These polymers prevent and inhibit microbial infestation. The significance of these new polymers is that they are non-leaching and non-migrating. The primary mode of extermination is physical and not chemical. As the skin is exposed to germs, bacteria and viruses they are killed by the polymer's surface composition which acts like a sword that effectively skewers and ruptures the microbes outer cellular wall and keeps the skin germ free. Once the Perfect Foot Defense is applied to the skin it attaches and will continue to protect against foot disease for hours. Two applications a day should help to exterminate unwanted foot problems.How do I use this Perfect Foot Defense? It will dry in a matter of seconds! NO RINSING REQUIRED & TOWELS NEEDED!
