I have recently tried a water cream for the first time and I really like it. It's light but does really seem to hydrate my problematic skin. For me, the value is not feeling weighed down and oily, especially with this summer being so hot. But since water creams seem to be a new product (am I wrong on this?), I am wondering if this is a fad. Should I be stocking up on my new favorite cream, or is this here to stay?
