I use mica powder, however it's so fine that it gives off more of a pearlescent highlight rather than glitter. I'm looking for something a little more noticeable, but am worried that bigger flecks of glitter might fall off easier.
I've used PearlEx, but my MSC has been pretty wonky lately, so I couldn't tell you how well it sticks.
I was going to apply it on the under eye/cheek area for a dramatic almost rave-like makeup look. I guess I just want the glitter to look more noticeable than just a light dust with a pearl finish.
If shimmer is not giving the right look (even when sealing it with semi-gloss sealant), I can highly advise looking for flakes and such used for nails. There are flakes, foils, and regular glitter chunks you can apply with a little diluted gloss It will stick to the face just fine.
