Stay dry with Certain Dri
May 21st, 2008Say goodbye to excessive underarm perspiration with Certain Dri Anti-Perspirant. It’s an underarm formula that is applied at night and is supposed to last for 72 hours. I haven’t tested its ability to work this long (I’m paranoid about underarm odor), but I’ve been using it for the past week and it works brilliantly over a single day. No armpit perspiration and no need for deodorant. The effectiveness of the product blows me away.
I don’t know whether it is harmful to stop underarm perspiration completely. But you might like to use Certain Dri on days when you’re wearing a top or dress that is prone to showing underarm perspiration, or on days when you expect to get a little more anxious but would like to look cool, calm and collected.
It really works Betsy. Thank you for the recommendation!
Don’t let perspiration puddles put a damper on your day. Get Certain Dri for $5.95 at any drug store

I’ve used Certain Dri in the past, and it’s super effective. However, it takes a few days to build up, so you can’t pick and choose when to use it. It’s something you really have to commit to. On the plus side, once I’d been using it for awhile, I start ed skipping days without increased perspiration.

This product made my pits so itchy I wanted to claw them off my body. But. Although they were itchy, they were very dry.

Interesting. I haven’t had the itchy armpit thing (yet), and this product offered over night effects. Perhaps it has something to do with skin type and the weather?

I’ve heard a lot of great things about this product. I do want to say that most deos and antiperspirants can cause armpit stains - ick! Not only are armpit stains (darkening of the skin) stubborn, they take forever to go away, and are extremely unsightly. There are a number of products like DermaDoctor (Sephora) that is an antipersipirant/deodorant/skin brightener. Then there are other products, such as the one made by Nivea, that doesn’t cause staining/darkening of the skin. FYI.

I just have re-adjusted the type of clothing I wear in the summer & stick to airy things. But then I have lots of sensitivities & if it made one person itch - it would me, too!

It’s probably just me and my weird body chemistry. Many antiperspirants don’t work at all for me…they make my pits smell metallic and I still drip sweat. Certain-dri really did keep me dry! And odor-free. I was just itchy.

I’ll definitely have to give this a try. Did any of you have problems with it staining any of your clothing or anything?
May 21st, 2008 at 5:21 pm
To Angie and K,
I am excited to know that there is something that could stop armpit perspiration! Since the wedding season is coming up, I should give a shot on this item.
Even though the no stain on the armpit is wonderful, I have to agree with your consern about no sweating, Angie. If you are planning to be in place that is extreamely hot (ex. India, beach etc) no sweating could lead to your body unable to control your body temperature (which is not a good thing).
So I would like to ask K, do you remeber how long it took for you to get armpit perspiration back after you stop using it? A day? A week? Since it might help us plan when to use and when to stop…

This product actually prevents clothing stains, Ana. It’s especially good for white shirts that go yellow because of deodorant and perspiration.
May 21st, 2008 at 9:48 pm
That’s great, I’ll definitely have to give it a try then!

How do you deal with showering? Does it stay on if you shower in the morning?

re: anti-persperant being harmful
There has been some indication that the aluminum in anti-perspirant can be harmful. Its related to such things as Alzhiemers disease but the jury is still out so I wouldn’t stress too much about it. Personally, I still use anti-perspirant but lean towards those with small % of aluminum and only use them in the warmer months. Besides the aluminum, I wouldn’t worry about wearing it for all day coverage since your body sweats from other locations so blocking that one wouldn’t make you sick or have any ill effects.

I want to edit my last post to say that the official POV now is that anti-perspirant was not linked to Alzhiemers in the latest studies - its hard to keep up these days with what is good and bad for you! Based on that, I wouldnt worry about causing any ill effects.

This might be something you would want to use for an occasion you definitely don’t want wetness to show. But be careful—My Doctor said that using antipersperants on a regular basis–especially one so effective can actually lead to lumps in the breast area or under the arms. Just passing on what he told me. To stop the body from releasing the toxic properties of our body completely has to be bad for you.

I love this product and use it often. It’s the only thing I’ve found that allows me to wear shirts in fun colors… I used to stick to black only because I would sweat so badly!
That being said, as the above posters have mentioned, it DOES itch like the devil. Also, you should definitely only use it at night… and make sure to wear old clothes or something you don’t care about because it bleaches the armpit area! I forgot to apply it one night and put in on in the morning instead and ended up ruining a shirt! Don’t make this mistake!

