Hi, new here, bear with me. I have a tricky skin type. I know what kinds of foundations work best for me, but I am now looking for a good primer to use. I have combo/oily skin(drier in the wintertime, oilier in the summer) that is also very acne prone and SENSITIVE. What would be a good primer to use? I've been in some other communities, and I thought I saw someone mention Monistat?? What in the world was that all about? Anyway, I'm open for suggestions Oh, and I'm looking for something that's under $10. Thanks, I look forward to your input!
