Avene Thermal Spring Water, 300 ml

Product Information

Because heated water can hold more dissolved solids than cold water, the water that issues from hot springs often has a very high mineral content, containing everything from calcium to lithium and even radium. [28] The overall chemistry of hot springs varies from alkaline chloride to acid sulfate to bicarbonate to iron-rich, each of which defines an end member of a range of possible hot spring chemistries.

Hot springs are a dependable source of water that provides a rich chemical environment. This includes reduced chemical species that microorganisms can oxidize as a source of energy. About nitrogen, I also found a study that says: „The incidence of allergic asthma has risen steadily over the last 20 years and now represents a significant health and financial burden. Reasons for this rise remain unclear, but increases in ambient pollutant levels, such as the oxidant, nitrogen dioxide (NO2),3 correlate with the increased incidence of allergic sensitization, asthma, and wheeze (1, 2). NO2 is a toxic-free radical gas that is a component of air pollution (1, 3) and is also formed in the lung during inflammation (4). NO2 has been implicated in the aggravation of asthma, particularly in children (1, 5–8). We and others have demonstrated that NO2 inhalation is injurious to the lung and can augment the degree of allergic airway inflammation and prolong allergen-induced airway hyperresponsiveness in rodent models of asthma (9, 10).” Dermatological study conducted on 6,368 people with sensitive skin following a superficial dermatological procedure. Evaluation for 7 days, with an application twice a day. Application of the spray by itself or in combination with medicinal treatments and/or other cosmetic products. Hydrate skin. Some research suggests that using thermal water on skin can make it feel more soft, supple, and comfortable. The single enduring narrative that’s permeated my career as a beauty editor is an infatuation with French pharmacy products. I love how simple but effective they are, and that the focus is always on nourishment and moisture—it’s difficult to mess up your complexion when using French pharmacy products exclusively. There's the allure of living a chic French lifestyle in general as well, but I’ll save that topic for another time.The main benefit of thermal water is considered to be its soothing or calming benefits to the skin. This is why it is often recommended for inflammatory skin conditions such as eczema, psoriasis and ichthyosis.

Thermal water is commonly used for a lot of conditions related to inflammation, including atopic dermatitis (eczema), psoriasis, and ichthyosis. W. F. Ponder (2002).

[73] The highest flow rate hot spring in Japan is the Tamagawa Hot Spring in Akita Prefecture, which has a flow rate of 150 liters/second. The Tamagawa Hot Spring feeds a 3m (9.8ft) wide stream with a temperature of 98°C (208°F). van Tubergen, A (1 March 2002). "A brief history of spa therapy".

Uses: It can be used to hydrate, soothe, and refresh the skin, set makeup, or dampen the complexion in between product applications.

Neisseria gonorrhoeae was reported to have very likely been acquired from bathing in a hot spring according to one case study, with the near-body temperature, slightly acidic, isotonic, organic matter-containing waters thought to facilitate the survival of the pathogen. [76] Haraldsson IG, et al. (2014). Geothermal baths, swimming pools, and spas: Examples from Ecuador and Iceland.The explanation of this benefit may be found in the zinc, selenium, and copper minerals that are present in the thermal water. These minerals help to absorb UV light and protect the skin against free radicals.

Thermal baths have been used for medicinal purposes for hundreds of years,” says Zeichner. “Many of the natural thermal springs are rich in minerals like sulfur, which has antimicrobial and anti-inflammatory effects.” Wang ZL, Zhang J, Liu CQ (2007) Strontium isotopic compositions of dissolved and suspended loads from the main channel of the Yangtze River. Chemosphere 69(7):1081–1088. https://doi.org/10.1016/j.chemosphere.2007.04.031 A clinical trial found that Avène reduces the severity of atopic dermatitis (eczema) when added to a cream, and decreased the amount of inflammation-causing bacteria on the skin. Avene also reduced the severe peeling that’s usually a side effect of using tretinoin as an acne treatment. La Roche-Posay also managed to help 50% of a clinical trial group suffering from psoriasis, although that study involved drinking the water as well as applying it on the skin. Thermal spring water has been shown to help inflammatory conditions like eczema and rosacea,” says Zeichner.

Hot springs often host communities of microorganisms adapted to life in hot, mineral-laden water. These include thermophiles, which are a type of extremophile that thrives at high temperatures, between 45 and 80°C (113 and 176°F). [39] Further from the vent, where the water has had time to cool and precipitate part of its mineral load, conditions favor organisms adapted to less extreme conditions. This produces a succession of microbial communities as one moves away from the vent, which in some respects resembles the successive stages in the evolution of early life.
