Do you need to wear sunscreen under your mineral makeup? I wear EveryDay Minerals right now and a sunscreen underneath. With the sunscreen, by the end of the day my makeup pools to the surface making it very shiny/oily. Just wondering, since my EveryDay Mineral Makeup has Zinc and Titanium Dioxide, if this would be enough protection to wear alone. I just can't stand that thick greasy feeling at the end of the day.

Thoughts?
