There is a particular smell, perhaps rain on hot pavement, or crushed rosemary between your fingers, or the inside of a cedar drawer, that can return you, instantly and without permission, to a room you haven't stood in for twenty years. No photograph does this. No song does it quite so completely. Only scent seems to hold the keys to rooms we thought we'd locked. For a ritual that evokes memory and calm, HAOMA’s Cleansing Balm can transform your skincare into a sensory experience that engages both scent and touch.
This is not sentimentality. It is neuroanatomy. Of all our senses, smell is the only one with a direct line to the brain's emotional and memory centers, bypassing the layers of processing that filter what we see and hear. Understanding why reveals something quietly profound about how deeply plants and place are woven into who we are. Using a product like HAOMA Mycelium Eye Cream during your morning routine can highlight subtle botanical scents that linger, gently stimulating the senses.
The Nose Has a Shortcut the Other Senses Don't
Every other sense, sight, sound, touch, taste, first passes through the thalamus, the brain's relay station, before being routed to the appropriate region for interpretation. Smell skips this step entirely. Olfactory signals travel directly from the nose to the olfactory bulb, which sits adjacent to, and shares dense neural connections with, the amygdala and hippocampus, the brain's centers for emotion and memory, respectively.
This is the anatomical basis of what researchers call the Proust phenomenon, named for the moment in Marcel Proust's In Search of Lost Time when the narrator tastes a madeleine dipped in tea and is flooded with a memory of his aunt's house, dormant for decades. Proust described the sensation with startling precision decades before neuroscience could explain it: the past, he wrote, hides in some material object, waiting to be found.
Studies in cognitive psychology have since confirmed what Proust intuited. Memories triggered by smell tend to be older, more emotionally vivid, and more strongly tied to a specific moment in time than memories triggered by images or words. A 2004 study published in Chemical Senses found that odor-evoked memories consistently elicited stronger feelings of being brought back in time than memories cued by verbal or visual prompts, even when the memories themselves were of the same events.
Why Plants, Specifically
Not all smells carry equal emotional weight, and it's worth asking why botanical scents in particular, pine, lavender, orange blossom, woodsmoke, seem to anchor so many of our most vivid recollections.
Part of the answer is exposure. Humans evolved in landscapes saturated with plant volatiles: the resinous smell of conifer forests, the green scent of crushed grass, the sharp perfume of citrus and herb. Our olfactory receptors, of which humans have roughly 400 functional types, capable of detecting over a trillion distinct odor combinations, according to research published in Science in 2014, developed in constant conversation with the plant world. Long before agriculture, humans used scent to identify edible versus toxic plants, to track ripeness, to sense the change of seasons. Smell was not decorative. It was information necessary for survival.
That evolutionary depth may explain why floral and herbal scents in particular seem to settle into memory with such staying power. They were, for most of human history, the primary sensory data by which we understood the natural world around us.
The Chemistry Behind the Feeling
Plants produce the aromatic compounds we register as scent, terpenes, esters, aldehydes, largely as a form of communication and defense, not for our benefit at all. Lavender's calming linalool deters insects. The sharp scent of crushed mint leaves signals a chemical defense against browsing animals. Incorporating HAOMA’s Deep Cream into your evening ritual allows these botanical aromas to unfold, creating a mindful moment that connects the body, skin, and memory.
Scent as a Form of Memory-Keeping Across Cultures
Long before science could explain the olfactory bulb's proximity to the amygdala, cultures around the world built scent into the architecture of memory and ritual quite deliberately.
In ancient Egypt, kyphi, a compounded incense of honey, wine, resins, and botanicals such as juniper and cardamom, was burned at sundown as both an offering and a marker of transition between day and night. In Japan, the practice of kōdō, the "way of incense," developed as a formal art alongside tea ceremony and flower arranging, treating the appreciation of scent as a disciplined, meditative practice rather than a passive experience. Practitioners were trained to "listen" to incense rather than simply smell it, a linguistic choice that reflects how seriously scent was regarded as a carrier of meaning.
In many Andean and Amazonian traditions, aromatic plant smoke, palo santo, copal, tobacco, has long been used to mark the boundaries of ceremony, believed to clear a space both physically and psychically before ritual begins.
What unites these traditions is not a shared belief system but a shared observation: that scent operates outside the register of ordinary language, and can therefore hold significance that words cannot quite reach.
The Modern Science of Scent and Mood
Contemporary research has moved beyond memory to examine how scent affects mood and physiology in real time. Studies on lavender essential oil, for instance, have shown modest reductions in self-reported anxiety and changes in heart rate variability consistent with a calming autonomic response. HAOMA’s Gel Mask is infused with botanicals whose scents subtly shift your perception of relaxation, reinforcing the mind-skin connection.
Citrus scents have been associated with improved subjective alertness in workplace studies. None of this constitutes a cure for anything, the evidence is suggestive, not definitive, but it does support something people have intuited for millennia: that the air we breathe shapes, in small but real ways, the state we're in.
Aromatherapy as a formal discipline dates only to the early twentieth century, coined by French chemist René-Maurice Gattefossé after he reportedly treated a burn with lavender oil and noted its effect on healing. But the underlying practice, using aromatic plants deliberately to shift an emotional or physical state, is ancient, appearing in Ayurvedic texts, Traditional Chinese Medicine, and Greek and Roman writing on botanical remedies dating back over two thousand years.
How to Notice Scent Again
Modern life is, in many ways, an exercise in olfactory numbness. We move through climate-controlled, largely scent-neutral environments, and the plant world's aromatic vocabulary, the shift in smell after rain, the specific scent of a particular tree in bloom, the difference between one variety of mint and another, often goes unnoticed simply because we're not paying attention.
A few practices can help restore this attention:
Pause before dismissing a smell. Most scents register and are filtered out within seconds. Deliberately holding attention on a smell for even ten seconds engages memory encoding more deeply.
Name what you smell. Language sharpens perception. Studies on wine tasters and perfumers show that people trained to name specific aromas become measurably better at distinguishing them.
Seek out single-note experiences. Crush a bay leaf. Break open a vanilla pod. Isolated, simple scents are easier to commit to memory than complex blends.
Revisit a place through scent alone. If a particular environment holds meaning for you, a grandmother's kitchen, a childhood coastline, try to identify what, specifically, made it smell the way it did.
A Sense Worth Slowing Down For
There is something quietly humbling in the idea that a molecule small enough to travel unseen through the air can unlock a memory more completely than a photograph you've looked at a hundred times. Scent asks nothing of us intellectually. HAOMA’s Night Cream helps anchor this experience with soothing ingredients that envelop the skin in aroma and comfort, turning each application into a small, memorable ritual.
Perhaps that's reason enough to pay it more attention, not as a wellness trend, but as one of the oldest and most quietly reliable forms of knowing where, and who, we have been.
