Your baby's skin microbiome: why it matters from the very first second

Het huidmicrobioom van je baby: waarom het vanaf de eerste seconde telt

The skin microbiome is one of the most researched topics in modern dermatology. Yet, most parents hardly know what it is. This article explains what the microbiome does, why the first 1000 days are so crucial — and why that changes everything about how you view baby care.

What is the skin microbiome?

Your baby's skin is covered with billions of microorganisms, bacteria, yeasts, and other microbes. Together, they form the skin microbiome: a living ecosystem that protects, supports, and balances the skin. It is not an enemy to be fought. It is an ally to be cherished.
This ecosystem forms the first barrier between your baby's skin and the outside world. It learns to distinguish what is safe and what is not. What can enter and what must stay out. A well-functioning microbiome strengthens the skin barrier, supports the immune system, and contributes to comfortable, resilient skin! For us, this is the new standard.

Did you know?
Baby skin is up to five times thinner than adult skin. This means that substances applied to the skin are absorbed much more strongly in proportion. So, what you apply literally matters more.

Why the first 1000 days are so crucial

At birth, your baby first comes into contact with the outside world — and thus with microorganisms. That moment marks the beginning of microbiome colonization. In the first 1000 days (from conception to approximately two years of age), the fundamental development of the skin microbiome takes place. The bacteria that establish themselves during this period determine how the skin will react to stimuli, influences, and external substances for the rest of its life.
This window is unique and not easily reversible. Research into the connection between the skin and the immune system shows that a disrupted microbiome in early childhood sends signals that extend far beyond the skin. In this phase, the skin is not just a covering but a learning organ.

A delicate ecosystem, and therefore vulnerable

In the first few months, a baby's skin does not yet have a fully developed lipid structure. The skin barrier, the protective layer of fats and proteins that holds skin cells together, is still developing. This makes the skin more permeable than an adult's and it loses moisture more quickly. Scientists call this Transepidermal Water Loss (TEWL). This term, unfortunately, goes hand-in-hand with baby skin.
This permeability has a downside: not only does moisture escape, but allergens, fine dust, and harmful substances can also enter. An intact microbiome and a strong barrier are the first line of defense against this invasion. This is precisely why it is so crucial that baby care supports the skin without disrupting the microbiome.

The Qeroha philosophy
Qeroha was specifically designed for this window. Each product is formulated to strengthen the skin barrier and respect the microbiome, not overpower it. Microbiome-friendly certified by Kind to Biome, independently tested.


What disrupts the microbiome?

The skin microbiome is a dynamic ecosystem and can change under the influence of various factors. For example, aggressive cleansing, excessive use of antibacterial substances, and changes in the skin barrier.

Therefore, it is important not to unnecessarily degrease baby skin or expose it to ingredients that have no clear function.

But nuance is important.

Water, preservatives, or fragrance are not automatically harmful to the skin microbiome. A product containing water, for example, needs a carefully formulated preservative system to prevent unwanted microbial growth in the product. Modern formulations can also use mild and carefully selected preservatives.

At Qeroha, we make a conscious different choice for our first three products. Our Bath Oil, Baby Oil, and Baby Balm are water-free and contain no fragrance or preservatives. Because these formulas contain no water, a traditional preservative system is not needed in these products.

We also choose ingredients with a clear function and pay attention to the stability of our formulas. For example, meadowfoam seed oil is naturally very oxidatively stable.

For us, therefore, microbiome-friendly does not mean simply avoiding as many ingredients as possible.

It means: formulating with respect for the skin and its natural ecosystem.

Our products are dermatologically tested on sensitive skin and ex vivo tested for microbiome-friendliness by Kind To Biome™, one of the strictest quality marks in the field of microbiome safety.

And because good science never stands still, our formulas also continue to evolve. If a future product, for example, needs water or a preservative system for safety and stability, we will re-examine the overall formula and its impact on the skin. Always independently certified microbiome-friendly.
