5. Scrubbing too hard.

Sure, exfoliating is all well and good, but you only need to do it about once a week. Once again, scrubbing doesn't do your skin's defenses any favors, so be gentle.

7. Not washing your feet.

Yes, all the soap from the rest of your body makes its way down, but your feet need more of a personal touch. If you don't get in there and scrub between your toes, you're tempting athlete's foot and other bacteria and fungus to set up shop and grow.

Razor blades aren't cheap, so it's understandable to want to stretch it out, but dull razors cause nicks and host bacteria — a recipe for an infection if there ever was one.
