The average American lives in a perpetually dehydrated state of being. The military says that one of the things they have to drill in basic training is to acclimate the recruits to the idea of keeping their bodies hydrated.
First off, your body needs water to do anything. The water should be safe for life. Most tap water doesn't meet this criteria, as the chlorine and fluoride render it unsafe for man or beast.

Next up skin and organs must be built from the inside out, so it is vital that a person get enough vitamins A, C, E and zinc to make good skin. The beauty industry will sell you stuff with these constituents in creams and potions, but getting them internally is best.

Some of that could be due to the body not being able to produce the other compounds.
If one is well hydrated, and nutritionally sound, and keeps the treated area clean and dry for 24 to 72 hours, one should do just fine.
