Made by an American company Deo Perfume, the perfume candy once licked releases rose scent through the pores of your skin. The body can't break down the chemicals in the sweet so they have to be discharged via the skin.
Made from geraniol, the sweet which lasts for 6hours, (I learnt) tastes like tangerine. It is widely accepted in America, a bag costs $10, it will be launched in the UK next year.
