Review Wednesday: Certain Dri

certain dri

My co-worker/friend who suggested Certain Dri to me also said she keeps it by the bed as it is to be applied at bedtime.

As embarrassing as it is to admit, I am an excessive underarm sweater/perspier.

I have tried a variety of deodorants and anti-perspirants and nothing has worked that well. And I have ruined a lot of shirts.

Recently a friend/co-worker told me about Certain Dri, an anti-perspirant, which claims to be clinical strength.

I decided to at least give it a try. And so far it seems to be working for me.

I have been using it for about a month and the underarm sweat has been drastically reduced.

I got the roll on at Target. It contains 12% aluminum chloride, which, according to the package insert, is prescribed to those with hyperhidrosis or excessive perspiration. Aluminum chloride works to shrink and close off underarm pores.

The package inset says when using Certain Dri nature simply and safely redistributes the perspiration to the rest of the body’s skin surface.

According to an article on Discovery Fit & Health, aluminum chloride in high concentrations may ultimately shrink the sweat gland, decreasing the amount of sweat it can produce.

The FDA requires that over-the-counter anti-perspirants contain no more than 15% to 25% of the active ingredient, depending on what it is. The FDA also requires that all anti-perspirants must decrease the average person’s sweat by at least 20%.

I checked my stick of Secret to see what the active ingredient is. It contains 19% of aluminum zirconium tricholorhydex glycine.

The pH balanced anti-perspirant/deodorant works better than the Degree I used to use. The Degree I used contains about 18% aluminum zirconium tetrachlorohydrex glycine. According to Wikipedia, aluminum zirconium tretrachlorohydrex glycine functions by diffusing into the sweat gland and forming a collodial “plug,” which limits the flow of sweat to the skin surface.

From the research I have done it seems that aluminum zirconium trichlorohydrex glycine is the same as aluminum zirconium tetrachlorohydrex glycine.

The aluminum chloride so far seems to be the best active ingredient for me.

Initially the Certain Dri is used every day and eventually it is to be used just a few times a week.

In my research I found that some believe aluminum chloride can cause certain health issues I am not going to go into those issues as I haven’t found anything scientific or concrete to prove any of them.

If you want to know more about the history of the anti-perspirant, this link gives a quick, easy and interesting read.

The roll on doesn’t travel well. The liquid spilled all over the place. Luckily I had put it in a plastic bag. I have only seen the roll on to buy in the stories. So I recently purchased the stick for p.m. and a.m. online. I haven’t received them yet.

Certain Dri works best when applied at night. I took the suggestion of my friend/co-worker and keep the roll on by the bed. Because nothing is worse than being all cozy in bed and half asleep when you realize you have to get up.

But I have to say I have noticed a drastic reduction in sweat since I started using Certain Dri about a month ago. I will continue to use this and looking forward to trying the solid version. Certain Dri gets 4 1/2 dumbbells.
