Waldorf explains, "Pores don't expand, but they may look more prominent as cosmetics and creams slide in [your pores] with sweat and mix with dead skin cells and oil."

The Fix: She recommends using products containing retinoids, alpha-hydroxy acids and salicylic (like Murad AHA/BHA Exfoliating Cleanser, $35), which improve cell turnover to minimize the look of your pores.

"Physical exfoliants are also helpful," she says, recommending the use of a product like the Clarisonic Cleansing Device, $99, once or twice a week.

We're all familiar with the dry, cracked lips of winter. But too much sun and dehydration can leave lips rough, which is not ideal for wearing lipstick.

The Fix: To prevent dry, chapped lips, drink more water and apply SPF-infused lip balm like Supergoop! Acai Fusion Lip Balm Broad Spectrum SPF 30, $8.50.

At night, exfoliate your lips with a good scrub (try Fresh Sugar Lip Polish, $22.50) and follow up with a moisturizing balm that contains ingredients like hyaluronic acid or petrolatum (try Smith's Rosebud Salve, $6).

All the time you spent lying outside, and those cute sandals that left your feet exposed to the sun are to blame for dry, cracked feet by summer's end. Celebrity manicurist Skyy Hadley, adds, "Open-backed sandals and flip flops are the main culprit for causing cracked heels as the material on the shoe rubs around the edge of the heel."

The Fix: To fix up your feet, Hadley says milk pedicures will save the day. All you need to do is mix equal parts hot water with milk and add some sugar crystals. "This will moisturize your feet and prevent calluses," she explains. Another of her must-dos: Exfoliate and scrub your heels one or two times a week before bed. When you wake up, work moisturizer into your feet to keep skin soft and prevent cracking. Hadley suggests using lotion with shea butter, like L'Occitane Shea Butter Foot Cream, $28, or Vaseline Pure Petroleum Jelly, $6.49.

After soaking up sun during your final days of summer fun, you may be left with painful-to-the-touch, red, inflamed skin.

The Fix: Waldorf recommends popping a couple of aspirin or Advil to help minimize the pain and swelling of your sunburned skin.

She also suggests applying cool compresses to the burned areas and following that up with a topical hydrocortisone cream like Cortizone 10 Maximum Strength, $8.99, to further soothe your skin and speed up the healing process.

The Fix: If your painful sunburn has turned your skin into a peeling mess, Waldorf recommends adding mega doses of moisture. If the area is irritated, she suggests applying Vaseline Pure Petroleum Jelly, $6.49, to the area.

Once the irritation has subsided, "switch to an alpha-hydroxy acid moisturizer," she says (try Amlactin Ultra Hydrating Body Cream, $14.99). It will help gently exfoliate the peeling, flaking skin while deeply moisturizing.
