Carpe Antiperspirant Lotion, like most treatments in the world, works best if used properly. But in our experience, simply stating the "proper use" is a poor way to help people make the best of Carpe. So in this article, we outline the most important points of the Carpe routine, and the science behind why they matter. And yes, we provide references to the scientific papers that we learned this from - so that you can learn more for yourself if you'd like!
Apply Carpe before bed
Many people think the best time to apply an antiperspirant is in the morning, but time  and again , research has shown that applying before bed leads to far better results. There are a few things that need to be known to understand why this is the case. First, Carpe, like all antiperspirants, isn't a simple 'sweat stopper' that prevents sweating for a few hours, but rather a treatment that works to reduce sweating until it dissolves out of the sweat glands . This dissolution of Carpe isn't caused by the simple passage of time, but rather by a certain amount of sweat attempting to escape to the skin and pushing away the Carpe - so if you're not sweating, the antiperspirant isn't losing efficacy. In fact, Carpe needs a bit of time without being attacked by sweat to do its best work and maximize efficacy . Fortunately, even if you have almost constant sweating (as is caused by primary focal hyperhidrosis, the common condition of excessive sweating), you likely don't sweat much at night. This is actually one of the main diagnostic criteria of primary hyperhidrosis - sweating a lot, but not sweating at night . So if you apply Carpe before bed, it'll have the full night to work on your sweat glands without getting attacked by sweat, leading to maximum efficacy in the day that follows. As put more scientifically by a research paper, "[the active ingredient] should remain on the skin for 6 to 8 hours to be effective. Overnight application best takes advantage of low sweat output during sleep because diffusion of the aluminum ions into the sweat gland may be negatively affected if the gland is actively excreting sweat... despite nighttime application, the product continues to work during the day" .
Apply Carpe to clean and dry skin
To work best, Carpe needs easy access to your sweat glands, and any dirt or grime on your skin may get in the way. Therefore, applying Carpe to freshly washed skin leads to maximum efficacy. When combined with the first rule of applying Carpe before bed, an evening shower may thus be the perfect precursor to applying Carpe. But drying the skin very thoroughly after washing is important, too - when exposed to water, antiperspirants like Carpe degenerate  and don't work as well as they could.
Use Carpe every day
Research on antiperspirants continues to show  that daily use is absolutely necessary for maximum effect - if you stop applying Carpe, your sweating will slowly return. But there's another, much less obvious benefit to continued use every day. Over time, with daily use, antiperspirants actually become more effective . You read that right. If you're using Carpe every day, it will work many times better four weeks after you start than on the day you start. In fact, a study on the active ingredient in Carpe showed that after two weeks of daily use, sweating was reduced by 48% - but after four weeks of daily use, sweating was reduced by 61%! 
And there's one tip we'd like to give you that doesn't need much scientific explanation - Carpe is very potent, so you don't need to apply a lot of it. The formula was designed to work and feel ideal when a pea-sized drop is applied to the palms, or a dime-sized drop is applied to the feet.
So that's the science behind how you can get the maximum efficacy from Carpe!
