Our Functional Fragrance blend has been shown to prepare you for sleep, dispel anxiety and improve restorative sleep.

Aside from smelling luxuriously inviting, our Deep Sleep Functional Fragrance interacts with the limbic system — the area of the brain associated with emotions, pleasure and calmness — when tested in an fMRI study in 2017, which indicated that the fragrance has the potential to encourage a pre-disposition towards sleep.

Studies, testing our pillow spray vs a placebo on 200 male and female panelists with mild sleep anxiety, found that using deep sleep pillow spray before bedtime helped them fall asleep faster, enjoy a deeper sleep, feel less anxious before sleep and less tired in the morning (and throughout the day).

Results from our 2014 study* showed 97% of deep sleep pillow spray users said they slept better than normal, 98% were more refreshed come morning and 100% said they’d recommend it to a friend.

Studies into the fascinating nose-brain connection have shown that your sense of smell has a direct hotline to some of the most important areas of the brain. The lining of the nose contains 50 million olfactory neurons, which receive and transmit signals and carry information directly to the limbic system in the brain. This system, consisting of the hippocampus, hypothalamus and amygdala, helps control numerous voluntary endocrine (hormonal) and visceral (instinctive) responses to the world around us - and is also a key player in our emotional health and wellbeing.This Works is one of the first brands to understand the relationship between aromas and neurological responses and have led the way in the field of neuro-cosmetics. Our independent, peer-reviewed scientific paper and large scale independent user studies have proven that specific essential oils with a unique make-up of terpenes (the aromatic building blocks of essential oils) and other molecules can help manage feelings of stress, fatigue, lack of concentration and help enhance feelings of pleasure, intimacy. ​


Our Perfect Functional Fragrance has been clinically tested using fMRI brain imaging, which indicated the fragrance activated areas of the brain associated with reward, memory and emotion*. Using this functional aroma means that taking regular time to care for your body is not only good for your mood through the physical aspect of finding time for yourself, or the ingredients that nourish, care for and protect your skin, but it is also physiologically beneficial for boosting your mood.

We conducted a pilot study that explored the potential cognitive benefits of our blend of Petitgrain, Eucalyptus, Patchouli and Frankincense. Results indicated that participants exposed to this fragrance outperformed placebo and control groups in both verbal and spatial working memory tasks.

The scent was also rated most pleasant, suggesting a link between olfactory stimulation and improved cognitive function. Alongside increasing attention and alertness, brain imaging revealed activation of regions critical to working memory and attention, such as the prefrontal cortex and anterior cingulate cortex. These findings cautiously suggest the fragrance's potential to enhance cognitive performance.
