Here is a quick picture tutorial on how to fix a broken blush (or eyeshadow, or powder) with alcohol.
I left mine to dry overnight but it was still a bit damp around the edges (as seen below), so I left it for another night. It does't look pretty, and gone is the lovely pattern that was on it but at least it's fixed! You can also use the same technique to press loose pigments, which I've done so HERE.

Have you used this technique to fix any broken makeup?
