I'm a make-up snob in the sense that I'd rather not have make-up touch my face. However, at the times when I do need to (like a wedding or any special event), I stick to what works for me. I have sensitive skin and I've tried a lot of brands that make me break out --- regardless whether it's an expensive brand or not.
Nowadays, I'm trying out organic make-up. I've tried the Maybelline line and Burt's Bees tinted lip balm, and I've also tried Human Heart Nature's make-up. I think they've still got a lot to go in terms of color and how it sticks to your skin. In the meantime, I'll stick with my current brands.
