Makeup is used by a large portion of humanity and often misused or stored incorrectly, leading to contamination by microbes. The water content in cosmetics influences susceptibility to microbial contamination, which can represent health risks, as well as deterioration. The aim of this work was to isolate and identify filamentous fungi in samples of face powder, foundation, blush, and lipstick of eight popular brands in Brazil. A study of their composition identified a total of 106 ingredients. Of the products, 75% of the samples showed contamination by filamentous fungi. Penicillium was the most prevalent, followed by Rhizopus and Scopulariopsis. The presence of these pathogens suggests misuse in the production and manipulation of these cosmetics as well as high risk to users' health.
