Our perfume contains apple extract, grapefruit oil, and green lemon oil. It can stimulate the areas of the brain associated with feelings of fullness and satisfaction, and send the message of fullness to the brain to stop eating. The way to use it is simple: spray perfume on your body when you want to eat, or you can spray perfume in the snack cupboard or pantry. By stimulating the sense of smell, you can achieve satiety.
