Chemistry of Skin Cleansing Cloths and Pillows
Soap and water are basic elements of cleansing. Soaps are emulsifiers, which means they remove dirt and germs by making them water-soluble. Typically, oils won't rinse away in water, but soap attaches to dirt and oil particles so they can be removed with water [source: PG Beauty Science]. But the problem with many soaps is that they can deplete your skin's essential oils, which can cause dry, flaky skin.
Cleansing cloths and pillows work on a similar principle to soap without causing excessive drying. They contain moisturizers and mild soaps that are specifically designed to clean the skin and remove excess oil without overdrying [source: Mayo Clinic].
