Products labeled “clinical strength” contain various aluminum active ingredients at various percentages which can be confusing… as all active ingredients are not the same, and a higher percentage does not necessarily equal a more effective solution. Which aluminum complex is better? What percentage is right? The answer and how each will work for you depends on how much sweat control you need.
Certain Dri Prescription Strength Clinical - Roll-On: This antiperspirant is the strongest in the Certain Dri line with 12% Aluminum Chloride, and is the most effective antiperspirant you can buy without a prescription. Aluminum Chloride is the strongest and most effective active ingredient available in antiperspirants and is the same active ingredient in many prescription formulations. Aluminum Chloride is the #1 doctor recommended active ingredient for excessive sweating**. Because of the strength of this active ingredient, it is only available in roll-on form.Learn More

Certain Dri Prescription Strength Clinical Roll-On is unique in that it contains the strongest, most effective active ingredient – aluminum chloride, the #1 doctor recommended ingredient. This is also the active ingredient that is found in many prescription antiperspirants. This Certain Dri formulation is water-based instead of alcohol-based, so it’s gentler on your skin than prescription antiperspirants.
Aluminum chloride works differently than other aluminum compounds. It penetrates to a deeper level of the sweat gland to stop sweat where it starts. Aluminum chloride molecules are smaller and fill the sweat duct more effectively than larger aluminum compounds. This means that the active ingredient in Certain Dri Prescription Strength Clinical Roll-On will help prevent perspiration more effectively, and won’t wash off in the shower.
The pink circles above represent the molecules in other clinical antiperspirants as they enter a sweat gland in your underarm.
Most clinical OTC (over-the-counter) antiperspirant brands use Aluminum Zirconium Complex (15-20%) as their active ingredient. This antiperspirant ingredient contains larger molecules that sweat “grabs” and pulls them into the sweat duct to form a plug.
Certain Dri® Prescription Strength Clinical Roll-On, represented by the green circles, stops sweat on a deeper level by using Aluminum Chloride, an ingredient with smaller molecules, which is more effective in getting into the pore and reducing sweat on a deeper level.
If you’re looking for real “clinical strength” antiperspirant options that can help you with excessive underarm sweating, try Certain Dri®, the #1 doctor recommended
