claim that these chemicals pose a threat to human health.
A dermatology and beauty specialist at the LewisGale Medical Center in Salem
discussed common cosmetic ingredients and weighed whether they might pose long-term health risks.
“Parabens are chemicals that help preserve cosmetics,” Kirk said. “They are designed to ensure your safety by preventing the growth of harmful bacteria and mold.”
She went on to say that parabens are very common. They can be found in cosmetics, moisturizers, shaving products and sunscreens, to name a few.
They are absorbed through your skin, so they are often used. Research estimates that about 99% of people in the United States have parabens in their systems.
“It is important to use these products as instructed and read labels like all cosmetics,” Kirk explained. Parabens may be listed under various names, usually ending in “-paraben”, for example:
Is paraben associated with cancer? There is insufficient evidence to claim that these chemicals pose a threat to human health.
The US Food and Drug Administration (FDA) did not supervise cosmetic preservatives before they were put on the market, and manufacturers themselves usually conduct safety tests. However, the FDA did review any research on preservatives. If researchers think that the risk of a substance is too great, FDA will notify the public. So far, parabens have not attracted FDA’s attention.
The American Cancer Society (ACS) pointed out that parabens may have weak effects similar to estrogen. Estrogen is a hormone involved in female reproduction, and its high levels may play a role in the development of breast and ovarian cancer.
In rodent studies, paraben exposure is associated with weight gain and ovarian changes. For male rats, it interferes with the production of sperm and male hormones. Other laboratory studies have shown that parabens may promote weight gain, but there is insufficient evidence to know whether they will have a real effect on body weight.
Despite laboratory findings, research has not shown a direct link between parabens and any health problems.
Formaldehyde is a preservative sometimes found in cosmetics, baby lotions and hair care products. According to research involving a large number of contacts, this is a known carcinogen. The content of American products is very small and can be considered safe, but it may cause skin allergic reactions in some people.
Some hair care products (such as hair conditioners) may contain methylene glycol, which releases formaldehyde into the air when heated. Again, the FDA will not approve hair and cosmetics before they are marketed. But the organization does notify the public and warns companies about whether their products may harm consumers. The FDA has not restricted the use of formaldehyde in cosmetics, but it has issued a warning about methylene glycol.
Since methylene glycol is heated in the hair salon (dried, curled, straightened, etc.), customers and hair salon staff may inhale the released formaldehyde. This level of exposure exposes them to the following risks:
Nervous system problems such as headaches and dizziness
Difficulty breathing or chest pain
feel sick and vomit
According to research by the American Occupational Safety and Health Administration (OSHA), inhaled formaldehyde is also associated with nose and lung cancer.
If you are worried about inhaling formaldehyde or methylene glycol at home, FDA recommends checking the product label before purchasing. Also look for formalin (a similar compound), and pay attention to these formaldehyde-releasing ingredients:
To avoid showing their face at the hairdresser, ask them to skip the hair smoother. You can call to confirm that the product does not contain formaldehyde.
“Talc is a mineral that we have used for many years,” Kirk said. It can be found in baby powder, dry cleansing shampoo, foundation and makeup powder. Because it absorbs moisture, it is often used in oily skin and hair type products.
“Naturally, some talc powder contains asbestos,” Kirk said. Asbestos is a known carcinogen or carcinogen. If talcum powder containing asbestos is placed directly on the genital area or sanitary napkin, it may increase the risk of ovarian cancer. ”
However, the FDA does not allow asbestos in cosmetic talc powder. From 2009 to 2010, the organization commissioned a study to determine whether the substance has been successfully removed from US cosmetics. Of the 34 products surveyed, the researchers did not find asbestos fibers.
“Despite these results, the FDA does not say that all products containing talc do not contain asbestos,” Kirk warned. Only four of the nine U.S. talc suppliers participated in the study, so not every product has been tested.
