Raise your hand if you owned MAC Spice Lip Liner in the 1990s. Me too. I also had pencils in pink, peach, red and plum—a rainbow of colors to match whatever lipstick I was wearing. Then, around the turn of the millennium, we all stopped wearing lipstick and started swiping on gloss. Which rendered lip liner kind of obsolete—unless you wanted that ring-around-your-lips look when your gloss faded. (P.S. No one I knew wanted that look.)
