Guerlain Orchidée Impériale Sleeping Serum (30 mL) is an overnight regenerating treatment designed to combat “sleep wrinkles” and morning puffiness. Powered by a potent orchid duo and Night Cell Respiration™ technology, this micro-emulsion serum delivers enhanced cellular rejuvenation during your skin’s nightly hypoxic phase. A soothing plant extract supports firmness and decongestion, helping to restore a smooth, radiant complexion by morning. The formula’s ultra-fine droplets penetrate deeply, and when paired with the L‑Roller massage, provide a concentrated and sensorial overnight recovery experience.
