When your antiperspirant fails you (or the day turns way more muggy than you had anticipated), run a DermaDoctor Med e Tate wipe across your underarms. The single-serve packets contain aluminum zirconium tetrachlorohydrex glycine, a superstrong―but safe―sweat inhibitor. You can even use them on the bottoms of your feet.
To buy: $48 for 30, dermadoctor.com.
