The Skin: Why External Skin Treatment Alone Is Often Not Enough

Many skin professionals still focus exclusively on what they see: the skin on the outside and external skin treatments. But that is like having a car beautifully washed with the best products… while forgetting to fill up with the right fuel, check the oil level, top up the windshield washer fluid, or inspect the brake pads. Beautiful on the outside, but it won't get you very far.
Our skin works exactly the same way!
The skin reacts to what happens on the inside — driven by our immune system, digestion, gut, acidity, hormones, lifestyle, nutrition, and above all… our microbes. Without that knowledge, you are only treating the surface, not the cause.
That is why I wrote my scientifically substantiated textbook on the skin-gut connection for health and skin professionals.Through this book, you gain very broad and in-depth insights into the functioning of the skin and the interaction and cooperation with the gut and the rest of the body, with our microbiome as the common thread.
The book contains extensive and clearly structured foundational knowledge in which all essential systems of the human body are interconnected, such as:
immune system
digestion
acidity (skin pH)
microbiome
sebum
enzymes
tight junctions
intestinal problems & leaky gut
lifestyle, nutrition
and mental (im)balance.
Many professionals do not yet know how strongly these processes control the skin — and how much impact you can achieve when you bring the inside and outside together in your skin treatment.
Do you want to understand how the skin *really* works? And how you, as a professional, can achieve better results by treating the skin as part of a larger, intelligent system? Then this book is your new foundation.
Let me know if you would like to take a look at a copy or have questions about the content.
