Smell sense is still a mystery in some ways and can be tricky sometimes. That’s why when you stop smelling your fragrance you start wearing more quantity, hoping to smell it again. You even ask people; do you smell my perfume? Normally the answer is yes, so… where’s the problem? Most probably it’s just your nose has grown used to the scent. It’s precisely this smell particularity what’s related to its primitive function as a danger warning, just like it happens in the wildlife. That’s why our brain assumes a smell is our own when we sense it regularly, as a way of surviving. The same way happens with our home scent, we assimilate it to be able to detect when something is different and avoid possible dangers. That’s why we can easily smell smoke or rotten food. For all those reasons we tend to get used to our fragrance when we wear it often, even when there are unpleasant smells or a lot of information around us like in streets or the underground. Our brain gives us the impression that scents have disappeared when odor molecules are still present, through a mechanism that filters necessary information.
