Where Scent Becomes a Neurobiological Signal
Why A&S Focuses on Neuro Scent Therapy
Scent is more than a sensory experience. Aroma molecules can be detected through the olfactory system and the skin, initiating biological signals that interact with the brain, nervous system and interconnected neuroendocrine, immune, autonomic and metabolic pathways.
A&S studies how selected Bio-Responsive Aroma Ingredients are sensed, processed and integrated across these regulatory systems. Through olfactory–brain and dermal–systemic pathways, scent-induced signaling may influence biological processes associated with emotion, stress adaptation, sleep, cognition, skin function and physiological balance.
By integrating Olfactory Science, Sensory Neuroscience, Exposome Research and Bio-Responsive Ingredients, A&S is developing a scientific framework for Neuro Scent Therapy—exploring how scent-based neurological and sensory modulation may support regulation, resilience and Homeostasis.
Dermal-Systemic Regulation in Neuro Scent Therapy
How Skin Sensing Connects Local Signals with Whole-Body Regulation
The skin is a sensory and biological interface. A&S studies how Bio-Responsive Aroma Ingredients interact with cutaneous
sensory, neuroendocrine, immune and metabolic pathways—and how these interconnected signals may support systemic regulation and Homeostasis.

Scent-Induced Neurophysiological Modulation in Disease
Olfactory signals are integrated within the brain and transmitted through interconnected neurobiological pathways. These signals can modulate
endocrine, autonomic, neural, immune, metabolic, circadian and gut–brain functions—linking sensory input with systemic balance and disease-related dysregulation.
