Thanks to its unique properties, gold as a radiance enhancer and vehicle for powerful active ingredients is particularly well-suited to devitalised skin – skin that is fragile, thin, dry and dull, deficient in nutrients. Both environmental conditions and physiological changes can contribute to skin’s fragile state. When skin is devitalised, it becomes less receptive to nutrients, leading to a slowing down of renewal processes. For skin to function more efficiently, it needs to be constantly exposed to active ingredients. To address this particularity of devitalised skin, La Prairie has developed a new Pure Gold Science Platform, designed to provide sustained delivery of two key replenishing active ingredients to compensate for the loss of receptiveness of the skin. The Pure Gold Diffusion 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 active ingredients follows. Finally, a steady release of the same replenishing active ingredients linked to gold particles deposited on the skin’s surface completes the sequence.
