I got given one in July 2010, it was for a few seconds and I still have a pale mark where it happened, and got given one in December which was for much longer and I don't know if its going to heal properly. I would advise not to do it again.
IF you have a cut or a rash under your pits it can burn or sting
Ti last a year or two
Treating a burn due to deodorant is a fairly simple process. First, the person should thoroughly remove the deodorant using gentle soap and water. Then, the person should cover the burn in antibiotic ointment and cover with a bandage. Finally, after a few hours, the person should remove the bandage and let the burn breathe. It should heal within a few days.
Because you might be allergic to your deodorant
depend on treatment it can last up to one weak
Any kind of womens deodorant will work. It is less harsh. I didn't believe it when I first heard it but it really works.
Unopened deodorant can last for up to 3 years if stored in a cool, dry place. Once opened, deodorant can last between 6 months to 2 years, depending on the type and formula. It's important to check for any changes in texture or smell to determine if it's still safe to use.
Because you are most likely fat and ugly. Get a life and your under arm will be better.
Secret
It depends on the type of burn on this particular one I think maybe two weeks.
You can bring a deodorant can in your carry-on luggage as long as it is 3.4 ounces or less.
If you mean how long does a bottle last, then it depends. Most solids last about 3 weeks for a man. Some gels last only 1-2 weeks. But, if you like gel, Klima Deodorant sells a product which I use called Hyperdri that lasts 60 days per bottle. And, it works great at stopping sweat.
