Microbiological analyzes in cosmetic products are tests to evaluate whether the products inhibit the growth of microorganisms and whether they harm human health. These analyzes are important to ensure that products are hygienic and safe.

Microbiological analyzes are carried out to control factors such as the number of microorganisms contained in the products, the presence of yeast and mold. It is also examined whether the products are microbiologically stable throughout their shelf life.

Statements stating that products have undergone microbiological analysis can be found on product packaging or on websites. Phrases such as "Microbiologically tested" or "Microbiologically stable" are used to indicate that the product is microbiologically safe.
