MAC 'Studio Fix Fluid' and Nars 'Sheer Glow' foundations are always being raved about. I feel like they're 2 of the most popular foundations around at the moment and after trying them both I can see why. I really didn't know which one to go for when I was trying to choose my next foundation, but now that i've tried them both I know which one will be a staple in my make up collection...
