Hair on the face is the same as eyebrows, so you can't just take it off. If the delay is not good, some places may be more fierce. Especially Mao Mao in the upper lip, if bacteria invade or infect, it will affect the whole body's blood health. There have been cases of blood diseases caused by triangular injuries before.
Too long and thick body hair will affect the appearance. In order to realize the beautiful dream of smooth and delicate skin, modern women have tried various hair removal methods, and even more and more men who are troubled by their thick facial hair have begun to pay attention to the effects of various hair removal methods. From the traditional plucking hair removal method to the advanced and ideal laser hair removal method at present, each has its own characteristics, and the relevant contents are summarized as follows.
Historical review of 1
It is human nature to love beauty. In ancient times, people painted sugar on their faces to remove excess hair, so as to smooth their faces. This is the earliest depilation method recorded so far [1]. China has a long history, and women's aesthetic consciousness about eyebrows appeared very early. People began to trim their eyebrows in the pre-Qin period. In The Book of Songs Feng Wei Shuo Ren, there is a poem that "moths throw themselves into the fire and bow their heads", and Li Sao also says that "many women envy their eyebrows". At that time, the State of Chu had the tradition of thrush after thrush. Because thrush was black, it was called "black eyebrow", and "Interpretation of Names" said "black, generation also. Destroy the eyebrows and replace them with this painting. " Dating back to the Wei, Jin, Southern and Northern Dynasties, when a girl gets married, there will be an adult ceremony of "opening her face" (commonly known as "twisting her face"), that is, pulling up a filament with both hands, biting the middle with her teeth, and the whole face will roll down and back, twisting off her hair and making her face beautiful. With the changes of the times and the continuous improvement of living standards, people's pursuit of beauty is more extensive. Women who love beauty realize that thick hair on their lips affects the beauty of their faces. Excessive armpit hair and leg hair also bring a lot of inconvenience to wearing sleeveless clothes or short skirts. So various hair removal methods are applied, such as mechanical hair removal, chemical hair removal, physical hair removal, laser hair removal and so on.
2 Evaluation of various depilation methods
2. 1 mechanical hair removal method
2. 1. 1 extraction method: some ladies use tweezers to remove excess eyebrows and facial hair. This hair removal method is simple and cost-free, but the local pain is obvious during hair removal. According to the structure of hair, the part outside the skin is called hair shaft, the part inside the skin is called hair root, and the swollen part at the end of hair root is called hair ball [2]. Pulling out can't fundamentally destroy the hairball part. After 2-8 weeks, hair will grow again [3]. Although this method is the simplest method of hair removal, it is generally not used for large-scale hair removal. In addition, repeated plucking will not only lead to hair follicle allergic reaction, but also leave scars for people with scar constitution.
2. 1.2 shaving method: shave the body hair with a male razor or a special razor. This method is simple and quick, but it can only remove the hair shaft. After 1-3 days, the hair will regenerate, and it is often "deteriorated" and "out of control". It is also one of its disadvantages that the skin is easily injured and infected when scraping. Therefore, although scraping has always been a safe and effective facial hair removal method for men, it is rarely favored by women [4].
2.2 Chemical hair removal method: At present, chemical hair removal agents used for hair removal include depilatory cream, depilatory cream and depilatory liquid. There are nearly a hundred kinds of chemical reagents in the synthesis, among which the main components are thioglycolate, the combination of mercaptan and alkali, calcium hydroxide and sodium hydroxide. In this method, chemical agents are applied to local skin, and their chemical components can immediately corrode and dissolve hair shafts, thus achieving the effect of hair removal quickly. Because the hair roots under the epidermis can also be dissolved by chemical depilatory, compared with shaving, the hair growth rate is slow and the effect can last for more than 2 weeks. In addition, this method is also a more affordable choice in terms of cost. However, this method is not suitable for eye area and mucosal tissue, and depilatory cream, depilatory cream and depilatory liquid contain corrosive components. Repeated long-term use may cause damage to the skin and cause chemical and allergic dermatitis. Therefore, chemical hair removal is not an ideal hair removal method.
