Your makeup has an expiration date; even the products that you use sporadically. It is imperative to dispose of your old make-up. Yes, throwing out your Lancome mascara after it has only been sitting in your makeup bag for 9 months seems extreme. However, the consequences of using old make-up are not worth saving a few bucks. Bacteria accumulates on your brushes, wands, eyelash curlers, powders, lipsticks, lipglosses, etc. Using bacteria laden products can result in breakouts, rashes, redness, inflammation, pinkeye and many other avoidable conditions. The reason makeup doesn’t have an expiration date is because there isn’t a high risk for bacterial growth until the product is opened. It is recommended that you record the date when you opened your product(s). You want to especially note the date that you open products that are used on your eye area and the lashes.
According to the FDA, products used for the eye area have repeated microbial exposure. It is best not to “pump” your mascara because it forces air into the tube. If your mascara begins to dry out don’t attempt to restore by adding liquids of any kind. Throw it out. Organic or natural mascaras should be discarded within a two month time period. Note that naturally derived products contain a different type of preservative or may even lack preservatives. While expiration dates can be reduced or stretched based on the user’s care, it is recommended that all makeup products are discarded after 1.5 years. Mascaras and liners are the exception, and should be kept no longer than five months. If you are prudent, mascaras should be replaced every two- three months.
Keep in mind that you should always wash your hands and face before applying makeup; this will help extend the shelf-life of your products. Never share makeup with friends or family. Make-up is for personal use. If you choose to share, use a clean tool and do not dip twice.
