So, I have had this product for roughly four months now and I am still not sure whether or not it is working for my skin. It hasn't broken me out, which I guess is a good thing, but I haven't seen a significant difference in my skin. I will say that a little goes a long, long way! It's best to apply it in the last step of your nighttime skin care, because it is a little heavy and leaves a slight whitecast.
