Use Antiperspirant at Night, Not in the Morning

The Problem

You apply antiperspirant in the morning and still sweat through your shirt by noon.

The Hack

Apply antiperspirant at bedtime on dry skin. It takes 6-8 hours to form the aluminum plug in sweat ducts. Morning shower won't wash it off — it's already absorbed.

Why It Works

Antiperspirant needs time to create aluminum chloride plugs in sweat ducts. At night, you sweat less and skin is dry — optimal absorption conditions. By morning, the active ingredient is in the duct regardless of washing.

Pro Tips

• Apply to DRY skin — moisture prevents absorption
• Still use deodorant in the morning for scent if desired
• Clinical strength options work even better (Certain Dri, SweatBlock)
• This is the #1 recommendation dermatologists make for sweating
