Molecule 01 consists of one single ingredient, also known as 'Iso E Super' in the fragrance industry. On its own it is less of an aroma than an effect. The wearer may notice a pleasant, subtle velvety-woody note which will vanish, then resurface after some time, but more than this, she or he will notice the impact it has on other people, because molecule 01 lends an indefinable radiance to the wearer.
