Certain Dri Prescription Strength Clinical Roll-On

Most effective antiperspirant you can buy without a prescription

Certain Dri Prescription Strength Roll-On is prescription strength, with 12% Aluminum Chloride, and the most effective antiperspirant you can buy without a prescription. Other antiperspirants may have aluminum complexes at higher percentages – but they are not the same. 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** and is why Certain Dri Prescription Strength Roll-On is different from the rest.
**Based on a 2017 independent study, Aluminum Chloride is #1 doctor recommended ingredient for excessive sweating.

Directions

Best Practice Is Before Bed Antiperspirants work best while you sleep to stop perspiration the next day. This is when you sweat less, allowing the active ingredient to better get into pores. Don’t worry, it will not wash off after bathing in the morning.
Be Certain Your Armpit Area Is Dry To reduce the risk of irritation, underarms must be completely dry prior to application. Do not use immediately after showering; or if skin is broken or irritated. Consider using a hair dryer on the cool setting to help dry your underarms before application.
Apply Certain Dri sparingly Only a few downward strokes under each arm are needed. Tilt bottle and roll on to cover entire underarm area. Do not use directly after shaving as this may cause irritation.
Pair It and Wear It For added deodorant protection, Certain Dri Everyday Strength Clinical Antiperspirant + Deodorant can be applied in the morning for an extra layer of freshness and protection.

Have sensitive skin? Do a patch test.

Patch testing is a method of testing a new skin care product or a new skin care ingredient to see if it will work on your unique skin. If you have sensitive or allergic skin, it’s always recommended to do a patch test or consult your physician. Consider trying Certain Dri Extra Strength instead if you have sensitive skin as it contains a strong active ingredient that may be gentler on skin.

More about Aluminum Chloride

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 brand.

Aluminum Chloride – smallest molecule support

AlCl₃ is a simple inorganic salt compound, while aluminum chlorohydrate and other antiperspirant actives are best described as inorganic polymers that form relatively large poly-aluminum complexes based on repeating Al-13 units.
Size exclusion chromatography, such as HPLC, separates and characterizes materials on the basis of molecular size. With this techniques, the larger molecules pass through the column faster, while the smaller molecules come out slower. Tests clearly illustrate that AlCl₃ is smaller.
By using the molecular formula for AlCl3, and the empirical formulas for ACH of Al₂(OH)₅Cl and a typical AZG-tetra salt of ZrAl₂Cl₃.₃₁(OH)₆.₆₉, the molecular weights can be computed as 133.34, 174.45, and 370.59 gm/mole respectively.
Aluminum chloride is the smallest molecule based on basic chemistry considerations, being applied to antiperspirant actives.
