I know wearing sunscreen everyday on your face is important, but it makes my face so greasy!!! I am currently using Neutrogena Ultra Sheer Dry-touch sunblock. Still leaves my face shiny. I have also tried Cetaphil facial moisturizer with SPF 50. That was worse! Any suggestions? Is there such a thing as a sunscreen that leaves a matte finish? I'm about to give up and not wear it!
