The first step in Guerlain's Orchidée Impériale Age-Defying Radiance Ritual, the Radiance Essence-in-Lotion contains age-defying powers. Employing two technologies derived from orchids – Orchid Noble Light and Cell Respiration – the serum gets to work quickly, fighting dullness and improving any physical signs of ageing while simultaneously infusing skin with a blast of moisture and restoring its elasticity.
