While not necessarily glamorous or decked out in fancy packaging, Certain Dri is a super popular clinical strength deodorant because it works, especially for people dealing with hyperhidrosis. Given the high percentage of aluminum chloride, those with sensitive skin might want to steer clear. But if you’re looking for a majorly heavy-duty deodorant, this is it. Reviewers note that you don’t even need to use it every day — many alternate with gentler formulas and still get fantastic long-term results. They also mentioned that it could cause a burning sensation upon initial application, but you can avoid that by making sure your pits are fully dried before applying.
Promising reviews: “I have constantly sweaty underarms and have tried bunch of different products. This is the most budget friendly option I’ve tried and it actually works! I am noticeably less sweaty, even after an intense workout or mowing on a hot day. I also love that it doesn’t leave any stains or residue on clothing, unlike some other products I have tried. I apply it about every other night, so long as I haven’t shaved that day, and have had almost no issues with irritation. On the “off” nights, I use a traditional gel deodorant.” — Amazon customer
“I am glad I tried this!
I tried all the drug store options and NOTHING was working. I was sweating through shirts even when I did not think it was hot enough to! Anway, I put this on after the shower maybe every 3rd night. It takes a bit of 5 min to fully dry. Then boom! results are great. My skin has had no reactions that is visibly noticeable. Only con – I did find it to slightly burn if I put it on after I shave. So, I try to not do that, but honestly it hurts less than razor burn.” — alyssa
“i’ve been using this for over a decade for a reason. i’ve tried all sorts of other products and none of them hold a candle to certain-dri. note: a little goes a long way. you don’t need to saturate your underarms (and honestly you don’t want to because this stuff is STRONG). too much and you’ll be itching all night. which brings me to another point: ONLY use at night before bed and NOT immediately after a shower/bath. i like to take a bath every night, but wait at least an hour before applying this product. if your pits are even a little humid before applying, you’ll itch like crazy. all that said, if you follow the instructions you only need to apply every 2-3 days and you’ll have zero sweat. none. at all. it’s a miracle! i’m naturally VERY sweaty especially in summer but with certain-dri i don’t have to worry about sweaty underarms.” — P&M
