Ben Nye LiquiSet
This is an amazing product! It can take any powder eyeshadow and make it into a smudge proof/budge proof liquid. I use it when I want to make eyeliner out of my MAC pigments or Bare Escentals eye shadows (you could use it to foil the eye shadows too). Too Faced, Benefit and more recently Bare Escentals make similar products, but much, much more expensive (especially for how much product you get) and none of those products (I've tried them) work nearly as well as LiquiSet. A medium sized bottle of this stuff is $8.00 (a small size is $4.75....which is an equivalent size of the Bare Escental's sealer which is $18.00) and will last forever! I have put on my eyeliner at 5:00 a.m. (getting ready for work), worked all day and gone out to a concert at night and my eyeliner will be perfect when I come home. It works that well. Using this really expands your eyeliner colors. While I love my MAC Fluidline and Smashbox JetSet, the colors are limited, compared to being able to turn any eye shadow into a budge proof eyeliner.
