High-osmolality personal lubricants, often exceeding 10,000 mOsm/kg, can cause tissue dehydration, damage the epithelial lining, and increase susceptibility to bacterial vaginosis and STIs. To minimize these risks, the World Health Organization recommends choosing lubricants with an osmolality below 380 mOsm/kg, ideally avoiding ingredients like glycerin and chlorhexidine.
