Underarms: Nothing tops a shaving-foam-and-razor combo (look for aloe or shea-butter moisture strips) for navigating this ultrasensitive, uneven terrain in a pinch, but for smoothness that lasts for weeks, try preloaded wax strips, which rip away coarse armpit hair in one fell swoop. (Beware the afterburn if you dare to wear deodorant without waiting a day or two post-yank.) Got fair skin and dark hair? Repeated five-minute treatments with a gentle at-home laser can beat regrowth for good—at a fraction of doctor's-office prices.
