The thermal spring water of Saint-Gervais Mont Blanc

The history of a water that is beneficial for the skin
Parcours hydrogéologique

A pure and precious water

Now a rare element and of unreliable quality, water has fortunately remained intact in some places on the planet.

Miraculously protected by a preserved environment, the "Mont Blanc" thermal spring water, born in the heart of a legendary mountain is just this. The water's 60-year path through the centre of the earth has heated it. Protected from any pollution, it is extracted at an altitude of 600 m, at the foot of the Alps, at a constant temperature of 39°C, winter and summer.

It is then checked at each stage of its distribution to preserve its natural qualities and bacteriological purity.

A very rich water in minerals and micronutrients

Propriétés de l'eau thermale : pH neutre, bienfaits reconnus depuis 1806

Thermal spring water from Mont Blanc, which is highly mineralised, and classified as sulphate, chloride, sodium, calcium water and rich in trace elements, is a true "natural serum" for the skin.

Two centuries of history at the Saint-Gervais spa

The thermal source was used for the first time in 1806 as a hydrotherapeutic cure. It was very quickly recognised internationally for its dermatological benefits and its capacity to treat numerous diseases such as eczema, psoriasis and the treatment of scarring, for which the thermal spa was the initiator in France in 1959.
Given its high concentration of minerals and trace elements, as well as the right proportion of elements, the thermal spring water of Saint-Gervais Mont Blanc was praised by the National Academy of Medicine in 1996:

The physical-chemical properties of the water are suitable for dermatological spa use (due to its isotonic nature and haemostatic and healing properties), for all dermatitis and allergies of the skin and mucous membranes and scarring from burns, accidents or other origins.

It is known as being « soothing, decongestant, healing ».

An active water in perfect affinity with the skin

In addition to being soothing, decongestant and healing, the thermal spring water of Mont Blanc is naturally isotonic.
This means that it respects the integrity of cells and is in perfect osmosis with the skin.
It does not change either the size, or the volume of the cells.

We can distinguish 3 types of water :

The thermal spring water of Mont Blanc also has a strong spreading power.
Upon contact, the properties of the skin change: the naturally hydrophobic skin becomes more hydrophilic.

A true beauty serum

Sérum de beauté
  • Isotonic, in the same way as physiological serum, it respects the integrity of cells. No need to dry it.
  • Pure and pH neutral, it is suitable for all sensitive skin types.
  • Active, it modifies the skin's properties which become hydrophilic: it prepares the skin for cares and favours its application.
