Six Things You Don't Know About Armpit Care (And Should!)

Choose a deodorant with moisturizing benefits. "When you shave, 36 percent of what you take off is actually your skin," says Dr. Marmur. "If you strip away the top part of the skin, you evaporate your natural oils which can cause a rash."

Aluminum is a necessary and unharmful ingredient in antiperspirants. "No studies show that aluminum causes any problems," says Dr. Marmur. "As a physician, I often prescribe aluminum antiperspirants for people who suffer from hyperhidrosis that are many times more potent than products you find in the drugstore."

When applying deodorant (three swipes is sufficient), be sure to go beyond the deep part of the underarm. Sweat glands extend two inches around the area.

If you find that three swipes of deodorant isn't enough to get you through the day, see your dermatologist about clinical strength options.
