Is it normal to use deodorant before bed?
Yep.Totally normal
Yes, it’s normal to put on deodorant before bed. If you use antiperspirant, bedtime can be a particularly effective time to apply it.
Plenty of people put deodorant on at night, whether it’s part of their routine or they just want to feel fresh in bed. There’s no rule that says it has to go on in the morning.
If your product is an antiperspirant, applying it to dry skin before bed can help it work while you’re less sweaty. Deodorant mainly helps with odor, so you can use it whenever you like. If it irritates your skin, try a different product or give your underarms a break.
