So, uh, Laura Lee just reviewed a bunch of counterfeit beauty products — and it immediately bothered me.

Why? Apparently, the "full face of fake makeup" challenge is a thing.

In which — you guessed it — vloggers purposefully buy counterfeits to see how they stack up to the real thing.

And although some of these videos make a very good point (that fake makeup pales in comparison to the real stuff), most of them fail to clarify one MAJOR thing.

Buying cheap makeup from an unauthorized retailer is really fucking dangerous.

YouTubers might write a brief warning letter in the description box, but let's be real — not very many people will bother to read that.

"In today's video I am testing a FULL FACE of only FAKE MAKEUP," reads the description of this video. "Please do not try this yourself, fake cosmetics can be extremely dangerous and harmful, I am just eager :)"

Some of these videos actually walk a fine line between reviewing and recommending counterfeit makeup.

And that's just NOT OK, especially when the viewers in question are young, impressionable, and likely looking for a bargain.

Because fake makeup is made with blatant disregard for FDA regulations and contains hazardous chemicals that can mess up your skin, hair, and eyes.

Even Laura Lee admitted after filming her video that her face broke out in hives. It's likely the makeup she used contained lead, arsenic, mercury, or just a lot of bacteria.

So if a vlogger ever suggests that a knock-off product is actually good, take it with a grain of salt.

Actually, a GALLON of salt. Don't buy that crap.
