Hello,
Most hand sanitizers contain 60-80% alcohol. Alcohol destroys organisms including bacteria, fungi, protists, and enveloped viruses by breaking down the plasma membrane. In recent years, microbial communities on the skin, in the airways, and in the gut have been shown to play an important role in health. Does daily use of hand sanitizer negatively impact the diversity and strength of the hand microbiome? If so, what are the implications of this to overall health? Do skin microbes play beneficial roles such as helping to prevent transmission of other pathogens?
Thank you.
