Retinol

• Retinol, a Vitamin A compound, is the most common ingredient found in wrinkle creams. Retinol is a non-presciption version of trentinol, a powerful Vitamin A-based topical cream that is prescribed by dermatologists. Retinol is a potent antitoxidant, which reduces the effects of environmental free radicals known to damage skin cells and contribute to wrinkles. Pregnant women should avoid using products containing retinol. In addition, retinol-based products will irritate sensitive skin.
  
  

Hydroxy Acids

• Hydroxy acids, such as alpha-hydroxy acids, beta-hydroxy acids and poly-hydroxy acids, are synthetic compounds that are similar to fruit acids. These hydroxy acids exfoliate the top layer of your skin, shedding dead cells and revealing the smooth, even skin underneath. Regular use of a cream that contains hydroxy acids will help you maintain a brighter complexion. You must use a sunscreen along with hydroxy creams, as newer skin cells are more vulnerable to sun damage. If you have sensitive skin, you may want to stick to products containing poly-hydroxy acids, as these are the least irritating of the hydroxy acids.
  
  

Copper Peptides and Coenzyme Q10

• Copper, when combined with protein called peptides, accelerates skin healing. Copper peptides are antitoxidants, which remove toxins from your skin, and increase your skin's production of collagen. Collagen plumps up skin cells, reducing the appearance of wrinkles.
  
  According to the Mayo Clinic, Coenzyme Q10, a substance similar to a vitamin, is effective at reducing eye wrinkles. It is non-irritating and can also help protect the skin against sun damage.
  
  

Kinetin

• Kinetin is derived from plant-based materials. Kinetin helps create collagen, reduces inflammation and helps your skin retain moisture. It may also improve the appearance of your skin, making wrinkles less pronounced. Since kinetin is non-irritating, it is a safe choice for those with sensitive skin.
