Celebrity derms and makeup artists -- most of whom have seen what late nights of socializing and long days at work can do to skin -- insist that moisture be a top priority. "Use the best product for your skin, not necessarily the most expensive," says celebrity makeup artist Patty Bunch. Since smog depletes your skin of moisture-rich antioxidants, consider popping open a skincare capsule of Vitamin E or C to supplement the loss. (Tip: You can even use it as a primer under makeup.)

Eat more greens.
"By having a diet that is very rich in greens [and/or] supplemented with green pounder drinks you can get in health food stores ... you raise your body's PH balance, which leads to anti-aging," says dermatologist Dr. Jeanette Graf. On the other hand, acid producers like caffeine, alcohol, dairy and cigarette smoke need to be limited as they have the opposite effect.

Baby your blemishes.
When you're exposing skin to city dirt and grime, especially during sweat-filled summer months, a blemish (or handful of them) is bound to happen. Don't panic or pick; you'll get scars. Patiently wait it out and cover it with a sweat-resistant formula: Moisturize a clean blemish with a skin salve or balm like 100% Pure Organic Healing Moisturizing Balm, $25, then brush on concealer (like CHANEL Correcteur Perfection Long Lasting Concealer, $40). No time to wait it out? Head to your derm for a hydrocortisone injection, which can safely deflate a monster zit within 24 hours.

Sleep more.
Stress is a no. 1 factor when it comes to how your skin looks. Since it's hard to get a good night's rest in a bustling city, and smog already causes skin cells to react as if they are facing stress, getting a good night's sleep becomes doubly important (not to mention a cure for a sallow, sleep-deprived complexion).

Use light reflectors.
When your skin isn't cooperating but you need to fake a healthy glow, rely on a prebase serum or gel with light reflectors in it (like CHANEL Le Blanc de Chanel Sheer Illuminating Base, $45). Used as a primer, its shimmery, iridescent finish gives skin of any age a glow so subtle that no one will know it's not real.
Bright lights, big city ... big zit? Several studies, including one published in the "Journal of Investigative Dermatology" and another in the "International Journal of Cosmetic Science," have long suggested that smog could be stressing out -- even damaging -- human skin cells, depleting them of valuable substances like Vitamin E. So what's a city girl to do? Adopt these 10 lifestyle habits and send those pesky skin irritants packing.
