I got a sample of those at the beginning of the year, and I'm having the same dilemma. I've been pretty happy with my skin's condition lately, even though it's not perfect. I'm afraid of trying out anything new, especially since I'm starting a new job next week where image is pretty important. I'm leaning towards not using it. I feel bad throwing out perfectly fine products, but I don't think it's worth the risk- plus, I've already tried so many products that I'm completely jaded about the whole skincare industry. I'm sticking with what I know works for me.
