Acne vulgaris can present in various forms such as pimples, papules, pustules, and nodules. Sebum provides an anaerobic environment for the growth of microorganisms such as Propionibacterium acnes. Propionibacterium acnes hydrolyzes the triglycerides in sebum to free fatty acids, which stimulates the proliferation of keratinocytes in the follicular ducts and over-keratinization of the keratinocytes, which blocks sebum excretion, resulting in the formation of comedones when sebum and keratin plugs accumulate in the mouths of the hair follicles.
