A few of mine:
Nars Sin blush. I know Orgasm is the most popular, but the beautiful berry of Sin suits my fair (NC20) skin perfectly. It has just a touch of shimmer, but not to much for an older lady like me.
MAC Sophisto lipstick. Again a berry, but not a dark one. My lips are very pigmented and I can't do the nude lip at all. I need something at least as dark as my lips. You'd think I wouldn't even need lipstick, but I look totally washed out without it. Sophisto oxidizes on me to a pinkish berry.
Do you have some special beauty products you can't live without?
