What is acne?
The medical definition of acne is “a chronic inflammatory disease of the sebaceous glands in hair follicles.” Acne is a multifactorial disease of the upper body sebaceous glands, especially those of the face. Cutaneous Propionibacterium acnes (P.acnes) are slow-growing anaerobic bacteria and may be unable to multiply in follicles in which the sebum excretion rate is high as end products of bacterial metabolism escape with the out-flowing sebum. When a follicle becomes blocked, it behaves as a closed culture system from which bacteria cannot escape. From this point on the inflammatory response starts.
