Lipstick can last up to two years.
True. But don't use it beyond that date as the moisture content can lead to bacterial growth. Lip, eye and lash liners have a similar shelf life. But you'll have to sharpen them often and remember to wash your sharpener every time you use it!
Mascara is one of the products with the shortest shelf life.
True. Dark and humid... a mascara tube is the ideal environment for bacterial growth. So you should change yours every three months just as you would with your liquid liner or concealer.
Foundation can be kept for 2 to 3 years, like loose powder, eye shadow or blush.
True… But only if it's powder! Given its low moisture content, powdered foundation accumulates bacteria more slowly than liquids, as long as you only use clean brushes. Liquid foundation, however, should only be kept for 9 months.
Body moisturizers last longer than face creams.
True. They can last up to a year, while face-care products (creams, cleansers, scrubs and masks) only last 6 to 9 months. In both cases, you should always check your products carefully: certain ingredients evaporate more quickly than others, making the product more concentrated than it should be, which increases the risk of irritation.
