On waking, the skin is fresh, unwrinkled and radiant*.
Thanks to a powerful duo of orchids, Night Cell Respiration™ Technology delivers all its age-defying power on the skin to combat the nocturnal hypoxia peak**, i.e. when the oxygen deficiency in the cells is at its height and the lying position compresses certain areas of the skin which hinders flow of fluids. The skin appears regenerated.
Combined with a plant extract with firming and soothing properties**, it helps combat wrinkles and face puffiness caused by lying down, so the skin looks rested on waking.
The revolutionary micro-emulsion formula is in perfect harmony with the skin: its microdroplets thinner than skin cells work inside the epidermis for a highly sensorial, diffusing action.
Coupled with the unique massage technique using the L-Roller, developed by experts at the Guerlain Institute, the smoothing and decongesting action of the Sleeping Serum is complete.

I - Place the fingers horizontally on either side of the face (parallel with the lower jaw).
II – Then, lightly tap with fingertips over the face, moving outwards from the centre.
III - Repeat this gesture moving up to the forehead. Repeat a second time.
IV - Apply pressure at points around the mouth, on the temples and between the eyebrows to boost cell energy.
Optimise the action of the Night Serum using the unique massage technique developed for the L-Roller: massaging along the lines of the lymphatic system has a smoothing effect which decongests the face.

TRANSPARENCY AND TRACEABILITY
We reveal the provenance of our raw materials and unveil all the stages involved in creating our products, "from the flower field to you".
During the night, hypoxia reaches a peak when the cells are insufficiently oxygenated. Another source of hypoxia is the pressure exerted on the face by lying down, compressing the flow of fluids deep in the skin and further hindering the supply of oxygen. The skin's environment is disrupted, causing puffiness and sleep wrinkles to form.
Combined with a plant extract with firming and soothing properties, Night Cell Respiration™ Technology helps combat sleep wrinkles and face puffiness: the visible signs of ageing are minimised, the skin appears regenerated, smoothed out and redensified.
