thermal spring water

Thermal water is naturally mineralized spring water with a composition suitable for therapeutic uses. It has a series of characteristics that provide it with health-promoting properties, recognized by the French National Academy of Medicine

The origin of the water

Avène thermal water comes from a spring with deep origins resulting from very old rainfall. We now know that it has remained infiltrated in the ground for more than forty or fifty years (isotopic dosage measures with tritium).


The original point of discharge of Avène water is the Sainte-Odile spring. The historical spring was declared to be of public benefit in 1874 


  • Dry residue at 180℃: 266mg/l  

  • Rich in silicates SiO2:

  • 10.6mg/l


  • Temperature in °C: 25.6

  • pH: 7.5


We can see the effect of Avène Thermal Spring Water in the treatment of skin disorders by simply observing the changes taking place in the skin during the course of therapy:  reduced inflammation, mitigated irritation, accelerated healing.

The origin of the water

The water migrates very slowly from the depths to the surface within a geological layer of dolomite and dolomitic limestone, absorbing minerals as it moves along ascending pathways.


Aquifers occur at varying depths in underground layers that are sufficiently porous and permeable to allow the infiltrated water to be stored and to circulate. Some aquifers are very large and may contain hundreds of billions of tons of water.


Apart from what emerges naturally, the technique of extraction or boreholes is used to collect the Avène Thermal Spring Water and ensure it is not subject to any chemical or microbiological pollution from the surface.


The original point of discharge of Avène Thermal Spring Water is the Ste Odile spring. The traditional spring, declared to be of public interest in 1874, continues to impress with its abundance and the constant flow of 70,000 litres per hour. This thermal water is classified as having a low mineral content and by the presence of both calcium bicarbonate and magnesium. Its main characteristics include a significant amount silicates, a low sodium, a calcium / magnesium ratio of 2 (expressed in mg / l minerals) and a wide variety of different trace elements.



Today the benefits of treatment with Avène Thermal Spring Water have been clearly demonstrated in babies, children, adults and seniors suffering from chronic and disabling conditions such as atopic dermatitis and eczema, psoriasis, ichthyosis, as well as gingivitis and glossitis. It can also be used in post-cancer or post-radiotherapy and burn care. Dermatological investigation tests have been conducted to objectively assess the effectiveness of Avène Thermal Spring Water for the following conditions:

Atopic dermatitis and Eczema


  • Atopic dermatitis in children (from the first few months of life)
  • Persistent atopic dermatitis in teenagers and adults
  • Contact eczema, especially of professional origin and evolving towards chronicity
  • Eczémas infectieux
  • Infectious eczema
  • Eczema related to venous circulation problems affecting the lower limbs (varicose eczema).

Expected benefits

At the end of the hydrotherapy treatment

  • Disappearance of serosa, scabs and germs on the skin's surface thanks to the effect of thermal water application.
  • Reduced inflammation and itching linked to the specific properties of the water (termination of ongoing treatments).
  • Subsequently (in the following months):

  • Less frequent flareups of eczema or atopic dermatitis,
  • Reduction in the use of medication (corticosteroids),
  • Significant improvements in lifestyle (itching, insomnia).

Psoriasis treatment


At all stages and wherever psoriasis appears, During flareups, Subsequently to flareups

  • Plaque psoriasis,
  • Guttate psoriasis,
  • Generalized psoriasis,
  • Keratosis on hands and feet (thick and fissured psoriasis of the palms and soles),
  • Psoriasis of the scalp

Expected benefits

At the end of the hydrotherapy treatment

  • Complete cleaning of psoriasis lesions (underwater and filiform showers, scalp massage chairs),
  • Reduction in inflammation and gradual elimination of lesions,
  • Possible suspension of local treatments,
  • In season, possibility to combine with sun exposure under medical supervision
  • Reduced frequency of psorasis flareups,
  • Fewer constraints for application of medicine

Treatment of skin healing and

burn-related problems


  • Burn-related scarring both during the healing process and subsequently (thick skin, bridging),
  • Hypertrophic and keloid surgical scar (thickening, inflammation),
  • Atonic wounds (without tendency for spontaneous healing)
  • Follow-up to dermatological treatments (dermabrasion, laser) where optimal skin healing is desired.

Expected benefits

  • Avène Thermal Spring Water accelerates the process of skin repair.
  • The massage action (filiform showers, underwater massage) with various thermal techniques helps soften the damaged skin areas and prevent development of hypertrophic scars (in relief) and ridging of the skin.
  • Finally, thermal spring water reduces inflammation and itching, thus making it easier to wear compressive clothing.

Pruritus and prurigo treatment


  • All disorders where the primary symptom is pruritus (chronic itching),
  • Lichen,
  • Metabolic disorders
  • Psychosomatic dermatitis (stress-related),
  • Pruritus of the mucous membranes (anogenital)

Expected benefits

  • Very rapid soothing effects of Avène Thermal Spring Water under adjustable pressure
  • Healing in stripped skin areas,
  • Long-lasting remission.

Ichtyosis treatment


  • Dry skin, most often of hereditary origin, with frequent associated itching

Expected benefits

  • The effects of the treatment include the possibility of performing body wraps for lipid-replenishing and emollient benefits intended to treat ichtyosis.

Seborrheic dermatitis


  • Extensive and resistant seborrheic dermatitis

Expected benefits

  • The effects of Avène Thermal Spring Water are enhanced by favourable climatic conditions and the psychological impact of the unique setting for the treatment.
