The thing about routine is that we usually don’t stop and question it—even though sometimes, we should. Here’s one science-backed reason to re-evaluate your morning hygiene routine: It turns out you’re probably doing it wrong.
Or, at least, if you’re applying deodorant in the morning, you’re not using it to its maximum effect. It’s most likely your deodorant is designed for nighttime application. “Remarkably, this gives the best possible result, but almost no one does it,” Jeffrey Dover, M.D., a Boston-based dermatologist told Greatist.
Deodorants and antiperspirants are actually two separate products, although what you’re using is likely a combination of both. Deodorant is a short-term fragrance boost, which aims to mask body odor. Antiperspirants actually do the work: using aluminum compounds, the product targets your sweat ducts, plugging them to keep your skin dry. If aluminum is one of the active ingredients listed on your deodorant label, then your deodorant is really (at least partially) an antiperspirant.
Stick with us, here. So if antiperspirants work by plugging your sweat ducts, it’s better to apply at night when the body’s natural sweating rate is decreased. This helps prevent perspiration well before your sweat ducts kick into high gear, as opposed to trying in the morning, where the battle has already likely been lost.
If you need extra fortification against body odor, you can always apply again in the morning—there’s no harm in frequent application.
