I use Prevage moisturizer 2 times per day and still have my container which was bought before Potent lift. I used only tiny amounts (Potent) and not every day, especially since the Covid-19 and used very little. My container is empty which leaves me to believe there is not 1.75 fl oz in the container. Does not work if using before makeup. I used after applying makeup with little dabs here and there. If too much applied it turned white. User's recommendation: your choice to buy. I think too expensive.
