Study by Unilever uncovers first-ever connection between skin health and psychological well-being
This discovery supports the emerging concept of the skin-brain axis, suggesting that skin bacteria may play a role in mental well-being, much like the gut microbiome.
UK – Unilever, in collaboration with the Microbiome Innovation Centre and the Brain & Behaviour Lab at the University of Liverpool, has revealed groundbreaking research highlighting a possible connection between the skin microbiome and mental wellbeing.
The study, led by Unilever scientists, is the first of its kind to explore how the skin’s microbial ecosystem may influence psychological health, offering fresh perspectives that could revolutionize both skincare approaches and mental wellness strategies.
This study provides new insights that could transform the way we understand the connection between skincare and psychological health, paving the way for innovations in holistic beauty and wellness.
The research, published in the British Journal of Dermatology, highlights the role of Cutibacterium, a beneficial skin bacterium, in reducing stress and improving mood.
Findings indicate that higher levels of Cutibacterium on the face and underarm are associated with lower stress, while increased levels on the underarm correlate with enhanced mood.
Jason Harcup, Chief R&D Officer for Beauty & Wellbeing at Unilever, stated, “The skin-brain axis refers to the fact that our skin and psychological wellbeing are connected. Research has shown that bacteria in the gut can affect psychological wellbeing, but the role of skin bacteria has been less understood, until now.”
He added, “Our results reveal that greater relative abundance of Cutibacterium is associated with enhanced well-being, reduced stress, and improved mood across various body regions, suggesting for the first time that the skin microbiome may impact mental well-being.”
By now, Unilever has amassed one of the largest human skin microbiome datasets globally, securing over 100 patents and analyzing more than 30,000 samples to advance research in skin health and wellbeing.
Meanwhile, Unilever announced plans to invest £80 million (USD 103 million) in enhancing its fragrance research and development capabilities in the UK, unveiling a state-of-the-art fragrance innovation hub in Port Sunlight, England.
This initiative aims to advance sustainable fragrance technologies, improve consumer scent experiences, and reinforce Unilever’s commitment to innovation in the global beauty and personal care market.
This strategic move aims to enhance fragrance development across Unilever’s home care, personal care and beauty & wellbeing brands, including Dove, Persil, Rexona (known as Sure in the UK), and TRESemmé.
The new facility will feature a Fragrance Research & Innovation Lab, a compounding unit for blending and refining scents, and evaluation suites where fragrances will be tested for performance and consumer appeal.
