MAC Pigments. Contrary to popular belief, makeup does expire. MAC cosmetics are no exception. The majority of cosmetics expire in one year. However, there are certain cosmetics that expire in a few short months and certain cosmetics that last a lot longer than one year. The reason cosmetics have expiration dates is because over time bacteria builds up in them and when used they can cause infections, acne, and other nasty afflictions.
You may not go through your makeup bag like you do your refrigerator, but the fact is that your favorite beauty products â like perishable foods â have a shelf-life, too. This includes your tubes of lipstick. According to âSeventeenâ magazine, most lipsticks expire after two years. Your most-used tube may go bad sooner because of the potential for spoilage. Toss unused lipstick after two years, because it probably wonât have the best texture or color.
