Chemicals in Cosmetic Products Might Harm Women’s Hormones

Researchers found a link between chemicals in cosmetic products and changes in reproductive hormones, according to a study published on September 13, 2018.

This study was conducted by the researchers at the George Mason University. Assistant Professor of Global and Community Health Dr. Anna Pollack and colleagues found links between chemicals used in cosmetic and personal care products and changes in reproductive hormones. This study is the first to study about the association between chemicals and women hormone.

In the study, 509 urine samples were collected from 143 women aged 18 to 44 years, free of known chronic health conditions and birth control to be measured for environmental chemicals that are found in personal care products, such as parabens, which are antimicrobial preservatives, and benzophenones, which are ultraviolet filters.

This multi-chemical approach more closely reflects real world environmental exposures and shows that low-level exposure to mixtures of chemicals also might affect reproductive hormone levels. The relation between certain chemical and UV filters with decreased reproductive hormones in multi-chemical exposures while association of others with increase in other reproductive hormones is another major finding of this study.

Pollack said, “What we should take away from this study is that we may need to be careful about the chemicals in the beauty and personal care products we use. We have early indicators that chemicals such as parabens may increase estrogen levels. If this finding is confirmed by additional research, it could have implications for estrogen dependent diseases such as breast cancer.”
