There is nothing more uncomfortable or offending than sweaty feet in the summer heat. Those with excess perspiration, called hyperhidrosis, can find wearing closed shoes uncomfortable and sandals downright slippery.
Botox is known to be FDA-approved for its ability to shut off excess perspiration in the underarm region, but a common off-label use includes help for sweaty feet, palms and even the scalp. The multiple quick injections to a specific region can be uncomfortable, so be sure to ask your doctor for a topical numbing cream first.
