How does Bacteria grows into cosmetics? or in mascara?

Most bacteria in cosmetics, comes from a host. That's why you really don't want to let other people use your make-up. Another way is if it has expired it's shelf life or has been exposed to other elements, (Falling in water, laying in a hot car, etc.) that will promote bacteria growth. Alot of make-up usually consists of bat droppings(guano). So check the expiration dates, and only you should use your make-up.

Reply:Being exposed to the open air. (As Ive seen on The Tyra Show) Not keeping things in your makeup bag clean. And also using dirty sponges and brushes. Keep your brushes washed at least once a month with a mild shampoo and let them dry overnite.


Mascara well with all the air there is in pumping the mascara in and applying it on to your lashes (which catch your bacteria) its very easy for the mascara to get bacteria.
Reply:Our skin naturally has bacteria on it-and then there is the bacteria we pick up here and there= we touch our eyes, and rub, etc it gets on the make up brush, in the eyeshadow and makeup= it really likes to grow in the mascara since it is wet, damp- and pfobably dark-D
Reply:Our face, eyes, and lips have bacteria so when you put on your make up you touch your face or even if you just open it the air has bacteria so when you close the bottle the bacteria is inside so it just keeps dividing and then when it's really bad you get like a break out on your face your a really bad eye infection. It's true that's why you should only use make up for a short amount of time. Bye!!!
Reply:the same way bacteria grows on bread, stale water, etc. water also promotes the growth of bacteria
