Among all Exuviance products, this one's my personal favorite. Though it's called an emulsion, it's really more of a toner. After cleansing, I gently pat it onto my face with a cotton pad two or three times. It leaves my skin feeling hydrated all day long and seems to remove any lingering dead skin cells or impurities left after washing. The scent is delightful too - it's sweet like pineapple but not overpowering or irritating.
The only downside might be that you tend to use quite a bit each time... though I suppose that could vary from person to person.
I love using this after the Exuviance cleansing gel. Once it's fully absorbed, I apply my makeup, and my skin stays beautifully hydrated throughout the day.
