Potential health risks from microplastics in "leave-on" cosmetics like sunscreens and moisturizers are understudied, leaving gaps in understanding and regulation.
Pamela Ferdinand reports for U.S. Right to Know.
In short:
- New studies emphasize the need for urgent research on microplastic pollution from "leave-on" products, which are largely ignored by current regulations.
- Researchers found that most microplastic testing focuses on "rinse-off" products like soap, while complex formulations in "leave-on" items complicate assessments.
- Experts call for comprehensive testing of all cosmetic products and improved global regulations to address the widespread environmental contamination.
Key quote:
"Environmental contamination could double by 2040 and widescale harm has been predicted."
— Prof. Richard C. Thompson, marine scientist
Why this matters:
Microplastics are pervasive in the environment and have been found in human tissues, raising concerns about long-term health effects. As cosmetic use is widespread, addressing regulatory gaps could significantly reduce exposure risks and environmental damage.
