CO2 Perfume is described as a floral and a bit woody fragrance that combines top notes of rosemary, artemisia and green leaves with a heart of peony, vanilla and rose, and a gentle, musky base. It was introduced by Jeanne Arthes and it is a clean and refreshing scent that will remind you of wind rustling through green leaves. CO2 is highly recommended for daytime wear, especially at the office, where people will notice you as an elegant and tasteful woman.
