La Prairie Cosmetics. SKIN CAVIAR Luxe Body Souffle. Very soft textured body cream designed to offer a complete treatment for your skin. It contains caviar that strengthens the tissues and keeps hydration levels stable; willow bark extract, which exerts a very gentle exfoliating action; and extracts of algae and caffeine, which reaffirm and stimulate circulation. The result is silky, light and beautiful skin. Apply in the morning or at night, after the shower to achieve greater moisture retention in the skin.
