"Drinking warm water and lemon every morning before my coffee and staying hydrated all day long really helps me stay healthy and helps my skin look its best," the "Hitch" star wrote. She calls water her top beauty must-have. "I believe it starts from within, so water, water, water," she wrote.
After water, Mendes is religious about working out. "I also exercise at least three days a week no matter how stressed I am," Mendes wrote. "I do cardio and light weights at least three times a week." As for her diet, "I think eating anything you want as long as it's in moderation is good," she said.
Check Out Your Drugstore
"I have so many!" she wrote. "My cosmetic line CIRCA was created for Walgreens because I felt there was a lack of amazing makeup at drugstores. I love Psssst dry shampoo. Great product and so inexpensive! As a body scrub, I love St. Ives Apricot Scrub. For skin, I love Queen Helene products."
Don't Forget to Look in Your Kitchen
Mendes has a simple solution for removing makeup. "Coconut oil on a damp washcloth," she wrote. Mendes couldn't say enough about coconut oil. "I use it on my face, my body and even my hair. Couldn't live without it!" she wrote.
For Oily Skin Like Hers
"I have oily skin and using witch hazel helps," she wrote. "For my oily hair I love dry shampoo. And in a pinch when you don't have any, I use baby powder."
For Keeping Your Makeup On
Mendes runs her shower after putting on her makeup. "Believe it or not, after I've applied my makeup, if I really want it to stay all day, I run the hot shower for a minute and I let the steam settle my makeup. I know it sounds weird but it works for me!" she wrote.
Don't Just Blush Your Cheeks
Mendes admitted that she learned to apply makeup by trial and error. "I definitely went too far for awhile! Between 16 and 18 I wore lipstick that was way too dark for me," she wrote. Blush is her beauty must-have, specifically "an amazing cream blush." She even created one for her cosmetic line CIRCA Beauty. "I use the color Portofino. It's amazing!" And she passed on a tip her own mother once gave her. "When applying blush or rouge of any kind, don't skip your nose," she wrote. "Make sure you apply it a little bit across your nose as well. It makes for a more natural, sun-kissed look."
You Don't Have To Spend A Fortune on Fashion
"Any time I go to a new place I always check out their Salvation Army and Goodwill. It's so fun. You have to be patient but it's always worth it!" Mendes wrote. "There's nothing more fun for me than putting my own modern twist on a vintage look. Mendes' own clothing label features dresses with a vintage flair. "I love (obviously) Sophia Loren, Monica Vitti, Gina Lollobrigida and Claudia Cardinale," she said about the 1940s and '50s Italian screen sirens who influenced her latest line. But she also appreciates "modern day Salma Hayek and Amber Heard," who she said, "have great fashion sense."
Don't Forget to Pamper Yourself
"I love trying new skin products and getting facials from different people so I learn all the techniques out there," Mendes wrote. But the most important, the new mom wrote, "Pamper day essential is sleep. xx"
