Try: Clinical-strength Antiperspirant

You've been showered and dressed for barely an hour and already your armpits feel clammy. Though some of us sweat more than others naturally, there are a few things you can do to perspire less profusely. First, lay off the coffee, cocktails and smokes. These vices can turn your glands into a faucet. Second, choose breathable fabrics like cotton to keep your body temperature down. If these tricks fail, upgrade to a clinical-strength deodorant, which contains more active ingredients (in most cases, some for of aluminum salt) to plug underarm pores, no prescription necessary. For protection that won't quit after a few hours, try a top-rated pick like Secret Clinical Strength Antiperspirant, $8.99, or Certain Dri Regular Roll-On, $8.49. Apply clinical-strength antiperspirant at night. While you're sleeping, you sweat just enough to pull the active ingredient into your glands and start the plugging process.

Try: Crystal Deodorant

Prepare yourself for one of the most annoying catch-22's of all time: Those yellow pit stains that ruin your summer whites aren't really caused by sweat. It's actually the combination of sweat and the aluminum in the antiperspirants we use. Your solution: Choose deodorant on days you'll be wearing white.

A crystal deodorant, like Crystal Essence Mineral Lavender & White Tea Deodorant Roll-On, $3.49, won't stop sweat the way antiperspirants do, but it will keep your armpits smelling fresh -- and your tops from turning yellow. After you wet the dry crystal and apply it under your arms, a thin layer of the crystal sticks to your skin, and its mineral salts help to reduce bacteria levels (the major culprit of B.O.). You may feel a little New Age-y rubbing a crystal under your arms, but your white shirts and dresses will thank you.

If you're sweating heavily, even when your body isn't overheating (e.g., you're camped out on the couch with the A/C blasting), you could be suffering from hyperhidrosis, a condition that causes people to sweat an abnormally large amount for no good reason -- usually in the underarms, hands or feet. Your first line of defense should be to talk to your doctor about your condition. He or she will likely recommend prescription antiperspirants like Xerac AC or Drysol. These are similar to over the counter antiperspirants but contain an extra kick of aluminum chloride to plug sweat glands and prevent sweat from reaching the skin. Many prescription antiperspirants can be used on the armpits, hands and feet, and can even reduce the size of sweat glands in the long run to keep excessive sweating in check. However, the higher amount of aluminum means there's a higher risk of skin irritation and staining. Consult with your doctor during pregnancy and before breast-feeding.

Try: Botox

Injecting Botox into your feet or armpits may sound like a red carpet extreme, but the method now has the FDA's stamp of approval for treating superfluous sweating.

According to Dr. Frank, Botox is a great option for the excessively sweaty who are also sensitive to fragrances in deodorants or the aluminum in antiperspirants. "This procedure has become one of the safest and most effective standards of care for excessive perspiration," he continues. How does it work? When injected, Botox blocks the signal pathways that stimulate sweat under your arms. The procedure is performed with topical anesthesia, is generally side-effect-free and lasts for four to six months. Each maintenance session will set you back $1,500.

Try: Deodorant Wipes

If you're on the go and constantly find yourself a bit too close to strangers (thank you, overbooked flight), and are convinced your usual stick is failing, give deodorant wipes a try. These pre-moistened wipes can keep you fresh after a long day of travel or work and are best for sensitive, stubbly skin. An extra bonus: the majority of deodorant wipes on the market like Whish Deodorant Swipes, $22 for a pack of 30, are formulated with antioxidants like chapparal extract, that inhibit hair growth, and protecting agents like seaweed and vitamin C for an added skin care friendly treat.
