Sweat glands are present almost everywhere in the skin, except for the lips and a few other areas. Most of them give off the extremely dilute salt water known as sweat or perspiration. Their purpose is to cool the body by evaporation of water. Body odors are not produced by perspiration itself, but by the bacterial activity that takes place in the perspiration. The activity is most intense in warm, moist parts of the body from which the perspiration n cannot evaporate quickly, such as underarm areas.
Deodorants – the basic means of keeping this type of bacterial growth under control is through personal cleanliness of both the skin and clothing. Deodorant soaps containing antiseptic chemicals are now available. Though they do not kill bacteria, they do reduce the speed with which they multiply.
Underarm deodorants also help to eliminate the odor. They are not meant to stop the flow of perspiration, but rather to slow down the bacterial growth and mask body odors with their own scent. Such deodorants should be applied immediately after bathing. They are usually more effective if the underarm area is shaved, since the hair in this unexposed area collects perspiration and encourages bacterial growth.
Antiperspirants – Antiperspirants differ from deodorants in that they not only affect the rate of bacterial growth, but also reduce the amount of perspiration that reaches the skin surface. Since the action of the chemical salts they contain is cumulative, they seem to be more effective with repeated use. Antiperspirants come under the category of drugs, and their contents must be printed on the container. Deodorants are considered cosmetics, and may or may not name their contents on the package.
