Skincare habits and rosacea in 3,439 chinese adolescents: A university-based cross-sectional study

Abstract

The pathogenesis of rosacea remains unclear but has been reported to correlate with skin barrier function. The objective of this study was to elucidate the skin-care habits of Chinese adolescents and determine the relationship between skincare habits and rosacea. A university-based cross-sectional investigation inclu-ded 310 rosacea cases and 3,129 healthy controls who underwent health examinations and completed a questionnaire about daily skincare habits. Fitzpa-trick skin phototype IV is a protective factor against rosacea (adjusted adds ratio (aOR) 0.40; 95% con-fidence interval (CI) 0.22–0.72). Long bath duration (≥ 11 min, aOR 2.60; 95% CI 1.01–6.72) and frequent use of facial cleansers (≥ 2 times/day, aOR 1.70; 95% CI 1.17–2.36) were positively associated with rosa-cea, but bath frequency (p = 0.22), water temperature (p = 0.53), and sun protection (p = 0.65) were not associated with rosacea. Inappropriate skincare habits, including extended bath durations and frequent use of facial cleansers, significantly increase the risk of rosa-cea in Chinese adolescents.
