Have to agree with Serendipity. Back in the day when I was a foundation newbie this was my go-to product. Nowadays, I feel like it under performs. I usually buy two different shades of foundation and the NC 45 Studio Fix fluid is one of them. By mid-day my face is so oily the USA would probably want to invade. I've tried it with and without the primer and the effect is still the same - oily T-zone. Blotting powder works but only for a short term. The foundation also rubs off really easily! I'm not a fan of touch-ups and with my busy day I hardly have time to check my makeup often. So I'd prefer to find something a bit more long-wearing. Unfortunately I just bought a brand-new bottle of it so I'm stuck!
