1. She Uses A Variety Of Products

When it comes to skincare, Hudson believes in using a variety of different products. “Everything for me has always been about customizing my experience,” she tells Glamour. “I don’t just use one product. I use so many different products, and every day my skin is doing something different, whether it’s environmentally or hormonal. I try things all the time, I don’t know why I’m not a beauty blogger. I love using different products, I also think our skin needs different things. One skin-care routine, I don’t buy into it. That’s why I’ve never done a line myself. I would get bored of it.”

2. She Only Washes Her Face At Night

Hudson tells Glamour that she only washes her face once a day. She also says that she opts to do so at night. “​​My routine in the morning is easy. I don’t wash my face unless I had a night out that was a little more alcohol-heavy than I had hoped. I’ll use Egyptian Magic if I have any eye-makeup residue, anything that is sticky. But other than that, I don’t ever wash my face in the morning. I wash my face very thoroughly at night, and then I let my face oils actually hang out. I don’t want to strip my face too much.”

3. She Uses Face Masks

Another part of Hudson’s skincare routine is using face masks. “I formulated my mask so that I could use it at least three times a week,” she tells Glamour. “I love my masks so much, and I wanted one that I could customize, that I could make it heavier or something light. I find that when I’m working, I need masks more. I want to be able to apply it without having it be a once a week thing. If I’m on a set, my skin gets so tired, and it’s good to have something that can liven up your skin. So in that case, I would do a thinner version of my mask for three to five minutes.”

4. She Stays Hydrated First Thing In The Morning

Hudson broke down her daily routine and diet to Harper’s Bazaar. She says that she likes to start her day off by drinking water and celery juice. "First thing I do when I wake up is I stare at the wall and I think to myself, 'Am I going to get up now? Or am I going to get up 50-minutes from now? Or am I just going to go back to sleep?' And then I drink water. I do not eat first thing in the morning. The first thing I do in the morning is I have celery juice. And if anybody does celery juice on an empty stomach they know why—cause it's a joyous morning activity."

5. She Challenges Herself

Hudson makes sure to push herself when it comes to fitness. She says that she always wants to feel like she has accomplished something. "I'm definitely challenging myself in new ways, which I need," she tells People. "I like to be able to set new goals to see what I can accomplish, and I love how flexible and strong I feel after a good workout, especially doing Pilates, which never gets easier."
