Cook has incredible skin, and she broke down her skin care secrets to Us Weekly. She says that the first thing she does is wash her hands. She says this helps keep her skin clean. "Hopefully you're washing your hands throughout the day, but it's very important to get a nice scrub on before you touch your face because so much dirt and bacteria and grime sits in our hands under our fingernails. And we don't want that to get in our face."

In her Us Weekly skincare interview, Cook revealed some of her favorite products. She says that she loves to use serums on her skin, and uses two to get different things to happen. "Ever since I've added serums into their life, my skin has changed dramatically. Just like how you listen to your body and what you want to eat, you should listen to your skin and what it wants to be drenched in. I go between the The Ordinary Hyaluronic Acid and The Ordinary Niacinamide and Zinc, which has been instrumental in cleaning up my skin." 

Cook tells Us Weekly that one of her wellness and lifestyle secrets is staying kind, to both others, and herself. "I think that the best beauty tip that I've received and that I work into my daily practice is to be kind to myself, be kind to others. I think that the more that we tune into ourselves and listen to what we need, we truly will glow from the inside out."

Cook is open about her past struggles with body image and an eating disorder. She opened up about her struggles in an essay for SI Swim. Cook revealed that the ways she recovered from these struggles is by taking care of herself and listening to her body. "I slowly stopped being unhealthily concerned with my exercise routines. If I'm too tired, I give myself the day off and don't think twice about it. I slowly started learning how to eat healthily and consciously, but not obsessively. I try to eat clean but if I want something I will listen to my body and eat it."df44d9eab23ea271ddde7545ae2c09ec

In her SI Swim essay, Cook revealed her desires to change the fashion and pop culture industries. She says that she wants others to help spread healthy body values and appearances, and change beauty standards. "Our culture is not going to change overnight. Our image-driven society is one of the aspects of our world that make it so beautiful, if the contexts behind the images are mindful of the connotations the image can hold alone. The industry is changing for the better. I see that every day and I want to be a part of that change. I am seeing people on billboards that a wider range of human beings can identify with. I am reading important messages that go along with those beauty commercials that come on in between TV shows. I open up a magazine and there is emotional, social or political context to these images that have such a strong impact on our world."
