like everyone else has mentioned, UDPP is a makeup gem makes my e/s more vibrant, and prevents color fading and creasing all day long. i think the packaging is adorable (who doesn't love that cute little genie bottle)... but found it rather cumbersome and ineffective in the long-run. i never felt truly comfortable with the wand since it seemed unsanitary to swipe it on my eyelids and then dip it back into the bottle and letting it sit there with whatever elements the doe fot applicator came in contact with (even with clean eyelids). then there came the problem of accessing all the product. but thanks to all the wonderful MUA'ers and youtube gurus, i was able to saw open the bottle and retrieve A LOT of hidden product (months worth) that i couldn't get to because of the packaging. i scooped out the massive amounts of product and put it into a sample jar and continued to use it. but i quickly realized that the product became drier and more tacky with every use. the e/s became less blendable, and it also started making my lids feel heavier. then came the point when it stopped working so great. i finally gave up and bought TFSI (separate review).
overall, i think this product itself is great but the packaging makes me say "next!"
