Walking down the skin care aisle of the local drug store, one would notice numerous wrinkle cream products. Are the benefits touted by these cream manufacturers just marketing tactics? Are some of these wrinkle creams better than others?

We took a close look at some of the most common ingredients of the best wrinkle cream products on the market, and discovered some surprising results. It turns out that the answer to the question, 'why are some wrinkle creams better than others' is that some ingredients work better than others.

What follows is our guide to the top six ingredients found in wrinkle creams, all of which have been shown to reverse the signs of aging. With this information at your fingertips, you can finally answer the question, "why are some wrinkle creams better than others".

Retinol: A type of Vitamin A that has been proven to aid in the fading of wrinkles. This has been in wrinkle creams for years, even in the newest products. Retinol neutralizes particles called 'free radicals: that break down your skin and cause it to lose elasticity.

Coenzyme Q10: this is a naturally occurring type of enzyme. It acts like a 'food' for cells, helping them regulate their production of energy. Studies have shown that it can relax those tiny lines around your eyes by helping make the skin cells around your eyes more healthy.

Tea Extract: Drinking tea provides antioxidants to our bodies, which promotes energy and health. Tea extract does this to skin when directly applied, reducing the inflammation that causes skin damage.

Alpha hydroxy: this is a mild acid that comes from fruit. It helps to strip away the very top-most layer of your skin (exfoliation) and therefore reveal the healthy beautiful skin underneath it. Exfoliation is great for our skin when we do it periodically, because it helps promote the growth of healthy skin and the removal of dead skin.

Copper peptide: this is an essential nutrient that our bodies need to be healthy. Copper particles are especially great for our skin because they increase the speed at which it heals from wounds. Over time, tiny invisible wounds caused by environmental conditions damage our skin and speed its aging, since it is never able to heal properly.

Kinetin: this is a natural substance that helps make living things grow. It helps with wrinkles and brown spots on the skin. Scientists believe that it works by making our skin and the collagen underneath it grow more quickly, therefore healing it and evening out wrinkles and age spots.
