Howcome you get squeaky-clean skin with a bar of soap but not shower gel?

To continue the first answer- And that reaction that gives you "squeaky clean" skin, is really the chemicals over drying your skins natural oils.

A bar of soap contains special solidifying chemicals that make the soap a solid bar of soap. Where as shower gel doesn't need this solidifying element because it doesn't need to become hard. This solidifying chemical reacts with the skin in a way that makes it feel squeaky clean.
