What Does Thermal Water Do For Your Skin?

September 19, 2019

 

Hypothermal water provides physical and chemical changes on skin thanks to hydrostatical passing through skin, absorption and accumulation on skin. It helps various dermatologic diseases to be cured.

The most important effect of hyperthermal water on skin is that it fastens blood flow. After thermal cure, positive changes have been observed such as strong and bulky hair and shining skin. Thermal water helps people of every age by slowing down getting age thanks to biological cell structure therapy. 

 

A whole host of French skin care brands like Avène, La Roche-Posay, Uriage and Vichy sell thermal water sprays. What is it, what’s in it, what does it do and how is it different from regular water?

Thermal water comes from hot springs. The water in these hot springs come from deep in the ground, where it’s heated by geothermal activity (the Earth’s natural heat which also causes lava to be molten).

As the thermal water rises to reach the spring, it passes through rocks and soil which dissolve to add minerals to the water. The mineral content of a particular thermal water depends on where it comes from. The minerals include the ones found in your skin’s natural moisturising factor (NMF), like chlorides, sodium, potassium, calcium, and magnesium.
 

 

WHAT DOES THERMAL WATER DO FOR SKIN?


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.

A lot of the studies are also in vitro, which means they’ve put bare cells or tissues in thermal water and watched the effects. These studies are good for seeing how a product works, if it works – but they’re not so good at telling you if it works in then first place. Humans are much more complex than a handful of cells in a petri dish.

With these caveats in mind, here’s what the studies say thermal water can do:

PROTECT FROM UV DAMAGE

La Roche-Posay, Uriage and Avène thermal waters have been found to protect cells from UV-related damage in vitro. Additionally, mice treated with a cream containing La Roche-Posay developed tumours slower than control groups after UVB exposure. A La Roche-Posay thermal water cream also reduced the formation of sunburn cells in human volunteers after UVB exposure.

It’s been speculated that selenium, zinc and/or copper are responsible for this effect, since they’re important for the functioning of antioxidant enzymes naturally in the skin, which soak up the damaging free radicals produced by UV light.

DECREASE INFLAMMATION

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

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.

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.

You’d expect that a higher mineral content might work better, but interestingly, comfort, softness and suppleness are better with a lower mineral content, and irritation is lowest (it’s worth noting though, that this particular study was performed by the parent company of Avène, the lowest mineral content water).
