I use the entire series. After washing my face, I tone my skin with a toner and then thoroughly moisturize with a lotion, and then I use this emulsion. The smooth texture spreads easily and blends in smoothly, leaving my skin feeling moisturized without being sticky, which I really like. It feels like it locks in moisture, leaving my skin feeling soft and toned. Even though my skin tends to dry out easily, the moisturizing feeling lasts until the morning, and I found it easy to use before applying makeup. I recommend this to anyone with dry skin, or anyone looking for a moisturizing yet lightweight emulsion.
