When you look in the mirror, do you see fine lines and wrinkles? If so, you're not alone. Wrinkles are a natural part of the aging process, but age is not the only reason that people get wrinkles. They can also be caused by exposure to UV light from the sun, smoking and continued facial muscle contractions, often referred to as frown lines and crow's feet [source: Bernstein].

Whatever the cause, people have fought against the aging process for thousands of years. In the 15th century, Spanish explorer Ponce de Leon searched Florida looking for the elusive fountain of youth. Drink the water, and you'll be forever young. Obviously, he didn't find this miracle tonic, or we would all be wrinkle-free. Even the stunningly beautiful Nefertiti, ancient queen of Egypt, couldn't avoid a few wrinkles here and there -- a 21st century CT scan showed that the iconic sculptured bust of the infamous queen was retouched to preserve her beauty [source: Discovery Channel].

Although there is little we can do about the aging process, today consumers have numerous choices for fighting wrinkles. Many people choose popular wrinkle-minimizing makeups over more costly anti-wrinkle treatments, like Botox injections, laser treatments and face-lifts. There are countless cosmetic products on the market, including foundations, lipsticks and blushes, many of which contain wrinkle-fighting agents. The ingredients in these products help moisturize your skin and make it feel firmer, giving it a more youthful appearance. Some cosmetic companies claim that their products fight free radicals, the unstable oxygen molecules that contribute to aging. Others maintain that they improve your skin's circulation or make skin more elastic by increasing collagen, a natural protein in the body that helps make your skin smooth.

The types and amounts of ingredients in wrinkle-minimizing makeup are crucial to the makeup's effectiveness. So before you purchase any wrinkle-minimizing product, you need to be armed with knowledge about what these ingredients are and what they do.
