I confess initially the anti aging night cream made me 'nervous'. I asked myself the first couple of nights 'Is it working?' - because it is so very light and American women have been indoctrinated to believe that heavy, thick, greasy creams are best. I've studied this enough that I know its really NOT true - but still I was concerned because I've paid a lot for high-powered products and since I'm getting older every day, I couldn't afford to 'waste' any time!!! However this morning my skin was literally flaking of - shedding - which is EXCELLENT - that means it is sloughing off the dead top layer - which means it can compete with the stronger alpha and beta hydroxides. I am impressed with how fast it adsorbs and there is no messy pillow case.
