On Twitter, Police Capt. Marc Reina announced the outcome of the raid, adding that the fake cosmetics were "found to contain bacteria and human waste."
"The best price is not always the best deal!" Reina wrote.
The bust uncovered lookalike makeup in packaging similar to Urban Decay, NARS, MAC, Kylie Cosmetics by Kylie Jenner, and others.
The investigation started after customers contacted the actual cosmetic companies complaining of skin reactions from the products.
"They came back positive with high levels of bacteria and animal feces," according to a police detective. He added that legitimate cosmetic companies adhere to health and safety standards, which is costly. As for the bogus products, they are made where contaminants are rampant.
"Those feces will just basically somehow get mixed into the product they're manufacturing in their garage or in their bathroom—wherever they're manufacturing this stuff," he said.