After reading some comments,
I felt that I need to do more research about the body temperature regulation since it was something I was told from dermetologist a while ago. After doing some research I found a paper published at International Journal of Cosmetic Science on 2003 that talks about that exact question. (title is “The Effect of Antiperspirants on Whole Body Sweat Rate and Thermoregulation”)
From experiment they did, they concluded “although antiperspirant prevents sweat production in the axillary area, this does not impact on the ability of the
body to thermoregulate following a rise in core body temperature.”
I also found some interesting fact that I thought you guys might be interested.
1. We swat 1L of sweat/day from 3 million sweat glands
2. This could increase to 2L-10L if you excersized or in a hot weather.
3. The sweat from arm is somewhere between 1-10ml from 25 thousand sweat glands.
So I guess the amount of sweat from arm is less than 1% of total sweat but it causes so much stress!!

As someone who suffers from excessive underarm sweating, this product has been a godsend! I’ve used it religiously for the last 2 yrs and could not live without it. No more embarrassing armpit wetness on my shirts! I’ve learned through trial and error that it has to be applied right before bedtime, on clean DRY underarms… You need to make sure they are dry before applying, and never apply right after a shower, or it will itch. It does take time to build up for max effect, so you do have to commit to daily use. If you shower in the morning, that’s ok, it will not come off as it gets absorbed into the topical sweat glands in your skin. I sometimes layer it with Certain Dri AM in the morning, which has a light, fresh scent. Also, it doesn’t completely stop your body from sweating, just keeps it under control. You will still sweat elsewhere as you might normally if your body needs to release moisture. I’ve been to several dermatologist and they all recommend using it daily only if you have perspiration issues, or just as prep for special occasions.

Ouch.
I’d rather sweat, thanks.
Because it’s crazy hot and humid here, everybody sweats. I’d rather be concerned with smells that aren’t my perfume. For that, I use Thai crystals: http://www.deodorantstones.com/item7131.ctlg Works better than any of those awful sealants preferred here (and, apparently, “here” at this site).

I love love LOVE Certain Dri. I found it a couple of years ago and tried it out of desperation. I would sweat all the time, summer or winter and always wore dark colors to hide the stains. I turned my roommate, both my sisters and my mom on to this. This product ROCKS!
May 30th, 2008 at 7:06 am
Question: I love Certain Dri too. But I have notice that it stains my armpits with a light brown color (looks like I didn’t shave). It works great so I hate too stop using it but, it’s summer season and I do not want to wear tank tops because of it.
Does anyone else have this problem?
THANKS!
May 30th, 2008 at 11:58 am
You apply it at night Christie, and it’s absorbed after 5 minutes which makes showering in the morning fine. Hope that you like this product as much as I do.
Thanks for the additional information ladies. It’s food for thought.

I starting using this product on Angie’s recommendation, and it’s fantastic! I have eczema, and this product didn’t bother me at all–no itchiness, darkening, etc. I do follow the directions religiously though, and it doesn’t completely cut out the sweat if I’m doing serious walking in the sun or anything, but it definitely cuts down on it. I love it and have thrown my old deodorant away.
September 14th, 2008 at 7:52 pm
so .. i got this product tonight, and just put it on for the first time because im going to bed soon.
it ALREADY itches like crazy! - is this normal?
i hope this product works!!

I’ve been using this for a while, and it is by far the best on the market. I used to sweat real bad from my pits after the mitchum smart solid gave me this hideous scabby rash in my under arm. All those new products like old spice high endurance and the other ones that say they stop arm pit sweating just made my pits leak like a faucet. So I tried certain dri and it has completely stop the sweating. The only drawback is it makes me itch like a mofo after I put it on, but I usually put some eurucin anti itch cream on after certain dri soaks in so I can sleep at night and not try to scratch my arm pits off. The itching doesn’t bother me during the day so its all good. I still put on a regular deodorant in the morning just because it feels better to have to have it on during the day. I would give this a 9 out of 10 only because of the itching, but this is something you have to try if nothing else works.
