I've been meaning to write a post about this for a while; I picked it up about a month ago when my Too Faced Shadow Insurance finally ran out. The NARS Smudgeproof Eyeshadow Base is priced at £18 from NARS counters or online (link)
In the past I've used Urban Decay Primer Potion and Too Faced Shadow Insurance. Personally I preferred the Shadow Insurance because I found the Primer Potion to be a bit too gloopy. Anyone with very oily lids may find that the Shadow Insurance isn't enough for them and I found that the thinner texture meant that it didn't make my eyeshadows look as vibrant.
The NARS base is a nice in-between product and I've been thoroughly enjoying using it! It makes my powder shadows look vibrant and prevents creasing (with both cream and powder shadows) for up to 10 hours on my slightly oily lids. The doe-foot applicator makes it easy to apply and prevents product being wasted (I'd always end up squeezing out too much Shadow Insurance!) I just dot a bit on my lids and blend it in with my finger. Easy peasy!
My one gripe with this product is that the lovely packaging will get a bit grubby in my make up bag. I'm also interested to see how long this little tube will last for me considering my Shadow Insurance lasted almost 18 months!
Do you have a favourite eyeshadow base?
