Official title
Comparison of Objective Skin Barrier Function Parameters Between Women Who Use and Women Who Do Not Use UV Nail Lamps for Nail Treatments
Overview
The goal of this observational study is to compare objective parameters of skin barrier function between healthy adult women who regularly use UV lamps during nail treatments and women who do not use UV lamps. The main questions it aims to answer are: * Do women who regularly use UV lamps for nail treatments show differences in skin barrier function compared to women who do not use UV lamps? * Are transepidermal water loss, skin hydration, and erythema associated with regular exposure to UV lamps used for nail treatments? * Does the duration of UV lamp use influence skin barrier function parameters? Researchers will compare women who regularly use UV lamps during nail treatments with women who have natural nails and do not regularly expose their hands to UV lamps. Participants will: * Attend a single study visit. * Complete a short questionnaire regarding nail care habits and duration of UV lamp use. * Undergo non-invasive measurements of skin barrier function on the hands, including transepidermal water loss, skin hydration, and erythema assessments.
Primary outcome measures
- Change in Transepidermal Water Loss (TEWL) [Time frame: Day 1 (single study visit)]
- Change in Skin Hydration [Time frame: Day 1 (single study visit)]
- Change in Skin Erythema [Time frame: Day 1 (single study visit)]