2.3 Physical hair removal method
2.3. 1 hair removal method: hair removal method is one of the commonly used methods for large-area temporary hair removal in beauty salons. Although the operation is troublesome, hair removal is fast and economical. Hair removal wax is divided into frozen wax and hot wax. The cost of frozen wax is higher than that of hot wax. The main components of frozen wax are various resins, which have strong adhesion and are mostly suitable for skin depilation in sensitive parts. Hot wax is mostly a mixture of beeswax and resin. It needs to be heated and melted before use. First, leave the hair to be treated with a long hair shaft of about 3mm, apply wax to the skin along the hair growth direction, then lay a layer of cloth flat, and then remove the cloth against the hair growth direction to achieve the purpose of hair removal. This method can be regarded as an improvement of plucking, so the hair grows back after 2-6 weeks. However, in the course of treatment, this method will cause the hair roots and hair follicles in the skin to be distorted, resulting in endogenous hair, which is easy to aggravate and secondary folliculitis (using hot wax) or other types of skin infections [6]. This method is not suitable for patients with diabetes, varicose veins, skin ulceration and inflammation.
2.3.2 Electric hair removal method: Insert tiny metal needles around each hair follicle, apply current, cause electrolytic reaction of tissues, destroy hair follicles and hair balls, and achieve the purpose of hair removal. This method belongs to permanent hair removal. After many electrolytic treatments, the hair follicles and hair balls in the "growth center" of hair can be destroyed, and the effect of hair removal can be achieved. This method is suitable for coarse and hard hair, but it requires higher operators. Only when the fine needle just pierces the hair follicle, especially around the hair bulb, can it have better curative effect. Its biggest shortcomings are time-consuming, obvious pain and high cost. Sometimes skin erythema, edema and scar constitution may appear, and patients may form keloids locally after receiving treatment. In addition, this method is not suitable for patients with cardiac pacemakers [7]. Therefore, only a few patients choose electrolytic hair removal.
2.4 Laser hair removal method: The international beauty community believes that laser hair removal is a revolutionary high-tech beauty medical technology. It is the most advanced permanent hair removal method at present [7]. 1963, goldman first proposed the method of destroying colored hair follicles with ruby laser. Ohshiro and maruyama also found that the treatment of giant nevus with ruby laser can lead to depilation, but at the same time it is accompanied by serious epidermal damage. Through further research, they put forward the theory of "selective photolysis" as the theoretical basis of laser hair removal [8]. According to this theory, under appropriate wavelength, pulse duration and light energy density, laser and heat can penetrate the dermal layer of skin, and hair follicles containing melanin can absorb light with a specific wavelength to generate heat, which instantly generates high temperature from the hair shaft to the deep part of hair follicles, making hair follicles degenerate, shrink and destroy, achieving permanent hair removal without damaging surrounding skin tissues, with safety, few complications and lasting curative effect. The different wavelength lasers used for hair removal are: Nd:YAG； with the wavelength of 1 064nm; Ruby laser with wavelength of 694 nm; Emerald laser, etc. , each has its advantages and disadvantages [8]. Liu Chunli et al. [9] applied the solid-state process semiconductor laser (wavelength 800nm, spot diameter 9 mm×9mm, pulse width 5-30ms, energy density value 10-40j/cm2) produced by coherent Company of the United States as 134 patients, and drew the following conclusions: the laser hair removal effect is reliable, the operation is simple and the speed is fast.
Modern laser technology has developed by leaps and bounds. At present, the most respected method is "photon hair removal". The principle of hair removal is the same as other lasers. It uses high-energy photon output to selectively destroy hair follicle tissue without damaging skin and sweat glands, and can effectively remove hair of various colors and textures in various parts of the body. At the same time, the large-area spot (spot area is 22 mm×55mm) does not need continuous cooling operation, which also shortens the treatment time. The growth cycle of hair is generally divided into growth period, rest period and regression period. Under normal circumstances, about 80% of hair is in the growing period. Melanin is the most in the growing hair follicle, and it absorbs the light emitted by laser most strongly, making it the best target for laser hair removal. The hair of each part is scattered and regenerated at different times [2]. Therefore, each part needs to be treated 3-5 times, but the interval is different. For example: face every 3 weeks 1 time, lower limbs every 2-3 months 1 time, underarm 1 time, etc. At any time, some hair follicles are in resting stage and retrogression stage, so they are not sensitive to laser treatment. About 10% hair may regenerate after depilation, but the new hair will become sparse, pale, soft and inconspicuous. According to the light and heat absorbed by melanin, the color of patients' skin is closely related to the curative effect [10]. Too much light absorbed by the skin will affect the strength of destroying hair follicles [1 1]. Therefore, people with dark skin are more vulnerable than people with white skin [1]. The treatment of laser hair removal has higher requirements for operators. Adjusting energy density and pulse width according to different parts, skin color and hair thickness can avoid local swelling, erythema and even inflammation caused by improper operation. Contraindications of laser hair removal treatment are: ① pregnant women; (2) recent sun exposure (1-3 months); ③ Open wound; ④ Wound infected person; (5) patients with skin diseases; ⑥ Epilepsy patients; ⑦ No upper eyelid. Laser hair removal is indeed superior to other hair removal methods, but whether it is the best treatment for hair removal needs long-term observation and research [12]. In addition, the high cost of treatment is the biggest disadvantage of this method.
