I've always loved Nature Republic products so no complaints from me this time either. It's packaged very well, sealed on the outside to give you that peace of mind. Because it's an emulsion, it's thicker than a serum and more cream like. I would even go as far as saying that you can use it as an intermediary step during the winter but it should also work fine as the last step/a light lotion in the summer. In fact, it may feel too heavy in the summer to use another cream on top of this. Overall, working as expected for my skin, no major improvement, but no major reactions.
