When I was a young 'un in my 40's and younger, I always used Cover Girl's foundation for oily skin. Later in the day, a light pat or two of powder.
I've always used Cover Girl as a makeup foundation, Hound, so I guess I'm prejudice for liking it so much. For a woman past her (haruummph) 50th decade, I now use their powder foundation, which is light and unmasklike.
Hope you find something out there that you like
