Is it normal to sweat through antiperspirant?
Depends.It depends
Yes, it can happen: antiperspirant reduces sweating but doesn’t always stop it completely. Applying it to completely dry skin at night may work better than putting it on just before you head out.
Antiperspirant can’t always keep up with heavy sweating, stress, heat, exercise, or your body’s own sweat levels. And if the product is actually deodorant, it helps with odor but won’t reduce sweat.
For best results, apply antiperspirant to dry skin before bed; many formulas work better when they have time to settle in. If you’re still regularly soaking through clothes despite using it as directed—or the sweating is suddenly much heavier than usual—it’s worth checking in with a healthcare professional.
