Obviously the more expensive one has an SPF12. Is there something else that causes it to cost so much more?

Answer 1

One is a powder and one is a foundation...the powder goes over the foundation...

EDIT:

The pressed powder is the cheaper one and yes, it is the one to put over your foundation....NARS is a great brand I love their blush in "o****m"--great for all skin tones.
