Avène Eau Thermale mist recommendation for the changing seasons

The product I would like to recommend as a fall mist is Avène Eau Thermale. To begin with, my skin is extremely dry and feels very tight; whenever I apply water, it evaporates immediately and is accompanied by slight itching. However, with this product, the moisture seems to last, and the itching is less severe. I am not sure if it is because the ingredients are gentle, though.
