Heavy Duty Beauty Goods for Hot Weather
Before going to bed, apply a potent sweat-stopper, like Dove Clinical Protection Antiperspirant Cool Essentials―the scent smells clean, and not overly powdery. While you sleep, its prescription-strength formula seeps into sweat glands to better prevent perspiration the next day―even after you shower it off in the morning. Bonus: Slick it over the soles of your feet to avoid blisters.
To buy: $8, at drugstores.
