Revitalize your skin while you sleep with the Yves Saint Laurent Pure Shots Night Reboot Serum. The core product of the Pure Shots range, Night Reboot is designed to reduce signs of fatigue from the first application. This innovative formula is enriched with Selenicereus flower extract, a rare species of cactus that blooms for only six hours each year, releasing a natural sugar. The rare sugar from this plant was obtained through a cold and long extraction process developed for YSL Beauty to preserve its effectiveness and freshness.
