THE SECRET behind actress Salma Hayek’s ever glowing skin is a juice cleansing diet, which she has been following over the years.

“I’ve been doing juice cleanses for 15 years,” Hayek said. The 43-year-old star has now collaborated with pal and professional juicer Eric Helms to create ‘Cooler Cleanse, a three or five-day juice detox delivery program, Us magazine reported.

“If I’ve been indulging in rich foods, a cleanse is a wonderful way to hit the reset button,” Hayek said. The two taste-tested each blend and worked with several nutritionists and vegan chefs to develop the juice and raw-food menus.

The detoxers eliminate processed foods, caffeinated drinks, alcohol, dairy products and sushi. Those on the program also receive a home delivery of six drinks, including almond milk, watermelon and lime, that add up to less than 1,200 calories a day.

“I always lose weight, my skin glows when I finish day three. And it inspires me to think about what I put in my body,” Hayek said.
