Certain Dri Product Facts

The Certain Dri Protection System™ Antiperspirants are the choice for controlling wetness, since the most common active ingredients, aluminum compounds, block the pores to inhibit the release of sweat and help absorb odor-causing moisture. However, for people have been diagnosed with axillary hyperhidrosis (excessive sweating of the underarms) or who feel that they suffer from excessive perspiration on a regular basis or occasionally, due to stress, occupation, etc., there is:


Certain Dri Anti-Perspirant Roll-On:

  • This doctor-recommended, non-prescription product is applied several times a week at bedtime.
  • According to an independent survey, a majority of dermatologists prefer the Certain Dri® formula for treating hyperhidrosis or excessive perspiration, over the formulae in all the other anti-perspirants combined.
  • Certain Dri® is colorless, fragrance free and has been categorized as safe and effective in the ongoing review of non-prescription drugs by the U.S. Food and Drug Administration.
  • Because of its therapeutic ingredient, Certain Dri® is used differently from all other anti-perspirants.
  • It is applied sparingly at bedtime, and it will not wash off after bathing/showering.
  • In many cases, the user will discover that it will not be necessary to apply Certain Dri® every night to control the problem.

Certain Dri Anti-Perspirant is available with 12 percent aluminum chloride, the active ingredient used in prescription anti-perspirants. Because Certain Dri® is water-based (vs. alcohol-based like its prescription competitors), it is available without a doctor’s prescription.

If you prefer a solid application there is New! Certain Dri® Solid Anti-Perspirant

  • Created specifically to complete the line of Certain Dri antiperspirant products for those who want the same 72-hour protection from excessive underarm perspiration in a solid application.
  • The product is specially-formulated to provide everyday, all-day dryness for those who suffer from excessive underarm perspiration.
  • Certain Dri® Solid Anti-Perspirant contains 25% aluminum sesquichlorohydrate (Anhydrous). It is the only over-the-counter antiperspirant with this ingredient, which is more effective than the aluminum zirconium formula found in over-the-counter solid antiperspirants that are labeled “clinical strength.”


    For added odor protection look for new Certain Dri A.M.™ Underarm Refresher.
  • New Certain Dri A.M. Underarm Refresher was created for Certain Dri Anti-Perspirant users as a daily supplemental product for added protection against odor.
  • Used with original unscented Certain Dri, which is an antiperspirant (stops wetness), the two products make up the "Certain Dri Protection SystemTM.
  • Certain Dri A.M. Underarm Refresher is specially-formulated to provide every day, all day freshness for those who suffer from excessive underarm perspiration.
