Driving Time and Facial Skin Hydration Asymmetry in Florida Drivers (NCT07764809)
Driving Time and Left-Cheek Skin Hydration Asymmetry in Florida Residents: An Observational Study on Cumulative UVA Exposure Through Vehicle Side Windows
🩺 Plain-English Summary (8th-Grade Level)
his observational study examines whether time spent driving is associated with differences in skin hydration between the left and right cheeks in female drivers residing in Florida. In left-hand-drive vehicles, the driver's left cheek is chronically exposed to ultraviolet A (UVA) radiation through the unshaded side window during every daytime driving episode. A prior study by IAS Skin Care (NCT07564869, n=30) found that the left cheek was less hydrated than the right cheek in 60% of participants, suggesting a possible effect of driving-related UVA exposure on facial skin hydration asymmetry. Eighty female drivers aged 25-65 years residing in Florida will be enrolled. At a single visit, skin hydration will be measured at three facial zones (left cheek, right cheek, and forehead as a symmetrical control zone) using the BT-Analyze bioimpedance device. Participants will complete a structured questionnaire on driving habits, sun protection practices, and skin history. The primary outcome is the Hydration Asymmetry Index (HAI = right cheek minus left cheek BT-Analyze score). Associations between driving time, cumulative driving exposure, window tinting, sunscreen use, and HAI will be examined using Spearman correlation, Mann-Whitney U tests, and multiple linear regression.
