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: 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 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 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.
