I’m not trying to freak you out but many makeup products provide the perfect breeding ground for bacteria! So no you DEFINITELY SHOULDN’T use that eye shadow that you’ve found at the bottom of your makeup case that is at least 5 years old!
Below is the expiration period for different makeup products and why. The time period I give starts once the product is opened.
Liquid Face and Eye Makeup
including: foundations, concealers, highlighters, cream blush and cream eyeshadow
Liquid makeup products contain water which provide the breeding grounds for bacteria. It also tends to separate after some time and the oil rises to the top which causes it to be applied with an inconsistent finish.
Powder Face and Eye Makeup
including: foundations, concealers, blush, bronzer, finishing powder, highlighters and eyeshadow
Powder makeup contains only trace amounts of water so bacterial growth is minimal. Over time powder products become harder to blend and crumbles due to the evaporation of this water. Ageing eyeshadows may become hard to use as they are packed down and brushes may not pick up the product as well. If you wet your eyeshadows they should be thrown out after six months.
Mascara and Liquid Eye Liner
Mascara and liquid eye liner are the wettest makeup products so bacterial growth inside the tubes is rapid. Mascara dries out quite quickly and starts to form clumps upon application due to the lengthening and thickening fibres separating from the fluid which occurs around the three month mark. To slow down the rate at which mascara and liquid eye liner dry out, don’t pump the wand in and out of the tube. Instead remove it slowly while twisting the brush to pick up the product.
Eye Liner and Lip Liner
Liners last longer as every time you sharpen them a clean surface is revealed and the amount of bacteria is reduced. They also don’t contain much water so bacteria growth is minimal.
Lipstick and Gloss
Lipsticks and glosses are applied directly to the lips so they pick up the bacteria that is on them. Lipsticks dry out with age and they no longer look creamy after about two years. Some long-wearing lipsticks may have a shorter life as they contain ingredients that evaporate more quickly than in regular lipsticks.
Being hygienic when dealing with our makeup application is extremely important as products containing excess bacteria can cause skin irritation and break outs
- wash your makeup brushes and applicators, including eyelash curlers and liner sharpeners, at least once every two weeks
- avoid dipping brushes, applicators and fingers into makeup products, such as liquid foundation as this will increase the spread of bacteria
- if you used your fingers to apply your foundation make sure you wash them first!
- avoid touching products, such as lipsticks, directly to your lips when you are sick as this will increase the amount of bacteria on them and may cause deterioration of the lips if used again in the future
- mark each of your products with either the month and year that you purchased them or the month and year they expire. Go through your makeup case once a month and throw out the products that have expired
- remember: if in doubt, throw it out!
