I purchased the mini of the primer in the anti-aging formula as my lids have started to age and I found my eyeshadow slipping into my creases and fine lines on my lid throughout the day.
The packaging is adorable and although I brought the mini (which is only 5ml) it has so far lasted me 3 months (using it around twice a week). I like the wand and applicator, it is easy to use and you don't end up with too much product. The consistency is a bit odd, its quite thin but feels velvety almost like a pore filler. It doesn't have much coverage so I found it best to use over my concealer on the lids but it does create a smooth airbrushed effect. It made my eyeshadow very easy to blend on and after an 8 hour wear my makeup was still exactly where I applied it and look as if It has just been done. I will be purchasing this in the full size when the mini runs out. It is an awesome product!
I was given a sample pack of the eyeshadow primer. There were four different types but they all did basically the same thing. When was anti-aging, one was shimmery, one was basic, and one was matte. They all made my eyeshadow pop. My shadow lasted hours through BBQs and get-togethers all-summer-long last year. I really liked the shimmery one to add a little Sparkle to Flat eyeshadows. I was even able to go swimming and my eyeshadow was still on. I didn't submerge myself underwater but I was splashed a few times. The only thing is it seemed like if you left the package open for very long, the primers all seem to dry out quickly. I guess just keep them tightly capped. This is a really good primer but it's also an expensive primer so I would recommend if you can find sample sizes for sale to buy those instead of the full size.
Tips: Do not let this dry out. It does not work the same if it gets dry. It will crumble and pill.
