I love all Avene products and I have to say they are known for their Thermal Spring Water. This product is in a spray form. I personally use it to set my foundation (mineral) so I can acheive a dewy look without looking oily/greasy. This is also great during the hot, humid months to refresh your face during the day and I love to use it when my skin gets tight from the dry heat during the winter months. If you have sensitive skin, you will love this product as a moisturizer. It contains no irritants or harmful ingredients.
