A new study found for the first time that common skin care products used by young children may increase their exposure to hormone-disrupting chemicals.
The results may help guide parents to limit their children's exposure to toxins that could harm their development, Michael Bloom, study leader and professor at George Mason University's College of Public Health, told The Epoch Times.
Phthalates, often found in skincare products, can disrupt the endocrine system, potentially interfering with hormones. These chemicals may be added to skincare products to improve absorption, prolong fragrances, or make the product more lubricating.
"While the evidence is not definitive at present, the potential hazardous human health effects ... demands a precautionary approach," said Bloom, who has worked on several other studies involving phthalates and other potential health hazards.
As part of the clinical study, parents were asked to list skin care products that had been applied in the 24 hours before the examination. These products included soaps, lotions, shampoos, cosmetics, and sunscreen. The researchers noted frequent use of skin care products among participants during this period, with most children using at least one type of soap and lotion.
The researchers also surveyed the parents about their children's racial and ethnic backgrounds. Black participants had the highest rate of phthalates in their urine, possibly because of their choice of products and frequency of use.
"Consumers can check product labels to identify potentially harmful ingredients in skin care products and refer to websites that provide detailed information about commercially-available skin care products," Bloom said.
Phthalates can also migrate from plastic packaging into products, Bloom said, suggesting that policy changes may be needed to limit children's exposure.
"These studies were often conducted at very high doses of phthalates, greater than those typically experienced by human populations," Bloom said. "Still many observational studies in human populations worldwide have reported associations between exposure to some phthalates and neurocognitive problems, reproductive problems, changes in hormones, metabolic disease, and other adverse health effects, suggesting that there are toxic effects," he added.
The current study's results may inform policymakers, doctors, and parents to "help limit children's exposure to developmental toxicant," authors of the current study wrote.
