Acne is a common skin condition that plagues people of all ages from teens, to adults, as well as common outbreaks during the perimenopause and each month related to hormone balance.
Acne can cause both physical and emotional distress. While it is often believed that acne is solely influenced by external factors such as hormone imbalances or improper skincare routines, emerging research suggests a strong gut health acne connection with a growing body of evidence shedding light on how the health of our gut microbiome can directly impact the development and severity of acne.
In this blog, Epsom, Surrey based Naturopathic Nutritional Therapist and functional medicine test expert, Natalie @NatNutHC, discusses the connection between GUT health, skin and acne.

The gut microbiome is a complex ecosystem of trillions of bacteria, fungi, viruses, and other microbes that inhabit our digestive tract. These microorganisms play a vital role in maintaining our overall health, including influencing our immune system, metabolism, and even our skin health. When the balance of these microorganisms is disrupted, it can have a profound effect on various aspects of our well-being, including our skin, hormone balance and inflammation levels.
The Gut Skin Acne connection is often referred to as the gut-skin axis and refers to the bidirectional communication between the gut and the skin. Several mechanisms have been proposed to explain how an unhealthy gut can contribute to acne, and they include:
Inflammation:
An unbalanced gut can lead to chronic low-grade inflammation throughout the body. This inflammation triggers the release of various molecules that can directly affect the skin, leading to acne symptoms such as redness and inflammation. However, inflammation in itself can also cause hormone inbalance and stress to the body, which can further add to skin health issues such as acne, rosacea, psoriasis and eczema.
Leaky gut syndrome:
Also known as increased intestinal permeability, this is when the gut lining becomes damaged or starts to degrade. An abundance of certain bacteria can actually cause damage to the GUT lining, as can ultra processed foods, and inflammatory cytokines. When the GUT lining is compromised, it allows toxins, undigested food particles, and microbes to breach the GUT wall and enter the bloodstream. Effectively, toxins that were destined for the toilet leak back into your bloodstream. These harmful substances can trigger an immune response and inflammation, which can manifest as acne or other skin conditions such as rosacea, psoriasis or eczema. Effectively, the overload of toxins in the bloodstream confuses the immune system and causes it to over react driving up inflammation.

Stress and hormonal dysregulation:
The gut microbiome plays a crucial role in the production and regulation of hormones, including those that influence our stress response. Stress-induced hormone imbalances can contribute to acne and other skin breakouts such as psoriasis, eczema and rosacea. Additionally, stress can disrupt the balance of the gut microbiome, further aggravating these skin conditions. The connection between the gut and the brain is known as the gut-brain-axis and is often discussed in the literature as vagal tone, in essence the vagus nerve connects the gut and brain causing them to have a bi-directional impact on one another.
Several studies have further explored the Gut skin Acne connection, the link between gut health and acne. Research has shown that individuals with acne tend to have a less diverse microbiome compared to those with clear skin.
So, what can be done to promote a healthy gut, reduce acne and other skin breakouts including rosacea, eczema and psoriasis? Here are a few strategies:
Dietary changes:
A diet rich in fibre, antioxidants, and prebiotics foods can help nourish the gut microbiome and promote its diversity. Include plenty of fruits, vegetables, whole grains, fermented foods (such as natural yogurt and sauerkraut), and prebiotic-rich foods (such as garlic, chicory, onion, and oats) in your daily meals.
Reduce inflammatory foods:
Limiting the consumption of ultra-processed foods, refined sugars, and unhealthy fats such as ‘fake fats’ and seed oils can help reduce inflammation in the body and potentially improve acne, eczema, rosacea and psoriasis.
Manage stress:
Engage in stress-reducing activities such as yoga, meditation, regular exercise or walks in nature to promote a healthy gut brain connection and support good vagal tone.
Probiotic supplementation:
Taking specific strains of probiotics, such as Lactobacillus and Bifidobacterium, may help restore the balance of gut bacteria and potentially improve acne symptoms. However, it is essential to consult with a healthcare professional before starting any supplementation. It is also advised that a stool test is necessary before commencing any probiotic supplements, so you know exactly what strains of bacteria you need to support, otherwise you run the risk of making the GUT microbiome imbalance even worse.

Conclusion:
While more research is needed to fully understand the intricate relationship between the gut skin acne connection and the GUT-Skin Axis, the evidence suggests a significant link. In fact, the evidence to date has only just scraped the surface and there is still much to learn, but what is known so far provides us with valuable information in how best to support and reduce acne, along with other skin conditions including eczema, psoriasis and rosacea.
By nurturing a healthy gut microbiome through lifestyle and dietary changes, we can potentially improve our overall well-being and reduce the occurrence of breakouts. Remember, a holistic approach that considers both internal and external factors is crucial when addressing skin concerns, and taking care of your gut should be an integral part of that process.
