If you use antiperspirant deodorant, applying it is most likely part of your morning routine. It’s much more effective, however, to apply it at night before bed.
Applying your antiperspirant in the morning, particularly right after showering, makes it harder for the active ingredients to get down into your sweat ducts and clog them. In the morning your sweat volume is typically higher than it is at night, and your antiperspirant will wash right off.
The night is the best time for application because your sweat glands are less active and your skin is drier. The effect of the ingredients usually lasts around 24 hours and will remain active when you shower in the morning because the pores will still remain plugged. So, if you haven’t already, switch up your daily routine and add antiperspirant to the night shift. If you’re not sure of what kind of deodorant to buy, take a look here.
