Remede Translucent UV Coat (SPF 30)- It's not really a foundation, per se, but rather it adds a bit of a light tint- smoothes out the complexion (almost like the effect of a tinted moisturizer). On a good skin day, all I need is this and a bit of ysl radiant touch- it makes my skin look so dewy and radiant and feel so soft. I have layered concealer or foundation over this and it works wonderfully if you want heavy coverage.
Both Bliss and Sephora carry it online- and it comes in light, medium and dark. Here's the link to it on Bliss:
