BUY THIS! YOU NEED IT!

A must-have for shimmery, sparkling shadows! This is not an eye shadow primer, or really a base. It is to keep sparkles on or to make shimmery shadows appear "glossy": a foiled look without foiling.
Originally developed and formulated for a friend/pro artist in 2008, this unique "glue" is designed to hold the sparkliest, most shimmery eye shadows in place, minimize "fallout", and also to easily create a foiled look without foiling. Don't worry, it's easily washed off, and while keeps shadows in a water-resistant state, the product itself is water-soluble (no silicones or oils). Polymers give the stickiness, while glycerin and propylene glycol keep it wet and slick on skin long enough to apply & blend shadows.
Packaged in a lipgloss tube/doefoot wand (we found this was easiest for application and least messy), all you need is a tiny dab (we're not kidding, use the tiniest amount you can manage!) rubbed on with wand or fingertip over your usual primer. Wait several seconds, as the Epoxy should be tacky but not wet, and apply dry loose shadow with a brush. More Epoxy may be desired for very glittery products. This product also enables the shadow to be brushed on rather than patted. Fingertip shadow application does not work well with this product, and shadow is best applied dry. Wet application may work, but not with every shade/texture. Translucent in the tube, applies and dries completely clear. May make some shades appear darker, and doesn't work as well with mattes. To help prevent creasing under matte and shimmer shades, please use an actual shadow primer under this. Pixie Epoxy is safe to use under eyeliner, but not recommended for application directly on the waterline.

Its CRAZY how long my eyeshadow lasts with this on! My eyeshadow sparkles like crazy and sticks from day to night! There might be a little fading but not much! I Absolutely love this product and plan on getting several backups.
You only need a smidgen, maybe half or a third of a pea. You don't much at all! you just need a sticky base. If you use too much, it could end up bad but I only use a little and boy, does it do wonders!
