That's for sure. The reasons for the above-mentioned "fatal" danger are as follows: 1 A set of equipment The sanitary problem of repeated use of nail appliances by many people is a major health hazard. In some places where nail shops are concentrated, such as shopping malls, there are often more than a dozen small shops sitting in rows on the aisle of 100 meters. The nail tools provided by the store to customers are not clean; Towels, tweezers, scissors and other appliances used can not be "disinfected by one guest" at all; The operating place and nail tools are not disinfected and the hygiene is not up to standard. However, if nail tools are not disinfected as required, it is easy to be infected with diseases such as tinea manus, onychomycosis, paronychia and hepatitis. (self-examination: what will happen to the body with hepatitis) health tips: pay attention to the health warnings issued by nails. 2 frequently change nail polish and stick artificial nails. Some small shops will disinfect their nails with alcohol, but this can't effectively prevent the spread of diseases. Because nail tools are made of plastic, metal, foam, towels and other different materials, it is necessary to adopt a variety of disinfection methods, such as flame disinfection, boiling, soaking in disinfectant or high-pressure steam sterilization. Sterilization with hot water or alcohol alone is not enough to kill fungi. The safest way is to bring your own nail tools. 3. There is a risk of cancer. Nail polish is made of nitrocellulose, mixed with acetone, ethyl acetate, ethyl lactate, phthalic acid tincture, plasticizer, chemical dyes and other chemical solvents. When applied to nails, it can make them bright and moist and will not fade for a long time. Among them, there is a chemical called phthalate, which has a high content. Mainly softening, this substance will enter the human body through the respiratory system and skin. In fact, most of these raw materials are benzene-containing compounds, which are volatile and will have adverse effects on the human body after eating or inhaling, ranging from gastrointestinal discomfort and loss of appetite to vomiting and anorexia. Pay special attention when using. In addition, some studies have shown that some inferior nail polishes contain up to 80% carcinogen phthalate, which will enter the human body through the respiratory system and skin. If used in excess, it will increase the risk of breast cancer in women. Another survey shows that nearly 90% of nail polish has no Chinese logo on the packaging and label. The most prominent problem of these unqualified nail polishes is the use of prohibited pigments, which contain a large number of fluorescent agents that may cause cancer. In addition, many skin polishes and nail enhancers used in nail art are unknown and may contain toxic substances. Because nails are easy to absorb foreign substances, long-term use of nail polish with excessive heavy metals such as lead, arsenic, mercury and benzene may lead to chronic poisoning and even cancer. 4. It can lead to abortion and teratogenesis, and pregnant women have nails. Beware that nail polish can cause fetal malformation. Nail polish generally contains a substance called "phthalate", which is likely to cause fetal malformation and abortion. Phthalate ester is a colorless and odorless oily liquid with good volatility, which can make nail polish more uniform and lasting. It can enter the human body through the skin, respiratory tract and digestive tract and accumulate in adipose tissue, which is not easy to be excreted. If the residual concentration of this substance in human body is high, it will do harm to liver, kidney, cardiovascular system and reproductive system, and affect the endocrine function of human body. Long-term use by pregnant women can lead to fetal genital malformation. 5. The first step of nail infection with paronychia is usually to remove the small skin on the nail, remove or push off the small skin on the customer's nail, that is, file off the skin near the moonlight or even remove it, which is harmful to the nail itself. Many ladies who like manicure find that after several manicures, they can't stop. Because your real nails have become "disgusting" Thickened nails can only be filed thin to maintain the "image". In addition, regular manicure can also cause nails to turn black and gray, so they have to be covered with thick nail polish. What's more, because of the constant oiling to cover up the deformed nails, it leads to a vicious circle, and finally the finger flesh around the nails is red, swollen and suppurative. This is mainly because the nail matrix loses protection after removing or pushing the small skin of the nail, which is easy to make the subcutaneous tissue red and swollen. If the infection is serious, it will fester quickly and form paronychia. If it recurs, it will eventually become chronic paronychia. In addition, there is a layer of enamel-like substance on the nail surface, which can protect the nail and become a barrier. After the nail surface file is thin, the protective effect is weakened, and bacteria, fungi and microorganisms can easily infect the human body. I hope you can pay attention, health is important!
