Sirtuins, naturally occurring proteins in the body that have been shown to delay the aging process, are exciting the researchers at Avon; they think these molecules are key to keeping skin looking younger, longer. Avon Anew Ultimate Age Repair Night Cream and Avon Anew Ultimate Age Repair Elixir ($34 and $54) contain a complex that researchers believe stimulates the production of sirtuins, resulting in firmer, smoother, and more evenly toned skin. (The elixir contains twice the amount of active ingredients and promises faster results.) We can't vouch for the increased sirtuin production, but after using the cream, our skin felt softer and luxuriously moisturized.
