If you found your way to the Autoimmune Protocol because of your skin, you are not alone. Eczema and psoriasis are two of the most common reasons people go looking for a dietary approach to healing, and for a lot of them, AIP is where they land. The itching, the flares, the creams that help for a little while and then stop, the appointments where a doctor hands you a stronger prescription and calls it a day. If that sounds familiar, keep reading.
We are not going to tell you that AIP is a cure. It is not. But we are going to walk you through why so many people with chronic skin conditions are turning to this protocol, what the gut-skin connection actually means, and what people are noticing when they commit to the elimination phase.
Your Skin and Your Gut Are Talking to Each Other
This might be the most important thing to understand before anything else. Your skin does not operate in isolation. It is deeply connected to what is happening in your gut, and researchers have been studying this relationship, now commonly called the gut-skin axis, for decades.
Here is the basic picture. Your gut lining is supposed to act as a filter. When it is healthy, it allows nutrients through and keeps everything else out. But when the gut lining becomes damaged or overly permeable, a condition often referred to as leaky gut, undigested food particles and other compounds can slip through into the bloodstream. Your immune system, which is largely based in your gut, picks up on these foreign particles and mounts a response. For people with a genetic predisposition to autoimmune conditions, that immune response can show up on the skin.
A 2022 review published in the medical literature confirmed a direct relationship between the GI tract and skin health, noting that microbiome imbalances in the gut may affect the severity of psoriasis symptoms. Similar research points to the same connection for eczema. When the gut is inflamed, the skin often follows.
AIP addresses this directly. The entire premise of the protocol during the elimination phase is to remove foods that are known to irritate the gut lining, reduce systemic inflammation, and give your immune system a chance to calm down. For people whose skin conditions are rooted in or worsened by gut dysfunction, that reset can be genuinely meaningful.
What Eczema and Psoriasis Actually Are
Before we get into what people are experiencing on AIP, it helps to be clear about what these two conditions are, because they are not the same thing, even though they often get grouped together.
Eczema, also called atopic dermatitis, is a chronic inflammatory skin condition that causes dry, itchy, inflamed patches of skin. It flares and settles, often triggered by environmental factors, stress, or dietary choices. It is extremely common, affecting millions of adults and children in the United States, and it is closely tied to immune overactivation. Many people with eczema also have other signs of immune dysregulation, like seasonal allergies or asthma.
Psoriasis is an immune-mediated condition where the immune system accelerates the skin cell production cycle. Skin cells that normally take weeks to rise to the surface and shed begin doing so in days, leading to the buildup of thick, scaly patches. Plaque psoriasis accounts for the vast majority of cases and is characterized by red or discolored, silvery-scaled skin that can be painful and itchy. Like eczema, it flares in response to triggers, and for many people, diet is one of them.
Both conditions are rooted in immune dysfunction. Both have documented connections to gut health. And both are being explored within the AIP community with growing interest.
What People Are Actually Noticing
The formal clinical research on AIP specifically for eczema and psoriasis is still catching up. What we have right now is a strong body of research on AIP's effects on inflammatory bowel disease, combined with emerging work and a significant amount of anecdotal reporting from people who have tried the protocol for skin conditions.
A 2017 national survey study on psoriasis found that people with the condition reported the most symptom improvement after reducing their consumption of alcohol, gluten, and nightshades. Those are three of the most significant eliminations in the AIP protocol. People are also consistently reporting, across forums, practitioner case notes, and community spaces, that the first two to four weeks on AIP are often when they start to notice a shift in their skin. Less redness. Less itching. Fewer flares. Patches that have been present for years beginning to quiet down.
One researcher who spent nearly two decades struggling with eczema, trying every steroid cream her dermatologist could prescribe, has written publicly about her experience. It was not until she found AIP that she experienced clear skin for the first time in her adult life. She is now pursuing research specifically on the effects of an anti-inflammatory diet on gut barrier function and skin symptoms in people with eczema and psoriasis.
