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!

Who wouldn't want to recapture their youth - or at least preserve it as long as possible? There is a wide variety of products, from wrinkle creams to vitamins, designed to do just that. The brisk sales of these anti-aging products demonstrate that, indeed, many women (and men!) intend to keep their skin looking as youthful as it can, well into middle age.

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.

Now most consumers are probably a bit suspicious, perhaps very suspicious of the claims made for the products on the shelves. Some of the "magic" ingredients are well known, others are not. In any event a good question to ask is how is the product going to react on my skin? There does not seem to be a simple solution to what is really the best product for the individual.

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.

Reduction of wrinkles is one step towards achieving more youthful skin. Another popular active ingredient is alpha hydroxy acid - AHA. AHA is a peeling agent. It is present in a very low concentration to avoid damage to the skin, AHA removes the dead skin cells at the surface, exposing new cells beneath. The result is the adding of a glow that we associate with youthful skin.

The mere presence of one or both of these active ingredients does not answer the question of which product is better. The degree of concentration of the active ingredients is much more likely to determine the effectiveness. A product with a higher concentration of retinol may be much more effective in producing a more youthful look than a product containing only a small amount of retinol.

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!
