Reduce Wrinkles

Every time you change your facial expression, be it furrowing your brow or cracking a smile, you break down the collagen in your skin, leaving it less firm; that, in turn, leads to fine lines and wrinkles. No wonder, then, that the latest anti-aging products are aimed at boosting collagen production. They're using potent ingredients, like hyaluronic acid, the same substance found in the injectable fillers Restylane and Juvéderm, which can be effective in topical form: "It temporarily fills lines by hydrating and therefore plumping up the skin," explains dermatologist Neil Sadick. Another hot item to look for on your moisturizer's label is algae, a powerful antioxidant that helps the skin repair itself.

Reduce Discoloration

Brown age spots "are inevitable for anyone who is exposed to the sun," says Gerald Imber, M.D., author of The New Youth Corridor. But a new generation of moisturizers with high-potency Vitamin C, which fights sun damage, helps to prevent discoloration and even out skin tone. Botanicals like licorice root and citrus peel have also been found to "selectively target cells that create pigment," says Imber, so look for skin brighteners that have these ingredients.

Hide Pores

Not only does the breakdown of collagen cause wrinkles (see previous page), it also makes pores appear wider. Once that happens, "there's nothing you can do to permanently shrink them," says dermatologist Francesca Fusco—though a slew of new, at-home exfoliating products (which remove pore-widening blackheads and debris) can help pores look smaller. Deep cleansing brushes (like the one above) mimic the effect of a salon skin-resurfacing treatment, while products with detoxifying botanical ingredients like white clay and rose extract are gaining popularity in masks and serums.

EAT FOR BEAUTIFUL SKIN

Dr. Howard Murad, author of Wrinkle-Free Forever, shares his top foods for skin

GREEN TEA

Packed with powerful antioxidants (which strengthen cells), "it may help minimize sun damage," Dr. Murad says.

POMEGRANATE

This fruit has so many antioxidants, Dr. Murad says, adding that his research shows its extract can boost the body's natural sun protection.

DECAF COFFEE

Java beans are a source of antioxidants, but stick to decaf; too much caffeine can disrupt your sleep, leading to dryness and fine lines.

CELERY STICKS

To stay hydrated, Dr. Murad advises, "eat your water, don't drink it," to get the added benefit of vitamins found in raw veggies like celery and carrots.
