Model Cindy Crawford says her top tip to stay beautiful is to be happy.
"The biggest secret really is just being happy, because that shows on your face more than anything. If you're going to have lines, you might as well have smile lines," Crawford told PrestigeHongKong.com, reports femalefirst.co.uk.
However, she adds that a sunscreen and eye cream, can add to one's beauty.
"What I've learned from taking care of my skin for over 20 years now is that it adds up. At 50 you're going to be like, 'Wow, I'm so glad that I started using sunscreen or a good eye cream.' I don't smoke and I drink a lot of water, so I'm pretty healthy," she said.
