Does driving with UVA exposure affect facial skin hydration on the left vs right cheek in Florida drivers

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study will enroll eighty female drivers aged 25–65 who reside in Florida. At a single visit, researchers will measure skin hydration at the left cheek, right cheek, and forehead using a bioimpedance device, and collect information on driving habits, sun protection, and skin history. The aim is to see if chronic UVA exposure from driving is linked to hydration differences between cheeks, with the forehead serving as a symmetrical control. Participants must meet criteria related to driving frequency, residency, and consent, and will be excluded if there is sun-screening bias on the left side, existing facial skin disease, or recent cosmetic procedures. This is an observational study without an interventional treatment, focusing on descriptive associations.
