For Hyperhidrosis "This is the best product I’ve ever used! So glad I found this roaming around Walmart in 9th grade. Before, I had to wear black shirts or sweatshirts to hide my huge sweat stains under my armpits; even so, I would still get noticeable stains. Other types of deodorant seemed to have no effect. It was so embarrassing and ruined my confidence. I was so desperate to hide my sweat stains that I thought about using pads on my clothes or duct taping my armpits. It took a few weeks to kick in. I have used it every night for a few years now, and I use normal deodorant every morning. I no longer have sweat stains, even when wearing skin-tight or gray clothes! So happy that my armpit stains are now a problem of the past! However, it does cause itching, and my armpits developed swollen lymph nodes and rashes a few times. That’s why I only use it at night and don’t shave my armpits often. But overall, the mild itchiness is well worth being able to wear whatever I want to!!!!"

For Hyperhidrosis "I’ve been using Certain Dry for over ten years. I use it a few times a week, but not every day. When I first started using it, I used it daily, which caused a rash, so I cut down to every other day, and I can say I do not sweat under my arms anymore. It’s been ten years free of smelly, sweaty underarms. I tell everyone about this product. It does itch a few minutes after application, but it’s because it’s literally closing your pores. If you can deal with a little itch under your arms for a few minutes, it’s definitely worth the discomfort. This product changed my life. It changed my confidence. I love Certain Dri."

For Hyperhidrosis "I used Certain Dri and it was wonderful! I had finally found something that actually worked, even if I wore a sleeveless tank or shirt in the summer. Although I also got the very itchy, burning rash. Terrible rash, and it worked so well I continued to use it. The rash got so bad after a while, I began to notice that it had taken the color and pigmentation from my underarm in the entire area that I applied it. It is now two years later after discontinuing use, and I still have no pigment under my arms in that area. It looks like I was burned and have huge scars under my arms with no color. I am very tan as I have American Indian in my family background, and it looks horrible. I am embarrassed to wear a bathing suit now or sleeveless shirts at all! I am afraid, being it is now two years later and is still the same, it is permanent. :( I have gone back to Mitchum unscented roll-on as I cannot stand the powder smell. It works well but not as good."

For Hyperhidrosis "This product, when used correctly, did not work for me. It plugged my underarms, yes, but then caused me to sweat everywhere else-which, I'm assuming, because my skin wasn't used to sweating, caused me to develop blister-bumps on much of my skin. When (after a week) I realized it was likely this product and stopped, the rash slowly but surely went away. I had tried this years ago, and I guess the ingredients will never change or be less severe."

For Hyperhidrosis "I'm a female in my 20s and since I can remember, I have always struggled with excess, embarrassing sweating. This is the only product that has seemed to prevent my armpit stains entirely. But this product comes with a price. I do have sensitive skin, so I get a very abnormal severe rash when using Certain Dri. My armpits get a harsh red rash, and I have a hard time sleeping with it on because it says to apply at night. However, this rash is painful and itchy, so it is hard to relax and fall asleep, but in trade, you really will NOT sweat at all. I can finally wear white T-shirts without worrying about pit stains. I highly recommend NOT shaving your armpits before using at least 1-2 days because it makes them way more irritated and the rash can be worse. Also, the rash was noticeable to my friends because I was in a swimsuit, and they could notice it was bright red. Pick your battles between having an itchy, painful rash while sleeping or not sweating for 3-4 days. I only apply 2x a week between shaving my armpits."
