The Lise Watier metamorfix is really the only way to apply the loose pigments.
I just dip my brush into the metamorphix, then into the product, and apply to my eyelid.
It makes the pigment appear much more bold! It can also waterproof eyeshadows.

This stuff is great. But so is water. I bought this before I realized that water does exactly the same thing and do tend to take it with me when traveling or when I really don't want anything to move.
