Thermal water is basically mineral water from thermal springs. If you’ve ever seen a hot spring gushing out from under ground, then you’ve seen a source of thermal water. Usually the water rises up from the deep underground basins where the geothermal and volcanic activity of the Earth heats it up. Thermal springs can differ significantly first of all in their salt composition. It is these salts dissolved in water that determine the biological activity of thermal water and the effect it has on the skin.Practically any kind of thermal water has a more or less powerful hydrating action: the saline
Practically any kind of thermal water has a more or less powerful hydrating action: the saline solution acts like a magnet retaining water in the upper skin layers. However, the moisturising effect will be more pronounced if the skin’s surface is not allowed to dry. If the evaporation is not slowed down, soon after the initial comfortable and softening sensation the skin will start feeling tight and dry which is perceived by many as a signal to spray some more water on their face. Thermal water sprayed on the skin in the open sun, at the beach for example, can make it worse: the water droplets may act like lenses enhancing the harmful impact of sun rays. All that said, using thermal water can still be good for you—just don’t appoint it your one
All that said, using thermal water can still be good for you—just don’t appoint it your one and only skin care product. Thermal water can be applied onto clean skin as a supplementary moisturising solution followed by protective or nourishing face cream that will prevent the water from evaporating. You can even mix some thermal water into your cream, as recommended by skin doctors to the patients suffering from atopic dermatitis, eczema and psoriasis. Some kinds of thermal water (Avene, for example) can reduce skin peeling and discomfort following anti-acne retinoid treatment. Another use for thermal water is sealing your makeup: just spray it lightly onto the face and finish with some loose powder.
Thermal water is not a cure-all solution, however, and not at all essential in your daily routine. Rather, it is an additional skin care product for very dry or hypersensitive skin when the usual remedies aren’t enough.Among the most popular thermal water brands, easily found in pharmacies and shops, Uriage
Among the most popular thermal water brands, easily found in pharmacies and shops, Uriage contains the largest amount of minerals and Avene, the smallest (almost 55 times less). Vichy thermal water is also highly concentrated, even though it contains two times less minerals than Uriage. La Roche-Posay water is close to Avene in its mineral composition. Uriage thermal water is very rich in calcium, magnesium, sulphur salts and selenium. It is supposed to have a pronounced anti-oxidant and anti-inflammatory action, but can also be an irritating factor for thin and sensitive skin. Avene and Vichy seem to be the most comfortable to use and both have soothing effect. La Roche-Posay’s research indicates a positive effect of thermal water reducing irritation and improving general skin health in psoriasis patients with regular use. Note that the volunteers drank thermal water during research as well. Summing it all up, it is quite clear that thermal water can be good for one’s skin.Unfortunately, it is often used incorrectly: sprayed on the skin during the day without
Unfortunately, it is often used incorrectly: sprayed on the skin during the day without cleansing it first, applied under the open sun or in air-conditioned rooms with dry air, not followed by a ‘sealing’ cream or emulsion.
Basic rules are the following:
1. Thermal water can supplement a regular skin care for dry, sensitive, inflammation-prone skin or be an addition to skin therapy for the patients with skin disorders.
2. Thermal water should be sprayed on preliminarily cleansed skin (except when you’re using it to seal in your makeup, but then the water doesn’t actually have to be thermal, regular tap water works just as well).
3. Follow thermal water with protective, moisturising or nourishing cream.
4. If you’re using thermal water on the beach, make sure to apply your sunscreen immediately after!
