We ladies are guilty of sharing some of our beauty products with our girlfriends, especially when we run out of ours or want to try something different, like a new facial or lip look, etc. but don't have the needed tools. I have listed some beauty products to share and not to share for your reference.
DO NOT SHARE
When it comes to sharing beauty products, things associated with the eye like the mascara should not be shared because of eye infections or irritations like red eyes.
A lot of us are guilty of sharing mascara. I am very careful with anything relating with my eyes probably because I use glasses.
Funny as it may sound, sharing lipsticks or balm is dangerous. Reason being that germs are transferred from one skin to another. Whether you like it or not, you already have enough germs around you when using it, so why share what makes direct contact with your skin with another person. A lot of girlfriends are guilty of this.
Having said that it's not okay to share lipsticks, you may think sharing lip glosses are okay. No, it isn't and shouldn't be shared.
You will agree with me that makeup brushes have direct contact with your face and thus has germs in them. Everybody has different types of skin. While some can resist certain facial irritations, some can not. Sharing make up brushes can result in acne (pimples) breakout, rashes and other skin irritations.
YOU CAN SHARE
It is okay to share it because your sponge does not make direct contact with the whole foundation's surface but just the top of the tube. So it is okay to share.
