Question: How long does unopened mascara last?
Answer:
Mascara has one of the shortest shelf lives of any makeup products you probably own. Once opened, mascara only lasts for about 3 months. The best way to make your mascara last longer is to not open it until you are in need of a new one. Unopened mascara can last for at least a year, maybe longer as long as it has never been opened and exposed to the air.
