For many, the instinct when washing up is to lather up with hot water to get rid of the day's deposits of dirt and oil. But hot water actually dries out the skin too much, washing away the oil necessary to keep skin supple and soft. While you don't want to cleanse with scalding water, wait for the tap to warm up to a nice, comfortable temperature -- cold water doesn't remove oil and dirt from the skin very well, paving the way for future breakouts.
Another skin care myth is that scrubbing is the best way to rid the skin of excess dirt. In fact, harsh scrubbing can have a very negative effect, stripping the skin of necessary oils and causing burns and rashes [source: WebMD]. Dermatologists also advise cleansing the facial area a maximum of two or three times per day. Overwashing causes the skin to become too dry, signaling the oil glands to produce even more oil to compensate. Instead, gently massage a mild cleanser, such as a foaming gel that contains salicylic acid, into the face for 30 seconds or so, then rinse with warm water [sources: Janes, Todorov].
