Eau Thermale Jonzac®. A true soulmate for your skin

A new generation of skincare that is suitable for all skin types, even sensitive skin.

This line of skincare works in perfect osmosis with the skin and its natural defense mechanisms thanks to the innovative combination of isotonic Jonzac Spring Water, and organic and extreme tolerance* formulas that are free of any potentially harmful ingredients.


Eau Thermale Jonzac®, an « Isotonic Water »

Thanks to studies carried out by Laboratoire Léa Nature, it was demonstrated that Jonzac thermal spring water is one of the rare isotonic waters.  That means that the mineral concentration in this water is identical to that of blood plasma, which ensures a perfect balance between skin cells and their direct environment.

Skin cells are therefore naturally inclined to facilitate thermal spring water penetration, providing balanced and gentle hydration without any alteration of the intracellular structure.

The skin is once again supple and velvety.  Hypotonic thermal spring waters have low levels of minerals and therefore may cause deterioration of the skin cells, while hypertonic thermal waters present higher levels that are likely to dry the skin out.  In the case of Jonzac thermal spring water, it has a natural affinity with the skin.



A biomimetic formulation

The skin consists of layers of water and fat.

If these lamellar structures are disrupted, it can lead to poor hydration, with dry or irritated patches.

The Jonzac Biomitetic formulas imitate the layered organization of the skin, with lamellar active ingredients and moisturizers.

Thus, Jonzac  certified organic and high tolerance* skincare is extremely compatible with skin for an optimal efficiency.




Organic and extreme tolerance know-how

The skin is a living biological organism, its natural balance can be easily destabilized.

All Jonzac certified organic formulas are free of any synthetic substance that is likely to cause irritation, like the Polyethylene Glycols.

The Eau Thermale Jonzac® certified organic formulas minimize the risks of allergic reactions because of their high tolerance*.

This unique Eau Thermale Jonzac® combination offering organic and high tolerance* products is ideal for all skin typeseven the most sensitive skins.


*Formulated to minimize the risk of allergic reactions