We want to be honest with you. AIP does not produce the same results for everyone. Some people see dramatic improvement. Others notice modest changes. Some find that reintroducing certain foods, particularly nightshades or eggs, immediately triggers a flare, while other foods come back without issue. That variability is exactly why AIP is designed the way it is. The elimination phase is not meant to be permanent. It is meant to give you clarity.
Why the Foods AIP Removes Matter for Skin
The foods eliminated during the AIP protocol are not chosen arbitrarily. They are removed because of their documented potential to irritate the gut lining, promote inflammation, or trigger immune responses. For skin conditions specifically, a few categories are worth understanding.
Gluten is one of the most discussed. For people with autoimmune skin conditions, gluten can increase intestinal permeability, which as we covered earlier is a key driver of immune overactivation that shows up in the skin. Removing it during the elimination phase lets you see whether your skin responds.
Nightshades, including tomatoes, peppers, eggplant, and potato, contain alkaloids that can affect gut permeability in sensitive individuals. Many people with psoriasis, in particular, report that nightshades are one of their most consistent dietary triggers. You would not know that without removing them first and reintroducing them intentionally.
Dairy and eggs are removed because they are two of the most common immune triggers, and both have been connected to inflammatory skin responses in sensitive individuals. Refined sugars and seed oils are removed because they feed inflammatory pathways systemically, and when your immune system is already overactive, adding fuel to that fire is the last thing your skin needs.
What AIP Asks You to Eat Instead
This is where the protocol shifts from restriction to nourishment. AIP is not just about what you take out. It is equally focused on what you put in, and the foods it emphasizes actively support skin healing.
Fatty fish like salmon and sardines provide omega-3 fatty acids, which have documented anti-inflammatory effects and have shown preliminary evidence of benefit for eczema specifically. Colorful vegetables provide antioxidants that help counteract oxidative stress. Bone broth provides collagen and the amino acid glycine, which supports gut lining repair and has a calming effect on inflammation. Fermented foods like coconut yogurt support microbial diversity in the gut, which directly influences how your immune system behaves.
When your gut is being nourished and your immune system is no longer being constantly provoked by food triggers, your skin has a real chance to settle.
Using Our Mixes to Stay Consistent
One of the hardest parts of any elimination protocol is the mental exhaustion of having to rethink every single meal. When you are also dealing with a chronic skin condition that affects your sleep, your comfort, and your confidence, that extra cognitive load can be genuinely overwhelming.
Our baking mixes exist for exactly this reason. Every mix in our line is made without grains, gluten, dairy, eggs, nightshades, refined sugars, nuts, seeds, or artificial additives. That means when you bake with our Pancake and Waffle Mix on a morning when your skin is flaring and you just want something that feels normal, you are not gambling with your progress. The ingredients are clean, the list is short, and everything in the mix belongs on an AIP-compliant food list.
Our Bread Mix, Pizza Crust Mix, and cookie line work the same way. They are designed so that you can have comfort food during the hardest weeks of the elimination phase without having to cross-reference every ingredient. We did that work for you.
What to Expect If You Try It
Give the elimination phase a real chance. Most practitioners who work with AIP and skin conditions suggest a minimum of 30 days before drawing conclusions, and many find that 60 to 90 days gives a clearer picture. Skin takes time to reflect internal changes, and the early weeks can involve some adjustment as your gut begins to shift.
Track your skin. Take photos before you start and at regular intervals. Note your sleep, your stress levels, and your symptoms. When you begin reintroducing foods, do so one at a time and watch your skin closely over the following several days. That is how you find your actual triggers, not by avoiding everything indefinitely, but by learning exactly what provokes your immune system and building a long-term eating pattern around that knowledge.
AIP is not a life sentence of restriction. It is a structured way to understand your own body. And for a lot of people carrying years of frustration with their skin, that kind of clarity is genuinely life-changing.
