I use vitamin E concentrate oil 10,000 IU (liquid...light) over my eye creme. Soaks in a bit and not as heavy as vasoline. Concealer goes on smooth and doesn't cake. Also good for the undereye area (no oil glands) that is starting to get crepey/wrinkles.I heard that a tiny bit of vaseline beneath the concealer can help this problem, and it has done for me - just make sure to use a miniscule amount, to avoid the area becoming greasy.
Also remember to put a few dabs on the inner eye part (very tops of sides of nose), and a touch of white/creamy eye liner in the inner corner of eyes - tends to really brighten the area up a lot, too.
It's cheap, too!!!
