This is MAC Ruby Woo lipstick, famous for being a cool-toned shade. I purchased it at a department store. Since I usually find it a bit overwhelming to wear as a full lip, I tend to apply a nude lipstick as a base and then use this as an accent only on the inner part of my lips. I love it because the color is vibrant and pretty. However, it is very matte, so you need to have your lips well-exfoliated and apply it skillfully.
