Common Chemicals of Concern: Parabens
Check the label on your shampoo, your lotion, your foundation, or the pain reliever in your medicine cabinet. There is a reasonable chance you will find a paraben.
Parabens are a family of endocrine-disrupting compounds used as preservatives and antimicrobials. They show up in food, pharmaceuticals, personal care products, cosmetics, and adhesives. They are effective at what they do, which is why they are everywhere.
The concern comes from the fact that parabens are mildly estrogenic, meaning they can mimic estrogen in the body. Endocrine disruption is a serious area of study when it comes to breast cancer risk.
Here is the part that matters most: research on the health impacts of parabens is lacking. Parabens are not currently regulated or classified by the International Agency for Research on Cancer, the National Toxicology Program, or the Environmental Protection Agency.
That is not reassurance. That is a gap. Widespread exposure to a compound with estrogenic activity, and not enough research to say what it means.
If you want to reduce your exposure while the science catches up, read labels on personal care products, cosmetics, and over the counter medications, or look for products labeled paraben-free.
