The skin is our largest organ and represents our first line of defense against the outside world. Not only does it protect us from physical and environmental agents, but it also regulates hydration and the exchange of substances between the environment and the body. Simply put: it lets in what's good for us and blocks what could harm us.
But to perform this delicate function, the skin is not alone. It is aided by an invisible and powerful ally: the skin microbiome .

What is the skin microbiome?
The microbiome is the collection of billions of microorganisms – such as bacteria, fungi, and viruses – that live on our skin.
Although it may seem strange, these microorganisms are essential for the health of our skin. In fact, they help to:
- Protect it from pathogenic bacteria.
- Maintain pH balance.
- Strengthen the skin barrier.
A balanced microbiome contributes to more hydrated, radiant, and resilient skin. But when this balance is disrupted, skin can become vulnerable, red, dry, or prone to problems like eczema, acne, or infections.
What alters the microbiome?
Every day our skin is exposed to numerous stressors that can alter the composition of the microbiome.
Among the main invisible enemies of the skin we find:
- UV rays: damage cells and weaken the barrier.
- Air pollution: alters the microbial balance.
- Smoking and stress: they cause inflammation and imbalances.
- Nutritional deficiencies: They affect the skin too, not just the gut.
- Excessive cleaning or use of aggressive products: this also eliminates “friendly” bacteria along with the dirt.
As a result, the skin loses its natural protective ability and becomes more sensitive or prone to imbalances.
How can we protect our microbiome?
We can take care of it with small daily choices and mindful skincare. Here's how:
- Gentle cleansing: use cleansers with a physiological pH (around 5.5) and without aggressive sulphates, such as Warew double cleansing .
- Targeted hydration: choose creams rich in nourishing ingredients naturally present in our skin, such as ceramides, squalane or hyaluronic acid, which help strengthen the skin barrier, such as warew creams .
- Sun protection every day: UV rays are one of the main factors that attack and weaken our skin. Even in winter!
- Minimalist routine: Too many active ingredients or steps can irritate the skin and alter its microbiome. A few products are better, but effective and well-formulated, just like the few steps in Warew!
