Why is bacteriology important to a cosmetologist?

Hi Ruby, Cosmetics are very often wonderful growing media for bacteria. For example, lipsticks made in the US often have pig fat (lard) for shininess. Lard has triglicerides which many bacterial species can efficiently use as an energy source. The cosmetics are far from sterile and even if they are, their normal use will get them contaminated with bacteria. A cosmetologist needs to be aware of proper technique as cosmetics are applied very close to the eyes. Thus use of the same cosmetic in many people can lead to bacterial transfer from one person to another. Hope this information helps. Please feel free to revert.
