Pioneers in nighttime repair, Estée Lauder was among the first to understand the importance of skin’s 24-hour circadian rhythm and how clock genes are critical to the synchronization of natural skin repair and protection. Estée Lauder scientists continued expanding upon a decade of expertise in the fields of DNA and skin circadian rhythm research, and in a beauty industry first, Estée Lauder published data from a metabolomics study in collaboration with a leading biotechnology company. The study identified over 300 biomarkers on skin which showed the skin’s activities during day and night and revealed that there is an ideal skin rhythm of protection by day, and repair by night. It also demonstrated the ability of Estee Lauder’s #1 repair serum, Advanced Night Repair Synchronized Recovery Complex II, to improve the natural rhythm and repair activity of key metabolites tied to skin’s appearance, reduce environmental irritation, improve skin’s protective ability, and the improvement of signs of aging in mature skin.

Patented until 2033, Advanced Night Repair’s exclusive Chronolux™ Bio-clock Technology combines potent Catabolysis and Chronolux™ technologies to maximize skin’s natural power to protect by day and repair by night for more youthful, radiant skin. This award-winning serum reduces the visible impact of multiple visible aging assaults of modern life – lack of sleep, blue light, pollution, UV and ozone – for skin that feels smoother, hydrated and stronger, and looks more radiantly translucent.
