Signs of Spoiled Cosmetics - Bacteria

This is the fourth part in our series of Signs of Spoiled Cosmetics.

Bacteria Build-up in Cosmetics

Simply opening any container exposes the content to bacteria, and cosmetics are no exception. When your applicator (hands, brush, wand, sponge…) touches your body, an object, or even the air, it collects bacteria. Then, when the applicator is put back into the product and stored away for later use, the attached bacteria is also stored.

While you can expect chemical preservatives to keep your products relatively safe when they are new, overtime preservatives age, weaken, and eventually lose their ability to effectively kill unwanted bacteria increasing the likelihood of cosmetics becoming spoiled.
