I've been using NARS sheer glow foundation in o1 Siberia lately.
I have to say, I like it.
The coverage is really great. It smooths everything out nicely without looking cakey. Somehow, it makes my skin look glowy, and I absolutely love that.
There is one major let down about sheer glow. It only lasts about 8 hours on my skin and then it seems to disappear. I've been using MAC mineralize skin finish natural over top and that doesn't help at all.
For the heavy price tag I can't say I'd buy it again. If only it would last longer, it would be perfect.
Cost: $42 USD
