Antiperspirants temporarily plug the sweat ducts with aluminum compounds in order to reduce perspiration. Deodorants contain bacteria-fighting ingredients to reduce odor, but do little to prevent sweating. Several mass-market products work as both antiperspirants and deodorants. All natural products, on the other hand, do not have antiperspirant ingredients.

Reviewers say the following about deodorants and antiperspirants:

  • If you want to reduce perspiration, look for an antiperspirant. Antiperspirants block the sweat ducts, reducing perspiration and the odor that often goes with it. Many also contain deodorizing ingredients to further prevent odor.
  • Apply antiperspirants at night for the best results. Experts say this is true even if you shower in the morning. Most people sweat less at night, giving the antiperspirant more time to create an effective plug. Standard antiperspirants can be applied again in the morning for extra protection, but prescription-strength formulas may be a bit too strong for reapplication.
  • There isn't much difference between men's and women's deodorant. A quick look at the ingredient list of products marketed to men and women confirms that they are basically the same. The main differences lie in fragrance, packaging and marketing.
  • Don't apply deodorant right after shaving. Skin is more sensitive right after shaving, and both deodorants and antiperspirants can cause irritation.
  • Look for fragrance-free products if you have sensitive skin.
  • Allow antiperspirants to dry completely before dressing. Yellow stains on clothes are caused by a reaction between antiperspirant ingredients and proteins on the skin. Allowing products to dry completely will minimize staining as well as white marks left behind on clothes. You can speed up the process by using a hair dryer.
  • All-natural products cannot prevent perspiration. Natural ingredients do not block sweat ducts and therefore only provide deodorizing benefits.
