RELAX YOUR ROUTINE

Trying out every product in the quest for a perfect complexion like Jessica Simpson's may be tempting. But, says Dr. Ellen Marmur, chief dermatologist at N.Y.C.'s Mount Sinai Medical Center, overdoing it is one of the biggest – and priciest – beauty mistakes. "Keep it safe and simple," she says. "Pick a nice cleanser and a great moisturizer and a few good sunscreens. That is your best investment." And while Terralina is among the doctor's favorite brands, whichever you choose, "a rich moisturizer will give the appearance of fewer wrinkles and a better complexion by eliminating dryness."