3 outlook
Although the methods and means of hair removal emerge one after another, each has its optional advantages and some unsatisfactory places. So far, there is not an economical, simple, painless and lasting ideal hair removal method. It is gratifying that beauty experts at home and abroad are constantly trying to develop new hair removal methods. Not long ago, the oil depilatory produced by Bristol company, which specializes in cosmetics in the United States, passed the clinical experiment and will be put on the market soon after being approved by fda. The action principle of this product is the key enzyme needed to chemically stop facial hair growth, which is non-irritating, convenient, rapid and efficient. With the progress of society and the development of the times, we look forward to the emergence of more efficient and perfect depilation methods and make them serve the society.
According to the older generation, older girls and kannika nimtragol used to "wipe their faces" before the Spring Festival. Is to pull up a thin thread with both hands, bite the middle with your teeth and roll on your face. It is said that this will unscrew the hair from your face and make your face exceptionally clean. I haven't tried this old cleaning method, no matter how effective it is, but modern technology does provide us with many "brightening methods". You might as well try.
Excess facial hair generally appears on the upper lip, chin and both sides of the face. Before choosing a hair removal method, it is best to ensure that these sweating inducing factors are not abnormal secretion of hormones. If you think your hair is growing abnormally or your face is thick, then I suggest you see a doctor first and ask him/her to help you analyze the reasons.
If the growth of hair is not caused by abnormal hormone secretion, there are many ways to help you get rid of these extra hairs.
Many women use pliers to remove facial hair, but this method is not the best choice, because repeated removal may lead to allergic reactions of hair follicles, and for some people, this method will leave scars. Unless you only need to remove a few hairs that grow occasionally, then it is best not to take this approach.
The depilatory cream can penetrate deep into hair follicles and dissolve hair roots. This method is ideal and effective for removing large areas of hair (such as legs), but it may be problematic when used on the face, because it will bring allergic reactions and cannot remove all hair at the same time. On the other hand, depilatory cream is a relatively affordable choice. Generally speaking, the effect can last for one to two weeks.
Wax removal is a common method. Generally speaking, it is effective to remove the hair on the upper lip and sides of the face, but it is not recommended for you to use it on the chin, because using wax there will make the newly grown hair thicker. Depending on the type of hair, the effect of hair removal is between two and six weeks.
Electrolysis uses low-voltage current to destroy hair follicles. Its advantage is that the effect is more lasting than depilatory wax and depilatory cream. The disadvantage is that it takes time and money. When using this method, finding a good beautician is the key, because if there is something wrong with the operation, it may leave scars. Ask the customer in front before hair removal to make sure to use a new electroacupuncture every time. It is recommended that those women with more local facial hair choose this method.
The secret of hair removal
Many methods have been used, and finally it is found that the most effective method is scraper, and the most useful tool is not beautiful color.
Women use scrapers, men don't! Find one with lubrication function and multi-layer structure (with several blades).
Closing the handle not only has high hair removal efficiency, but also is said to have the effect of peeling dead skin (why are men not better than women?
Show old? It is related to shaving every day, which is more useful than skin care. ) The whole face is smooth after hair removal.
Make-up is also very pleasing. I think it makes sense. In ancient times, women had to "wipe their faces" before getting married, but at that time they used boiled eggs and cotton thread, which definitely hurt. Now our tools are easier to use. Only when they do it.
Close the bathroom door tightly so as not to be embarrassed by others. Ha ha. Because of the delicate face and fine hair,
The action should be gentle, just use water as lubricant, and the scraper gently touches the face, so don't press it hard. The direction of force is against the direction of hair growth. Try it a few times and you will be proficient.
