Study Links Children’s Skin Care Products to Hormone-Disrupting Chemicals

A new study has found that personal care products used by children may expose them to hormone-disrupting chemicals, sparking concerns over the potential health effects of everyday items like lotions, shampoos, and soaps. These chemicals, particularly phthalates, are linked to disruptions in the endocrine system, which controls hormone regulation. Phthalates, commonly added to products to enhance fragrance or absorption, have been shown to interfere with hormones, posing a potential risk to children whose bodies are still developing.

The research, led by Michael Bloom, a professor at George Mason University, involved 630 children aged 4 to 8 from across the U.S. Each participant underwent a urinalysis to detect phthalate byproducts, and parents provided a list of the skin care products applied in the previous 24 hours. The study found significant associations between recent product use and higher concentrations of phthalates, reinforcing the idea that everyday items are contributing to children's exposure to these chemicals​.

Phthalates are known for their ability to mimic or block hormones, and their presence in children’s bodies raises concerns about potential developmental issues. According to Bloom, past research has shown that phthalates can affect body composition, neurodevelopment, and immune function in children. While the current study doesn’t definitively prove these products cause harm, it suggests the need for precaution. Bloom stated, "The potential hazardous human health effects … demand a precautionary approach," indicating that parents should be mindful of product ingredients and opt for safer alternatives where possible.

The study also highlighted disparities in exposure across different demographic groups. Black children were found to have higher phthalate levels in their urine, possibly due to the specific products marketed to and used more frequently by this community. This finding raises additional concerns about the marketing practices of personal care companies and the ingredients they include in products intended for communities of color​.

While phthalates are regulated by the U.S. Food and Drug Administration (FDA), these regulations have significant gaps. For instance, while product labels must declare ingredients, they do not have to specify the chemicals used in fragrances or flavors, making it difficult for consumers to know if a product contains phthalates. The FDA’s regulations are notably less stringent than those in the European Union, where over 1,300 harmful chemicals have been banned from personal care products, compared to just 11 in the U.S.​.

Experts recommend several steps to reduce children’s exposure to phthalates. First, parents can opt for products labeled "phthalate-free" or "paraben-free," though these claims are not always reliable. Checking ingredient lists and avoiding heavily scented products can also help. Dr. Rocco, an endocrinologist, suggests that families should minimize the use of personal care products in general and look for natural, organic options that don’t contain harmful chemicals. DIY alternatives, such as homemade lotions and soaps, are another way to avoid potentially harmful ingredients.

Although phthalates typically leave the body within days, experts warn that consistent exposure, particularly in children, could lead to long-term health consequences, including reproductive issues, early puberty, and even an increased risk of breast cancer in girls. These concerns are compounded by the fact that children are more vulnerable than adults due to their developing organs and increased skin absorption.

This study underscores the growing awareness of the risks posed by endocrine-disrupting chemicals and the urgent need for stronger regulatory measures to protect children. With consumer products so saturated with these chemicals, it’s becoming increasingly difficult for parents to make informed decisions without clearer labeling and stronger oversight from the FDA.
