Flawless complexion?

Ok, don't use powder... it's too heavy and won't give you any sort of glow. What you need is a lighter liquid foundation. You can put it onto a sponge that has some moisturizer on it already for a light and glowly look. The stuff I use (Almay Nearly Naked) is light enough already that I don't need to mix it with anything. Another thing you can do is wear a tinted moisturizer instead of a foundation. Stila makes one that is like a very thin foundation. I also believe Neutrogena makes something like that as well. They both have SPF in them, which is great for your skin.
