There's a precise scientific reason why a scent can transport you, in a fraction of a second, to a room that no longer exists, next to a person who is gone, to a summer twenty years ago. And there's an equally precise reason why repeating the same gesture every day — the same cream, the same fragrance, the same ritual — is not monotony, but one of the most effective ways the human brain knows to calm itself.

Essenza Lago di Como is born precisely at the intersection of these two neuroscientific truths: artistic perfumery and luxury skincare not as simple aesthetics, but as daily rituals that act, in a measurable way, on emotional well-being. In this article, we'll explore why — supported by scientific literature, not just intuition.

The Power of Olfactory Memory

Among all the senses, olfaction holds a unique position in the architecture of the human brain — and it's a structural difference, not just a figure of speech.

A direct shortcut to emotions

When you see something or hear a sound, the sensory signal stops in the thalamus — a sort of switchboard that sorts information — before reaching the brain areas linked to memory and emotion. Not so with smell. Signals originating from the olfactory bulb, the structure just above the nasal cavity, reach two crucial regions almost directly: the amygdala, which generates and processes emotions, and the hippocampus, which forms and organizes memories. This direct anatomical connection — documented in both recent neuroimaging studies and comparative anatomy literature — is unique among all sensory systems, and it's why odors arrive "laden" with emotion even before you've consciously recognized them.

Researchers at Harvard Medicine Magazine describe this circuit as a pathway that, if the hippocampus deems an odor linked to an emotionally significant moment, can store that information indefinitely: even decades later, the same scent can suddenly resurface the memory and emotion of the original instant. It is the scientific explanation for the so-called "Proust phenomenon," from the celebrated madeleine passage in Remembrance of Things Past — a literary anecdote that contemporary neuroscientific research has transformed into a measurable mechanism.

Why no other sense has the same effect

Sight and hearing, passing through the thalamus, reach memory already "filtered" and mediated by cognitive processing. Olfaction, by bypassing that step, produces more involuntary, immediate memories, more intensely linked to the original emotional component. It is no coincidence that memories evoked by an odor are described in the literature as more vivid and more loaded with sensory details than memories recalled by a word or an image.

At the biological substrate level, the piriform cortex (which identifies "what the smell is"), the amygdala (which assigns it an emotional tone), and the hippocampus (which stores it as a memory) work in very rapid sequence — milliseconds — precisely because the olfactory bulb projects directly onto these structures, instead of having to pass through intermediate stations.

What it means for a fragrance worn every day

Every time you apply a fragrance, you're not simply "perfuming" your skin. You're building, day after day, an association between that specific scent and the moments you wear it: in the morning before going out, in the evening before an important occasion, the repeated gesture in front of the mirror. Over time, that fragrance stops being just a pleasant smell — it becomes a neurological anchor to a specific emotional state, recallable in an instant.

This is why, in the creation of Essenza fragrances, each olfactory note is chosen not only for its aromatic profile, but for the emotional association it can build over time: citrus and light for morning energy, woods and amber for evening contemplation. It's not marketing — it's neuroscience applied to everyday experience.

Why Repetition Reassures the Brain

If the first part explains why a scent can strike like lightning, this second part explains something seemingly opposite: why repetition — the same gesture, the same scent, the same cream, every day at the same time — produces a profound calming effect, not boredom.

The mere-exposure effect: familiarity as a signal of safety

In 1968, social psychologist Robert Zajonc published one of the most replicated findings in the history of experimental psychology: repeated mere exposure to a stimulus — a word, a sound, an object, even meaningless symbols — is sufficient, on its own, to increase liking for that stimulus. Zajonc called it the "mere exposure effect": there's no need to understand why something is liked; simply encountering it multiple times is enough.

The explanation that subsequent research has consolidated is as simple as it is powerful: the human brain is programmed to treat the unknown with caution and the familiar as "all clear," an implicit signal of safety. The more recognizable a stimulus becomes, the less it requires the brain to perform vigilance and evaluation — and this reduction in cognitive effort is perceived, literally, as a pleasant sensation. Familiar is fluent, fluent is easy, easy is safe, safe is pleasant: this is the logical chain at the heart of the effect.

