The connection between liver health and the skin is well-known, especially in serious liver diseases. For example, a yellowing of the skin is seen with liver cirrhosis, a condition in which scarring replaces normal functioning liver tissue. Pruritis, or skin itching, can also be associated with liver disease.
The reason? The liver is one of the major detoxification organs in the body. It filters the blood and processes, breaks down, and packages major toxins (metabolites, alcohol, caffeine, medications, hormones, environmental pollutants) that your body is exposed to, in order to either make them more usable by the body, or to eliminate them. If this “processing plant” is overburdened and starts to work more sluggishly, the toxins need to go somewhere. Often, in an attempt of the body to get rid of them, many will end up in the skin, a secondary organ of elimination, and also our largest detoxification organ. Even if you don’t have a serious liver disease, your liver enzymes may not be working as optimally as they could, with repercussions showing up elsewhere, such as your skin.
Therefore, in order to have healthy-looking skin, you want to make sure that your primary organs of detoxification are working properly.
Supporting Your Primary Organs of Detoxification
Our primary organs of detoxification include the liver, the intestines, and the kidneys.
1) Drink Enough Water
You can support kidney detoxification by drinking a sufficient amount of water, typically about 2L a day for the average person (preferably mostly away from meals to prevent diluting your digestive enzymes too much). As a rule of thumb, you should be drinking about half your body weight (in lbs) in ounces (i.e. for a 150 pound person, 150/2 = 75 oz, or roughly 9 cups). This helps you eliminate water-soluble toxins from your body, with the added bonus of plumping up your skin and decreasing the visibility of wrinkles.
2) Clean Up Your Diet
Reduce foods in your diet that will put more burden on your digestive system and on your liver. This includes processed food and sugar, alcohol, caffeine, and food sensitivities. If you’re not sure about your food sensitivities, book an appointment and I’ll run a simple lab test or help you identify them through an elimination diet. You’ll also want to include foods that help improve liver function, including leafy green vegetables, cruciferous vegetables, berries, turmeric, and sufficient protein.
3) Take Probiotics
Probiotics are essential for a healthy gut and immune system. They can be obtained from fermented foods in the diet, but this can be problematic since many people with skin conditions cannot tolerate cow’s dairy, including regular yoghurt. An alternative yoghurt, such as sheep or goat yoghurt, could be an option if they are better tolerated. However, probiotic supplements may be your best option. With supplements, we can be specific about which strains of probiotics we are using, as each strain has a slightly different effect on the immune system. For example, I use a different blend with a patient with acne versus someone suffering from an autoimmune condition such as psoriasis.
4) Drink Lemon Water
One simple addition you can try at home that gently supports liver function is starting the day with a large glass of lemon water (about 500mL of water with the juice of about ¼ of a lemon). You’ll want to wait about half an hour before having your breakfast afterwards. Again, you don’t want to dilute your digestive enzymes!
5) Use Nutraceuticals To Support Liver Detoxification
With many skin conditions, including acne and eczema, I see the fastest improvement when we include some liver supporting herbs and nutrients into the treatment plan. These can include high quality, concentrated extracts of milk thistle, dandelion, turmeric, B vitamins, and other nutraceuticals. Because these supplements can interfere with medications you are taking, or could have side-effects, work with a naturopathic doctor who can recommend the best avenue for you, monitor your progress, and modify your treatment plan if necessary. A word of caution: liver supporting herbs can initially worsen a skin condition, especially if the intestines are not working well, or if you start too much, too quickly.
Do you want healthy, glowing skin from the inside out? Then making sure that your body’s primary organs of detoxification are working to your full advantage is extremely important. I can help you identify your food sensitivities, heal your digestive system, and support proper liver detoxification through an individualized program tailored to your specific needs.
If you’ve dealt with a skin condition, such as acne or eczema, you’ve probably tried a series of different skin regimens to help improve your skin. I know what it’s like. I’ve been there, struggling with eczema, which ultimately led me to a career change from biochemical research to naturopathic medicine. You see, no matter how much I diligently used my cortisone creams and moisturizers, it kept coming back, and I knew I needed to look deeper for the answers. I found the answers were not merely skin deep. The answers were in my gut!
Naturopathic medicine has long taught that skin conditions need to be addressed through the health of the gut, and that the gut and the skin are intimately connected. When you think about it, the inside of your digestive system is like an internal continuation of your external skin. We now know that a huge part, about 80%, of your immune system lies in your gut, and that many skin conditions are associated with a dysregulation of the immune system. Your gut is your first line of defense against pathogens, and regulates your immune system’s response to different foods, toxins, and micro-organisms.
To have healthy skin from the inside out, you must first address the health of your gut! This is primarily how I address skin conditions in my practice, from the inside out, and I have seen great improvements in my patients’ skin conditions using this approach.
Skin Conditions Associated With Digestive Issues
If the link between digestive issues and skin conditions is real, we would expect to see a strong correlation between digestive diseases and skin conditions. And we do see this. For example:
-Acne rosacea, an inflammatory condition of the skin on the face, is associated with a higher prevalence of gastrointestinal complaints (including Celiac disease, Crohn’s Disease, Ulcerative Colitis, H. pylori infection, Small Intestinal Bacterial Overgrowth (SIBO), and Irritable Bowel Syndrome (IBS)) than in the general population (Egeberg et al., 2017).
-Eczema and other rashes have been associated with reactions to certain foods, including in a condition called Non-Celiac Gluten Sensitivity (Elli et al., 2015).
-Dermatitis herpetiformis is a skin condition found in ¼ of patients with Celiac disease (Kresser, 2012)
The Leaky Gut, Leaky Skin Connection
We now know that chronic inflammation and damage to the gut lining can lead to a state of intestinal hyperpermeability, where food particles and microbial toxins that shouldn’t get through do get through, leading to what we call a “leaky gut”. This damage could happen as a result of many things, including food sensitivities, genetically modified foods, an imbalance in gut flora (the microbes in the gut), infections, and chronic stress.
Many of these things worsen skin conditions as well. Stress not only impacts the gut barrier, it also makes the skin barrier more permeable, which is why you may experience a worsening of your skin condition when you are particularly stressed (Slominski, 2007). If the gut is leaky, this also influences the immunity of the skin, making it produce less protective anti-microbial peptides.
Another aspect of the gut-skin connection, which I will address in a later blog, has to do with detoxification. If the gut, a primary organ of detoxification, is compromised, then the body will try and detoxify through other means, including the secondary detoxification systems, which includes the skin.
Treating The Gut Improves The Skin
Treating skin conditions definitely requires a multi-faceted approach. However, in my practice and in my own personal experience with eczema, I have seen a tremendous improvement in skin conditions by addressing the health of the gut first and foremost. For example, including probiotics in the diet, either through fermented dairy or through probiotics, can significantly improve the severity of acne vulgaris. Treating SIBO in a patient with acne rosacea is likely to improve their rosacea symptoms. Removing gluten in the diet usually resolves dermatitis herpetiformis.
So why just stick to skin deep treatments when you can address the root cause(s) of your skin condition? Changing my diet and healing my leaky gut has been extremely important in helping me minimize my eczema. A similar approach has helped countless of my patients, and I’d love to help you too!
