There is a close connection between the gut microbiome and skin health. The imbalance of beneficial bacteria in the gut can worsen conditions such as acne and eczema, and studies have shown that it can even influence the risk of melanoma. Learn more about the complex relationship between the gut and the skin.
The intestinal tract is populated by approximately 100 trillion bacteria and other microorganisms that form what is known as the gut microbiome. Its role is not limited to supporting digestion. The “good” bacteria in the gut keep the immune system and brain working properly. At the same time, the gut microbiome also influences the health of the skin.
Between the gut and the skin there is a bidirectional communication known as the gut-skin axis. Although the study of this complex relationship is still in its infancy, there is growing evidence that gut health plays a critical role in maintaining skin health and vice versa.

Diseases triggered or aggravated by dysbiosis
circlecountries in recent years have highlighted a close link between the gut microbiome and skin health. The imbalance of beneficial bacteria in the gut, known as dysbiosis, has been associated with many common dermatological diseases. These include:
- acne vulgaris;
- atopic dermatitis;
- psoriasis;
- hidradenitis suppurativa;
- rosacea (cuperosis);
- dandruff and seborrheic dermatitis;
- alopecia areata.
Several mechanisms have been identified through which gut microbiome imbalance influences skin health:
Systemic inflammation
When the balance of beneficial bacteria in the gut is disrupted, pathogenic bacteria produce toxins and pro-inflammatory metabolites that enter the circulation and cause systemic inflammation. It affects the whole body, including the skin.
At the same time, the “good” bacteria in the gut produce short-chain fatty acids, such as butyrate, which have anti-inflammatory effects. Dysbiosis reduces the production of these beneficial metabolites and thus increases inflammation.
Chronic inflammation is a trigger for many skin conditions, the most common being acne, psoriasis, eczema and atopic dermatitis.
Immune system imbalance
The gut microbiome plays an essential role in regulating the immune system. Dysbiosis can cause the immune response to become overactive or underactive. An exaggerated immune response can contribute to the development of autoimmune diseases. Vitiligo and psoriasis are two autoimmune diseases associated with an overactive immune response.
On the other hand, when the immune response is insufficient, the skin can become more vulnerable to infections such as herpes, candidiasis and staph infections.
Leaky gut syndrome
Dysbiosis can compromise the integrity of the gut barrier, a layer of cells lining the gut that plays an important role in absorbing nutrients and blocking the passage of harmful substances from the gut into the body.
If it becomes leaky, the gut allows pathogenic bacteria and toxins to enter the bloodstream. Leaky gut syndrome can cause skin inflammation and is associated with conditions such as rosacea, eczema and chronic urticaria.
Gut microbiome may influence melanoma risk
Gut health may influence your risk of developing skin cancer, according to a 2023 study published in JAMA Dermatology. Its authors, a team of researchers at the University of Texas MD Anderson Cancer Center, observed that participants with melanoma had a different gut microbiome structure than the control group. Melanoma is the most aggressive form of skin cancer, which spreads quickly to other parts of the body.
The study included 228 participants, 179 of whom were diagnosed with melanoma at various stages, which allowed the researchers to track the progression of the disease and associated changes in the gut microbiome. They had significantly less beneficial bacteria compared to the 49 participants without melanoma in the control group.
People with melanoma also had a higher concentration of Fusobacterium bacteria compared to the control group. This type of bacteria is known to cause infections. Also, participants with early-stage melanoma had a more diverse microbiome than those with advanced stages.
The study established a correlation, without proving a causal relationship. Maintaining gut health won’t necessarily prevent skin cancer, but researchers reiterate the importance of maintaining a healthy balance of gut bacteria.
Previous research has identified a correlation between decreased microbial diversity and several chronic conditions, including type 2 diabetes and obesity.

Well, well, well, what do we have here? Ladies and gentlemen, sit back and put your cheese platters down because we’re about to dive into the oh-so-fascinating realm of the gut microbiome and its rather dubious relationship with our skin health. Yes, that’s right! Who knew that your insides could hold the key to how good—or bad—your complexion looks? It’s like that one friend who promises to deliver but always turns up empty-handed.
