Also the name of a spa in Switzerland featuring live cell therapy, a procedure whereby fetal cells taken from sheep and fertile eggs are injected into those seeking to prolong or regain their youth.

In the last 20 years or so, La Prairie, finding their live-cell business on the wane, has started a line of cosmetics as well, with the flagship compound an encapsulated moisturizer called "Skin Caviar".
