MAC’s one-of-a-kind recycling program is called Back 2 MAC, often abbreviated B2M. When you purchase a product from MAC, there will be a label on the box that says BACK 2 MAC, which indicates that the container is eligible to be returned to MAC. The way the program works is this: when you have accumulated six ‘empties’ (or, empty MAC containers that once contained product) you can turn them back into MAC and receive a free lipstick of your choice. This includes limited edition lipsticks released with new collections but excludes all VIVA GLAM lipsticks (as 100% of the proceeds from VIVA GLAM go to MAC’s AIDS fund). If you live near a MAC freestanding store, you are also lucky enough to be able to trade in your 6 empties for a full-size lipglass or eyeshadow, instead of a lipstick.
