Orchidée Impériale The Emulsion. The Emulsion Guerlain Orchidée Impériale is an emulsion that smartly adapts to oily or dry areas of the skin: the sebum-regulating zinc is encapsulated to absorb excess oil, while hyaluronic acid hydrates the drier areas, resulting in an even complexion. The nourishing and velvety texture provides a mattifying effect and a balancing effect. Apply the treatment with circular motions.
