In recent years, with the gradual strengthening of people's health awareness, more and more foods, medicines and cosmetics containing carcinogens have been exposed one by one. The topic of lipstick causing cancer has also caused anxiety and panic among many girls.
So is lipstick harmful to human body? What are the hazards? What are the precautions in daily use?
At present, the national control standards for heavy metals are very strict, and it has long been forbidden to add heavy metals such as lead, mercury and arsenic to cosmetics. Therefore, manufacturers will not deliberately add heavy metals such as lead to lipstick.
Blood lead content ≥2.9μmol/L(600μg/L) is one of the conditions for diagnosing mild lead poisoning, and the total blood lead content of mild lead poisoning is about 2.7mg. The US Food and Drug Administration (FDA) stipulates that the lead standard of candy is 0. 1ppm (equivalent to 1mg/kg), and the lead content of a lipstick (about 5g) that meets the FDA standard is 0.0005mg.
Suppose you eat the whole lipstick, and all the lipstick you eat is absorbed into your blood. Only 5400 lipsticks can cause mild lead poisoning. According to a lipstick, it can be used for at least 2 months. You have to eat 10800 months, which is 900 years! 900 years!
Therefore, you don't have to worry that eating lipstick will lead to lead poisoning.
The main raw materials of lipstick include colorant, filler, wax, oil, pearlescent agent and essence. In order to increase luster, there are preservatives and antioxidants butyl hydroxyanisole and butyl benzyl phthalate in lipstick, which have long been proved to be carcinogens.
According to statistics, about 10% of women who wear lipstick will have lip allergy symptoms such as chapped lips, swelling, itching, exfoliation of epidermis and slight pain, which is what we often call "lipstick disease". If this phenomenon occurs repeatedly for many years, it will really increase the possibility of cancer in the lips.
The dye content of most lipstick products far exceeds the allowable range of food. Organic dyes in lipstick may be transformed into mutagens under ultraviolet irradiation, which makes cells mutate, which is a suspicious cause of lip cancer.
1. Don't buy inferior lipstick. Be sure to buy lipstick from regular manufacturers through regular channels. The safety of the three products is not guaranteed.
2. Although applying lipstick for a long time will not lead to lead poisoning, try not to eat lipstick in your stomach. Teenagers, children and pregnant women should be more cautious.
3. It is not recommended to wear lipstick for a long time. Although lipstick can make lips look tender, long-term use can also cause side effects such as chapped lips, swelling and itching.
4. It is best not to apply it directly to your lips. You can apply a layer of vaseline or lip balm to your lips first, so as to avoid direct contact between lipstick and your lips.
Try it before buying to see if it is allergic. Everyone's skin sensitivity is different, so it's best to try it locally on the lips before buying to see if there are any adverse reactions.
A touch of bright lipstick can outline the beauty of the finishing touch between square inches. As long as the lipstick you buy is a product that meets the national standards and is produced by a regular manufacturer, please feel free to use it to promote beauty and charm yourself.
