A study by Unilever scientists in collaboration with the Microbiome Innovation Centre and the Brain & Behaviour Lab at the University of Liverpool has investigated a link between the skin microbiome and mental wellbeing. The study, published in the British Journal of Dermatology, provides unique new insights that could transform the understanding of skincare and mental wellbeing, the company reports. It is the first study of its kind to uncover the role of the skin microbiome in various bodily functions.

Cutibacterium ensures well-being

The study analysed microbiome samples from different areas of the body, including the face, scalp and armpits, as well as responses from questionnaires on psychological well-being. The results showed that higher levels of the common skin bacterium Cutibacterium were associated with a better sense of well-being. In particular, a higher level of Cutibacterium on the face and in the armpits was associated with less stress. A higher level of the bacterium in the armpits also meant an improved mood. In general, an increase in the bacterium in several parts of the body was associated with positive effects on well-being.

New knowledge for holistic products

The results are of great importance as consumers are increasingly looking at beauty and wellbeing holistically, emphasised Jason Harcup, Chief R&D Officer for Beauty & Wellbeing at Unilever. Consumers are increasingly looking for products that enhance their appearance as well as their mental and emotional well-being and contribute to their health. By expanding the scientific understanding of the so-called skin-brain axis, Unilever wants to develop holistic products that enhance inner and outer well-being. Unilever claims to have one of the world's largest collections of data on the human skin microbiome, with more than 100 patents and around 30,000 samples analysed.
