What It Is: The refill to the fresh and light serum, composed of 95% naturally-derived ingredients, with an ultra-fine texture that melts into skin, visibly amplifying 10 signs of youth and reviving 6 factors of light. What It Does: After 20 years' research, Guerlain has created Orchidée Impériale Gold Nobile, revealing a new cosmetic rejuvenation pathway for skin. Guerlain Research has concentrated the powers of an extraordinary orchid, the Gold Nobile orchid. Endemic to the Himalayan region, it has inherited the ability to combine several photosynthesis mechanisms to turn the sun's light into real vital energy. The light diffused by its petals is therefore more intense than those of an ordinary white orchid.
