If you're like most people, you linger for a long time in the anti aging skin care aisle of your local drugstore, thinking to yourself, 'why are some wrinkle creams better than others'. You might even wonder whether the benefits touted by manufacturers of wrinkle creams is mere marketing.

When comparing the ingredients and researching what they do, we found interesting results. We have found that there is a difference in products and we also found 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: This has been in wrinkle creams for years. This type of Vitamin A is even in today's products because it is proven to neutralize 'free radical' particles that break down your skin and cause aging signs.

Co enzyme Q10: This enzyme occurs naturally. Q10 aids cells to regulate their energy production. Studies show that Q10 revitalizes the skin cells around your eyes, fading the tiny lines that will appear.

Tea Extract: The extracts provide antioxidants directly to the local area of the skin for which it is applied. Tea extract has been shown to sooth inflammation that cause long term skin damage.

Alpha Hydroxy: This is an acid used in exfoliation products, stripping the very top layer of dead skin to reveal more fresh, lively looking skin. Exfoliation is a great process to perform periodically. It keeps facial skin looking fresh and new.

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.
