Age-related variations in stratum corneum hydration in the foot.

Objective: The aims of the study are to identify which region of the foot has lower hydration according to age, measure the variation in the level of stratum corneum hydration of the foot across the a wide age range, and examine hydration differences of the foot according to gender.

Study Design: A descriptive observational study was conducted to assess stratum corneum hydration of the foot among 504 participants recruited between November 2023 and March 2024.

Main Outcomes Measures: Stratum corneum hydration assessment was conducted using a Corneometer 825® probe at 10 specific points on the foot.
