Illustrating Skin Hydration by Capacitive Contact Imaging after Frequent Hand Disinfection

In addition to established parameters such as pH, transepidermal water loss (TEWL) and dermatological assessments, the effects of a two-week application of a hand disinfectant foam on skin condition were investigated. Regular daily use of the product resulted in an improvement in skin hydration without any intolerance. The results obtained by CCI and corneometry were consistently comparable and showed a significant increase in skin hydration after the two-week application period. CCI visualised the increase in skin hydration, demonstrating its potential as an additional method to assess and demonstrate the effect of hand hygiene products on skin health [1].
