A Microbiologist Just Confirmed The Gross Types Of Bacteria Living On Our Makeup Brushes

Raw meat, spoiled fruits and contaminated veggies are typically the places you would expect to find the bacteria responsible for serious strains of food poisoning: E.coli.

However, according to microbiologist Amy-May Pointer (who carried out a study for PrettyLittleThing), it turns out E.Coli, amongst other bacteria, is turning up (uninvited) in our beauty cupboard. 

During the petri dish experiment, comparisons between frequently-cleaned beauty tools, including sponges and brushes, were up against ones that were rarely, if ever, washed.

Within these findings were bacteria responsible for skin conditions as severe fungal acne, which appears in the form of itchy, inflamed blemishes. 

Comparing the results side-by-side, the regularly cleaned example had just one organism growth compared to the uncleaned example, which indicated an extremely high density of bacterial growth including E.coli and differing types of Staphylococcus epidermidis (S.epidermis).

And according to Amy-May, “S. epidermis is found as part of the normal skin microbiota, but also has been found to contribute to the inflammation of acne”. 

E.coli, on the other hand, is not found in our normal skin microbiota but actually originates in our gastrointestinal tracts. 

So, the explanation for its cameo on our makeup brushes? You guessed it, fecal matter (gross, sorry, we know). 

In short, if you’re storing your brushes or sponges near a toilet in your bathroom, we suggest you go and conduct an immediate rescue mission. 

If these findings have urged you to go conduct a deep clean on every beauty brush and blender you’ve ever laid eyes on, here is our step-by-step guide on how to clean your makeup brushes properly.

And for every time in between, keep Isocol Rubbing Alcohol Antiseptic ($6.29 at Priceline) in your kit to wipe them down after each use.

  1. Another good reason to continue using my clean fingers to apply my foundation. The example above doesn’t mention if the brushes were used for applying foundation or powders (translucent; blush & eyeshadows etc).

  2. I rarely wear makeup, so I always cleanse my brushes (& sponges, if I’m using them) after I’ve worn makeup as I don’t know when I’ll be using them again & would want them to be clean.

  3. Eeewwwww yucky! I never ever touch any of my makeup or skincare without washing my hands first. I clean my brushes with a brush cleansing spray after each use, and give them a deep clean every couple of weeks. And there’s no freaking way I’d leave them in the bathroom, because hubby also uses that bathroom and he is a total grot! They are all hidden away safely.

  4. I was not at all surprised to read that. Everything stored in you bathroom would have faecal matter on it sooner or later. That is part of the reason to clean them and either put them in another room or in a cupboard.

    Did anyone else watch that mythbusters episode of the toothbrush stored in the bathroom experiment?

  5. Don’t use sponges. And from brushes only powder brush that I use rarely to get the grease look off my face when wanting to look more normal. Look, never had issues with “bacteria”. We are friends.

  6. Fungal acne is not bacterial, I think there was a bit too much cutting down from the original report! Most of these aren’t likely to be an issue for most people but it’s obviously a good idea to reduce exposure where you can. I’m not a big brush user but I think it might be time for a big clean.

  7. I must admit that I dont have a set routine for cleaning my makeup brushes but I do have two sets and tend to sideline one set until i get the urge to clean them and then I tend to do them all in one hit.

  8. I’m fortunate that my daughter gives my brushes a regular clean, she’s grossed out at the fact that I don’t bother. My brushes stay out of my bathroom. Makeup sponges are a breeding ground for all sorts of stuff. I’m never convinced they get a thorough clean and prefer to use my fingers.

  9. So disgusting. Thankfully I clean my brushes regularly and I have never at any point stored them in the bathroom. I don’t store anything makeup related in the bathroom. I don’t even store my moisturiser in the bathroom.

  10. Definitely a reminder for me to always clean my sponges! I currently wash them at least once a week with detergent and oil. So far, it does the work by removing majority of foundation.

    If anyone has other ways to clean them, feel free to reply!
