2. The harm of manicure
1, inferior nail polish can cause chronic poisoning and even cancer.
The most prominent problem of many unqualified nail polishes is the use of prohibited pigments, which contain a large number of fluorescent agents that may cause cancer. Many skin creams, nail enhancers and so on are not clear. Nails absorb foreign objects easily. 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.
In addition, many nail polishes contain a chemical called phthalate, which will enter the human body through the respiratory system and skin. If used frequently, it will increase the risk of breast cancer in women. Therefore, nail polish must be purchased qualified and the quality is guaranteed.
2, toxic nail polish, will cause miscarriage or fetal malformation in pregnant women.
Pregnant women or pregnant women need to be highly alert to the potential harm of nail polish to the fetus. Most inferior nail polishes contain a substance called "phthalate", which has a great influence on the fetus and is likely to lead to 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 also enter the human body through the skin, respiratory tract and digestive tract. If the residual concentration of this substance in human body is high, it will do harm to liver, kidney, cardiovascular system and reproductive system. Long-term use by pregnant women will affect the development of baby's reproductive organs, especially baby boys, who may have impotence or infertility in adulthood.
3, nails are too thin, easy to get paronychia.
The first step of manicure is usually filing, filing and filing. The skin near the moonlight on the nail is filed thin or pushed back, or even removed. Excessive thinning of the nail is a kind of harm to the nail itself. 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.
Ladies who often do manicures will find that after several manicures, they will continue to do it, because their real nails have changed beyond recognition, and they can only continue to file thin to maintain a beautiful image. Regular manicure can also cause nails to turn black and gray. If the nail is excessively thin, the nail matrix will lose its protection and easily make the subcutaneous tissue red and swollen. If the infection is serious, it will fester quickly and form paronychia.
4, nail tools are unsanitary and easy to infect diseases.
Hygiene of nail tools is another health hazard. Nowadays, many nail shops are very simple. The nail tools provided by these nail shops can't guarantee cleanliness, and the towels, tweezers, scissors and other tools used can't be completely disinfected. 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. Especially in the process of peeling off dead skin, sharp tools are easy to destroy skin tissue, and if not disinfected, it is likely to cause cross infection.
5, long-term nail patch, nail damage
Everyone likes to use imitation nails, which are common nail stickers. When making this kind of nail, special glue will be used. It is relatively strong, and if it is taken out later, it is easy to cause nail cracking or even bleeding if it is not handled properly. Moreover, covering the surface of nails with patches is not conducive to the normal breathing of nails. Long-term patches will cause natural nails to dry up, yellow and easily break.
