This is a decent primer/base (at least for me).  It's slightly pink, but doesn't add as much as the etude house baby choux base.  It does however leave my make-up smooth and doesn't collect in my pores.  I'm prone to dehydrated flaking in my skin by the end of the day - while this base doesn't magically fix this the flaking is not as bad and unlike other bases I've tried as it doesn't exacerbate the issue :) I wear this under my normal foundation, and my make-up lasts about 6-8 hours with out touch-up.  It's also not too heavy in moisture or oil, so it plays nice with my make-up and sunscreen.
