Comedogenicity

The term comedogenicity is often called “pore-clogged” relative to product ingredients. This may mean the ingredient blocks dead skin cells in pores or that the ingredients tend to form small plugs of oil. Generally, those most susceptible to comedogenicity are those with oily or acne-prone skin. Many oil-free ingredients can still be considered comedogenic. Comedogenic ingredients may also be included in products without resulting in comedogenicity when the formula intended for either areas that are not prone to comedogenicity or skin types that are not normally susceptible to comedogenicity.
