I am usually very loyal to my Bobbi brown Foundations. I love them primarily because I look fresh and I don't actually feel the foundation on my face as i do with other foundations. the down side to that is that the skin foundation is so light weight that it really does not cover any of my hyperpigmentation, it does however make my face look radient. I have combination/oily skin but I still like to use light weight foundations because It doesn't matter how great a foundation looks, i won't go near it if I can feel it on my face. With Nars' sheer glow I get that light weight feeling with the added bonus of actually concealing my hyperpigmentation, this is where BB skin foundation FAILED majorly. It's important for me to have a foundation that will cover the majority of my hyperpigmentation, still feel lightweight while looking natural. for those thinking why not concealer I don't like concealer as i can feel it on my face and it tends to migrate anyway after a couple of hours. My skin looks awesome with sheer glow, and best of all it still looks like MY SKIN. I don't want people to see me and say "oh I love your make up", I'd much rather someone say "Wow you have really beautiful skin", that's when I know i'm doing something right. Oh i forgot to mention, Nars' sheer glow doesn't make me all oily like BB skin foundation sometimes can. I don't even have to set Nars' foundation and i still look just perfect. Me likey.
