If you sweat heavily, a regular drugstore stick applied in the morning is set up to fail. The best antiperspirants are stronger, used differently, and matched to where you sweat.
Antiperspirant vs. Deodorant
Deodorant tackles smell. Antiperspirant reduces sweat using aluminium salts to plug ducts. For heavy sweating you need an antiperspirant.
What to Look For
- Clinical or maximum strength — a higher concentration of active.
- Aluminium chloride hexahydrate — the strongest OTC active, the go-to for serious sweating.
- Format for the area — roll-ons and solids for underarms; dedicated antiperspirants for hands and feet.
The Application Trick That Changes Everything
Apply it at night, to completely dry skin, not in the morning. Overnight, the active settles into and plugs the ducts.
When OTC Isn’t Enough
Move up the ladder — prescription-strength formulas, iontophoresis for hands/feet, or Botox for underarms.
The Bottom Line
For heavy sweating, choose a clinical-strength antiperspirant, apply it at night to dry skin, and back it up with shields or undershirts.
