Beauty Tip 1: Never Underestimate the Power of Moisturizer

Whether your skin is dry, normal or even oily, if you can only afford one skincare product, experts say, your dollars will be well-spent on a good moisturizer.

"Sometimes, all you really need is a good moisturizer and a mild cleanser, and you can take years off your face," says New York University professor Rhoda Narins, MD, president of the American Society of Dermatologic Surgery.

So what exactly is a "good" moisturizer? Dermatologist Charles E. Crutchfield III, MD, describes it this way: "It's a product that will do anything from gently adding moisture, to sealing in the moisture you've achieved, to helping your skin produce more moisture—and which type you choose should be based on your skin's individual needs."

Beauty Tip 2: Sunscreen Is Your Best Anti-aging Product

While most of us know it reduces the risk of skin cancer, did you also know it's an amazing beauty secret that can help keep skin looking young?

The reason, say experts, is that when sunscreen blocks out the sun's damaging rays, it also blocks their aging effects.

Sunscreen can protect your skin from these damaging rays, so that even if you do spend time outdoors, your face is less likely to give away your age.

Another option: Use your regular sunscreen before putting on makeup (it should go on first, before anything). Then, for touch-ups, use a light, translucent mineral powder to add extra protection throughout the day.

Beauty Tip 3: Choose Your Cleanser Wisely

Wash skin no more than twice a day and choose your cleanser wisely. The expert's three top favorites: Dove Unscented Bar, Cetaphil and Vanicream Cleanser.

Beauty Tip 4: Use the Right Tools for the Right Job

"Using the right brushes, the right application tools—it's key to making the products go on the way they are intended and to give you the look that you want. For a professional makeup artist, the tools are as important as the products," says Mordini, who has painted and puffed some of Hollywood's most famous faces.

Brushes should be soft and feel gentle on the skin but also have substance so the product can be moved to the surface of your skin. If you dip a brush in shadow or blush and the color falls off before you make it to your face, that's a bad brush, experts say.

Beauty Tip 5: Update Hair and Makeup Every 2 Years

"Ideally, your image, including hair and makeup, should be updated at least every two years—and sooner if the styles change dramatically," says Beverly Hills hair expert and QVC personality Nick Chavez.

By keeping your look current, Chavez says, you also look younger and more modern. "Nothing dates a woman more than outdated hair and makeup," Chavez says.
