I have always really liked Art Deco, particularly for their eye products and I think this is one of the best eye shadow bases I have tried.
You only need to use a small amount on the lids of your eyes, because excess is not useful with this particular product. I then give it a few seconds then apply my eye shadow.
This product helps bring out the pigmentation of shadows, increases how long they wear for and prevents creasing. With this product my eye shadows always last all day and look fabulous.
Since running out of it recently, I haven't been able to find it in store, but it does appear to be online.
