Any craftsman will tell you: Choose the right tools for the job. Applied to showering, that means skin cleansers.
All cleansers do the same thing -- dissolve dirt and oil so you can wash them away. For best results, choose one that matches your skin type. If you have oily skin, try a cleanser that's also an exfoliant. An exfoliant is a product that removes dead skin, the perfect material for dirt and odor-causing bacteria. Mild exfoliants contain gentle scrubbers like citrus acid, and they're considered safe for regular use. Once or twice a week, wash your face with a specifically designed exfoliating product. If dry skin is a problem, consider using a liquid body wash instead of a bar.
Remember that hot water and vigorous toweling can irritate any skin. Use warm water and pat dry, rather than rub. You're removing water, not car wax.
Check your nails. With a nail brush, scrub out any crud the shower missed. Trim or file any rough edges with nail nippers -- straight across the top, slightly rounded at the corners. Occasionally, you might need something more abrasive, like a pumice-laced cleanser.
