Walk into any French pharmacy and you will see them by the register: tall aerosol cans of eau thermale from Avène, La Roche-Posay, Uriage and Vichy. French women keep one in the bathroom, one in the gym bag and one in the car. Dermatologists hand them out after procedures. But if you are new to French skincare, you might reasonably ask: is it really just expensive water in a can? Here is what thermal spring water actually is, what it can and cannot do, and how to choose the right one.
What is thermal spring water?
Thermal spring water comes from a natural underground source, protected from pollution, that emerges at the surface after filtering through rock for years — sometimes decades. On its journey it picks up a unique signature of minerals and trace elements: silica, calcium, magnesium, bicarbonates, selenium, and more. Each spring has its own composition, which is why the brands built around them all feel slightly different on the skin.
France has a long tradition of spa medicine, and several of these springs have been used in hydrotherapy centers for well over a century. Avène, La Roche-Posay and Uriage still run thermal centers in their home towns, where people with sensitive or very dry skin come for soothing water treatments. The cans in your bathroom are the take-home version: the same water, sterilized and sealed so it stays pure.
What it actually does for your skin
Thermal water is not a miracle treatment, and it does not replace a moisturizer or a sunscreen. What it does well is very specific:
- Soothes the feeling of discomfort. A cool, fine mist instantly calms skin that feels hot, tight or irritated — after shaving, a workout, a flight or too much sun.
- Refreshes and comforts sensitive skin. Because the water is gentle and free of fragrance, it is suitable even for very reactive skin, babies included.
- Helps products spread better. Misting before a serum or a sheet mask makes textures glide and absorb more evenly.
- Sets makeup. A light spray melts powder into the skin for a more natural finish.
Each brand also highlights its own spring's specificities, which is where choosing becomes interesting. One practical note for our US customers: aerosol cans can't be shipped by air, so the sprays themselves are only available to our European customers. The good news is that each brand's thermal water is the base of its skincare. So below, for every spring, we've picked a thermal-water product that ships worldwide.
Avène — the soothing specialist
Avène's water emerges in the south of France and is low in minerals and naturally rich in silicates, which gives it a very soft feel. It is the signature ingredient in every Avène formula and the reference for sensitive, reactive or easily irritated skin. To get it into your routine every day, Hydrance Rich pairs the thermal spring water with a comforting cream texture for dry, sensitive skin.

La Roche-Posay's spring is naturally rich in selenium, a trace element with antioxidant properties. The brand describes its water as soothing and softening, and it is a favorite of dermatologists for comforting skin after cosmetic procedures. Toleriane Sensitive Cream is built on this prebiotic thermal water with a minimal, fragrance-free formula — ideal for anyone using stronger actives like retinoids or exfoliating acids.

Uriage's water comes from the French Alps and is unusually rich in minerals. It is also isotonic, meaning it has the same osmotic pressure as the skin's own cells, which helps it feel comfortable and hydrating rather than drying. Uriage builds a whole hydration range around it, and the Eau Thermale Water Cream is one of its signatures: a light, fresh cream for all skin types.

Vichy's water is born in the volcanoes of Auvergne, in central France, and is rich in 15 minerals. The brand presents it as mineralizing: it helps strengthen the skin's natural barrier so it looks healthier and more resilient. Minéral 89 is the most concentrated way to use it — a daily booster made with 89% Vichy volcanic water and hyaluronic acid, applied before your moisturizer.

Eau Thermale Jonzac comes from a spa town in southwest France and focuses on high-tolerance care for sensitive skin. Its Rehydrate gel combines the thermal spring water with organic aloe vera in a fresh, cooling texture — perfect after sun, after shaving or whenever the skin feels hot and tight.

Shop nowHow to use thermal water the right way
- Spray from about 8 inches away with your eyes closed, all over the face (or press a thermal-water cream or booster into slightly damp skin).
- Wait a few seconds, then gently pat dry with a tissue. Water left to evaporate completely can leave the skin feeling tighter than before.
- Follow with your moisturizer right away to seal in comfort.
- Keep it in the fridge in summer for an extra-cooling effect.
- Use it on the go: after the gym, during a flight, on a hot day or after shaving.

Frequently asked questions
Is thermal water just water?
It is water, but not ordinary water. Each spring has a specific, stable mineral composition, and the water is collected and canned under strict conditions to keep it pure. Brands have studied their own waters for decades for their soothing and comforting effects on sensitive skin.
Can I use thermal water every day?
Yes, as often as you like. It is gentle enough for daily use on the face and body, including for babies and very sensitive skin. Just remember to pat dry and moisturize afterward.
Can thermal water replace my toner?
For many people, yes. A thermal water mist is a gentle, fragrance-free alternative to a toner, especially for sensitive skin.
