Oily skin from exemesttane?

Silly as it sounds has anyone had an increase in facial oiliness on Exemestane? I'm 72 and my face I can wash it and 2 hrs later its like an oil slick! No change in diet, cleanser or other meds. I've been on it since February. I don't know what else it could be. Doesn't show as a side effect on anything I've read. Will ask oncologist next time. I've never used a moisturizer and have pretty wrinkle fee skin. Anyone else have this crazy issue?
