Prevention magazine put the leading anti-aging beauty products to the test once again this year, revealing seven products deserving of the “Defy-Your-Age” seal. Winnersinclude Roc Multi Correxion Skin Perfecting System, Avon ANEW Reversalist Illuminating Eye System, Skin Effects by Dr. Jeffrey Dover Glycolic Peel Kit and Olay Definity Neck & Chest Daily Restoration Treatment.

To determine the winners, Prevention enlisted seven dermatologists to test the claims of the 35 most innovative products of the year on a group of 175 women, ages 40-plus, for a period of up to eight weeks. The doctors then employed state-of-the-art equipment like the Visia Analysis Machine to measure which products best delivered on their claims using before and after skin analysis. The teams investigated seven categories of products including eye and night creams; lip, neck, and brown spots products; peel treatments; and day lotions with SPF; this year’s winners are all available for less than $50.

Said Prevention Editor-in-Chief Diane Salvatore, “Prevention readers are smart and stylish women who care about feeling—and looking—their absolute best. Readers have come to count on Prevention to sort through the new beauty choices that flood the marketplace every year, to report on which ones really deliver and should be on their list of must-haves. ‘Prevention-tested’ means the product has gone through rigorous testing, and that’s why it’s so exciting to showcase this truly outstanding list of the ‘Super Seven’.”

Here is the complete list of Prevention’s “Defy-Your-Age” Beauty Award winners for 2010:

* Best Brown Spot Fader: RoC Multi Correxion Skin Perfecting System – This three-step system, which includes a cleanser, day cream with SPF 30, and night cream, contains retinol, soy, and vitamin C—ingredients proven to improve skin tone. Testers were thrilled with how it despeckled skin. ($50; drugstores)

* Best Day Cream with SPF: HydroPeptide SPF 30 Anti-Wrinkle Skin Enhancing UV Protection – A moisturizer that camouflages redness and blotchiness and produces a radiant glow. The product’s other winning attributes—long-lasting hydration, noticeably lighter brown spots, and decreased sensitivity—are due to an all-star lineup of rejuvenating ingredients like glycerin, zinc oxide, vitamin B3 and antioxidants such as green tea and açai berry. ($40; hydropeptide.com)

* Best Night Cream: Vichy LiftActiv Retinol HA Night – This potent potion works fast. Overnight, testers noticed brighter skin—and things just got better with time. Testers also reported a dramatic improvement in wrinkles and brown spots. Judge Mary Lupo, MD, credits retinol, “a top gun” in OTC anti-agers, for the dramatic results. ($42; drugstores)

* Best Eye Cream: Avon ANEW Reversalist Illuminating Eye System – This innovative, two-step regimen is the perfect counterpunch to the signs of aging that often attack this area. The activating cream triggers production of collagen, which improves the look of crow’s-feet and undereye circles; the accompanying “brightening veil” instantly softens imperfections with light-refracting mica, blurring polymers, and silica particles. ($30; Avon Representatives and avon.com)

* Best Skin Peel: Skin Effects by Dr. Jeffrey Dover Glycolic Peel Kit – This treatment instantly boosts brightness and smoothes skin thanks to glycolic acid, which sloughs dead cells off the skin’s surface. The post-peel soothing pads help ensure that skin is left beaming, not blotchy. ($25; CVS stores)

* Best Lip Treatment: PCA Skin Peptide Lip Therapy – With top ingredients like sunflower seed oil and shea butter, this ultrahydrating treatment is the balm for making lips softer, smoother, and plumper! Its tingly peppermint oil increases blood flow to further enhance volume and restore lips’ natural healthy color. ($20; 877-722-7546 for purchasing info)

* Best Neck and Chest Cream: Olay Definity Neck & Chest Daily Restoration Treatment – This luxurious cream, loaded with ingredients like glycerin, dimethicone, and panthenol, drenches this often-neglected area with moisture, and evens skin tone, diminishing the appearance of sun spots and discoloration on the neck and chest with a tone correcting clear gel complex.
