Acne develops as a result of blockages in follicles. Hyperkeratinization and formation of a plug of keratin and sebum (a microcomedo) is the earliest change. Enlargement of sebaceous glands and an increase in sebum production occur with increased androgen (DHEA-S) production at adrenarche. The microcomedo may enlarge to form an open comedo (blackhead) or closed comedo (whitehead). Increased sebum production provides an environment for the overgrowth of Propionibacterium acnes. Bacterial overgrowth of Propionibacterium acnes can cause inflammation, leading to inflammatory lesions (papules, pustules, or nodules) in the dermis around the microcomedo or comedo, which may result in scarring.
The reasons for back acne are the same as face acne. The reason why you get back acne can be from hormones, stress or clogged pores. This is not due to being unclean which is a common myth. This is usually due to physiological problems with bacteria caught in your pores or hormones causes stress to your skin.
