It’s almost always a good idea to use some kind of base under your eyeshadow. Some higher end shadows don’t necessarily need it, but when in doubt, use a Paint Pot! My favorite for this is MAC Paint Pot in Soft Ochre. It’s a touch lighter than my skin, so it doubles as a matte highlight if I don’t want to bother with an eyeshadow highlight. Oh, and in case you forgot where your eyelids are, I’m quite glamorously indicating where you should put this product.
