All you need is some regular isopropyl alcohol and something to stir it with. I used a popsicle stick.
First you crush the makeup into a fine powder. Then add alcohol to the makeup until you can get it to a smooth, spreadable consistency. Think peanut butter.
Mine looked a little clumpy in this picture, so I added a little more alcohol after I took the picture.
Then you smooth it out the best you can:
Leave it overnight or until it’s completely dry.
It isn’t as pretty as a new compact, but do I really care about that? Nope! All that crumbled makeup is usable again!
It totally worked! My shiny nose is very happy with this discovery. Now I’m off to fix a few eyeshadows that are in the same bad way. Hurray for a Pin Win!
