The fake products included brands such as Kylie Jenner's Kylie Cosmetics, Urban Decay, MAC and NARS.
Police in California raided 21 locations around Los Angeles after customers who bought the products complained they were giving them bumps and rashes. The Los Angeles Police Department, LAPD just seized $700,000 worth of counterfeit makeup for traces of feces.
Counterfeit makeup isn't always easy to spot, but as a general rule of thumb - if it's too good to be true, it probably is.
Officials said some of the products were contaminated with bacteria and human waste.
The packaging for the fake products is nearly identical to the real deal, so it's hard to tell if a product is a unsafe counterfeit or it is the real deal.
The police arrested six people in relation to the investigation. She then advised buyers of the cosmetics line to "never buy counterfeit products!" The products were tracked to the Fashion District, where officers did undercover buys.
"If you're getting something that's 50% off, 75% off, it tells you that it's bad", Ishitani said.
Counterfeit makeup is super unsafe because you don't know what ingredients are in the products and they aren't held to any regulations. Fifteen other people caught in the raid were served with cease and desist orders.
There have been reports that some fake lip kits also have glue in them.
