Essential oils enter our bodies either through absorption through the skin, or inhalation via the nose. They are able to affect the body through several systems and pathways and create an effect much more quickly than taking a pill, which must travel to the stomach and begin to be digested before any effect can be seen.
The skin is the body’s largest organ and anything we apply to our skin is absorbed into our bloodstream. When essential oils are applied to the skin they are absorbed and travel around the body via the bloodstream. In this way they are able to deliver a range of benefits to the body’s systems and organs. Absorption is increased by massage, as this increases the circulation in that area of the body. Heat can have a similar effect, allowing better absorption of the molecules in the oil.
When we inhale essential oils through the nose, the airborne molecules of the oil interact with the olfactory organs and can interact with the brain almost immediately. Molecules inhaled through the nose or mouth can also interact with the respiratory system via the lungs.
Essential oils & the brain
One way essential oils can be very effective is through interaction with the emotional brain or limbic system. The limbic system is directly connected to the parts of the brain that control heart rate, blood pressure, memory, breathing, hormone balance and stress levels - which is why a smell can trigger such a powerful emotional response in us. It’s also why inhaling certain essential oils can make us feel calmer or more alert almost instantly - and why we often associate certain smells with particular memories in a way that doesn’t occur with our other senses. In many cases essential oils will enter the body both via absorption through the skin and via inhalation; this can have a compounded positive effect.
Our mission is to help create a new category at the intersection of Wellness, Beauty and Mindfulness that teaches people how to use the power of their sense of smell as a tool to direct their mindful wellbeing. The fourth pillar of the wellness offering ahead of nutrition, exercise and relax. According tot he Invivo Communications Research 2019:
Scent can be harnessed as a tool to create a state of mind on demand.
The olfactory system has a direct connection to brain structures involved in memory and emotion (hippocampus, thalamus, amygdala, frontal cortex)
Scent triggers emotion, influencing mood, behaviour and habit formation through these neural connections and associative learning (linked memories and experiences).

How Aromatherapy Supports Stress Relief & Calm
Stress affects the nervous system, sleep cycles, and mood, but aromatherapy offers a natural way to calm the mind through scent, breathing, and sensory rituals. Using therapeutic essential oils like chamomile, lavender, neroli and palmarosa, Scentered’s blends help reduce tension and support emotional wellbeing. This guide explores the science behind stress-relief aromatherapy and shares easy ways to use balms and candles to feel more grounded and balanced throughout the day.
Aromatherapy helps counterbalance this by engaging the olfactory system, the part of the brain directly linked to emotion and relaxation. To learn more about the connection between scent, mood and cortisol regulation, read our Aromatherapy & Cortisol guide. When you inhale natural essential oils such as lavender, chamomile, neroli or clary sage, signals are sent to the limbic system, encouraging the body to switch from “fight or flight” into a calmer state.This is why aromatherapy is considered a gentle yet effective way to support the nervous system, reduce anxious thoughts, and bring the mind back into balance. For many, it’s a practical alternative to screen-led relaxation techniques because scent grounds you immediately in the present moment.
