We've all heard of that mythical spring, a drink from which gives you glowing skin, glossy hair, youthfull strength and flexibility - The Fountain of Youth. If such a fountain existed, it would likely have long ago been drained and bottled.

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.

It doesn't help to look at a picture taken of us in our youth. We see the soft, smooth skin and the cracks, lines, and wrinkles we see in the mirror today are not to be seen in the picture. So we look to the shelves of our grocery store, drug store, or health foods store where we find the anti-aging creams designed to do battle against our laugh lines and crow's feet.

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.

Asking the question leads to gaining the facts you are after. Asking "Which wrinkle cream is best?" leads you to doing some investigating. The result may not be as good as the Fountain of Youth would provide but may still be the best choice available.
