follicles from the scalp, then graft to the bald area. This method has the advantage of less scarring, less pain, less swelling, but it takes a long time to perform the technique. After the hair transplant, Dr. Giang said, the hair follicles will enter a phase of cessation of growth, so it takes at least 3 months to see cosmetic improvements in those who are transplanted. Local hair follicles can still continue to progress naturally, so it is necessary to continue to maintain systemic and topical treatments such as minoxidil, finasteride for the best effect. In addition, men can be treated with other methods such as pills, low-dose laser…

Acne is a very common condition in teenagers, which occurs when too much sebum is produced and clogs the pores. The most common places where acne appears are the face, neck, back, chest, and shoulders. Although it does not affect health much, but if not taken care of well, acne can cause permanent scars. There are a number of subjective causes such as: poor skin hygiene awareness, studying and living in a humid environment, staying up late, working under prolonged stress, using a variety of foods and drinks that cause irritation. , spicy food, the habit of pressing and squeezing acne spots with your hands, causing skin damage and swelling… The treatment will be a dermatologist combining many drugs, from cleansers, antibiotics, acne cream… The treatment time is about 1-5 months, depending on the severity. To help the treatment process be highly effective, you need to note: keep the skin clean with an appropriate cleanser; do not wash your face too much and do not rub your skin vigorously when washing your face; using “oil-free” cosmetics; do not squeeze the pimples with your hands; do not use a lot of foods and drinks that cause irritation such as: seafood, foods with too much fat, alcohol, beer,… Should drink a lot of filtered water and eat a lot of vegetables.

“At first I felt my eyes were small, not deep and bright enough, then I wanted my nose to be taller, the nose to shrink, I wanted my lips to be a little thinner, and felt uncomfortable with my chin not pointed enough. I feel my skin is loose and I want to improve it with laser treatment. I can’t stop thinking I’m ugly, “Miao said. The Red News . Just entering university, her work is heavy, but every day Miao looks in the mirror, takes selfies and takes videos to see her face for hours. She even skipped class at times just to look in the mirror. Not only that, she constantly searches for images and information about “defects” and “perfect beauty” of the human body, listing unsatisfactory details on her body such as eyes, nose, chin. , the distance between the chin and the neck. Although she has no physical defects, Miao cannot help but obsess that she is not beautiful enough. Miao used a ruler to measure the facial contours of her face and found a solution to edit it online. She consulted with several famous cosmetic hospitals in China, talking to a group of strangers about plastic surgery. She found all the ways to perform surgery, but she was worried because she was still a student, unable to afford hospital fees. Finally she asked her parents for money. Initially, Miao repeatedly asked for eyelid surgery. Because it was a quick surgery, it did not take time and had little impact on school, so her parents agreed. But after having double eyelids, she still feels unwell because the ratio between her eyes and nose is not right. Miao continued to ask for money for eye and nose surgery. In response to requests for continuous surgery from her daughter, Miao’s parents told her to postpone and think carefully after the exam, but she insisted on going and did not care about school. Her parents gradually realized the instability as her daughter fell into a love of cutlery. Can’t stop thinking I’m unstable Yan Guojian, a psychotherapist at the No. 4 People’s Hospital in Chengdu, said that Miao was addicted to plastic surgery not because of her ugly appearance, but she had a mental illness called “appearance guilt. “also known as” impaired body disorder “(BDD). At present, the cause and physiological mechanism of the disease are not fully understood. Many psychologists believe that it can be caused by many factors, such as being ridiculed or overused in childhood. Yan Guojian believes that Miao suffers from a very typical form barrier. According to Yan, “physical inferiority complex” (BDD) is a form of obsessive compulsion, implying a flawless appearance or only minor defects, but patients always exaggerate those points and feel that they are someone who is extremely ugly or disgusting that attracts the attention of others. People with “defective body disorder” tend to be addicted to plastic surgery. In Miao’s case, her looks are flawless, but she always thinks she’s not pretty enough and mentally depressed. When sharing with her parents or friends, they did not understand her psychological problem, so they only commented objectively that she looked good. When she points out a point of dissatisfaction on her body and asks if they feel it, if the other party says “yes”, Miao will suffer, but if they say “no”, she thinks they are lying. She was trapped in feelings of pessimism, pain, and even suicidal thoughts. Yan Guojian said that according to available foreign epidemiological data, the incidence of BDD (Body dysmorphic disorder) in the general population is 0.7% to 2.4%. In special population groups, such as dermatology and cosmetic surgery patients, the incidence of BDD is higher, reaching from 3.2% to 53.6%. In cases of mild defect, surgery has improved them, but the healing effect is generally not good. Many patients remain dissatisfied after surgery, or undergoing symptoms of substitution, altering their focus on the body, leading to the emergence of new defects and continued modification. As a result, the patient is increasingly disgusted with his appearance. Most illnesses begin in the teenage years and persist, often becoming chronic with improper treatment. BDD is often accompanied by disorders of depression and anxiety. “It is important to note that such patients have a high risk of suicide, especially when accompanied by depressive symptoms. Patients have difficulty controlling themselves and have to look into mirrors, over-modulate, ask others many times, and ask friends or family members to evaluate their appearance to get the assurance that the points on their body are ‘normal'”.

