Carrie Underwood lets us in on her skin-care sins in a promotional video for Olay. The blond beauty admits that before working with Olay, she would cleanse “with a washcloth and bar of soap and not think twice about it. What I did not realize is that I was taking off makeup, which was good, but I was leaving behind residue, which is bad.” Carrie says she uses the company's Pore Minimizing Cleanser + Scrub. “I’m exfoliating my face gently and I'm not leaving behind any kind of residue. My face feels soft and clean.

“I honestly think people would be surprised to know how simple my beauty routine is,” says Carrie. “It’s all about cleansing, UV protection, a little makeup and I’m out the door.”
