1, make nails yellow and dull.
Nail polish has a variety of beautiful colors because of the addition of a large number of pigment components, including various mineral pigments and synthetic pigments. These pigments slowly attach to nails, causing them to become darker and dimmer. The darker the color of nail polish, the more obvious the phenomenon of pigment precipitation.
2, make nails brittle, layered fracture, slow growth.
Continuous application of nail polish will hinder the "normal breathing" of nails and destroy the keratinocytes of nails. Because of the lack of oxygen caused by poor breathing and the chronic corrosion of nail polish, nails naturally become thinner and thinner, easily broken and grow slowly.
3. The corrosion of nail substance leads to the separation of nail and nail bed.
It is easy to corrode nail polish. Many people use nail polish, which causes the nail to separate from the skin of the nail bed below, causing the nail to peel off and become arc-less. Long-term use causes nails to become thin and brittle, become unhealthy, and are more prone to diseases such as onychomycosis.
4. The taste of nail polish is toxic and makes people dizzy.
Some nail polishes contain a large amount of acetone and ethyl acetate, which is characterized by its volatility, producing a dizzy pungent smell (its volume will expand by 65,438+0,000 times after volatilization), and it is very irritating to mucous membrane and nervous system.

5. Dry, inflamed and prickly fingers.
Incomplete disinfection of nail tools will indirectly cause fungal infection between nails. On the other hand, chemical solvents in nail polish can irritate the skin around nails. Let the keratin on the edge of the finger harden, and touch a slight injury in the process of manicure, which will easily lead to inflammation, dryness or barbs, and even lead to paronychia.
6, can cause abortion.
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 will affect the development of baby's reproductive organs, especially baby boys, who may have impotence or infertility in adulthood.
7. It may cause cancer.
The reason why nail polish is bright and colorful is that it contains a lot of chemical components, which can make the color of nail polish varied, and at the same time, it can ensure that nail polish will not fall off for a period of time. Experts remind that the solvent components of ordinary nail polish include artificial pigments, which are usually toxic and harmful substances, and some even contain heavy metal elements. If it is used for a long time and absorbed by the human body, it is likely to cause great harm to the human body. Benzene and formaldehyde are the most powerful, followed by acetone and ethyl acetate. If smeared or exposed to these substances for a long time, there is a risk of cancer.
The latest research found that nail polish also contains Sudan red, which is very toxic. If it is used for a long time, it will lead to the gradual accumulation of toxins in the human body, which will lead to the danger of poisoning and cancer.
