Carrie Underwood will represent Olay's new campaign, "Challenge What's Possible," by representing a line of the skin care products later this year. The brand will also sponsor the fall dates of Underwood's Play On tour. "I am so excited to be associated with a beauty brand that has been trusted by women for more than 50 years," she said. Underwood said her mother, who used the company's products, encouraged her and her sisters to take care of their skin. "I love that Olay has managed to change with the times, yet stay in touch with women of all ages who want affordable skin care products that do what they promise," she said.
