I'm sure you already know the reasons why you are better off not using expired makeup. The good news is that it can be very simple to keep track of when to toss the old stuff.
1. Write down the expiration times for your makeup. Keep this note somewhere near your makeup. This can be a full-sized sheet like the one in the pic below. I attached this to the inside of my bathroom cabinet for easy reference. It can also be a simple as a post-it note in your makeup bag.
2. Note the expiration on your makeup when you purchase it. It is great to know how long to keep something (see step 1!), but that only helps if you recall when you bought it. I like to use price tag stickers that I got from the Dollar Tree and a Sharpie for this job. Works like a charm.
3. Congratulate yourself on using fresh makeup. Your face will thank you! :D
Do you keep track of your makeup's expiration? If not, will you start today? Please share in the comments!
