Is it normal to sweat through deodorant?
Mostly.Normal for most people
Yes, it’s normal to sweat through deodorant—deodorant helps with odor but doesn’t stop sweat. An antiperspirant is the product designed to reduce sweating, though it may not stop it completely.
Deodorant mainly helps control odor; it doesn’t keep your armpits dry. Even antiperspirant can lose the battle during exercise, hot weather, stress, or just a sweaty day. You’re far from the only person whose shirt ends up telling the story.
If you want less sweat, look for a product labeled antiperspirant and apply it to completely dry skin. If the sweating is suddenly much heavier than usual or regularly disrupts your day, it’s worth asking a healthcare professional about it.
