I found this product through Paula's Choice, which mentioned the excellent formulation. I have been using it at night for several weeks, probably a bit early to evaluate the effectiveness on lines. But I am glad to have a retinol product that can be used around my eyes and it does moisturize. I would agree that the serum comes out of the pump a bit fast and I often end up with more than I need..very light touch on the pump only! Just bought a few more to ensure I don't run out. :) No scent, nice matte finish once it dries. Thanks for a great product!
