I have a pet peeve, anyone who knows me knows what it is….it is when people don’t wash their makeup brushes. If you knew what kind of bacteria was growing on your brushes after not washing them for months, there is no way you would put it on your face. What is even worse is when you use a dirty brush and dip it into an eyeshadow, you have just transferred more bacteria onto the eyeshadow and it just goes around and around. You should be washing your brushes WEEKLY or at the least, every two weeks. It’s so simple to wash your brushes – there are some good brush cleaners out there but you can use a mild baby shampoo and save some money. Make sure to lay your brushes flat to dry and don’t completely immerse the brush handle in your baby shampoo/water mixture or you will loosen the glue.
There are no regulations for cosmetics that makes them put an expiration date on the bottles so here are some guidelines.
Mascara has the shortest expiration and should be thrown out within 2 1/2-3 months. Don’t “pump” the wand in and out of the bottle because you think you are getting more product by doing that, you are actually pushing more air into the bottle and giving a chance for more bacteria to get in the bottle. Keep bacteria away from your eyes!
Foundation also has a short lifespan. You really should throw it out after 3-6 months depending on how big the opening of the bottle is (letting more air in). Now since foundation goes ALL over your face, don’t add more bacteria onto your face than you have to. Also, keep your fingers out of the bottle – use your CLEAN foundation brush! Concealers can last a little longer (the thicker it is, the longer it can last) so throw it out after 6-9 months.
Now, to cheer you up, powders (pressed, blush, eyeshadow, etc) can last up to a year. I spray mine with 99% alcohol every once in a while because it can’t hurt and it will kill bacteria. Lipstick, lipgloss, lip liner, eyeliners can also be thrown out after a year but make sure you are sharpening your pencils every week to get that first layer of bacteria off and spray with alcohol once in a while.
Just make sure to pay attention to the consistency of your products and the smell. If it changes color or starts smelling funny – throw it out! Breaking out from the bacteria festering in old products/brushes does not make up for the money you would spend on buying new stuff or cleaning them…at least not to me!