Not just perception: also physiology

Studies subsequent to Zajonc have shown that the mere-exposure effect is significantly reduced in the presence of anxiety — whether it is a transient state or a stable personality trait. In other words: when the nervous system is already on alert, familiarity struggles to produce its normal calming effect. This suggests a direct link between the degree of activation of the brain's alarm system and the ability of repetition to generate comfort — repetition acts as a natural "antidote" precisely when the brain needs it most, provided that the state of alert is not already too high.

Rituals, according to Harvard behavioral science

Behavioral psychologists Francesca Gino and Michael Norton, from Harvard Business School, have dedicated years of experimental research to a seemingly simple topic: why do humans, when faced with uncertainty or loss, instinctively rely on rituals — sequences of symbolic, repeated actions, which in themselves lack direct practical function.

In a study published in 2014 in the Journal of Experimental Psychology: General, Norton and Gino demonstrated that people who perform a ritual after experiencing a loss — whether it's a loved one, a relationship, or even a missed opportunity — report significantly lower levels of grief compared to those who do not. The psychological mechanism identified by the researchers is the renewed sense of control: the repeated and predictable ritual restores a sense of mastery over the situation to the brain, even when the situation itself remains beyond one's control.

A second line of research by the same group, conducted with Alison Wood Brooks and other colleagues, showed that performing a ritual before a task that generates performance anxiety — public speaking, an interview, a performance — reduces anxiety measured both physiologically and subjectively, and improves subsequent performance. The interesting fact: the effect is observed even in those who explicitly state they do not believe in the effectiveness of rituals. You don't have to believe in it for it to work — it's a mechanism that acts regardless of rational conviction.

Why a daily ritual is not "just a habit"

There is a subtle but important difference between an automatic habit — brushing your teeth without thinking — and a ritual experienced with intention, where the gesture is performed with awareness of the moment and its meaning. Research on rituals and performance anxiety has specifically defined rituals as sequences of symbolic actions, often characterized by formality and repetition, distinguished from purely automatic actions precisely by their symbolic and intentional component. It is this component — the attention given to the gesture, not just its mechanical repetition — that makes the difference between "a habit" and "a reassuring ritual."

Where Olfactory Memory and Repetition Meet

Taken together, these two areas of research paint a coherent and powerful picture. On the one hand, olfaction has privileged and direct access to the brain structures that generate emotion and memory — no other sense builds memories with the same immediate intensity. On the other hand, the predictable repetition of a gesture — wearing the same fragrance, applying the same cream, following the same ritual — communicates a signal of security to the brain that reduces anxious activation and increases the sense of control.

A daily olfactory ritual, therefore, does not act on just one track but on two simultaneously: it builds a powerful emotional anchor over time (olfactory memory) and, every day it is repeated, it offers the nervous system a moment of predictability and control (effect of repetition). It is the combination of these two mechanisms — not a slogan, but two distinct bodies of scientific literature that converge — that explains why an seemingly small gesture like applying a perfume or cream can have a real, measurable effect on daily emotional well-being.

Building Your Ritual, with Intention

In light of this science, an effective olfactory ritual has three precise characteristics:

• Consistency: the same fragrance or the same cream, applied at the same time of day, builds the strongest emotional anchor over time — it is repetition, not variety, that generates the calming effect.
• Intentionality: the gesture must be performed with a minimum of conscious attention — not as a distracted automatism, but as a recognized and lived moment, to activate the "ritual" component and not just "habit."
• Real sensory quality: for the emotional anchor to be strong, the olfactory experience must be authentic and distinctive — not a generic perfume, but a fragrance that carries with it a story and an identity recognizable over time.

It is precisely on these three principles that the Essenza experience is built: fragrances and creams designed to be repeated over time, not consumed on a one-off basis, with the declared aim of becoming part of a recognizable daily ritual — and, according to what science tells us, capable of truly affecting the emotional well-being of those who experience it.
