Cosmetic-derived endocrine disruptors induce metabolic dysfunction beyond reproductive effects

Abstract
While endocrine disrupting chemicals (EDCs) in cosmetics are recognized for reproductive health effects, their broader metabolic impact remains understudied. This study investigated metabolic dysfunction associated with cosmetic-derived EDC exposure in reproductive-age women. We examined fasting blood glucose, insulin resistance markers, and metabolic syndrome prevalence in 126 women: cosmetic users with PCOS (n=42), cosmetic users without PCOS (n=42), and non-cosmetic-using controls (n=42). Metabolic parameters were correlated with hormonal profiles and androgen receptor gene expression. Findings showed that fasting blood glucose was significantly elevated in cosmetic users with PCOS (103.52±11.50 mg/dL) and without PCOS (99.40±22.82 mg/dL) compared to controls (80.19±9.51 mg/dL; p<0.001). Insulin resistance, assessed by HOMA-IR, was present in 67% of PCOS cosmetic users and 43% of non-PCOS users versus 12% of controls (p<0.001). Metabolic dysfunction correlated with androgen receptor upregulation and testosterone levels, suggesting shared pathogenic mechanisms. Hence, cosmetic-derived EDC exposure induces metabolic dysfunction independent of PCOS status, representing a novel pathway linking environmental chemicals to cardiometabolic disease risk in women.
