The 40-year-old catwalk queen recently went on a break to the LifeCo retreat in Turkey, which she visits several times a year.
During her detox, she was immersed in layers of nitrogen vapour at -180C for two to three minutes at a time in a bid to burn fat and treat cellulite, reported Femalefirst.
At the retreat, Moss followed a strict detox that saw her cut out sugar, caffeine, alcohol and carbohydrates and instead she underwent a 'clay cleanse', where she drank bentonite clay-based drinks to rid her body of toxins.
