What does your skin say about your gut?

Your skin is your largest (and some would say most important) organ in your body.


Unlike other organs, you can easily touch, see and check your skin health daily, so it’s a great indicator of what’s going on inside your body – especially your gut health.


Acne, facial redness, eczema, psoriasis, dry skin, and rosacea are all skin conditions which can have the same root cause; poor gut health and gut function.

The gut includes everything from the mouth all the way through to the anus – it’s responsible for absorbing nutrients, housing both helpful and harmful bacteria and excreting waste. Making improvements to the digestive system has been scientifically shown to improve skin health, immune function, mood, and energy levels.

We Are What We Absorb

Have you ever heard the saying “you are what you eat”? This common saying is not necessarily true… it’s much more accurate to say that “you are what you absorb.”

The primary role of the gut is to absorb the nutrients from your food that your body needs for growth, repair, and normal functioning.

There are many things that inhibit proper absorption of nutrients, and when the body doesn’t receive enough nutrients, it begins to prioritize which organs will get the few nutrients that are available.

Our hair, nails, and skin are usually the first places in which we notice changes. This is because when nutrients are in short supply, the body drives nutrients towards essential organs like the heart, brain, and liver.

The first step in healing your gut and skin is to make sure that your body is getting all of the nutrients it needs through diet, but due to pasteurization which irradiates and processes out any naturally occurring beneficial bacteria while at the same time feeding harmful bacteria with a feast of processed starches and sugars, our bodies rarely get the vital nutrients it needs.

Chewing is the only mechanical way to break down your food, but once it’s been swallowed, the body must have digestive enzymes, acids and probiotics to further break food down because there are no teeth in your stomach! Large pieces of food take much longer to break down than small well chewed pieces. We want food to be absorbed as quickly as possible to ensure that it doesn’t sit in the gut and ferment, which can then cause unpleasant gas and bloating… Something we all want to avoid!

Another important part of the early digestion process is your stomach’s acid and digestive enzymes. Both of these substances help to break food down into small molecules that your body can then absorb.

Many people don’t make enough stomach acid, and symptoms include; reflux, bloating, gas, and facial redness. A lack of digestive enzymes can reduce the amount of fat and protein that you absorb, and leave your skin feeling dry and dull – which can be the cause of eczema and psoriasis.

The Good Bugs

Gut bacteria have a massive influence on the health of your body, and especially the health of your skin.

Ideally, you want to have 85% good bacteria to about 15% bad bacteria. This is an ideal ratio to keep the gut healthy and functioning optimally. It’s when this ratio changes that problems can start to arise.

Gut bacteria is responsible for the digestion of some types of carbohydrates that the human body is not equipped to digest itself. The bacteria metabolize the carbohydrates into short chain fatty acids, which the body can then use for energy. Gut bacteria also produce some B vitamins and most of the vitamin K needed by the body.

A lack of helpful gut bacteria can lead to an overgrowth of bad bacteria, and when this happens, the gut walls start to become damaged.

This is known as leaky-gut syndrome and is the culprit behind many common skin issues.

The gut wall is made up of lots of cells, and each of these cells is held together by a ‘tight-junction.’ Normally these tight-junctions are impermeable and do not let substances through, however, harmful bacteria can damage these junctions and cause gaps to form. Once the tight-junctions have been opened up, you have what is known as leaky gut syndrome.

When the junctions have gaps between them, contents of the gut are able to pass through the cell wall and into the bloodstream. Molecules of food, bacteria, and parasites are then able to pass into the bloodstream where they can trigger a host of problems throughout other parts of the body.

Many autoimmune conditions, as well as skin conditions, are triggered by leaky gut syndrome.

While harmful gut bacteria is usually the leading cause of leaky gut syndrome, alcohol, gluten, dairy, food additives, and pesticides can contribute to damaging the gut wall too.

When harmful substances make their way into the bloodstream, the body looks for the quickest way to remove them… and through the skin is often the quickest and easiest option.

The body triggers an immune reaction in response to these substances, which can cause redness, swelling, and breakouts.

Taking a high quality probiotic and eating probiotic rich foods is the best way to improve your gut bacteria ratio. Foods like kefir, sauerkraut, natural yogurt, and kombucha can all help regain a healthy gut bacteria balance.

While it’s important to provide the gut with the bacteria it needs to thrive, it’s equally important to remove the substances that are causing the damage or feeding the bad bacteria.

Gluten, alcohol, refined sugars and processed foods all contribute to gut damage and inflammation in the body and should be limited or avoided if possible to help your gut and skin heal.

Keep Things Moving

The main purpose of the lower gut is to excrete substances that the body doesn’t need anymore. Ideally, you should be using your bowels at least once per day – this ensures that waste products do not sit in the body too long.

If waste is left in the lower bowel, the body can reabsorb some of the substances that it’s trying to get rid of. These reabsorbed substances can then be excreted through the skin, which as we know can cause skin problems.

Fiber and fluids are the two things needed to keep waste moving out of the body.

There are two types of fiber; soluble and insoluble. Soluble fiber is found in foods like oats, rye, barley, flax meal, chia seeds, and some fruits and vegetables.

This type of fiber helps us to feel satisfied after eating, and has the special ability to bind to substances and slow their absorption (sugars and fats), or can bind to substances helping them to be excreted (hormones and cholesterol).

Soluble fiber is especially important when it comes to skin health, as excess levels of circulating sex hormones can contribute to skin issues like melasma and breakouts.

So you need fiber to help your body move excess hormones out of your system, and keep your skin healthy and clear!

Insoluble fiber is found in all fruit and vegetables, whole grains, and nuts and seeds. Most natural plant foods contain some insoluble fiber.

Not only does insoluble fiber act as an internal cleaner, but it also feeds the bacteria living in the large intestine. The human body can’t break down insoluble fiber by itself, so we need the good bacteria in our gut to do the job for us. As they break the fiber down, they release short chain fatty acids and some vitamins, which the body can then absorb and use.

A diet high in fiber is important for the removal of waste and unneeded hormones and to feed your helpful gut bugs and to control blood sugar levels… all of which can have a direct effect on the health of your skin.

Here are our top tips to care for your digestive health for glowing skin:

  • Chew. Your. Food!
  • Eat probiotic containing foods such as; sauerkraut, kimchi, kombucha, fermented dairy, miso soup, and supplement with pre+probiotics pixies for a healthy balance and good and bad bacteria.
  • Avoid processed foods, refined sugars, alcohol, and gluten.
  • Eating a high fiber diet, including lots of fresh fruits and vegetables, legumes, beans, nuts, and seeds, as well as supplementing with a soluble fiber drink such as repair+ l-glutmine and fiber drink mix.
  • And last but least (not exactly digestion related, but…), feed your skin with nutrient-rich skin care like Avisae’s Reflexsyons skin care to complete your beauty routine for glowing, clear skin!
