The excessive use is the question. We use alcohol on our hands after shopping or being in town. Normally you do not need alcohol for disinfection if you have access to good soap and water. Any virus or bacteria has a fatty cell wall and the soap can break the cell wall down as well, not as fast, as any locally found alcohol or hand cleaner.
The use of alcohol has never been known to do anything to your skin except to dry it out and make it sometimes start itching. After using alcohol to disinfect, you should cream your hands again.
Alcohol consume does indeed tho have an effect on your blood circulation on the mouth and throat, makes you get old faster with wrinkles, often causes the user to regurgitate and creates the problem with their teeth being lost from the acid (reflux) eating their gums and loosening the teeth to enable them to fall out too soon.
Hope the answer helps a bit, Gary
