How Do Secret Antiperspirants Help Prevent Underarm Odor and Wetness
Because perspiration in the underarms doesn't readily evaporate, a feeling of wetness results, and bacteria thrive in that wetness, creating underarm odor. Secret works by slowing the flow of perspiration to the surface of the skin. It does so by being pH (measure of alkalinity) balanced. When the active ingredient in Secret comes in contact with your perspiration, it dissolves into the sweat ducts. As you continue to perspire, the perspiration makes the pH of the solution rise. When the solution reaches a high enough pH, the active ingredient forms superficial plugs in those sweat ducts, reducing the flow of perspiration to keep you feeling dry. Secret protects you from underarm wetness (antiperspirant) and also helps prevent underarm odor (deodorant).
Do Secret Antiperspirants Have an Expiration Date
Yes, Secret antiperspirants have an expiration date located either on the bottom of the container or on the bottom of the back label. Our research shows the ingredients are stable until the expiration date if stored according to instructions on the label. Beyond that date, the ingredients may no longer be stable and/or the product formulation may change.
How Do Deodorants Work
Unlike antiperspirants, deodorants don't reduce wetness; they help reduce the bacteria that thrive in perspiration and cause the odor. By doing this, deodorants cover up underarm odor. In addition, most deodorants are scented to also fight odor.
