Your beauty and skin-care routine is made for little hacks. Like letting conditioner sit in your hair while you shower for enhanced silkiness and softness. Or slathering on body lotion right after the shower, when skin is still damp, to lock in hydration.

But there's one thing you might want to rethink in your post-shower routine: applying antiperspirant right after you towel off in the morning and head out to meet all the sweat-inducing stressors of the day.
"Antiperspirants work best when applied to clean, dry skin," S. Tyler Hollmig, MD, director of dermatologic surgery and director of laser and cosmetic dermatology at The University of Texas at Austin, tells LIVESTRONG.com.
Makes sense. Here's the kicker, though: "Since we typically sweat less at night, applying in the evening often helps improve efficacy," he says.
That's right: You may want to switch your shower-and-swipe routine to nighttime, before bed.
"Antiperspirants are like a bathtub stopper. They work great when in position, but otherwise are worthless and just get sloshed around the tub."
Why Antiperspirants Are at Their Best Before Bed
Dr. Hollmig explains that most antiperspirants are aluminum-based.
"The aluminum blocks sweat ducts in order to reduce the amount of sweat reaching the skin's surface," he says.
When you swipe this onto clean, dry skin, the aluminum salts mingle with sweat to plug sweat glands.
However, if you apply an antiperspirant right out of the shower — when you're still damp or a bit hot and sweaty from the water — the aluminum salts will mix with sweat before getting into the skin. That means the plug is created above the surface of the skin rather than getting into the sweat glands. And they'll just wash right off, Dr. Hollmig says.
"Antiperspirants are like a bathtub stopper. They work great when in position, but otherwise are worthless and just get sloshed around the tub," he says.
What About Deodorant?
Deodorants are different from antiperspirants.
"Deodorants actually do not help reduce sweat. Instead, they mask odor by neutralizing bacteria or by emitting a scent that hides body odor," Dr. Hollmig says.
Because there are so many products out there — antiperspirants, deodorants, combination, natural, etc — he recommends taking a moment to think about what you need (sweat- or odor-stopping, or both?) before you buy. If you're not sure, you can always ask your dermatologist.
What if I Shower in the Morning?
That may be fine! "This is one of those topics where each person has to choose their own adventure based on their propensity to sweat and goals for scent," Dr. Hollmig says.
If you shower in the morning, swipe on antiperspirant and feel fresh as a daisy and sweat-free all day, then you're fine. No need to feel pressure to change a routine that's obviously working for you.
Same with if you're someone who uses deodorant. No need to step up to an antiperspirant if your go-to odor-fighter is enough.
However, it may be worth switching up your product and/or routine if what you're doing now isn't cutting it. For instance, if you're using a deodorant right now but have breakthrough sweat that's pitting out your clothes, then consider moving to a stronger product like an antiperspirant.
Similarly, if you're a morning shower kind of person but notice that you have to constantly reapply antiperspirant throughout the day or it's not stopping sweat as well as it should, then try a shower at night, dry off thoroughly and completely and apply antiperspirant before bed, giving it enough time to plug your sweat.
You're feeling fresher already, aren't you?
