Your clients cannot build gorgeous, healthy skin without a healthy gut...

Do you want to take your practice to the next level by understanding the crucial connection between gut health and skin health? If yes, then this masterclass is perfect for you. Our Gut-Skin Axis class is designed to provide you with comprehensive knowledge of the gut-skin axis and how it impacts your clients' skin health. You'll learn about the latest research on the microbiome and how it influences ageing. You'll also gain insight into how various dietary and lifestyle factors impact the gut-skin axis and contribute to gut dysbiosis.
Prebiotics and probiotics that act on the gut-skin axis possess many biological activities, including immunomodulatory and antioxidant activity, which can benefit skin conditions by increasing skin hydration, skin gloss, skin elasticity, and alleviating facial wrinkles

Why take this Gut-Skin Axis class?

Write your awesome label here.
 🦠 You'll understand the structure of the gut, the importance of 'tight junctions', the microbiome bacterial inhabitants, what causes dysbiosis and the difference between prebiotics and probiotics.

🦠 You'll be able to pinpoint dietary patterns that cause dysbiosis and devise dietary interventions that reverse dysbiosis, build a thriving microbiome and create healthy skin. You'll also understand what causes leaky gut and how to resolve it.

🦠  You'll learn about the skin microbiome and the three ways the skin creates and maintains the acidic environment. The main types of bacteria that live on the skin surface and about how skin microbes are kept in check with AMPs such as Cathelicidins. And what causes skin microbiome dysbiosis

If you're not already fascinated with how the gut affects skin-health, you soon will be...

Non-Starch Polysaccharides leave the small intestine intact and are fermented into Short Chain Fatty Acids (SCFAs) by the gut flora in the colon.

20% of circulating Lysine and Threonine (essential for Collagen biosynthesis) in adult humans is synthesised by the gut bacteria  

Intestinal inflammation is measure by the concentrations of a bio-marker called: Lipocalin-2 (Lcn-2) and this biomarker decreases on a plant-based diet

 During my work as a skincare formulator I noticed that so many cosmetic ingredients were foods or food extracts, I realised that the power to beautify, treat and rejuvenate the skin was in diet, nutrition and food...not skincare products
