Use this anytime you need to rehydrate your skin. In the summertime I keep a bottle of this mist chilled in the refrigerator. Much less expensive than the HomeHealth brand I've been buying at the natural food stores all these years. Rose water can be found in Middle Eastern/Indian markets, specialty/gourmet/natural food stores and online (the brand I use is Cortas from Lebanon). It is not expensive and a little goes a long way.
