Beauty editor confession: I'm a huge skeptic when it comes to beauty products. Why? I've been duped too many times by the lure of pretty packaging and over-the-top claims. It's an unfortunate fact that sometimes labels exaggerate. I've never met a foundation that truly lasts 24 hours, a zit-zapper that gets rid of pimples overnight or a split-ends salve that magically repairs damaged strands.

But as a beauty editor, it's my job to separate the snake oil from the superstars. And in no category is this harder to do than anti-aging. When results are promised so far down the road, you want proof upfront that it works.

That's where science comes in. Clinical trials that show noticeable results get our attention. But no science is more respectable than Nobel Prize-winning research. These five skin-care products claim to do some pretty amazing things -- like actually halt the aging process -- but they also have some pretty convincing science to back them up. Here, the anti-aging products that are backed by Nobel-winning science.

The Product: Kate Somerville Age Arrest Anti-Wrinkle Cream

Cost: $90 for 1.7 ounces

Why: If you're skin-care-obsessed like us, you've probably heard of a little thing called telomeres. If not: Telomeres are the caps at the end of our chromosomes that protect them from unraveling -- like the plastic cap at the end of a shoelace. Each time cells divide, telomeres shorten. Once they get too short, our cells stop being able to divide and may even die. In layman's terms? "It's the aging process," says cardiologist Adam Splaver. The rate at which your telomeres shorten predict how quickly you'll age -- a.k.a. fine lines, wrinkles, sagging skin, you get the picture.

The Age Arrest line is based on Nobel Prize-winning telomere research that found that a certain enzyme, named telomerase, assists in preserving those DNA end-caps. In other words: with telomerase, your cells can continue to go about their business of dividing and remaining healthy, keeping your skin from degrading and growing old.

This cream boasts "Telo-5," which, while rather ambiguous-sounding, is a lab-created version of telomerase. Does it work? An independent clinical study suggests it does. In the study, 90 percent of women showed significant improvement in firmness and elasticity and 93 percent showed improvement in discoloration, skin tone, hydration and crow's feet and fine lines after just four to six weeks.

The Product: Dior Capture Totale One Essential Intense Skin Detoxifying Booster Serum

Cost: $125 for 1.7 ounces

Why: Don't believe the hype behind detoxification? Consider this: Nobel Prize-winning scientists have discovered that proteasome, a naturally occurring enzyme, can detoxify, or clean out, cells by breaking down the unneeded or damaged proteins that occur in aged skin. Dior One Essential works to stimulate the proteasome with a patented longoza extract, from a flower found in Madagascar. Removing the toxins that accumulate in the skin allow the skin to better absorb top-notch skin-care ingredients and restore skin's youthful glow. This serum claims to boost your other skin-care products' effectiveness by 400 percent. Targeted at individuals who live in polluted environments, Dior claims that this serum helps to remove some 7 billion toxins that accumulate in the skin. Consider it a hazardous waste disposal system for your skin.

The Product: YSL Beauty Forever Youth Liberator Serum

Cost: $205 for 1.7 ounces

Why: To understand how this product works, you need a little background on glycans, the sugar molecules that are found naturally in the body. You've heard that sugar is practically the devil in regards to skin health -- but these molecules don't come from cake, and they have nothing to do with raising your blood sugar. Glycans help skin cells communicate -- they sit on the surface of cells and act like antennae for skin cells. As we age, glycans (which also keep cells plump by attracting water) diminish, halting the skin's regeneration process. Enter: Glycanactif, a lab-formulated, patented complex created by L'Oréal (YSL's parent company), intended to replace some of the common glycans lost during the aging process.

Glycobiology research has been recognized by seven Nobel Prizes -- it's clearly regarded as an important issue when it comes to skin health. Glycanactif not only replaces glycans, it also encourages glycan production from the cell itself. Does it work? Clinical studies say that participants experienced a ten percent increase in epidermal thickness and skin was visibly less lined and plumper after one month.

The Product: Aromatherapy Associates Rose Infinity Serum

Cost: $214 for 1.69 ounces

Why: Like the Kate Somerville line, the Rose Infinity products work under the theory that the shortening of telomeres is the cause behind skin aging. This serum relies on hydrolyzed soy and yeast proteins, which help protect and rebuild telomeres. The soy isoflavones in this serum have been shown to significantly increase skin thickness -- a study of 20 postmenopausal women showed that skin volume increased by 11.2 percent over three months. Hydrolyzed yeast proteins, one of the active ingredients, delay the shortening of telomeres, as proved by three researchers (two of whom are women, natch) awarded the Nobel Prize in 2009.
