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?

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.

Coenzyme Q10: This enzyme, natural, not manufactured, acts as a food for skin cells, aiding in the regulation of their energy production. Studies show it relaxes the small lines around the eyes by making the skin cells healthier.

Tea extract: this is one of the newest ingredients in wrinkle creams. Just like drinking tea provides you with antioxidants that help promote whole-body health, give you energy, and turn back the clock of aging, so too does using tea on your skin. Tea extracts also help reduce the inflammation that causes skin damage over time.

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 required of our bodies to stay healthy. Over time, tiny invisible wounds caused by environmental conditions, such as the Sun, or extreme cold, damage skin and speed up the aging, because skin does not get to heal properly. Copper peptides increase the speed skin heals from wounds. This process rejuvenates skin and allows the skin to heal from the environmental damages it faces daily.

Kinetin: This substance comes from a plant hormone that promotes cell division. Kinetin is used in wrinkle creams to fade wrinkles and brown spots. Scientists say it makes skin and collagen grow quickly, healing and smoothing wrinkles by increased cell growth, filling in the 'valleys'.
