The iconic Double Serum is now also available in a new light texture, with the same proven results on the signs of ageing. With a new 50% lighter feeling, this formula contains three new revolutionary lightweight oils, that partially evaporate on contact with the skin, leaving no oily finish, just a smooth lightweight feel. The unique dual formula combines the identical 21 powerful plant extracts as the original Double Serum that help boost the 5 vital functions of the skin - regeneration, nutrition, oxygenation, hydration, protection - and act on signs of aging. The bottle's rotating push button delivers a made-to-measure dosage of serum. The technological and eco-designed packaging prioritise responsible materials and limits waste. Double Serum, only lighter, is perfect for combination to oily skin types, or for those who prefer a lighter weight texture. Apply morning and/or evening to the face and neck, before day/night cream. After selecting the level of dosing desired, mix and warm the serum in the hands to bring to skin temperature and to facilitate absorption. Then place the serum on the middle part of the face, pressing outward over the face and neck using the entire surface of the hand. Apply using draining pressure from the centre of the face outward beginning on the cheeks, then the forehead and neck, to avoid pulling tissues, enhancing drainage and preserving youthful-looking features
