The source of your child's skin problems could lie in their gut microbiome

Millions of young children suffer from sensitive skin & eczema. Thanks to new research within gut health, there is help to be found.

An imbalance in the gut microbiome has been shown to impact children's health in ways not previously known. Thanks to new science, we can now assess whether your child’s gut flora is likely contributing to their skin problems.

A healthy gut supports healthy skin

The skin and gut microbiomes are made up of microbes that live on your child’s skin and in their gut. Both are crucial for skin health and can influence the risk of developing eczema. A balanced microbiome helps keep the skin healthy, but when the balance is disrupted, it can:

  • Weaken the skin barrier and cause inflammation and rashes
  • Make the immune system more reactive, which increases the risk of eczema

If you’ve tried addressing your child's skin rashes or eczema with creams but it doesn't help, their gut microbiome might be the key.

Developed by scientists from Karolinska, KTH and Uppsala University

You're not alone. Our gut health test has helped many parents with their child's eczema.

Eczema is tough for both children and parents. Let Alba help you find the root cause of your child’s eczema and gain expert advice tailored to their needs.

“From scientific research, we know that gut health is linked to eczema and that eating the right food can reduce the problems for a child.”

FROM A PARENT

“Within a few weeks his eczema was completely cleared.”

"The great thing about Alba is that it’s based on science. You’re not guessing or relying on generic advice. The insights are personal, and the steps are easy to follow. We started diversifying Timo’s meals more and added yogurt, berries, and fermented foods. Within a few weeks, his eczema disappeared. Eight months later, it still hasn’t come back.”

Eczema can happen for many reasons

Genetic predisposition

Many children with eczema have a family history of eczema, asthma, or allergies.

Weakened skin barrier

A faulty skin barrier makes it harder to retain moisture and protect against irritants, leading to inflammation.

Overactive immune system

The immune system of children can overreact to common environmental triggers (like dust, pollen, or certain soaps), causing redness and itching.

Environmental triggers

hings like harsh soaps, dry air, sweating, allergens, and certain fabrics (like wool) can worsen eczema symptoms.

Gut bacteria imbalances

This can make a child more sensitive to triggers, weaken the skin barrier, and make the immune system overactive

FAQ

In children, it depends on the age. The baby's microbiome is constantly evolving from birth to adulthood, so monitoring its trajectory and development over time is even more informative than looking at only one snapshot.

From one microbiome test, you will discover:

  • Levels of friendly bacteria, promoting healthy development
  • Levels of unfriendly bacteria, as some types of bacteria are known to be unfriendly when in large share, being able to cause infections and inhibit friendly bacteria
  • Gut microbiome diversity, which is associated to health and wellbeing
  • Associations with constipation, from our clinical study in Sweden
  • Levels of bacteria promoting immune system development and associated to lower risk of allergy and eczema
  • Levels of bacteria promoting metabolic health and associated to healthy weight
  • Levels of bacteria promoting brain health and cognition
  • Most importantly, you will receive a set of personalized recommendations covering diet, environmental exposure, behavior and probiotic supplements (if needed) reviewed by our medical experts and discussed with you in a 1:1 consultation with a certified Nutrition & Health Coach. You will also receive 3 simple example recipes that promote optimal gut health.

Eczema is more than just dry skin, it is a chronic, inflammatory skin condition. It qualifies as eczema if:

  • Therash is persistent and recurring, often lasting weeks or longer.
  • It isitchy(sometimes severely).
  • It appears in typical areas, such as theface, scalp, hands, elbows, knees, or behind the ears.
  • The skin becomesinflamed, red, scaly, or cracked, sometimes oozing or crusting in severe cases.
  • It is triggered by irritants, allergens, weather changes, or stress.

A doctor can diagnose eczema based on symptoms and family history.

Food triggers vary between individuals, so it's best to track symptoms and consult a doctor if needed. But there are some general guidance:

  • What foods are typically good for eczema: Foods rich in omega-3 fatty acids (like salmon, flaxseeds), antioxidants (fruits and vegetables), and probiotic food (yogurt, fermented foods) may help support skin health and reduce inflammation.
  • What food can trigger eczema: While no food directly causes eczema, some children have food allergies (e.g., dairy, eggs, nuts, soy, wheat) that trigger or worsen flare-ups. Processed foods, high sugar intake, and artificial additives may also contribute to inflammation.

We are inhabited by 39 trillions of microorganisms that live on our skin, mouth, genitals, respiratory tract and gut. They are bacteria, fungi, viruses and parasites and they are essential for our health - in fact, we couldn’t survive without them! The gut microbiome is the collection of all of our microbes in the gut, and their DNA. It has a fundamental role in digestion, immune system health and brain health. Imbalances in the gut microbiome have been associated with most chronic diseases like obesity, diabetes, asthma, celiac disease and even cancer.

From a stool sample, we are able to collect the DNA of all gut microbes. From their DNA we can tell exactly which bacteria are present and what they are doing in your gut. We analyze bacterial DNA only, and we do not analyze your own DNA.
