Maybe follizap, I have this kind of hair (black but bleached so it looks like Megan's) and actually, I found foundation + powder makes them less visible for me. Depends on the product I guess.
The problem is, hi-res digital photos show up stuff that otherwise is not or barely noticeable.
My hair was/is downy but dense and very long and the fact that it is naturally black meant I was bleaching every week. My upper lip was done in London and I've had some work done with Josefa on the beard and neck area (enough to make a big difference). Those whiskers that MF has, are no longer there for me but the smaller hairs below are still there.
When I saw Josefa, I asked if I needed more work done on my upper lip and she said it was fine. Asking around friends for opinions beforehand, they all said my upper lip looked hairless.
But if someone takes a close up shot, with a DSLR and flash, then you can see the tiny, remaining hairs. That does not mean I'd bother removing them if everyone is telling me they can't see them.
