Holy Grail worthy! This primer is easy to apply (I pat it on with my finger), makes colours more vibrant, prevents creasing, and my eyeshadow lasts all day/night with this on. Definitely worthy of a try!

I have both Too Faced Shadow Insurance and Urban Decay Primer Potion. They are quite similar but I do prefer TFSI over UDPP just due to the packaging. The squeeze tube is really precise so you can squeeze out just the smallest bit of product if you want. TFSI is much more emollient then UDPP so it's easier to spread out. The key is that you only need a very little amount, if you apply too much then it will not be as effective.

I don't have especially oily lids, I don't wear dark or bold eyeshadow very often so I don't really experience creasing much. I rely on primer mainly for my bottom lid, because of my eye shape and oily eye/cheek area I am guaranteed to have mascara smudges in that area regardless of it being a long wearing waterproof mascara (even the, reportedly, budge-proof Last Blast in Waterproof smudged for me within an hour). I will apply the primer all along my under eye and outer corner and then powder the area. Truly has been lifesaver, I've been mascara smudge free ever since!

Too Faced Shadow Insurance is the best primer out there! I have been using it for over a year now and its my favorite. It lasts all day and keeps my make up in place where i want it. It's $18 and its absolutely worth it! I recommend this to anyone and if you haven't tried it, go and get it! You will not regret this! Most of the people using Urban Decay after trying out Too faced Shadow Insurance change to it! Its really amazing :)

My eyelids can be really oily, especially in the hotter weather, and I don't know what I'd do without this product. It really does keep your eyeshadow fresh with a 'just applied' look that lasts throughout the day.

Now, I've tried the Urban Decay Potion primer too, and it is just as good -- equal results, I think. However! That container allows for so much waste of product, and what use is a cute little bottle when you have to cut it up with a knife to access the contents when there is still over 1/3 of the primer left? Ack! Mutilated plastic becomes less than cute.

Too Faced got it right when they decided to package their Shadow Insurance in a nifty little tube.

I was getting really tired of my eyeshadow creasing all the time. I know lots of people think they have oily eyelids, but I have REALLY oily eyelids. So much so that regular shadows crease within 3-4 hours of me putting them on. Finally, I decided to try using a primer and see where that got me.

Too Faced's Shadow Insurance is pretty amazing. It lasted me 11 hours before my eyeshadow started to crease with just a thin layer of product, and one thing I definitely noticed was that it made the color of the shadow so much more vibrant than without a primer. The shadow also clung to the primer really well.

I can't compare this to Urban Decay's Primer Potion just yet. However, just judging from the packaging, I would go with the Shadow Insurance, since they're the same price and I'm lazy as heck and would rather not cut open a bottle just to reach for more product. Also, I've read other reviewers that have compared the two products and they're really about the same, except that the Primer Potion is more popular.

I HAVE tried Lancome's Ombre Perfecteur and that lasted about 8 hours before the shadow started to crease, if that comparison helps.

This product is amazing! This really IS insurance for your best looking eye shadow. It is an eyeshadow primer , applied to the eyelid before the cosmetics. The product is skin toned, and a little goes a long way. It seals and preps the eyelid to give a perfect base for either cream or powder eyeshadow.
Shadow insurance makes any eyeshadow super blendable, intensifies the color, and helps prevent flaking, creasing, blotching, or melting until you remove your makeup. It extends the coverage of your shadow, therefore you don't have to use quite as much product to get a beautiful effect.
This product is one of my absolute faves. It goes on so silky and smoothly. It makes even inexpensive eyeshadow or the most boring shades look like a million bucks. This is definitely one of my cosmetic bag MUST HAVE items!

Works great and every time I used this my eye shadow holds up for several hours without any creasing, melting or fading. I really like that it's a tube and easy to squeezing it out.

I use this every day and am surprised how long it is lasting. I squirt a bit onto my finger and it is enough for both eyes.

By habit I put a MAC paint overtop, but I have always used paints under my eyeshadows, so I don't think it is necessary.

My eyeshadow never creases and lasts all day and night. The tube is much better designed that the urban decay product.

Shadow Insurance is always my go to product when I need a good primer for my eyes. I have used UDPP and Quo Cosmetics Eye Primer but for me both pale in comparison to Shadow Insurance. I find UPDD too pink for my skin and heavy. The color of Shadow Insurance closely matches my own skin tone and gives eyeshadow long lasting staying power on my combination skin.
