Overall, I’d say this is a decent eye primer. It’s my first clean eye primer (I usually just use concealer), so I can’t compare it to others. My experience has been that it DOES hold my shadow, and I definitely think the mineral shadows I have been using need a primer. They adhere nicely to it, and it holds pretty well. The only time I have had issues with it is if my eye waters (which they do from time to time), but I have yet to find a product that would hold up to a watery eye or tears. I’d say it’s a great product if you’re using mineral or loose shadows and want something with a little more staying power than a layer of concealer - it definitely helps them stick.
