Even when the majority of the public is aware that the skin on the face is simply not the same as the rest of the body, there are still many people who use common soap and water to wash their faces. A proper cleanser is needed not just for the face, but for the entire body. Soaps literally strip the skin of essential oils, while run of the mill moisturizing cleanser bars leave behind a dull film. A cleanser should instead gently remove impurities from the skin, while leaving behind vital moisture. When purchasing a cleanser for the face or the body, a few simple tips can go a long way.

First, a cleanser should state on the label that it removes debris without over-drying the skin. Many skincare companies use harsh chemicals in an effort to get rid of grime; however, not only do these harsh chemicals seize the skin's natural moisture balance, but they can trigger the sebaceous glands to overproduce oil as well. An overproduction of oil can lead to pimples both on the face and body, as well as ingrown hairs and clogged pores.

Next, a cleanser should rinse off of the skin without leaving any trace behind. Some companies include ingredients in a cleanser that causes it to literally stick to the skin, making the face and the body appear dull and generally depositing an unpleasant residue. The entire purpose of the cleanser is to eliminate dirt and grime, and so it should not deposit anything except possibly vitamins, minerals, or treatment ingredients for a specific skin condition.

Last, a cleanser should always be oil-free. Not only can oil in a cleanser leave a greasy shine on the skin, it can easily clog the pores as well. A product that contains oil is more apt to cause blemishes and other skin irritations too.
