What is Vitreoscilla filiformis?
Vitreoscilla filiformis is a bacterium that appeared on Earth around 3 billion years ago. However, it wasn't until 1970 that it was identified by Biotherm in the thermal spring at Molitg-Les-Bains in France, and it is now used by other brands in the L'Oréal group.
Its name, Vitreoscilla filiformis, refers to its glass-like transparency and filamentous form. Endowed with soothing and regenerative properties, it is remarkable for the many ways in which it works. By strengthening the skin's natural defences, it helps to maintain its integrity and preserve its balance.
The active ingredient is found under the name 'VITREOSCILLA FERMENT' in our products and is most often combined with other active ingredients.
Where does Vitreoscilla filiformis come from?
Vitreoscilla filiformis, or thermal plankton, is obtained by biotechnology, through a fermentation process at our Novéal plants in Tours. This manufacturing process complies with the principles of green chemistry*.
It is a biosourced and biodegradable ingredient, derived from a strain naturally present in thermal spring water.
* a process using as little energy and water as possible and generating a minimum amount of waste
What is it used for?
Vitreoscilla filiformis is used for its soothing and repairing properties for sensitive and atopic skin. By strengthening the skin's natural defences and improving its response, it promotes a soothing action and stimulates cell repair and regeneration. It also helps to rebalance the skin's homeostasis.
