We aren’t saying it is a big mistake; rather it is that your deodorant isn’t as effective as it could be. Using deodorant isn’t a difficult thing; you apply the stuff to your armpits. Done. For this, it doesn’t necessarily matter whether you are using a roller or a spray. You only need to ensure that the liquid ends under your armpits so it can do its thing. But can we say it is actually simple as that? According to an expert, we are probably all using deodorant in a wrong way all this while.
It is not really incorrect, actually but the deodorant is less effective than it could be.
Deodorant makes sure you sweat less and, if you do sweat, it masks any sweaty odour that you might be emitting. Yet, there is a specific way of applying the antiperspirant if you want to get the most out of it and make sure it is as effective as possible. And that is by applying it at a particular time of the day.
Surprisingly, you shouldn’t apply the deodorant after you have woken up, but instead before you go to sleep. A professor of dermatology explains to Allure that it is best to apply deodorant on dry skin right before you go to bed. David Bank from Columbia University Medical Center agrees with this notion. He further explains that the antiperspirant will work better this way. It is definitely because the aluminum salts in the antiperspirant get the time to plug the sweat glands during the night, which implies that you will sweat less.
