I don’t want to get too judgy about the whole thing because Reddit does list how you can sanitize used makeup items and all of that, and I am sure users are very careful about swapping things like mascara, which is an excellent idea because sharing makeup can be super dangerous. Here are a few reasons why makeup sharing is a bad idea:

Eye Products Are The Most Dangerous Items To Share 

The most common eye infection you can get from sharing mascaras and eyeliners is conjunctivitis, and sometimes re-sharpening an eyeliner isn’t enough to get it clean.

Lips Glosses And Lipsticks Can Give You Herpes 

According to Dr. Laurie Polis, MD, says this can cause herpes labialis, an infection caused by the contagious herpes simplex virus. That’s the virus that causes small painful blisters known as cold sores or fever blisters on the mouth. Sexy, no?

Other Makeup Products Can Cause Warts 

Dermatologist Dr. Vivian Bucay says you should never share anything that comes into direct contact with someone’s skin or mucus membranes because doing so can cause flat warts.

 My Own Doctor, Dr. Joanna, Who is Not Really A Doctor Says: 

You can get leoprosy and crumbs from other people’s lipsticks after they have eaten lunch.

You May Get Vulva Lipstick

Liz told me this, and even though she is NOT a doctor she makes a very valid point by saying:

People might use stuff for off-label purposes and then surprise you. Like, “Lipstick? No, I use that to make my vulva red.”

Dr. Joanna Claims People Make Makeup Brushes Out Of Things 

When Joanna had a break from surgery she told me that:

i make my own brushes out cat hair and won’t tell anyone, which could be an issue if you are allergic to cats.

Sam Escobar, Makeup Artist Extraordinaire And Concerned Citizen Reminded Me Of ACNE!

Due to other people’s skin oils and bacteria.

Plus, who knows exactly how old swap items are and whether or not they have reached their expiration date? All you Reddit swappers, get on with your bad selves but don’t come crying to me when your eyeballs fall out.
