How often to replace: 1  Mascara: every 3-6 months (which means youâll have to throw it away before itâs used upâ¦ the same goes for a lot of these products, probably) 2  Eye shadow: every 6 months. 3  Eyeliner (liquid): every 3-4 months. 4  Eyeliner (pencil): every 6-12 months.
Â· just now. Report Abuse. Lipgloss is much more flexable with when it expires then say foundation or mascara. The smell test is the best way to know. some products start to go off after a year. as a makeup artist i would suggest not keeping anything around longer then that. Because they say lipgloss lasts about 2 years.
