Your favorite eye shadow has been discontinued by the manufacturer. You’ve managed to extend the life of your palette for three years, but at what cost? Have you thought about the wide array of microbial growth that could be hiding in the shimmery square of gold shadow?  An unkempt makeup bag is a scary thing. Old makeup and rarely cleaned brushes create a haven for microbes that could result in eye and skin infections.

Consumers are responsible for throwing out old makeup, but manufacturers also have a significant role to play in keeping cosmetics safe. Proper testing methods must be followed to ensure their products are free of contaminants.

Take our cosmetics quiz to test your knowledge and learn more about microbes and makeup.

Good luck!
