Austin-based Dermatologist Dr. Ted Lain breaks it down: “A study was performed in 2008 where researchers cultured the contents of mascara tubes after three months of use. Nearly 40% of the tubes exhibited contamination with either a bacteria or fungus. Based on these results, I recommend replacing mascara at least every three months. Users can minimize their risk of contamination by washing their faces with anti-bacterial soap prior to applying the mascara.”
ICK! This is terrifying! I seriously know the struggle of not only remembering when to change out your mascara but the cost associated with it. This L’Oreal Paris Voluminous Original Mascara in Carbon Black is a favorite of makeup artist Mario Dedivanovic, who works with celebs like Kim Kardashian.
It’s only $5.60 on Amazon, and you can sign up to have it delivered automatically to your house or job every three months. Subscribing saves you money PLUS reminds you it’s time to change out your mascara — easy.
How Often Should You Change Mascara — Every Three Months Experts Say
Celebrity Dermatologist Dr. Dendy Engelman explains to HollywoodLife.com: “Beauty products are designed to stay fresh for a limited period of time; we call that a shelf life. The reason is once you break the seal of the product, you’re exposing it to air, dust and bacteria, which festers and grows in dark, moist areas.” The bathroom, anyone?
“It is especially important to be mindful of products like mascara, as it’s liquid, used near the eyes, and most importantly, every time you re-insert the brush back into the tube, you’re essentially pumping more air and bacteria into the tube. Using old mascara that has gone bad can lead to eye infections and conjunctivitis. Here is a new one I like — Elizabeth Arden Grand Entrance Mascara.”
Dr. Elizabeth Tanzi, Founder & Director of Capital Laser & Skin Care and Assistant Clinical Professor, Department of Dermatology at the George Washington University Medical Center agrees: “It’s important to toss old mascara because it can become contaminated with bacteria and getting that near your eye is not a good idea!”
This is seriously making us question our makeup bag. And it’s another reminder to keep everything clean, especially your makeup brushes.
