Critical Exposure Risk — Why This Product Category Matters

Personal care products are applied directly to skin — the body's largest organ — and often left on for extended periods. Many contain microplastics (as exfoliants or film-forming agents), phthalates (as fragrance carriers), and PFAS (in long-wear formulations). Daily use compounds exposure significantly.
