Actress Rooney Mara says she believes in natural beauty and doesn't wear much makeup in everyday life.
The "Side Effects" actress also admits that she is "horrible" at applying cosmetics herself.
"For me, natural beauty is something I've always been drawn to. I still don't really wear makeup in my everyday life and I would be horrible at even trying to do it to myself," femalefirst.co.uk quoted Mara as saying.
The 28-year-old just uses sunscreen lotion and keeps a check on her diet.
"This is going to sound so simple, but sunscreen... I always wear sunscreen. I also find that what you eat is the best beauty secret - it sort of starts from the inside out," she said.
Mara, face of fashion house Calvin Klein's new perfume Downtown, said their designs reflect her own simplistic style.
"The Calvin Klein collection is really quite similar to how I dress in my personal life. It's very minimal and clean and comfortable, but very modern at the same time," she said.
