Schick Quattro, $9

With four blades, this Mercedes-Benz of shavers glides over all hairs in its path without nicks or razor burn, resulting in a very smooth shave. The rubber handle prevents slipups in the shower.

Tip: Always use a clean, sharp blade. “A dull or rusty one will abrade skin and leave razor burn,” says New York City dermatologist Laurie J. Polis. At the bikini line, an area notorious for developing shaving nicks and bumps, pull the skin taut and shave in the opposite direction of the hair growth.

To Buy: At drugstores.
