Raise your hand if this ritual sounds familiar: You have a job interview, so you arrive fifteen minutes early, looking your best, and sit in the waiting room with your right hand palm-up on your knee, airing out for the inevitable handshake. You’re afraid of sweaty palms. And while you could carry a paper towel with you, or even swipe on antiperspirant, there’s another fix out there—one you might not guess.Botox, the same injectable used to fight facial wrinkles, can turn off the waterworks.

“Botox also works for excessive sweating,” says Marina Peredo, a board-certified dermatologist and founder of NYC’s Skinfluence. “And some people will treat their hands. Either both hands, or just their right hand, because when they shake they don’t want their hand to be sweaty.”
