I haven't used foundation in close to 30 years.... I would caution, though, against mineral based make up if you are over 50, as it shows every nook and cranny.
Make up is one thing I pay for. I've changed brands over the years, right now I'm using Bobbi Brown. My cousin works for them, at Bloomies, and is always happy to give me free advice. Before that, I used Paula Dorf.
However, I use Neutrogena cleanser I buy at CVS and Clinique skin/eye cream, which I buy from Amazon.
