I got a mini sample of this from Sephora. After checking out the ingredients and the smell, feel, etc, I went ahead and sprayed liberally on clean, dry skin and left it on all night. Surprisingly woke up to moist, glowing, happy skin. Finally ended up purchasing full size. Money well spent. Adding moisture to dry skin before using occlusive products such as heavy creams, oil or masks helps to seal the moisture in and achieve best results, this product does just that.
