What it is: A rich night cream and massage stone that leave skin deeply nourished while restoring youthful radiance.What it does: Enhanced with the exclusive Pure Gold Diffusion System, this rich balm amplifies skin's nightly regenerating processes. More than a gesture, it is a ceremony that envelops skin in a comforting embrace. Night after night, fragile skin is revitalized, replenished and restored from within. The scientists at La Prairie have designed a formula that brings a singular, energy-rich nutrient to the skin. This nutrient's use by devitalized skin is maximized thanks to the unique properties of the exclusive Pure Gold Diffusion System. The System delivers a three-peak action sequence to the skin. First comes the immediate deposition of gold on the skin's surface to offer instant radiance. An intense infusion of replenishing ingredients follows. Finally, a steady release of the replenishing ingredients linked to the gold particles deposited on the skin's surface completes the sequence.The Pure Gold Radiance Nocturnal Balm is housed in a reusable vessel. The metal casing and cap are designed to be kept indefinitely. By promoting timeless packaging whose most precious materials become replenishable vessels and by ensuring the recyclability of its vial, La Prairie commits to smart and sustainable design. How to use: Inspired by ancient rituals, the Pure Gold Nocturnal Ritual begins with a signature gesture using the Nocturnal Massage Stone. After cleansing and toning, the Pure Gold Radiance Concentrate, or alternatively, a small amount of the Pure Gold Radiance Nocturnal Balm, is applied to the skin as a base. A series of specially conceived massage strokes using the cooling Nocturnal Massage Stone follows. After performing the signature gesture, Pure Gold Radiance Eye Cream is applied in the undereye area. Finally, the skin is cosseted with the application of the Pure Gold Radiance Nocturnal Balm. 2 oz. Made in Switzerland