Now, let’s dig a little deeper—figuratively, of course, unless you fancy a career change to gastroenterology. Did you know there are about 100 trillion bacteria living in your gut? That’s more than the number of people who’ve watched The Office reruns (and let’s be honest, that’s a lot).
Gut-Skin Axis: The BFF You Never Knew You Needed
This ‘gut-skin axis’ we’re talking about is not a trendy new yoga pose, but rather a bidirectional communication system between your gut and your skin. Imagine it like a really awkward conversation at a party; both parties talking but not really listening, just worse because it’s happening inside you! The more we learn, the more we realize how crucial this communication is. Apparently, a happy gut means a happy skin—or as I like to say, "If your insides are a party, let’s hope they’re keeping the bar open and the snacks rolling!"
Here comes the science-y bit. The article goes on to mention something called dysbiosis. Sounds a bit like a fancy dance move, doesn’t it? Unfortunately, it’s not! Dysbiosis refers to the imbalance of good and bad bacteria in your gut, and it’s linked to a cavalcade of skin conditions. From common acne to that delightful rosacea, that gut health—or lack thereof—can result in your complexion resembling a teenage horror movie. And don’t even get me started on the immune problems—it’s like your body’s bouncer has taken a holiday and everyone’s sneaking in.
Inflammation Nation: The Guest Nobody Wants
Ah, systemic inflammation. The uninvited guest at your body’s party who wears inappropriate outfits and talks over everyone. When bad bacteria start producing toxins, it leads to inflammation—sort of like when you’re forced to confront an ex on a night out. Nobody wants it, but there it is!
And let’s talk about short-chain fatty acids. No, this is not a new diet trend; these little buddies are produced by your “good” bacteria and can help keep inflammation down. They’re basically the chill friends who encourage the others to stop fighting and just get along… but if dysbiosis sets in? They’re strangely absent, leaving you with a crowd of ruckus-raising bacteria instead.
Leaky Gut Syndrome: When Your Gut Goes Rogue
Then there’s ‘leaky gut syndrome’—a not-so-fun term that describes your gut barrier acting like a sieve. Imagine your gut lining is the bouncers at a club; if they’re slacking off, all sorts of undesirables get through. That’s when skin problems arise—like eczema and chronic urticaria—so if your gut’s throwing a bit of a tantrum, your skin might just join in the drama.
Melanoma: A Gut Feeling?
And just when you thought it couldn’t get any more complex, let’s touch on skin cancer as it relates to our old friend, the gut microbiome. A study mentioned indicates that those grappling with melanoma have a different gut setup compared to their un-melanoma’d counterparts. It’s almost as if your gut’s literally trying to scare the skin off you!
While the study merely establishes a correlation—not causation, folks!—to maintaining gut health, it does suggest that we might want to give our digestive system a little more love. Because let’s face it, no one wants to play hide and seek with skin cancer.
In conclusion, keeping a healthy gut isn’t about just snacking on kale and ferments while humming “I Will Survive.” It’s about acknowledging the strange, complex relationship between our guts and our skin. So, the next time you see a bad breakout, perhaps it’s worth considering what’s bubbling up on the inside. After all, when it comes to skin health, it pays to be a little gutsy!
What are some foods that can help maintain a balanced gut microbiome for better skin health?
D play a crucial role in keeping your gut—and by extension, your skin—happy. They help reduce inflammation and promote a healthy barrier function, both in the gut and on your skin. It’s as if your good bacteria are your party planners, ensuring everything runs smoothly and there’s enough food and drink to go around.
So, what does all this mean for you? Well, the connection between gut health and skin health suggests that maintaining a balanced microbiome can enhance your overall well-being. Take a moment and think about what you’re eating. Sure, that extra piece of cake might be tempting, but balancing your diet with fiber-rich foods, fermented goodies, and plenty of hydration could be the trick to nourishing not just your gut, but that lovely complexion you’re striving for.
while more research is necessary to establish causation definitively, the relationship between our gut bacteria and skin health is beginning to unfold more like a riveting novel than a stagnant textbook. So, the next time you consider indulging in that fast food fix, just remember—it may not only be affecting your waistline, but also how your skin glows or, dare I say, glows less. Cheers to happy guts and healthier skin! Now, if you’ll excuse me, I have some gut-friendly snacks to attend to.
