1. She’s Authentic

Casta opened up about her career to Grazia. She says that she wants to be authentic in her career, and change the perception of how models are viewed. “The idea is to fight for the beauty. When I talk about beauty it's something profound, not something superficial. It's true I came from fashion but I also felt I fought for something. I met incredible people like Saint Laurent who taught me to how to fight for beauty – real beauty. I think that's why they came to me because they knew I was trying all those 20 years to be authentic and trying to break the code as a model.”

2. She Makes Working Out A Priority

For Casta, fitness is a priority. She tells Grazia that she always makes time for exercise in her schedule. “Sometimes I have to [work out]. I don’t want to like everybody but I have to and I’m a human being. I’ve always been a sports person anyway since I was a young girl; it’s good for the brain. I go to run, I do gym sometimes, I swim... I’m not a freak out with that.”

Casta toldHarper’s Bazaar in 2012 that she is an avid runner. “Ladies; we need to work out – there are no alternatives. I try to exercise as much as possible. I like to run, swim and walk rather than going to the gym. You can’t beat an early morning run to start the day. I am quite active, having children makes you that way because I’m always running around after them!”

4. She’s All About Self-Love

Casta is all about self-love and self-acceptance. She tells Grazia that she wants others to feel the same way. “You are beautiful in the eyes of someone without them looking at you. Beauty is something universal, it's not only one way of being. It's what I'm fighting for women to accept the feminity that they have. This is really important to me, [especially now that] I have daughters.

5. She Takes Care Of Her Skin

Casta has amazing skin, and she makes sure to take care of it. She shared some of her secrets with Into The Gloss. "Sometimes when I have puffy eyes, I take ice and put some rose lotion and a cotton pad all together, and put it on my eyes in the morning. I have a product for when the lips get dry…it’s papaya; Lucas Papaw Ointment... I love to use that product, but I can put it here too, on the eye. It can be a nice eye shadow, especially here, on the inner corner, to create light around the eye."
