Actress Zoe Saldana goes back to basics when it comes to maintaining her flawless complexion. "I think washing your face twice a day at least is the most important thing to do, especially when you live in a city because there's so much pollution. Then there's moisturizing and wearing sunblock," Saldana tells InStyle. Instead of high-tech tools, she opts for something we all have at home. "My go-to tool I use is a small white towel to wash my face. I buy them in bulk every time I go to Costco."

"My mother was a hippie and very health conscious, so growing up she always encouraged my sisters and I to be as natural as possible," Saldana reminisces. "She gave us a book she bought at a garage sale about natural beauty remedies and we used to look up everything, like how to make masks out of oatmeal or give our hair highlights using henna tea or even rum. Once a year, we all still get together and put mayonnaise in our hair for old times' sake."

Last but not least, a positive attitude plays an integral role in Saldana's skin care routine. "I'm actually one of those people that really enjoys taking care of their skin. I don't see it as work, but really just as part of life, just like brushing your teeth."

With the press calls, premieres and onslaught of different time zones, actress America Ferrera's skin is constantly under different types of stress. "A really amazing facial is my beauty indulgence. I go to Linda Ross in Los Angeles, and she's my savior with all the traveling and flying and lack of sleep and stress. Her facials save me," the actress tells Allure.

When she isn't in Los Angeles, Ferrera practices her own form of skin care rehab that is readily available everywhere she goes. "Once I started drinking more water, my skin, hair and nails all flourished," the actress tells InStyle.

Singer Christina Milian knows her fair share about stage makeup, but when it comes to her personal beauty routine and pulling together a look as a busy working mom, there's only one thing that truly matters: "Lashes," she tells MO-AM magazine. "You can have a whole face of nothing, but if you put some lashes on, it saves the day."

While singer and actress Paulina Rubio boasts a radiant complexion in the spotlight, her skin-care secret is all about staying out of the sunlight. "I love the sun, but I can't tan anymore because I have spots. Even if I use sunscreen, the manchas come out," the 42-year-old singer revealed in Glam Belleza Latina magazine. To keep spots and hyperpigmentation at bay, Rubio exfoliates from head to toe with skin brightening products.

Rubio's other skin care secrets? "I have a lot of good habits, I drink a tequila once in a while, but not in excess, I do a lot of exercise, I love to sleep, and overall, love. Love is everything, almost more important than oxygen."

With high-fashion editorial shoots and dramatic runway makeup, Model Sessile Lopez's skin is often under stress and covered with an onslaught of products. How does she deal with breakouts on the go? "I take honey with me for a mask," she tells Essence.com. "It takes off the dead skin and leftover makeup. I also do an avocado-apricot-honey mask when my skin needs moisture."
