THE SKIN
MICROBIOME BALANCE

An unbalanced microbiome is due to a lack of diversity of different bacteria species/strains on the skin.
This lack of diversity is common to acne-prone skin and eczema-prone skin.
By restoring the diversity of the bacteria on the skin, the microbiome is healthier, correlating to healthier skin overall. This microbiome acts as a natural healer and protector by forming an invisible shield against external aggressors.

DISCOVER OUR PATENTED PRE-BIOTIC
INGREDIENT AQUA POSAE:

Developed to rebalance the microbiome or to repair the skin barrier function. It is currently used in our Lipikar Baume AP+M for those with atopic eczema prone skin and in our Effaclar Duo +.
At La Roche-Posay we have always pushed the boundaries of what is possible in skincare.
For nearly the past 10 years we have focused our energy on this new field of research, Microbiome Science.
It has really changed our approach to skincare.

Traditionally skincare was designed to correct the visible signs of skin conditions
But what we have learned through our studies of the microbiome is that there is this invisible ecosystem of bacteria living on your skin.
And the balance between these different species play a vital function to your health.
We could see a direct correlation:
If your micorobiome ecosystem was balanced your skin was healthier.
If unbalanced, problems would appears stronger.

So we thought, what if we could find a way to rebalance this microbiome, to get a better outcome.
Working with our laboratories on Microbiome Science to develop a new type of ingredient.

A delicate strain grown on our thermal water.
A powerful prebiotic. We call it Aqua Posae.
“You see here the original strain, stored at -80c. Grown on thermal water, and contently monitored for 24/7. We then condition it so that it can be placed in our product at the right concentration. This process is patented and totally unique.”

Once in our product the results were beyond our expectation:
The microbiome was rebalancing, and staying balanced.
Signs of skin conditions dramatically decreased, and skin stayed healthy.

At La Roche-Posay our mission is to make a better life for those with sensitive skin
We believe our Microbiome Science is the change the industry needs
And we are excited to lead it that change.

KEY INGREDIENTS
LET'S TAKE A LOOK INSIDE

AQUA POSAE
FILIFORMIS

Developed to rebalance the microbiome, and repair the skin barrier function.
Aqua posae filiformis was proven to be able to reduce of the population of bacteria leading to scratching and flares ups.

AGUA TERMAL LA ROCHE-POSAY

La Roche-Posay Thermal Spring Water has natural prebiotic properties: it rebalances the skin’s microbiome to reinforce, soothe and protect the skin.

DISCOVER
THE PROCESS

Placeholder

We have cultivated a new ingredient.

A unique bacteria strain called Viitreoscilla filiformis is cultivated in thermal spring water.
 

An unique living ingredient.

Scientists has deepen their researches and they found out that this bacteria strain has unique healing and protective properties.
 
Placeholder

The process that makes it so unique
The Viitreoscilla filiformis is cultivated and grown slowly in LRP thermal spring water and gently with 24/7 care through a process called Fermogenese.

Back of card A constant care made by experts
The Biochemists track the growth by checking all the parameters making precise daily diagnosis to adjust the care to make sure it grows properly.
Placeholder

This strain is gently defrosted and brought back to life.
The strain is incredibly fragile and must be slowly stirred in exactly the right conditions or risk of dying or losing its unique properties. 

The culture conditions are highly controlled and stabilized during all the process;
This precious strain is really sensitive , a variation of 1 or 2 degrees can have an impact on its growth. 
Placeholder

It is fed oxygen, and thermal spring water while being kept at the right pressure and pH level.
To help the strain multiply and in order to give it its unique properties.

Collect of the strain at its highest level to get the best performances
When the growth rate is at it’s highest level, the laboratories collect the strain to get its best performances. 
Placeholder

After multiplying 1000X in population this strain is ready to be added into our products
This process is fully automated to avoid external contaminations from the environment.

This powerful prebiotic is called, at this stage of the process, Aqua Posae Filiformis and it is added in our product
This ingredient helps rebalancing your skin microbiome that is needed for patients.

Aqua posae filiformis is made in France, coming through green science process, without added solvant and using only renewable ingredients. 
This process respects the environment by minimizing water and energy consumption. 

This ingredient enrich our formula This ingredient enriched our formulain one of the first eco-friendly factory in France.
Carbon neutral, 100% renewable energy, 100% wasterwater recycled, smart construction & green spaces.

When do you develop your skin microbiome?

Babies receive their first microbiome early in their development, key elements than can impact this development is whether the birth was through the cancal or by c-section.
