I have bought this as I heard many good review of it. I am using it after the first treatment essence and it is so lightweight, but moisturizing that sometimes (in the warmer days) I don't even need to follow with the emulsion or the moisturizer. It is very hydrating and doesn't break me out. It is a great product for the summer and I will definitely repurchase it in winter to see how it works in the colder climate.
