There isn’t a whole lot of peer-reviewed research on the benefits of thermal water to the skin. Most of the studies that are available are conducted by the research teams at the companies that have thermal water products. While its important to keep in mind that this may present some bias in the types of benefits each brand looks at the studies can still be evaluated. It is often hard to find independent research on ingredients that aren’t widely used across the industry.

Khadija S, Osman A, Rashid AA, Talal AH, Clark ID (2017) Strontium isotopes as a tool for estimation of groundwater recharge and aquifer connectivity. Groundw Sustain Dev 4:1-11 There are a handful of peer-reviewed studies that show that thermal waters have beneficial effects. Unfortunately, almost all of them are performed by the companies themselves, and naturally they show that their product is better than the others, so they should be taken with a grain of salt. (It’s kind of unavoidable though – independent scientists aren’t going to get funding for studying water when there’s cancer to be cured and climate change to undo.) The two best-studied thermal waters are Avène and La Roche-Posay. While this doesn’t necessarily mean that their products are better, it does mean that their effects are more substantiated, for now. There are a few studies that support this claim. In a study conducted by La Roche-Posay, thermal water reduced the irritation caused by sodium lauryl sulfate on the skin, a known irritant. a b "Water Facts| Takhini Hot Springs Yukon Canada".

The goods news is that you don’t need to visit a hot spring to benefit from the properties of thermal spring water. Pure, clean, and full of health benefits, this water can be collected, bottled, and used as part of your skincare routine. Yes, I read what you have written in the article. I also gave this to my mom to try it and she didn’t have any issues, but I also think that my experience is not something to be dismissed (even if I am maybe one out of 10 000 people who have had this kind of reaction), so I am thinking about reporting it to the company (because of all the other people that could potentially react the same way).

Elizabeth Springs in western Queensland, Australia might have had a flow of 158liters/second in the late 19th century, but now has a flow of about 5liters/second. The related term " warm spring" is defined as a spring with water temperature less than a hot spring by many sources, although Pentecost et al. (2003) suggest that the phrase "warm spring" is not useful and should be avoided. [9] The US NOAA Geophysical Data Center defines a "warm spring" as a spring with water between 20 and 50°C (68 and 122°F). Song S, Niu Y, Su L, Xia X (2013) Tectonics of the North Qilian orogen, NW China. Gondwana Res 23:1378–1401 Recent experimental studies at hot springs support this hypothesis. They show that fatty acids self-assemble into membranous structures and encapsulate synthesized biomolecules during exposure to UV light and multiple wet-dry cycles at slightly alkaline or acidic hot springs, which would not happen at saltwater conditions as the high concentrations of ionic solutes there would inhibit the formation of membranous structures. [48] [49] [50] David Deamer and Bruce Damer note that these hypothesized prebiotic environments resemble Charles Darwin's imagined "warm little pond". [48] If life did not emerge at deep sea hydrothermal vents, rather at terrestrial pools, extraterrestrial quinones transported to the environment would generate redox reactions conducive to proton gradients. Without continuous wet-dry cycling to maintain stability of primitive proteins for membrane transport and other biological macromolecules, they would go through hydrolysis in an aquatic environment. [48] Scientists discovered a 3.48 billion year old geyserite that seemingly preserved fossilized microbial life, stromatolites, and biosignatures. [51] Researchers propose pyrophosphite to have been used by early cellular life for energy storage and it might have been a precursor to pyrophosphate. Phosphites, which are present at hot springs, would have bonded together into pyrophosphite within hot springs through wet-dry cycling. [52] Like alkaline hydrothermal vents, the Hakuba Happo hot spring goes through serpentinization, suggesting methanogenic microbial life possibly originated in similar habitats.
