Impetigo is a bacterial infection of the skin that shows up as blisters usually around the mouth. For prevention, drink one teaspoon of structured silver twice a day. If you already are suffering from impetigo, drink two teaspoons twice a day and, more importantly, apply the gel topically one to four times a day. When impetigo is kept moist with silver gel, it can spread less and improve much quicker. Since impetigo is contagious you will want to apply the structured silver gel to your hands as well in order to prevent contaminating yourself or others.
