Also limited edition quads, trios, duos and palettes. You can return containers from: lipstick, eyeshadow (all kinds that come in pots), lipgloss (all kinds), blush (powder, cream, mineralize), concealer, foundation, cream color base, paintpot, fluidline, paint, mascara, pigment, powder (all of them), liquid liner, shadestick, primer (anything from the prep+prime line), lip conditioner, makeup remover, face/eye cream, face wash, cleanse off oil, brush cleanser, fix+. In some places (MAC stores not counters in the US, not in Europe as far as I know and I have no idea about the rest of the world) you can get a lipstick or a lipgloss or an eyeshadow. Actually they don’t have to be empty, if there is a product you don’t want it anymore you can “back to MAC” it.
So here how it works. You return 6 empty MAC products (not the boxes they come with) and you get a free lipstick of your choice.
Back-2-M ♺C is the company’s program that incentivizes customers to recycle MAC containers and awards them with a free make up item (mainly a lipstick) of their choice.
