Secret Invisible Solid Antiperspirant and Deodorant - Powder Fresh, 5 pk.

Q. What is antiperspirant and how does it work?

Antiperspirants act by plugging the sweat ducts, reducing sweat. Because perspiration stimulates odor-causing bacteria, antiperspirants also help reduce body odor.

Q. How do Secret antiperspirants help prevent underarm odor and sweat?

Because perspiration in the underarms doesn't readily evaporate, a feeling of sweat results. Bacteria thrive in that sweat, 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 sweat (antiperspirant) and also helps prevent underarm odor (deodorant).

Q. How do deodorants work?

Unlike antiperspirants, deodorants don’t reduce sweat; 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 fight odor.

Q. 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.

Q. What causes underarm sweat and odor?

Perspiration is the body's natural way to regulate its temperature and hydrate the skin. Perspiration itself is essentially odorless and evaporates readily. In areas like underarms, where perspiration can't readily evaporate, it causes the feeling of sweat. Bacteria, which thrive in warm and moist surroundings, break down the perspiration and create underarm odor.
