Some scientists believe that while we sleep, our skin goes into repair mode. Clinique Smart Night Custom Repair Moisturizer, $57, capitalizes on that concept. It's loaded with glucosamine, hyaluronic acid, peptides and botanical extracts to plump fine lines and keep skin moisturized all night long. And it contains murumuru butter — a fatty acid-rich ingredient derived from the murumuru palm in Brazil — to strengthen and repair the skin's barrier.
