Skin Caviar Harmony L’Extrait, infused with Caviar Infinite, is an intensive extract that restores the harmony of youth by strengthening and re-densifying skin's vertical pillars. Through groundbreaking research, La Prairie has created Caviar Infinite, an ideal blend of caviar components augmented to target skin's vertical pillars and underlying skin structure. La Prairie Skin Caviar Harmony L’Extrait is a uniquely intensive yet lightweight resculpting serum that strengthens and redensifies the skin for fewer visible lines and wrinkles. This resculpting extract rejuvenates the skin and reduces fine lines and wrinkles for skin that appears more lifted, tightened and toned. This lifting serum features a texture that absorbs quickly into the skin and is designed to be layered underneath another serum. Skin Caviar Harmony L'Extrait introduces Caviar Infinite, a revolutionary ingredient designed in partnership with a Swiss bioanalytical laboratory. Made in Switzerland.
