Originally from the region of the Andes, polymnia has been used for centuries for its edible, tuberous roots. Their sweet tasting flesh is similar to the grainy texture of a pear. Research carried out in the past few years on the tubers has highlighted the presence of unique sugars: fructo-oligosaccharides (FOS). They are calorie-free (they are not absorbed by the body) and taste delicious. They also help the digestive system to work properly. In Clarins products, polymnia sugars help to the preserve the skin's natural moisture balance.
