Thermal Water: What Is It And Can It Really Help Your Skin?

Is thermal water a scam or do the French know something we don’t?

Like, they go gaga over this stuff. You can’t enter a pharmacy in France without bumping into shelves stocked to the brim with all kinds of fancy water.

To the rest of the us, thermal water looks like plain old water in a pretty bottle (and a high price tag)… Does it really do anything for your skin?

Yes. As it turns out, it IS a godsend for sensitive, irritated skin. Here’s what the science says:

What The Heck Is Thermal Water?

Thermal water is water that comes from hot springs. It’s born deep into the ground where geothermal activity (i.e. the Earth’s natural heat) keeps it warm.

As the water rises to the top, it flows through soils and rocks, eroding them. It’s this erosion that fills the water with minerals, like sodium, calcium and magnesium. They go from the soil straight into the water.

That’s why no two mineral waters are alike. What minerals – and in what amounts – are in a thermal water depends on where it comes from.

For example, Avene Thermal Water has 4.8 ppm sodium, 42.7 calcium and 21.2 magnesium, while La Roche Posay Thermal Water has 10ppm sodium, 140 calcium and 4.9 magnesium.

What Does Thermal Water Do For Skin?

First thing first: most of the studies on thermal water are done by the companies themselves. And in vitro (not real skin), too. Take them with a grain of salt.

Still, the little research we have show that thermal waters have a few superpowers:

Should You Invest In A Thermal Water?

If you have sensitive skin, yes. They can help you soothe irritation, redness and all kinds of itchy diseases.

Everyone else, it depends. If you’re curious to see what they can do for you or need a little extra hydration, they may be worth a try. But they’re by no means a must have for everyone.

I use one just on hot summer days. I like to keep my skincare routine as short as possible. 😉

What Are The Best Thermal Waters?

I wouldn’t say there is a best thermal water. It just depends on what your skin likes best. But the most popular options are:

is the nitrogen used as a propellant bad for skin?

JR, no it’s not. Nitrogen gas is very unreactive and won’t cause problems for your skin.

I have a question – When do you use it? I mean, do you use it on top of makeup, after washing your face in the morning but before using skincare products, after skincare products but before sunblock, or after sunblock but before makeup? Or is that supposed to replace water when you wash your face? I’m sorry to ask what seems like a silly question but I never really understood how this product is supposed to be used.

JD, you can spray it on straight after cleansing or just use it throughout the day on top of makeup if you need a little refresh.

Thermal water completely changed my dry, sensitive skin. It’s the real deal! I use it after cleansing and to refresh my face on hot summer days. It’s also great for long flights. Spray a little on your face before you land and it’s a great way to feel more refreshed.
