Diaz has never been all that open about her problems with acne, but she has acknowledged it on a few occasions in the past. Having some of the best make-up artists and Photoshop experts in the world working on your behalf sure makes it easier to cover up problem skin. Diaz has said that quitting smoking was one thing she did that definitely helped improve her skin. She also reports that it improved her skin significantly once she stopped eating a cheeseburger and fries every day.
