Avene Thermal Spring Water, 300 ml

Product Information

In vitro, Uriage,La Roche-Posay and Avène water decreased the production of inflammation-causing chemicals by skin cells. A study with human volunteers found that a La Roche-Posay thermal water gel decreased irritation caused by sodium lauryl sulfate.

Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. [1] [2] Don L. Leet (1982). Physical Geology (6thed.). Englewood Cliffs, NJ: Prentice-Hall. ISBN 978-0-13-669706-0. A thermal spring is defined as a spring that brings warm or hot water to the surface. Leet states that there are two types of thermal springs; hot springs and warm springs. Note that by this definition, "thermal spring" is not synonymous with the term "hot spring".

The minerals in thermal water appear to have antioxidant properties that some studies suggest help neutralize free radicals and possibly reduce sunburn risk.

Reduce inflammation. Thermal waters have been shown to calm irritation from harsh skin treatments like retinoids and reduce skin inflammation in eczema.

Res 5:49–52 Thermal water is commonly used for a lot of conditions related to inflammation, including atopic dermatitis (eczema), psoriasis, and ichthyosis. Naegleria fowleri, an excavate amoeba, lives in warm unsalted waters worldwide and causes a fatal meningitis should the organisms enter the nose. [70] [71] [72] Alireza M, et al. (2000).

There is no universally accepted definition of a hot spring. For example, one can find the phrase hot spring defined as Muchowska, Kamila B.; Varma, Sreejith J.; Chevallot-Beroux, Elodie; Lethuillier-Karl, Lucas; Li, Guang; Moran, Joseph (October 2, 2017).
