Well this is a peculiar scent indeed. Since the very opening it’s all about an odd chemical “thing” I can’t identify, a sort of glueish-waxy smell with grey musky hints blended with a sort of dark, dry, austere floral note, at the same time earthy and much abstract, “emptied” of any richness. I miss the amber note, while I get more some salty-dusty ambroxan (or other ambroxide-based components), with an overall sort of heaviness halfway concrete and mineral elements. On the base, something like Iso E or an equivalent dry pencil-sharpener feel. Words fail to describe this scent, as it’s basically something halfway wet soil and a medical ointment. Plus, an added “weirdness” value is the actual behaviour on skin, as you smell it more clearly in the sillage than on skin. Honestly, as much intriguing it may look on an intellectual level, it is so “I-don’t-get-it” that I can’t come up with a conclusion about L’antimatière. It manages to smell super clean and super safe, yet also cloying and almost threatening, carrying a subtle yet gloomy sort of medical feel. Worthy a try, as it’s a nice and creative job (the closest reference I can think of is Odeur 71), but I honestly can’t imagine who, when and why should wear this.
