The Uriage Thermal Water is a fine-mist spray and contains water that is enriched with trace elements and mineral salts. I heard many compare this with the Avene spray and claimed that the Avene one seemed to be more moisturizing or stays longer on the skin. However, this is due to the fact that Uriage thermal water is isotonic which means that it will be absorbed into your skin by itself without patting or rubbing it in. I have been using this more than I drink water. It keeps my skin so soft and hydrated [my office is air-conditioned] and I use it before I apply any skincare and to set my make up. Throughout the day, I use it as and when and it keeps my makeup looking so fresh. Because of its fine mist, it does not ruin your makeup at all!
