Very first Mac product: A tub of plain silver glitter gel, probably for body.
Yes, that's right.
I was 12, it was my 6th grade graduation. (I'm 20 now) Apparently, my idea of getting dolled up for this occasion was putting random glitter gel on my cheeks and eyes. Wow is it embarrassing to look at those pictures. I don't even think Mac carries that anymore.
My second Mac product that I actually used often and correctly was Prrr lipglass my freshman year of high school. Because I read in Seventeen magazine that Paris Hilton used it.
Yay adulthood! I definitely just made a big mental note to teach my future daughters about makeup. Early.
