Pure alcohols can slightly dry out the skin 1. Well-formulated hand disinfectants, however, contain caring substances that prevent the skin from drying out even during intensive use 2, 3. In addition, alcohol-based hand disinfectants do not affect the natural hydrolipid film on the skin.
When washing hands, lipids are removed from the skin. Thus, washing hands dries out the skin significantly more. Especially in winter, the skin can feel dry even with frequent hand disinfection, which is primarily related to the season and the temperature. In this case, hands should be creamed regularly.