lehai@yahoo.com Oily skin is the most common skin type, with oily layers on the skin that make the face shiny, especially when there is reflected light. To identify oily skin, you can wipe the oily face with oil blotting paper anywhere, or use your hand to rub it on your forehead to see more oil. In addition, oily skin pores are also larger than other skin types such as dry skin. Under each pore there is an sebaceous gland. It produces natural oils called sebum to help retain moisture and keep skin smooth and soft. When the sebaceous glands produce too much oil, the skin becomes lustrous. Therefore, oily skin is more prone to pimples because sebum mixes with dead skin cells and gets stuck in the pores, leading to blackheads, whiteheads, and pimples on the face, easy to catch sun causing bruises. You should wash your face every morning, evening and after exercising, gently manipulate, avoid rubbing too hard. To prevent acne, look for sunscreens that contain zinc oxide and titanium dioxide. Do not use sunscreens that contain perfumes or oils. Remove make-up before going to bed. Do not touch or stroke the face continuously, easily spread dirt, oil and bacteria from hand to face.

A new architecture called MobileStyleGAN greatly reduces the number of parameters based on style GAN and reduces computational complexity.

In recent years, in generative image modeling, there have been more and more applications of generative confrontation networks (GAN). Style-based GAN can generate different levels of detail, ranging from the shape of the head to the color of the eyes. It implements SOTA in high-fidelity image synthesis, but the computational complexity of the generation process is very high. It is difficult to apply to mobile devices such as smart phones.

Recently, a study focusing on the performance optimization of style-based generative models has attracted everyone’s attention. This research analyzes the most difficult computational part of StyleGAN2 and proposes changes to the generator network, making it possible to deploy a style-based generation network in edge devices. The research proposed a new architecture called MobileStyleGAN.Compared with StyleGAN2, the amount of parameters of this architecture is reduced by about 71%, the computational complexity is reduced by about 90%, and the quality of the generation is almost unchanged.

Comparison of the generation effect of StyleGAN2 (top) and MobileStyleGAN (bottom).

The author of the paper has put the PyTorch implementation of MobileStyleGAN on GitHub.

Paper address: https://arxiv.org/pdf/2104.04767.pdf

Project address: https://github.com/bes-dev/MobileStyleGAN.pytorch

The training code required for this implementation is very simple:

The effect of StyleGAN2 (left) and MobileStyleGAN (right) is shown.

Let’s take a look at the details of the MobileStyleGAN architecture.

MobileStyleGAN architecture

The MobileStyleGAN architecture is built on the basis of the style generation model. It includes a mapping network and a synthesis network. The former uses the mapping network in StyleGAN2. The focus of this research is to design a computationally efficient synthesis network.

The difference between MobileStyleGAN and StyleGAN2

StyleGAN2 uses pixel-based image representation and aims to directly predict the pixel value of the output image. MobileStyleGAN uses frequency-based image representation to predict the discrete wavelet transform (DWT) of the output image. When applied to 2D images, DWT converts the channels into four channels of the same size, which have lower spatial resolution and different frequency bands. Then, the inverse discrete wavelet transform (IDWT) reconstructs the pixel-based representation from the wavelet domain, as shown in the figure below.

StyleGAN2 uses a skip-generator to form an output image by explicitly summing the RGB values ​​of multiple resolutions of the same image. The study found that when the image is predicted in the wavelet domain, the prediction head based on skip connection has little effect on the quality of the generated image. Therefore, in order to reduce the computational complexity, this study replaces the long jump generator with a single prediction head of the last block in the network. But predicting the target image from the middle block is of great significance for stable image synthesis. Therefore, this research adds an auxiliary prediction head to each intermediate block and predicts it according to the spatial resolution of the target image.

The prediction head difference between StyleGAN2 and MobileStyleGAN.

As shown in the figure below, modulation convolution includes modulation, convolution and normalization (left). The depth separable modulation convolution also includes these parts (middle). StyleGAN2 describes modulation/demodulation for weights, and the study applies them to input/output activations respectively, which makes it easier to describe depth separable modulation convolution.

The StyleGAN2 building block uses ConvTranspose (left in the figure below) to upscale the input feature map. The research uses IDWT as the upscale function in the MobileStyleGAN building block (right in the figure below). Since IDWT does not contain trainable parameters, this study adds additional depth separable modulation convolution after the IDWT layer.

The complete building block structure of StyleGAN2 and MobileStyleGAN is shown in the figure below:

Distillation-based training process

Similar to some previous studies, the training framework of this study is also based on knowledge distillation technology. The research uses StyleGAN2 as a teacher network and trains MobileStyleGAN to imitate the functions of StyleGAN2. The training framework is shown in the figure below.
