Structure and function of nails
Speaking of nail art, I have to mention the normal structure and function of nails first.
Nails are a normal extension of the skin, an appendage structure of the extremities, and like hair and skin, are mainly composed of keratin. The growth of nails is caused by the secretion of keratin by the mother of the nail.
The nail mother is located under the skin behind the nail and is protected by the nail epithelium. Part of the newly grown nail is also hidden under the root skin, called the nail root.
The body of the nail is called the nail body and is made up of keratin. At the base of the nail body, the area just through the skin is a white half-moon shape, called the nail half-moon.
The skin tissue that is closely connected to most of the underneath of the middle of the nail body is called the nail bed. The nail bed is rich in capillaries, giving the nail a pink appearance.

There are a small amount of skin covered on the left and right sides of the nail body, called the nail border. The separation of the nail body from the nail bed at the apex is called the free margin.
Healthy nails can grow 0.1 mm per day, with an average of 6~9 months to replace one deck. The outermost surface of the nail is smooth, which is the "credit" of the lipid membrane of the outermost layer of the nail and the keratin of the layered structure. The function of nails is to protect the skin of the finger extremities while helping the hand to do delicate work.
Now for girls, there is also more function to show "beauty", just like makeup, nail art - is the art of decorating the surface of nails, and it is also one of the ways for girls to express themselves.

Manicure and its hazards
Needless to say, fashionistas are familiar with the common steps of nail art. The most common steps are nothing more than disinfection, softening, trimming, sanding, nourishing (nutritional oil), nail polish (or nail glue) and light.
Occasional manicurs undoubtedly add a colorful little interest to monotonous daily life, but frequent nail art, coupled with limited hygiene conditions in nail salons, then nail art will cause many disease problems.

- One of the dangers of nail art: infection
The process of trimming, peeling dead skin, and pushing the nail epithelium will use files, finger pliers, etc., these appliances are often used by many people, and the manicurist will only use 75% alcohol to briefly disinfect before using it to customers, which may not achieve the effect of sterilization. Someone else's bacteria or fungi may bring you cross-infection.
And the process of removing dead skin and pushing the nail epithelium will inevitably hurt the normal perinail structure, so many girls report that doing perfect nails, periungual redness, pain, and even abscesses, this is paronychia is right. There are also girls who have encountered minor wounds during nail trimming, giving fungus invasion and the opportunity to root in the nails, and finally onychomycosis (onychomycosis).

The girl I met before, accidentally infected after nail art, she was in a panic, she "handled" out the pus under the nail, the nail was on the string, had to pull, for the nail art and got the "nail pulling" experience package, it can be said that it is a disaster without vain.

- The second harm of nail art: thinning of nails
In order to make nail glue and jewelry firmly stick to the surface of the nail, many times the manicurist will continue to polish the surface of the nail until the surface is rough, which is conducive to sticking. The process of continuous polishing is a process of constantly damaging the lipid membrane and keratin on the surface of the nail, occasionally once or twice will not have much effect, but the consequence of long-term polishing is that the nail becomes thin and easy to break and damage.
Some researchers have tested the average thickness of nails before and after nail art, the average thickness can be reduced from 0.59 mm to 0.30 mm, which is half the full half, and the thickness of the nail becomes thinner and easy to break. In the long run, it will affect the health of the nails and also affect the delicate work we can do.
- The third harm of nail art: dermatitis
Nail polish and nail glue in a variety of ingredients, the composition of nail polish, 70% ~ 80% is volatile solvents, about 15% is nitrocellulose, and a small amount of oily solvents, camphor, titanium dioxide and fat-soluble pigments.
The main components of nail polish are natural resins as well as some color pigments. However, methyl methacrylate in the formale resin can cause contact allergic dermatitis in some people.

- The fourth harm of nail art: poisoning, cancer
The relevant information of the US Environmental Protection Agency pointed out that among the common 20 kinds of organic components in nail polish or nail gum, 17 are harmful to the respiratory tract, of which dibutyl phthalate (DBP), toluene, formaldehyde are the most harmful to people, known as the three major poisons, teratogenic and carcinogenic fertility have a great impact.
In addition, some nail polish or nail rubber products are unqualified, containing heavy metals such as lead, arsenic, mercury, etc., and long-term use of these products containing heavy metals will cause chronic poisoning and even the risk of cancer.
Some people also say that the illumination problem of nails will also cause cancer, here to refute the rumor, the light used in nail shops is part of LED visible light, part of ultraviolet light, with UVA as the main component. The function is to speed up the drying of nail rubber.
There is no problem with visible light, UVA in ultraviolet light only has a carcinogenic risk under the premise of long-term large exposure, and the UVA exposure of nails is very low, and studies have shown that the risk of carcinogenesis is extremely small.
