Researcher-led program Hi, I am Ren Karen Fischer. For the past 24 years as a clinical nutritionist I have worked with thousands of eczema and TSW patients. In that time I have seen a lot of trends and thirty-second hacks come and go, but here is something nobody talks about: Eczema and TSW are complex disorders, and a magic cream or pill is rarely enough to create lasting skin health. Gut health matters, but it is only part of the story—eczema is a skin barrier problem too, and liver health, the microbiome and stress play their part as well. The Clear Skin Challenge addresses all of the root causes, not just the trendy one. The Clear Skin Challenge is an 8-week diet program built on science and 20 years of clinical experience with thousands of real eczema and TSW patients. It is not another skin diet built on guesswork, buzzwords (like gut microbiome) and a list of so-called gut and anti-inflammatory foods—ingredients that often make eczema and TSW worse. For 20 years I have used my original method, the Food Intolerance Diagnosis (FID) Program to help my patients achieve clear, healthy skin. The Clear Skin Challenge is a new and improved program—FID 2.0—with new science and recipes that are faster and easier to make, plus weekly online group calls so you can ask questions and stay on track. This means faster progress, with more support along the way. You will also be able to track your meals and your results as you go. You can see patient and customer results, below. Places are limited, and the current presale price ends soon.
