MAC Lipglass: C-Thru

C-Thru is a milky beige with shimmer running through it. The shimmer isn't intense, very subtle. I have fairly pigmented lips and this slightly muted the color. I like to apply a thin layer of C-Thru over bright lipsticks to make them a bit more daytime wearable. Applied heavily, this is not the most flattering color on my fair skin.
