Estee Lauder’s Advanced Night Repair Overnight Treatment is a high-performance leave-on mask with a breathable, second-skin texture that melts on contact to seal in nighttime skin care and support repair while skin rests. Lightweight yet protective, it stays put through the night to help lock in moisture and reinforce comfort.Powered by multi-molecular weight hyaluronic acid, sodium hyaluronate, polyglutamic acid (PGA), a 13% lipid infusion, and Night Peptide, it delivers deep hydration to plump the look of lines and strengthen the skin barrier as it recharges. Clinically shown to boost Visible Energy by +28%, Moisture by +58%, and Barrier by +40%, it supports intensive moisture and barrier recovery for all skin types, including sensitive and post-procedure skin. By morning, skin looks more radiant and recharged, with results many users describe as feeling like two nights of sleep in one.
