Expiration Point; Even if you've learned the basics of makeup freshness-toss a mascara three months after opening,foundation after six months- Lip gloss after 18 months- its not always easy to remember the particular dates. Place a small sticker on the new bottle, tube, or compact with the date you need to throw it out, as a good reminder. Put your germ fears to rest!!!
FYI, only nail polish and mineral powders are nonperishable.
