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.
@Da215, That's a great question! Truthfully, the shelf life of your makeup will vary from product to product. Most products nowadays have an expiration date printed on the packaging, and when in doubt, it is always best to check with the manufacturer.I think itâs safe to say that most unopened makeup that doesn't list an expiration date (except for mascara and nail polish) has a shelf life of about 3 years.Unopened mascara has a shelf life of 1 year, and unopened nail polish is good for 2 years.Changes in consistency, color and smell after opening are signs that the product has gone bad.o even in the US, you can look for the picto on the packaging of the product and it will give you a rough idea of how long you can use the product AFTER you open it.
