We've all heard of the Fountain of Youth - that mythical spring that grants eternally supple limbs, dewy skin, and vibrant hair to all who drink from it. Unfortunately, such a fountain is only the stuff of legends, or it certainly would have been drained by now!

We would all like to recapture our youth, if not eternally at least for a time. While The Fountain may be the stuff of legend, we've created a variety of products designed to accomplish much the same. Anti-aging products ranging from vitamins to wrinkle creams and a host of other concoctions sell at a brisk pace as not just women but men as well try to keep their youthful looks for many years to come.

We look in the mirror and take careful note of the crow's feet, laugh lines, worry lines, wrinkles and creases that we've been collecting over the years. Like rings on a tree, these lines and creases serve to highlight the fact that we are getting older. It doesn't help to look at a picture taken of us at a young age in which none of these signs were visible. A steady stream of anti-aging moisturizers have entered the marketplace, "guaranteed" to do effective battle against the dreaded crows feet and other signs.

Of course, consumers are frequently dubious of any product that makes such claims, and with good reason. What are these magic ingredients, and how do they work? Can anyone really bottle the freshness of teenaged skin? How can you tell which is the best wrinkle cream?

It's important to know about the ingredients in various anti-aging creams before purchasing. So, why are some wrinkle creams better than the others? The active ingredient in many wrinkle creams is retinol, which is a form of vitamin A. Retinol is effective in making wrinkles less noticeable, because the skin absorbs the vitamin A and uses it to make new surface cells. It also increases the amount of collagen in the skin, which improves elasticity.

Whereas retinol functions to reduce the severity of wrinkles, another popular ingredient is alpha hydroxy acid, AHA. AHAs chemically peel away the outer layer of skin. The concentration is very low to prevent serious damage, so the peeling effect while slight, adds a glow the skin as new cells beneath the peeled away dead cells become visible.

Two products may claim to contain the above mentioned active ingredients yet do not necessarily provide the same results. The answer is often found in the degree of concentration of the active ingredients. One product may contain only a trace of retinol. A second product, containing a much higher concentration of retionol mayingedients are present.

If you're in the market for an anti-aging cream, make sure you have the facts. Now that you've asked, 'Why are some wrinkle creams better than others?,' you've armed yourself with the information you need to discover the Fountain of Youth for yourself!
