This module, originally prepared for University College London, explores the intricate
communication network between the gastrointestinal system, the nervous system,
and the skin. The gut–brain–skin axis has become a central focus in understanding
the systemic drivers of aesthetic and dermatological conditions.
This module focuses on mediators of gut-brain-skin signalling pathways linked to
common skin presentations such as acne, rosacea and psoriasis. By addressing
these pathways, practitioners can move beyond symptomatic treatments to target
underlying mechanisms that contribute to both skin health and overall wellbeing.
Single Module - The Gut–Brain–Skin Connection
Practitioners will learn:
- The role of the microbiome in health – how microbial diversity influences digestive health, cognitive function, mood, and skin physiology.
- How gut dysbiosis triggers systemic inflammation, leading to metabolic and dermatological presentations.
- The gut–brain–skin axis in clinical practice – the complex interplay between dysbiosis, stress, and inflammatory pathways in conditions such as rosacea, acne, and psoriasis.
- Neuroinflammation and neuroendocrine signaling – the impact of stress, mood disorders, and HPA-axis dysregulation on skin barrier function, sensitivity, and inflammation.
- Dietary strategies for skin health – the impact of nutrition on the gut microbiome, including anti-inflammatory diets, polyphenols, and the role of fibre.
- Prebiotics and probiotics – evidence-based applications for modulating gut flora to improve skin outcomes.
- Therapeutic strategies – nutritional and integrative approaches that target the gut–brain–skin axis to enhance patient outcomes in aesthetic settings.
Key Takeaway
This module equips clinicians to recognize systemic drivers of skin concerns and to implement holistic, evidence-based interventions that support both aesthetic outcomes and patient health more broadly.
