Hitting the gym after all that holiday feasting? Allure has the steps to keeping your skin in tip-top shape, even through a sweaty workout.

This time of year, my true vice and virtue come out: first, I stuff myself mad with cupcakes, chocolates, and other sweets that make their way to the Allure giveaway shelf. Then I drag myself to the gym. (And yes, there's a fair amount of self-loathing involved.) And lately I've noticed that while my body loves the extra energy that comes along with those 7 a.m. gym sessions, my skin does not. I want nothing holding me back from hitting the gym in 2013 (not the most novel resolution, I know), so I spoke with dermatologist Francesca Fusco to find out what I can do to help keep my physique fit and my skin squeaky clean. To get Fusco's skin-saving tips, just keep reading.

Take It All Off . . .
"The most common gym-related dermatoses [skin issues] I see are breakouts at the hairline, on the chest, and on the back," said Fusco. "Much of this is aggravated by excessive sweating, rubbing of material, and clogging with heavy comedogenic products. So always take your makeup off before working out." If you head to the gym right after work, throw some face wipes, like Say Yes to Cucumbers Natural Glow Facial Towelettes ($6), in your bag.

. . . And Put the Right Clothes On
"Wear a sweat-absorbing cotton tank and underwear to prevent skin from being irritated by synthetic material," said Fusco. "All that irritation can lead to butt, back, and chest acne."

Pull It Back — and Go Easy on the Product
"Wear your hair back off your face in a pony or at least pulled back with a band. If possible, don't put any leave-in products on your hair before working out. At the very least, try not to apply them within two inches of the roots or hairline so that the product doesn't migrate onto your skin and cause a breakout."

Use the Right Products Post-Workout
"Wash your face after you work out with a salicylic-acid-based cleanser," said Fusco. We like best of beauty winner L'Oréal Youth Code Foaming Gel Cleanser. "If your scalp is oily, use a product like Clear Scalp and Hair Therapy Total Care ($8) because it conditions without leaving oily debris behind." And of course, don't forget to moisturize.
