Time For New Makeup?


| 2 Comments

Ladies, how long have you had that lip gloss or mascara? Maybe you didn't know that makeup has an unofficial expiration date. The longer you keep make up, the more bacteria it contains. I found out the hard way by stumbling across a lip gloss that had the most unappealing smell. Make up isn't cheap and I know that throwing it out when it isn't even gone seems like a waste, but what exactly are we coming into contact with when we keep using that mascara that's been in the makeup bag for almost a year?

The most common bacteria found in makeup are Staphylococcus epidermidi (found in lipsticks, eye shadow, and eye liner), Staphylococcus warner, pseudomonas aeruginosa (found in mascara) and methicillin-resistant Staphylococcus aureus (MRSA).  These bacteria can cause something as mild as pink eye or skin irritation and as extreme as endocarditis if left untreated. Makeup has preservatives that slow down the growth of these bacteria, but they only last for so long. Here are some tips from Marie Claire on when you should replace your makeup.

Expiration dates -- beginning from the time you first open these products
Powders and shadows: 2 years 
Cream shadows: 12 to 18 months 
Foundation: 1 year 
Lipstick & lipliner: 1 year 
Mascara & eyeliners: 3 months 
Makeup brushes: Clean weekly using a mild detergent 
Makeup sponges: Replace weekly, or when sponge becomes soiled 

You should also smell your cosmetics before using them. If an unusual odor is present then that may mean bacteria is as well. Cosmetics should be kept out of sunlight, which can destroy the preservatives.

This is a great post for college girls! I think a good point to raise along with the very serious issues you pointed out is the fact that college students tend to be open about sharing things. This is why students are very susceptible to getting Mono "The Kissing Illness." Each time you touch a lipstick or mascara, you are potentially introducing germs to the product. And the more people who use it, the greater the likelihood of spreading infection. Dr. Jessica Wu says "Since mucous membranes are more susceptible to getting infected, lip and eye products should never be shared under any circumstances." She also addresses how Make up artist seems to get away with it, "While it’s true that makeup artists often use the same cosmetics on different people, several prominent makeup artists that I discussed this with all said that they take precautions to avoid contaminating their products. For example, they use disposable applicators to apply lip gloss and mascara, and disposable sponges to apply foundation and powder. All of the artists also said that they wash their brushes between clients, since, in addition to being more hygienic, clean brushes help makeup go on more smoothly and evenly."

With illnesses easily being passed around from student to student, I think girls should keep these points in mind and take extra precautions.

My mom has always been preaching to me about this. And it is so important to keep bacteria out of our makeup, not just for our complexion's sake, but to keep us healthy as well. I think the best way to keep your makeup bacteria-free for as long as possible is to ensure that applicators are always clean. They are the main carriers of bacteria, as they are what is coming into contact with skin. Cleaner brushes = cleaner makeup = less bacteria. And that is always a good thing.
