Eyeshadow
Bin it: Every two years for powder, once a year for cream.
Why? Just like powder blushes and bronzers, powder eyeshadows can last up to two years. But if you apply it every day, beware that bacteria build up could result in an eye infection (not a good look), so be sure to keep brushes clean. If you’re using a cream-based eyeshadow toss it after one year.
Liquid Eyeliner
Bin it: 3-6 months.
Why? Bacteria is again the culprit for liquid liners. Pencils and retractable pens can be kept for a year as they are constantly sharpened.
Foundation
Bin it: Once a year.
Why? Don’t use your fingers! Nasty bacteria loves your fingertips. If you use a brush or a sponge you can get a full year out of it. At that point colour changes.
Concealer
Bin it: 12 to 18 months.
Why? If you have concealer in a pan, it can last up to 18 months if you apply it with a regularly-washed brush or sponge. If you apply with your fingers, though, you’re more likely to transfer bacteria. If you have concealer in a tube with a wand you’ll only want to keep it in your makeup bag for a year before it starts to turn.
Blush & Bronzer
Bin it: Every two years.
Why? Powders, since they don’t contain oils and water, have a longer shelf life than most other cosmetics. As a rule of thumb, toss these when the colour darkens or starts to cake.
Lipstick
Bin it: Once a year.
Why? The preservatives used in lipstick can break down after a year.
Lip Gloss
Bin it: 6 months to one year.
Why? Lip gloss with a wand applicator should hit the trash after 6 months due to bacteria build up. Tube gloss can last a year because of the decreased chance of bacteria entering the product.
Makeup Brushes
Bin it: One to five years.
Why? It’s all about the quality. A good brush that you take care of can last for many years. Wash brushes every day. Pro-tip? Johnson’s baby shampoo works well too thanks to its gentle formula.
Makeup Sponges
Bin it: At least once a month.
Why? If you wash them after every use you can get a month out of them.
