Can you wear a shimmer eye shadow in your crease or does it have to be a matte?

you could wear shimmer in your crease, sure. just make sure it's shimmer as opposed to glitter. glitter i would be more cautious about since it can end up looking tacky or overdone. almost every eyeshadow out there has shimmer in it though (very very tiny shimmery pieces, not glitter, which has bigger sparkles), so don't worry about it. it's hardly noticable, all shimmer is meant to do is draw a tad bit of extra light to your eyes to make them look brighter. it's totally ok to put shimmer eyeshadow on your crease. ya know how some eyeshadows (ones with multiple colors in one pack) have a diagram on the back showing you where to put the colors? check out the color meant for your crease, most have some shimmer. don't worry. try putting some with shimmer in your crease and see how you like it.Can you wear a shimmer eye shadow in your crease or does it have to be a matte?
Yes you can. But make sure your highlight is a matte that way it toned down the shimmer on you lid.Can you wear a shimmer eye shadow in your crease or does it have to be a matte?
Makeup is all about experimenting! You need to try different things to see what works for you.
