I'm C5/NC42 and Forcefield is too dark for me. Should suit NC45+ skin.
I apply this in sections with my fingers. I really like the coverage. It doesn't cover everything, of course, but it does cover redness & faint acne scarring/hyperpigmentation. I think that this would be great for someone with normal to slightly dry skin. Because, I have a VERY oily t-zone and even though I set it with powder and then used a setting spray, I had to blot frequently throughout the day. I wore it for at least 6 hours without a base or primer. It didn't oxidize and faded a bit, but that's probably due to my oiliness. I purchased mine from ebay (in the pump, which I don't have a problem with) and I'd consider purchasing another (in Bulletproof) if I found one at a reduced price.
