What’s In Your Expired Makeup?

Описание: I’m the worst! I keep makeup FOREVER! Call me frugal, but it’s hard to part with a 6 year old lipstick when there’s still something left in the tube! I’ve always wondered if expiration dates were just a way for cosmetic companies to get us to buy more stuff or if there was really something nasty lurking inside. Instead of sitting around and wondering, I got off my duff and used science to put my makeup to the test. You won’t believe what I found out!

😀Fun Facts😀

Unable to distinguish between species of bacteria, Swedish botanist Carolus Linnaeus originally classified all bacteria in the order Chaos (1763).

When it comes to bacteria --you can’t see them. They’re microscopic. This makes it hard to know when your cosmetics should be thrown out and is why some cosmetic manufacturers offer expiration dates.

Expiration dates are a rule of thumb and can vary depending on many factors, including how makeup is stored (sunlight can break down ingredients), handled (unwashed hands can cause makeup to expire sooner), and ingredients used (some botanical extracts, carbohydrates, and proteins act as nutrients for bacteria).

In this video, we used chromogenic AKA color producing agar so we can identify what genus and species the bacteria belong to.

Not all bacteria are trying to kill you! In fact, many bacteria naturally live on your skin (commensals) and many indirectly help us by crowding out more harmful bacteria (pathogens).

The biggest contaminator of your cosmetics is YOU! When you dip your finger into your lipgloss, you’re also adding some of your own microbes (bacteria, fungi, yeast)

In most healthy adults, a contaminated product might not yield a bad effect, but for those with compromised health there could be severe consequences.
