Beauty addicts have travelled from all over the world to sample the mineral-rich Dead Sea mud, which contains high levels of bromide, magnesium and potassium, and has long been celebrated for its therapeutic, skin revitalising and anti-inflammatory properties.
It is also widely believed that the Dead Sea mud can help cure common skin complaints such as acne, or help ease forms of arthritis.
Hmm, If only it wasn't quite so far away...
Note: smothering oneself in mud will (unfortunately) in no way guarantee the miraculous supermodel body of Bar Rafaeli.
