The gut-skin axis

Gut-Skin Axis
As a surface level organ, your skin can often act as a mirror for the state of your internal health…

A growing amount of evidence suggests that this is specifically true in regards to your gut health. Dermatological problems such as eczema, rosacea, and acne may directly correlate with gut issues and abnormal intestinal flora, such as insufficient numbers of lactobacilli and bifidobacteria or intestinal wall permeability, AKA leaky gut (1).

If you’ve tried the miracle creams and 7-step skin care routines without any luck, it might be time to focus your attention inwards and give your gut some much needed TLC.

A truly healthy gut can give your skin a look and feel that no amount of topical creams or serums can hope to replicate.

So let’s get into the details…

How do the gut and skin interact? (2)

1. Nutrients absorbed and produced in the gut have a direct effect on the skin. For example, your gut flora is responsible for producing key nutrients for skin health such as hyaluronic acid (yes, that’s the same acid that’s in your must-have creams!) and biotin.

2. The nutrients absorbed and the gut bacteria absorbing it can stimulate hormonal changes that affect the skin. Your gut bacteria plays a role in cortisol levels, oestrogen levels and more!

3. The gut microbiome affects the immune system, which in turn, can affect the skin. An imbalance in intestinal gut flora (called ‘dysbiosis’) through exposure to antibiotics, toxins or other stressors can reduce beneficial flora in the gut and skin making your risk of gut and skin issues far higher.

4. The release of metabolites in the gut microbiome has an effect on the skin.

5. Intestinal hyperpermeability, also known as leaky gut, can result in food sensitivities, as proteins from foods enter the bloodstream and cause an immune response, which causes systemic inflammation as well as inflammation in the skin.

What can you do to nurture the gut-skin axis?

Feed your good gut bacteria! Especially lactobacilli and bifidobacteria.

To encourage them to thrive, multiply and improve your gut and skin health, you need to provide them with the right fuel such as prebiotic soluble fibre which is especially abundant in plant foods. 

Some bitter plants, such as artichokes, are also very beneficial for gut health and help stimulate the liver and gallbladder function, supporting the process of digestion.

Supporting the gut-skin axis though diet

To maintain a radiant appearance, it is important to understand what foods your gut doesn’t like.

This “black list” of foods to try and avoid often includes:

  •  Low fibre, processed foods
  •  Highly sugary foods
  •  Saturated fats
  • Foods with a excessively high protein content
  • Alcohol
  • Additives (found in highly processed foods such as prepared meals, sauces, etc.)
  • Certain medications such as antibiotics and laxatives

On the flip side, the gut and gut bacteria love:

  • Soluble fibre from fruits, vegetables, legumes and whole grains
  • Bitter plants such as artichokes
  • Fermented foods and drink such as sauerkraut, kimchi or kombucha
  • Foods rich in vitamins A, B2, niacin, biotin – for healthy mucous membranes.
  • Plenty of water or unsweetened herbal tea)
  • Steam or slow cooked meals to retain maximum nutrients
  • Proper chewing and calm, mindful eating to aid digestion (say no to eating in a rush)
Supporting the gut-skin axis with supplements

According to a 2020 review of the literature published in the British Journal of Dermatology, probiotic appear to be an effective for the treatment for certain inflammatory skin diseases. (3).

Meanwhile a 2015 review published in the International Journal of Women’s Dermatology confirmed that “the use of probiotics for acne and anti-aging is clearly mounting” and that probiotics can support skin health on many levels, including skin protection (4).

Probiotics have been shown to help Atopic dermatitis, Acne vulgaris, Psoriasis vulgaris, Rosacea, Wound healing and Seborrheic dermatitis (5).

The Daily Synbiotic

Our new Daily synbiotic contains 50 billion bacteria, including Lactobacillus, Bifodobacterium and Streptococcus. As well as prebiotic fibre FOS, XOS and Inulin. Research shows that combined, pre and probiotics make a dream team for healthier skin!

Lactobacillus Rhamnosus is especially recommended for people with dry skin – to help maintain the pH balance of the skin and promote the production of lactic acid (6). Meanwhile, Bifidobacteria are known for their anti-inflammatory properties, which can be helpful to people with sensitive skin and rosacea.
