How safer personal care product selection can reduce chemical exposure

In an interview with Contemporary OB/GYN, Lariah M. Edwards, PhD, associate research scientist at the Columbia University Mailman School of Public Health, discussed how selective product choices can reduce exposure to harmful ingredients commonly found in cosmetics and toiletries.^1,2

A growing body of evidence highlights personal care products as a significant source of chemical exposure, particularly for women and women of color, who tend to use these products more frequently than other groups. Edwards emphasized that many personal care products contain chemicals such as phthalates, parabens, and benzophenone-3 (BP-3), which are linked to hormone-disrupting effects. Research in both animals and humans has demonstrated associations between these substances and a range of adverse health outcomes.

For example, phthalates—often used to preserve fragrance and flexibility in products—are well-established hormone-altering agents connected to obesity, diabetes, and reproductive health concerns. Parabens, widely used as preservatives to prevent microbial growth in shampoos, lotions, and other products, have been implicated in metabolic disruption and potential carcinogenic effects. While these chemicals serve functional purposes, their long-term health risks are concerning.

Edwards explained that although regulatory protections are still insufficient, individual consumers can take steps to lower their personal exposures. Choosing products labeled “fragrance-free” or specifically marketed as free from phthalates, parabens, and related compounds can make a measurable difference. In fact, her team’s research found that women who intentionally avoided these ingredients showed lower levels of the chemicals in their bodies, providing clear evidence that consumer choices can reduce internal exposure.

Reducing contact with these chemicals may, in turn, improve health and well-being by lowering risks associated with endocrine disruption, metabolic disease, and reproductive complications. Edwards stressed, however, that while informed shopping can help, responsibility should not fall entirely on consumers. Access to safe, affordable, and effective products should be guaranteed across all price points, and stronger regulations are needed to prevent harmful chemicals from being included in personal care products in the first place.

Until such policies are enacted, Edwards encourages consumers to shop selectively when possible, as avoiding specific ingredients can reduce toxic burden and support long-term health. Her key takeaway is 2-fold: making mindful choices can have immediate benefits, but broader systemic changes are necessary to ensure equitable access to safe personal care products for everyone.
