FAQs of sweat protection
  • A true antiperspirant – like Certain Dri – should inhibit the flow of perspiration. The more effective the formulation, the more effective and longer-lasting the antiperspirant relief will be. Generally, an antiperspirant is also a deodorant because it prevents perspiration which retards bacteria and odor formation. However, a deodorant is not an antiperspirant.

  • Deodorants differ from antiperspirants in that they do not control the flow of sweat. Both antiperspirants and deodorants often contain fragrances to help mask the smell of body odor. Rarely, however, does a deodorant retard bacterial growth and odor for more than a very brief time.

  • Any of the following factors, separately or combined, can cause varying amounts of perspiration: physical exertion; mental or emotional stress; warm or hot temperatures; non porous, heavy clothing; obesity or endocrine dysfunction; inherited factors etc. When your body “overheats” as a result of these factors, it activates the sweat glands, especially those in the underarm area, to produce perspiration which is emitted through your skins’ pores.” The perspiration then evaporates to produce a cooling effect, thereby reducing the body’s skin temperature.

  • In its freshly released state, perspiration is generally odorless. However, when it exists in a confined and damp underarm area, it provides an environment that combines with bacteria on the skin, which can then cause odor. Specifically, sweat from the apocrine glands, located in the underarms, contains fatty substances and proteins that interact with bacteria living on the skin to create body odor.
